Pros: "Service was fast"

Cons: "Better seats"

Cons: "The main economy seats were far too narrow."

Pros: "I always have a consistently good experience on Delta. Everything was great."

Cons: "It was a Great flight. I always enjoy flying Delta"

Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."

Pros: "non stop flight"

Cons: "Crowded, small plane. No air after people had boarded while fuel was being replenished (dangerous?), sitting at gate for 20minutes. This, after a 2 hour delay. Then a rough landing in Minneapolis- plane brakes sharply and suddenly, shuddered to a taxi rate of speed. simple snacks, not very good."

Pros: "Nothing"

Cons: "Worse experience ever, flight delayed, lost connection, many hours in phone trying to fixed and anyway lost the flight, spent so many time at the airport with the front desk so disappointed"

Cons: "Flight was delayed and completely packed so our family could not get seats together"

Cons: "When we booked this trip via Kayak, we thought that we were booking on Westjet. Westjet knew nothing about the flight when we tried to check in."

Cons: "Plane had to divert from Salt-Lake City due to a storm. My son 17 years old traveling alone once in Salt-Lake City should have been given priority for an overnight stay instead of sleeping on an airport bench! Dinner + Breakfast vouchers would also have been nice compared to the 15$ food voucher..."

Pros: "Love the fact that the head rests move to support your head better."

Pros: "The flight attendants were amazing. 12 people had a connecting flight and they brought a shuttle bus. You dont see that kind of service any more 10 stars for that"

Cons: "Super small plane."

Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."

Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."

Pros: "Boarding was easy."

Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."

Pros: "I liked the touch screen displays in each headrest. Seats and leg room comfortable"

Cons: "Boarding was somewhat unorganized"

Pros: "The crew"

Cons: "Timing"

Pros: "Entertainment"

Cons: "Boarding at JFK.Always messy"

Pros: "Boarding was quick"

Cons: "No entertainment, plane was small"

Pros: "Good entertainment selection and great crew"

Cons: "Seats are more uncomfortable relative to other airlines"

Cons: "First delay notification: 1 hour 20 minutes 1 hour later, Second delay notification: 3 hours 15 minutes 2 hours later: Third delay notification: 3 hour 50 minutes Fourth delay notification: 4 hours 25 minutes Fifth delay notification: 4 hour 32 minutes No explanation for reason. Last time flying Delta."

Pros: "The kind staff"

Cons: "Dirty bathroom on flight from Toronto Ontario to Atlanta. Smelled like urine."

Pros: "Early and middle seat was open!"

Cons: "Coffee tasted like fish. :("

Pros: "Entertainment choices were excellent, many new movies available, so I was able to see movies is been meaning to watch. There were drinks available."

Cons: "The air vents barely trickle out any air anymore. No relief to be had. Airline crews say hi and goodbye but that doesn't make them friendly."

Pros: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"

Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."

Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."

Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."

Pros: "The movie selection was good"

Cons: "Instead of a flight from Toronto to Atlanta.. it was a flight from Seattle to Atlanta, and I only had 45 mins to get to boarding because of the last minute flight changes."

Cons: "Very little leg room."

Pros: "JFK to Denver the flight Attendants were once again great. Lots of entertainment choices again. The usual rough air coming into DIA."

Cons: "From JFK to Denver the seats were to close for leg room by an inch or two. The temperature was hot most of the flight."

Pros: "Airline and airport staff were great"

Cons: "There was no time to eat. Nothing other than snacks. The time allotted was *barely* sufficient to get from gate to gate. We were starving when we got to our destination."

Pros: "Love the built in tv’s with free entertainment."

Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."

Pros: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"

Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."

Pros: "It got me home, eventually."

Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

Cons: "Check in lines were crazy long"

Pros: "The crew tried their best. The seats were average. The food ok."

Cons: "The entertainment is non-existent. Wifi wasn't even enabled. Four to five hours without ANY entertainment is totally unacceptable especially with teens and kids!!"

Pros: "Delta flew their way back into my heart this time around"

Cons: "My daughter was stuck in SLC for 5 hours because there 1 cancelled flight and 1 delayed flight. It was very upsetting not knowing when she going to arrive in Denver."

Pros: "Staff, Ease of boarding"

Cons: "Bring back in flight meals, please"

Pros: "First leg from San Diego was excellent."

Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Pros: "The food"

Cons: "No entertainment"

Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

Cons: "West Jet gave me a "fake" ticket delta would not let me board missed the flight I had to wake up at 3am to catch. This is after I finally made it to my hotel last night at 11:30 pm. This is completely unacceptable. NEVER AGAIN IN MY LIFE WILL I EVER FLY WITH THIS COMPANY!!!!"

Pros: "The boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."

Cons: "Economy is very tight quarters."

Pros: "The plane, crew was clean, newer and had TV's in the backrests. Remember to bring headphones! Seats are tight, but the crew was friendly and may the flight experience positive."

Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"

Cons: "For a long flight perhaps a little more in the snack department."

Pros: "Crew was all very nice"

Cons: "Flying is always uncomfortable"

Pros: "The flight attendants were helpful, the flight was smooth."

Cons: "I was unable to check in online without a delta confirmation number and I had booked through west jet. The flight was delayed 40 min so I arrived later and I was removed from the flight. I got through security and customs with plenty of time and managed to get back on the flight. It was all around just annoying."

Pros: "Staffing was great!"

Cons: "The fact is that it is illegal to pack Sardines at compact as you are packing us on your aluminum cans."

Pros: "Free in flight entertainment"

Cons: "One of my bags went to Santa Fe"

Pros: "The flight being on time, friendly staff, clean aircraft.i"

Cons: "It was a morning flight from Toronto to Omaha via Minneapolis and unfortunately coffee wasn't served. Or maybe it got over."

Small plane. Premium seats not premium

See previous comments

Pros: "They cancelled the flight"

Cons: "How about a refund?"

Cons: "no food available to be purchased. we left almost 2 hours later than scheduled and were very hungry."

Pros: "the crew was great"

Cons: "reason for delays could have been communicated earlier"

Pros: "The service was really good"

Cons: "The waiting at the gate"

Cons: "Seat assignments. My husband and I were not assigned seats together, however we were able to sit together because the seat next to me was empty."

Pros: "Crew and staff at gate fantastic. Accommodated me sitting with partner on both legs (booked flights separately)."

Cons: "Flight was delayed. Always tough late at night."

Pros: "Premium seats were more comfortable, crew in our section was great, newer airplane was lovely, food and drink were really good."

Cons: "Can’t think of anything within WestJet’s control that was bad."

Pros: "Crew"

Cons: "Delay"

Cons: "was delayed by an hour"

Pros: "Friendly staff And I love it you go direct to Belize."

Cons: "We didnt have enough time to make the connection between the fly . We ran for all aeropuert and almost loss the fly to Lax"

Pros: "Easy to change flight same day to one flight earlier."

Cons: "Forced me to check in my (undersized) duffel bag carry on. Then forgot To load the bag onto the plane. WestJet cited a questionable and unlikely reason, that the bag was not loaded due to baggage to passenger weight ratio for safety reasons, even though flight was far from full with multiple empty rows. Plus there was a grand total of only approximately 12 pieces of baggage at the carousel. Also the plane’s auxiliary power generator was broken, which meant no a/c while on the tarmac before and after takeoff. Cabin was warm though not intolerable, however led to delays at both origin and destination airport due to having to wait for an external power supply truck. No in flight service due to supposed turbulence. Which would have been fine, except there really wasn’t much turbulence. Didn’t affect me, but my neighbor’s entertainment system was broken. However, these multiple issues and the broken power generator makes me wonder about what other maintenance issues have been overlooked or not addressed. Most of all I was offended by the clear lack of honesty about my baggage. If there really was a weight limit safety issue despite the plane being far from maximum capacity, then there are much bigger issues with the plane that makes me never want to fly WestJet again. But don’t insult your passengers by lying to cover up your carelessness. My baggage arrived on the following (my original) flight, but that which was delayed by nearly two hours. I’ve flown on United, Delta, Southwest, JetBlue, WowAir, AA, Alaskan, Virgin, American Airlines, United Airways, China Air, EVA, and Air Canada. So far, WestJet has been by far my worst experience."

Pros: "Decent flight."

Cons: "Entertainment system did not work. Also they said there is USB sockets at your seat but there were none."

Pros: "More leg room in seat than expected."

Pros: "Everything. Extremely polite flight attendants Clean plane Great service"

Cons: "Nothing"

Pros: "Flight attendants, movie on board, price"

Cons: "Plane was delayed and the baggage handlers in Denver were Atrocious!! I actually took video I was so shocked!"

Pros: "Great flight. It was like the plane wasnt even moving !!"

Pros: "Excellent service and smooth flight!"

Pros: "Airport counter staff v helpful. Crew were great. Helped lady with 2 kids. Looked after 1 while mom changing other."

Cons: "Need more seat room. No entertainment."

Pros: "I always use Kayak to book my flights! The website is user friendly and the prices you see are round trip. WestJet is fantastic! Service is great, the seating is spacious for the price. Always seems to be on time or early arrival."

Pros: "The crew on the ground and in the air were great. So helpful and upbeat. Every attempt was made to ensure our comfort and safety."

Cons: "I was in a window seat next to a small child and her mother. They were both lovely, but I couldn't move for the bulk of the trip because they slept most of the way. Not the fault of the airline of course, but if there was a bit more leg room, it would have been a less claustrophobic trip. I used to fly a lot back in the 70s and early 80s and I don't remember ever being so uncomfortable. I have another trip flying back home at the end of the week, and, quite frankly I'm dreading it. Also, it was impossible to hear the captain's address, the on-board instructions, or various other announcements, in the airport and on the plane. Especially on the plane; the speakers were far too quiet to hear anything the captain said other than it was a nice day."

Pros: "Lacking social skills ! One on the flight attendants had numerous holes in her sweater. So unlike most West Jet employees!"

Cons: "Unprofessional! Lazy ! Very ungroomed ! I thought this was the worst two flight attendants l have ever seen with West Jet ! Had this been my first flight, I’d never return! Lots of options to fly with other air lines. That was flight from Toronto to Ottawa. Now the flight from Tampa to Toronto, the female flight attendant in the Plus section was an “ air head “ ! I had preordered the chicken salad & since l was in the plus section on the plane l paid more willingly and when l asked for the cheese & grapes container, she rolled her eyes, came back with the food & no knife and fork to eat the salad ! I tried to get her attention & since that didn’t work, I used the buzzer! I politely asked for a knife & fork to eat the salad! The young flight attendant had trouble processing the information so l very politely repeated my request! Lordie, it was training day at West Jet !"

Pros: "The stewards were great however no TV anymore and meals because of cost cutting was where we thought it was lacking."

Cons: "Refer to above :"

Pros: "Wifi"

Cons: "Nothing"

Pros: "The crew was so friendly. They offered to check bags for free at the gate which is awesome because I didn’t have to worry about finding space in the overhead bins when boarding."

Cons: "Flight was delayed an hour, but it was due to weather, so it is really out of westjets hands."

Cons: "i know i am tall and above avg wt. but not enough leg room for anyone over five foot six inches."

Pros: "Best airline for friendly caring staff. Favorite carrier."

Cons: "The contracted ground crew at the desk in Puerto Vallarta were not very organized. Checking in took longer than it should have."

Cons: "It didn't happen"

Pros: "When I stepped onto the plane, there was someone there to greet you. That was nice."

Pros: "The crew tried their best. The seats were average. The food ok."

Cons: "The entertainment is awful to non-existent. The wifi doesn't work especially on a laptop. On the return flight is wasn't even enabled. Four to five hours without ANY entertainment is totally unacceptable especially with teens and kids!! The 20 schedule changes and very confusing schedule (they showed us on 2 separate flights from DTW on Dec 25th morning). I have no idea how that would happen. The gate agent at Delta (first leg) had a hell of a time sorting it out despite a long call to the WJ help desk."

Pros: "Nothing"

Cons: "Everything"

Pros: "very amusing male steward! (welcome to westjet flight xxx to cancun!")"

Cons: "well, someday i hope to be able to experience "first class!" travel, but all in all, quite adequate! i always try to fly westjet in canada."

Pros: "Was very windy when leaving Hamilton but the captain handled the flight so smoothly that I was able to sleep through most of it!"

Pros: "The staff was outstanding from the minute we arrived in Hamilton till we got to Edmonton. So impressed with the customer service."

Pros: "Flight was great! Just a bit slow on boarding, that ok , I understand. Out of Hamilton but better than Toronto."

Cons: "Arriving at Orlando, Real confusing and I'm not really old yet. Good thing we had people to meet us, I had no idea where to go."

Pros: "West Jet employees for the most part went the extra mile to ensure eveyones comforts, needs and safety. The booking with Kayak was a recommendation from a friend who I can't thank enough. Made what was an uncomfortable journey much easier."

Pros: "The staff were so helpful to travellers with small children and elderly travellers. They looked like they really enjoyed their jobs...Well Done Christine S North Vancouver"

Pros: "food, flight crew, leg room"

Cons: "crying babies"

Pros: "Pleasant staff and adequate leg room."

Pros: "the connection time in Calgary was short, so overall the trip was verily quick. Generally, the flight was good, clean plane, good services."

Cons: "There was no food for sale on a 4 hour flight from Hamilton to Calgary the flight left at 6:30 a.m., meaning that one had to be at the airport by 5:30 a.m., and for me leave where I was staying an hour before that. It was a connecting flight in Calgary with almost no time in the airport so I didn't get to eat until I arrived in Nanaimo at 1:15 p.m., Ontario time. for health reasons - I'm diabetic, I wish I had known that no "real" food was available. I got a snack which I read had 50 calories, and I got a juice which I normally won't drink to maintain blood sugar levels."

Pros: "Great flight. Westjet got me home earlier than the arrival time."

Pros: "Excellent Customer Service"

Cons: "No healthy snack options"

Pros: "Crew was cheery, in-flight entertainment innovation evident, plenty of opportunity for water/snacks"

Cons: "We were heckled by gate crew about whether my dog’s carrier was too small for him. Many suggestions were made that we were subjecting him to animal cruelty, and that we were abusive to him. He’s 7lbs, so he can’t be much smaller a dog, and his carrier it turns out, doesn’t fit under WestJet seats, despite being within carry-on luggage dimension limits (their life jackets take up most of the legroom), and thus could not be any bigger. Did they want me to have a smaller dog, or a Euclidean space-defying carrier? I suppose they were suggesting that taking a dog aboard WestJet is abusive, because they certainly don’t provide adequate space for anything larger than a hamster, they hassle you about it, and they charge you $50 for the fun of it. One agent had the nerve to reach into his carrier without permission, unannounced, and invade his personal space, him being a rescue and very anxious."

Cons: "To be honest, our stuartess was very abrasive. To everyone."

Pros: "Most things"

Pros: "Staff"

Pros: "The friendliest crew ever!"

Pros: "Liked most but don't understand why a family of 3 was separated. Bought tickets together."

Cons: "Could have ended our trip together but we were separated"

I made it to gate right before they closed the gates and still got put on the next available flight BUT let two other people go in who were behind me on the line. So disappointed.

Cons: "There are too many announcements on the screen before you can start watching entertainment. It takes about 15 minutes."

Pros: "Good crew and service"

Cons: "Tough landing at DC but it was the wind"

Cons: "Short flight, would have appreciated if when asking for pretzels the flaggt attendant didn't hand me the spare bag of his pockets."

Pros: "Really enjoy flying first class."

Cons: "Excellent"

Pros: "The crew was amazing, and the duration of flight time was reasonable"

Cons: "Comfort of the seat, space between seats"

Pros: "Good entertainment choices."

Cons: "Uncomfortable seat with insufficient legroom wouldn't recline. Inadequate overhead storage (full flight)"

Cons: "The seat went back three inches. I was about to spasm after 4 hours. No movement whatsoever. The flight crew could have moved me but I suppose they were told not to as I had a cheap ticket."

Cons: "Food quality"

Pros: "It was standard AA service"

Cons: "After flying in Delta Comfort+, American’s forward economy section is just nothing."

Pros: "Crew was tight, friendly, flight comfortable & painless."

Pros: "No amazing crew, just average. The should airline should have follow through on a specific request, but the airline's computer wipes out such things."

Cons: "Airlines should listen to the requests of the passengers."

Cons: "Sat waiting for gate for 30 min"

Pros: "On time,"

Cons: "WiFi didn't work."

Cons: "There was literally no entertainment for over three hour flight and our flight was delayed an hour while we were on the plane."

Pros: "The crew was polite and professional"

Cons: "At Miami check in, American had 40-60 automated terminals available for self check, but only had EIGHT open for use. Caused a needless bottleneck and the transition from there to the bag drop was also poorly laid out and did not provide a logical nor efficient route from one to the other. fix it!"

Pros: "On time flight. We were even a little early."

Cons: "Those seats are just crammed in there aren’t they?"

Cons: "The wifi signup process not seemless with Android."

Pros: "Crew was great"

Cons: "Absolutely no accommodation for seat assignments and the lady at the gate was so rude for even just asking to sit next to my fiancé even though there were tons of single people on the flight."

Pros: "The flight itself was fine."

Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."

Pros: "Even thou flight was delayed we arrive at a decent time."

Cons: "Flight delayed by 2 hours due mechanical issue Missed connecting flight Waited in line for 2 hours for a hotel comp. had to pay 20$ to get to hotel because there was no shuttle Still stuck in Dallas. Never made it to Sam fran. Extremely disappointed I expect compensation"

Pros: "Crew was good, flight was on time"

Cons: "Old plane, no TVs"

Pros: "Crew was nice"

Cons: "Not enough leg room. They did a gate change and I almost missed the flight because nothing was announced and when I looked at my phone app it had the previous gate."

Cons: "Flight was delayed so had to drive to connecting city just to make it home."

Cons: "Flight arrived over 40 min late and despite my connecting flight still being connected to the gate I was told I couldn’t board. There were 5 people trying to connect to the same flight so it’s pretty rediculous that we were told to rebook when the plane didn’t leave the gate for 15 more minutes. This was the call of the airline and it was handled poorly. The rebooking agent was also extremely rude and seemed totally self absorbed. This was my worst flying experience out of approximately 50 flights this year. Never again American."

Cons: "My bags were not checked all the way to my destination, I had to get them re-tagged and checked for this part of the trip and the American Agent was EXTREMELY rude and made us pay oversized bagge fees even though our baggage was within the Qantas allowance, the main carrier for our flight."

Pros: "The plane looks like new. Great seats, phone and tablet holders at the seat back, USB outlet and a smooth flight."

Cons: "The WiFi did not work and so no entertainment for a flight of almost 4 hours."

Pros: "Friendly crew"

Cons: "Tight seating leg room non existent."

Pros: "Landing and deplaning"

Cons: "Literally everything else"

Pros: "Our plane was given to another group going to Orlando so we were delayed almost 4 hours. This after a 5 hour layover."

Cons: "Gate lady was funny about being pissed about the delay."

Pros: "Great service in first class"

Cons: "N/A"

Pros: "Movie and tv selection was good. Boarding was a cinch, we took off exactly on time, seats were comfortable, too."

Cons: "Airline misplaced my boyfriend's checked back with our duty free Portuguese wine in it. It still hasn't been delivered to him the next day. They had three hours to get the bag on the flight."

Cons: "Flight crew was late and didn’t try and make things move faster to make up time. Kept saying they wanted to go Puerto Rico and that’s where they should have been going."

Cons: "Flight was delayed by 90 minutes because the incflight mint flight was late"

Pros: "Crew was great!"

Cons: "Was really poor choice of food."

Cons: "3rd flight in two weeks suck sitting next to a morbidly obese person. They should be forced to purchase two seats."

Cons: "the drink service came through pretty late in the flight. i asked for hot tea. a few minutes later i was provided with extremely hot tea. about 10 minutes later it was a temperature i could tolerate drinking. about 1/3 through the drink i was required to throw away my drink because we were preparing for landing. i understand that, fine. bad timing. it’s just a drink. what was unsatisfactory is that the attendant rudely commented “you have to give us your drink. it’s not that long of a flight.” the comment made me feel like i had done something wrong even though i had just been drinking my tea as soon as it was at a drinkable temperature. i was not impressed with the attendant. also, there weren’t any biscotti cookies."

Pros: "The first leg had awesome pasta.Then, on the 2nd leg, Philly to Denver, they had a "pay for meal" option for turkey with Chutney sandwich - again, delicious. I should add that the service was very good as well."

Pros: "Staff was great!"

Cons: "Seats were really uncomfortable up and reclined. Overhead baggage was full by the time I boarded and there was no enforcement of the carry-on baggage sizes... This needs to be addressed and contributed to our lack of comfort, noting this was the last leg of an 18 hour journey. My body still hurts today after a good nights sleep."

Pros: "We missed this flight."

Cons: "Background info: we flew from Dublin to Toronto (Aer Lingus) and we were supposed to fly Toronto to Los Angeles on American Airlines; however, we had a British Airways flight number for both of these flights. We missed our connecting flight in Toronto with American Airlines (we had a 2 hour layover) despite landing on-time (de-boarded a few minutes late). I suggest avoiding the Toronto airport ALWAYS as every passenger must pick up his/her luggage even if you have a connecting flight, and then re-check the baggage with the next flight. Apparently the baggage handlers were on strike and some of the customs agents as well which added to the delays. Well, after going through Canadian customs and picking up our luggage (which took quite awhile) we arrived at the American Airlines ticketing kiosk about 45 minutes before our flight. The computer told us we were too late for this flight and to see a representative. We proceeded to wait in line for an American Airlines representative only to be told this was Aer Lingus' fault (we had just flown with them); even though we had a BA flight number.. After searching for an Aer Lingus representative we were finally told they were probably all on the Aer Lingus flight that was currently about to leave. An Aer Lingus representative was paged to the ticketing counter (took well over 30 minutes for anyone to show up) and what proceeded was an argument (for well over an hour) between British Airways and Aer Lingus representatives about whose responsibility it was to re-book us. After an hour at least of poor customer service, we were finally rebooked by British Airways on the last flight to LAX (on Air Canada). Moral of the story: avoid Toronto and fly direct."

Pros: "I liked having a window seat."

Cons: "My screen was broken, so for 6 1/2 hours, I was unable to watch any movies and didn't see the safety video either."

Pros: "No excuse on a night flight does the temperature to be 80 plus degrees on the plane."

Cons: "The plastic seats and extreme temperature was brutal. They shut the AC off of down somehow."

Pros: "The check in process with the kiosks. It was very easy."

Cons: "They ran out of sandwiches that we had to pay for. We didn't have to do that on the Aer Lingus flight, which was for the same amount of time. In the other flight we had choice in entetainment."

Pros: "Entertainment."

Cons: "We sat on the runway for 3.5 hours while the crew cleaned up a fuel spill and we waited for a different co-pilot."

Pros: "I fly this route with American pretty often. The cabin crew was good. Everything else seemed sub par."

Cons: "Our take off was delayed, officially due to fueling the plane, but if the plane wasn't fueled ahead of time, someone failed to do their job properly. Also, while I'm starting to think that A320s just suck mechanically for landing (they always seem to land harder than a 737), this one seemed a little extra rough."

Cons: "Unexplained delay in leaving but only arrived about 10 min later than scheduled. Took an hour from pulling into the gate for bags to arrive though which caused me to miss my shuttle. Never had to wait more than 15 min for any other airline at DIA."

Cons: "They did not check the toilets before we left so we were diverted to St. Louis and I arrived in charlotte 3 hours late"

Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."

Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."

Cons: "When your on your honeymoon it sure would be nice to have a seat next to my husband like we requested."

Cons: "I was made to pay for my carry on because of weight. I didn’t understand that when I booked. I am also certain that many other carry ones were more than 12 kilos."

Pros: "Better staff than normally, which was both surprising and pleasant. Flight made it on time for the changeover in Zurich, which is very important."

Cons: "Extra charge for luggage - it showed up in the itinerary only after everything has been paid for. And even the paid suitcase allowed 23 kg only. It has been just over TEN years ago that you had two suitcases at 32 kg each included in price! Does the airline seriously believe that you can travel around the world with just a swim trunk in your pocket? This policy is an insult to any world traveller. We do not all go into an all-inclusive resort! The only drink offered during the flight was plain water, again a step down from before where they also offered others, e.g. orange juice. Seating - now that big persons have the right for two seats for the price of one, when will the same rational apply to tall people?"

Pros: "They got me home"

Cons: "Flight was delayed 2-3 times with no explanation. The food in the gate was trash . After boarding we waited on board for over a hour before take off , during which time someone was duct taping the inside of the plane together and I sat on a broken seat . The single flight attendant refused to take trash from people who didn’t finish their beverage . While the plane was reversing there was a huge bang and the plane shook as if we hit something . I observed gate agent repeatedly tell customers that she couldn’t help them find out if their flight was delayed and to just look at the computer board ."

Cons: "Air Canada Check In staff were extremely rude and unhelpful. My flight was at 7pm and I arrived at 6:10pm because I got stuck in traffic. I had already checked in online, all I needed was to get my baggage tags and drop my bag off. Instead of telling me where to print out my tag, they made me stand in line to talk to the check in staff at the counter. By the time I got to the counter, it was 7:40 and there was zero chance of my bag being checked in for this flight with the staff showing me attitude. When I told him that all I was here before the drop-off time and all I wanted were tags and that his other staff just told me to line up without helping, he just said "you can buy another ticket for the next flight or leave your bag here and pick it up when you return from your trip." Honestly, the worst customer experience I have ever had!"

Cons: "Put on Turkish air landed 12 hrs late lggage still missing"

Pros: "The extra $50 seats were roomy."

Cons: "Flight was delayed and no one knew why!... Plane had been sitting ready at the airport for hours. Novice flight attendants, they each picked on different things others missed just before them. No consistency, seats left reclined during takeoff and landing for example. One way there was drink service once even though it was a smooth flight and the return had drink service twice even though it was bumpier! Entertainment does NOT work on androids, it is NOT the AirCanada app they tell you to download prior to the flight, it's an AirCanadaRouge.pk file that needs to be downloaded in flight! Which means we're stuck paying for the iPad and of course only with cc because there's no wifi for debit cards.... AC needs to stop this insanely mediocre and yet expensive monopoly."

Cons: "we took off 3 hours after our actual take off time due to the cargo door not closing. we sat on the plane and they kept the exit door open causing very cold air in the plane. the door should have been closed to keep the heat in. for the 3 hours we were not given or even asked whether we might want coffee or something to drink or some kind of snack, they gave the business class something tho."

Cons: "Late flight the crew did.t care and many people missed connections. The customer service at the airport desk was understaffed slow and rude. They we're not helpful in trying to get new flights booked and I felt like it was asking a huge favor even though it was Thier delayed flight that made me miss my connection."

Cons: "Why no food or snacks?"

Pros: "No food, an hour late"

Pros: "Ease of service and efficiency."

Pros: "everything"

Cons: "few movies"

Cons: "No free snacks"

Pros: "The gate agents were polite and the boarding was relatively smooth. Food was fine and flight attendants were Excellent!!!"

Cons: "First point of contact was incredibly rude. First she told me she couldn't find my reservation. Once she did, she gave me a lecture about my married name. Next she refused to let me take my carry on bag saying it was too large even though it fit on all flights to Montreal. Once I proved it would fit with the luggage sizer she had moved on to another customer and ignored me for 10 minutes while I stood there even though my boarding passes were printed. When I got to the flight, I found it could have been gate checked but there was no need as the flight was NOT FULL and my bag fit with no problem at all in the overhead bins. In 35 years of flying this was the worst experience I've ever had."

Cons: "Very cramped like sardine tin. Not enough flight info boards in airport and they were hard to read m"

Cons: "Air Canada is always late in my experience. I always end up waiting at the gate for the inbound flight which happens to be late. It is so annoyingly dishonest, considering that the flight is announced as on-time up until minutes before the departure time. When all along they know the incoming flight is late. After we boarded the plane at origin, we spent 15 minutes at the gate and quite a bit on the runway. When nearing the DCA, the plane took a complete detour went near Baltimore and then Annapolis and then flew back to near Gaithersburg as if it was intentionally wasting time on the air. Upon landing in DCA we had to wait 15 minutes on the taxiway waiting for the gate to clear. The (one hour long) flight that was scheduled to land at 10:20pm landed just before midnight. Air Canada is awful. This happens every time I fly with Air Canada and their conduct is just cheap and dishonest."

Pros: "Excellent value for Economy flight"

Pros: "Comfortable flight, very pleasant cabin crew."

Cons: "No flight entertainment at all."

Pros: "It was OK but it had to be better than the flight to Canada which was delayed 24 hours (just for bad measure). It's a cheap flight and AC warn that the "in seat" screen is no longer provided so criticism on this basis is a bit silly. I noted that the free iPads in Premium Economy provided more films but they were so dated!!! Food in PE was much better as was the general service. It cost quite a bit in the "Auction" but it was worth it I think."

Cons: "This relates to the outward trip when we only found out at the check-in that the plane was postponed to the following day. OK, we were put up in a hotel for the night but 24 hours there was not the best day of my life. I wasn't too impressed with the hotel."

Pros: "on time, friendly staff"

Cons: "never on time, late flying both way's"

Pros: "Their sympathy for our atrocious wait was, free pop and water, and some pretzels. $30 meal vouchers at the limited options gate area, which could only be used towards a meal (really? no where else?). Here's a were sorry email and a discount on your next flight with us. I have yet to see how much the significant cost for that discount but my expectations of Air Canada are very low."

Cons: "That delay was horrendous, I spent 10 hours at an airport. I woke up so god damn early to get there because of news spreading the worries of people waiting at customs immigration to the U.S. it only took us 40min to get through and the flight delay notice was given an hour and a half before departure. We couldn't even sleep on any benches because they were all designed for individuals to sit. It wasn't until our gate location moved to the end of that area was there any carpeted floor space to sleep on. On the flight, economy seating was very tight with limited leg room, and best of all our seats had no window, literally every other row in our section had a window. Air Canada handled this stressful event very poorly, once they figured out bringing a new air craft hours later, and everyone moved to the new gate area, all the attendants had left from their gate post until 40min before the flight which was hours later."

Cons: "Headphone socket broken on this older airplane. Only purchased food available so n/a."

Pros: "Confortable"

Cons: "N/A"

Pros: "The flight attendants were very professional and accommodating."

Cons: "Our flight was delayed 2 1/2 hours at Narita and then again in Toronto for another 2 hours. Plus my family and I were tired from the 11 1/2 hour flight and when we get to check in the attendants were very rude, almost like it was a bother to them when we asked for help, it was probably because I interrupted their conversation. Every airports kiosks are different and that was our first time going through there so we just wanted to make sure that we did it right. Then when we get to the gate where we're suppose to leave out from, I asl the attendant there who I can talk to about forgotten bag on board. She then goes to tell me that I need to call the 800 #, Abd I said but I'm here at the airport can't they just bring it to this gate and she then got an attitude and said that they couldn't do that and I would just have to go to the lost and found which was downstairs. I was on the line with lost and found before I went to ask her any questions, and I mentioned to her that I had been on hold for 30 minutes, and she said they weren't going to answer. So I then asked hire am I suppose to get my bag then? She repeated about calling the 800 #, and at this time a lady runs up the counter thinking that she missed her flight. She shows the attendant her phone and is hysterical thinking that she missed her flight and the flight attendant told her just go sit down it's not here yet you didn't miss it. The customer then starts yelling in another language and the flight attendant just tells your just go sit down calm down and go sit down. She's doing all of this while I'm standing there she pulls out her phone and then told her co-worker I should put her on YouTube the way they do us. All the while I'm standing there because I still have more questions and she just ignored me like I wasn't even standing there. I more than likely will never fly this airline again, I'm paying for their services and to get treated like this, no thanks!!"

Pros: "At fisrt the flight was over booked. Once we had boarded their was a technical issues with the aircraft, we had to sit in our aiys with nothing to do for just under 2 hours. With this delay in mind their was no form of a free drink as a mini compensation. They had no choice of food."

Cons: "The time that I need to wait for my connections....I was traveling by myself with my two daughters 6 and 2 years old. And been honest wast pretty hard. Also, nobody told me about the permit that I need to have to go to Canada. I did the process online at the airport. Was fast but pretty stressful."

Pros: "This was my first time in Canada never been there before I had a great time until that one moment I had to deal with workers from air Canada except one agent at the ticketing desk....I had checked in online the day before however I had some card issues because they got shut down by my bank and due to the holiday in America I was unable to call my Bank prior to the airport....got to the airport and tried to explain that all I wanted to do was pay for my bag with cash ...but no one took the time out to listen each time i tried explaining myself I was send to a different location to join another line ....by the time I got to someone who was willing to listen my flight was closed ..her name was Aurora and gave me nothing but attitude when I explained my story......anyways finally got to ticketing and a met the only agent that day who exercise some level of customer service that day...if only I could remember her name ...sigh she went the extra mile because at this point I was frustrated and unsure if I would make it out of the country a sane person due to the amount of chaos I experienced prior. She got LISTENED .....SHE TOOK THE TIME TO LISTEN...got me on a new flight and went above an beyond to assist me that morning I was on the verge of a breakdown at that point all other staff member was very disgusting not only to my self but the other individuals who had mishaps that morning."

Cons: "Our flight was cancelled after already waiting through a 3.5 hour delay. The inbound flight was delayed due to weather, and as a result, there was no crew available for our flight. This left us stranded at Pearson at 3am with no Air Canada agents available for assistance. After a two hour wait on hold with Air Canada customer service, we were told the earliest flight we could get on was two days later. Unacceptable. We ended up having to buy tickets with WestJet. Weather delays are understandable. Not having sufficient customer service agents available for assistance nor having enough crew on call is inexcusable and incompetent."

Pros: "The crew was friendly."

Cons: "The plane was old and looked like it was going to fall apart. My seat was torn and the back of the seat in front of me was broken. Not my favorite airline by far."

Cons: "The crew waited so long to start selling food. Then, by the time the cart got to where I was sitting (only halfway back) they were already sold out of the two things I wanted to buy. The tea they served was the dregs from the bottom of the kettle, nasty and bitter. There was no "entertainment," except a crew member renting out a couple of ipads that connected to the wifi. The luggage compartments are oddly shaped so that you can only put your luggage in the long way. It a misuse of space. A lot of people had a hard time finding any place to put their bags. During takeoff, one of the luggage compartments opened up twice."

Pros: "No complaints about the flight attendants"

Cons: "Seating very tight and uncomfortable. Luggage handling is the worst I have ever seen. Out of 6 in our group, 2 had lost luggage and 2 had misplaced luggage. Airport customer service didn't care if items were lost or misplaced. Very unprofessional all the way around!"

Pros: "Everything was good."

Cons: "No issues"

Pros: "Entertainment"

Cons: "Crew was rude and poor communicators."

Pros: "good fast flight with great flight crew"

Cons: "food was mediocre"

Pros: "The flight itself was fine, free WiFi on board, movies to watch, stewards and stewardesses on board were very kind and attentive."

Cons: "I was originally flying WestJet, and the 7:05 AM flight I booked was cancelled. I hopped online and booked the 8:10 AM flight via Air Canada back to Boston. First, the flight was oversold, so only AFTER I was able to check my bag did I learn that I was flying stand-by. Completely nerve wracking. If I had known in advance I would have booked with another airline. I was able to get on the flight thanks to some volunteers who gave up their seats on the 8:10 AM flight for the next flight out (10:10 AM) in return for some monetary compensation. I arrived in Boston, and after waiting for 45 minutes, I learned my bag was put on the 10:10 AM flight rather than the 10:10 AM flight, but only after dealing with a snappy and disrespectful check-in attendant that seemed to not believe me that my bags indeed did not arrive. The office for baggage services for Air Canada was vacant and locked next to the carousel. Myself and a couple of other travelers, upon getting to the check-in counter and explaining the situation mistakenly lumped us all together and said "okay so you're all traveling together and your bags need to go the same place". Me: "No, that's incorrect, we are not related or traveling together, we just all have the same issue--none of our bags have arrived". Other Air Canada representative, who up to this point had not been involved in the exchange: "She didn't ask you if you were related, she asked you if your bags were lost" and then proceeded to roll her eyes and walk away from the counter. I suppose she misinterpreted my concern for rudeness and felt the need to put me in my place. Granted, my early morning flight cancellation and the stress associated with flying standby had nothing to do with them, but the attitude I was given as a concerned traveler whose bag was potentially lost was completely unwarranted. Compounded with the frustration of the entire morning I cannot describe how infuriating this exchange added up to being. I was told my bag would be delivered to my home by 4 PM that day. No bag. Got a phone call at 7 PM - they'd be there in the next hour. 10:00 PM and going to bed: No bag. I gave up and prepared to make a claim in the morning. 8:30 AM Sunday morning - my bag is sitting on my front porch wrapped in a trash bag. What a fiasco."

Pros: "Prompt and courteous. The Embraer was not new, but in good shape. Entertainment was minimal - especially in comparison to the Dreamliner we flew from Europe to Toronto. The flight from Toronto to Denver was about 4 hours long, but the only included refreshments offered were sodas, water, or juice. Air Canada could do better on the food front. (Other food was available for purchase.)"

Pros: "One person assisting passengers whose flights had been canceled was gracious and skillful."

Cons: "My flight, 370 was canceled. Initially, one of the AC staff at customer service was overwhelmed and impatient. The next flight was delayed by about seven hours. My baggage didn't arrive in Toronto. I found it extremely difficult to learn where the baggage could be, spent hours on hold with Air Canada and then Dynamex, and waited four days to receive my bag. I was with about 100 people at a summer camp. The staff created a funny skit about AC, Dynamex (sp?) and the endless "your call is important to us" tape recording. I understand that flight plans must be canceled and changed due to weather, but AC relies too heavily on automated "service.""

Pros: "Again, the entertainment options were the best part of the flight."

Cons: "It was a short flight, but it was still very cold. I didn't ask for any changes because of my previous experience, so I just wrapped up as well as I could and bore the chilliness. The crew was less than friendly."

Cons: "Our inbound flight was two hours late. When connecting through Toronto, they lied to us. They said that the outbound connection was on time, that we'd likely missed it. Then, after standing through their requisite customer service line with only one open desk for two full flights, we were told to sprint through customs. We arrived, breathless to find the connection was delayed. We were told that they don't post the delayed connections for fear that passengers won't run or that U.S. customs will close. Uncommunicative and untruthful, their service is atrocious."

Pros: "Size of plane allowing for aisle seating."

Cons: "Delay with boarding for about hour without a good explanation. All monitors in airport shows plane on time when it actually was not. Boarding process also took a bit of time perhaps due to many elderly on the flight. Seating was also confusing as the middle seats did not correspond with aisle seating. This caused delays as passengers had to figure out where they were sitting. Checked in luggage at gate since flight was full and we were asked to volunteer to check-in luggage. At baggage claim, bag delay to retrieve luggage after already hour delay in departure. Bags was not labeled or categorized correctly causing an extra half hour delay to claim bags."

Pros: "The on-board and Abbotsford-based crew acknowledged that we had all had a very long day. All thanked us for our patience."

Cons: "We were informed when we arrived at the gate that the flight was to be delayed by 8 hours because of mechanical problems. 8 hours! No offer was made to book us on a different flight. No one, at anyplace along the line actually apologized for asking us to wait around for 8+ hours when the flight was delayed. We did not even know what the mechanical problem was. When we finally were able to board the flight, the captain made a personal appearance in front of the cabin to tell us that he and his crew had been called at home to fly a broken plane. He briefly explained that there were no available planes to swap out and the repair required all day. Inexcusable! Our treatment did not measure up to the Canadian tradition of courtesy and politeness."

Pros: "The crew was great"

Cons: "The gate changed 4 times and there was confusion at final boarding. The Toronto airport TSA agents have absolutely no manners and need to be retrained or fired. Traveling has become very stressful and try make it worse. There was a Hispanic girl, heavy set with curly hair yelling at us to approach the scanners. I talked to her asking her to be gentle with us because we'd just flown for 7 hours and are suffering from time zone changes. Another yelled at my seatmate about his travel size after shave. She was a black Caribbean. She snapped at me about the importance of security and that he was rude for saying he didn't care that she'd throw his stuff away. I told her that he said he didn't care because he's tired and quite frankly, a trail sized aftershave that she doesn't approve actually doesn't matter and is nothing for her to get worked up about. Her colleagues were all staring at her as she started throwing her weight around and making unprofessional nonverbal noises. Then there the room where you weight for your name on the screen to appear if your number is 1 or 2. The people in there are extremely gruff. There was only one Hispanic woman who took my slip of paper that had my pic who said please and thank you. Then when you go to customs to get your passport signed, the guy at counter 10 starts arguing with me for no reason. I put 1 family member on the customs form. He asked if anyone is traveling with me. I said no. He clarified that one should mean an additional person and not just me traveling. I said it wasn't clear and I didn't know. But he decided to get argumentative with me about it until I said ok and walked away. Your TSA process is a nightmare. I did not experience that at Heathrow, Vienna, Or Tel Aviv (all places that have recently experienced terrorism). I didn't even experience it in my arrival town Denver. Toronto TSA is very very poor."

Pros: "We arrived nearly on time."

Cons: "They changed our gate three times and boarding was inefficient (it took them almost an hour to load a small plane) and led to a late takeoff. The customs process was ridiculous. Crew did not seem to care. No food was provided on a 6 hour flight that boarded at 6pm. Most people would not have thought that they needed to eat dinner before the flight. You had the option of purchasing snacks. The people in the rear of the plan did not receive the honor of buying snacks (or even getting a cup of water) until 3 or 4 hours into the flight. Uncomfortable seats. Avoid Air Canada until they get their act together or they lower their prices to reflect their new status as a discount airline."

Cons: "I didn't like that there were no screens to watch and I didn't know I needed the app on my phone to watch movies until I was already in e plane and too late download it."

Pros: "Got on flight"

Cons: "Got boarding pass but no signs to differentiate Air Canada counters (US-bound, domestic, international). Went to wrong counter and had to run to right one Booked flight. When I checked bag, I got a standby with hope that I could get on flight. Fortunately, I was able to make it. If I had connecting flights, it would have been a nightmare Same boring old movies and TV - 2 broke girls episodes. Just drink, nothing else for morning flight. Something to eat? It is an international (Can-US) flight Slow unloading of luggage"

Pros: "That I eventually got to Denver"

Cons: "Poor planning no backup aircraft I knew status via apps before staff did"

Pros: "Their was a two hour delay, the planes cabin was at about 55-60 degrees and due to bumpy ride...service was delayed (obviously not the fault of anyone). Just overall, uncomfortable experience!"

Pros: "On time, courteous, great movie selection for the very long flight. Food was decent."

Pros: "Food was actually pretty good and the staff did reasonably well even though most of the customers were clearly unhappy."

Cons: "A majority of flights run by Air Canada to the US were delayed. If this had been due to weather, fine, but at least our delay was caused by mechanical malfunction. Our flight was delayed for 5 hours due to multiple different mechanical issues including that the bathroom would not function during the entire flight, the wing flap had issues and the door would not seal correctly. The flight immediately preceding ours to Minneapolis was also delayed by over 4 hours. Surprisingly the flight before that also had a bathroom malfunction that prevented customers from using the bathroom. If this was the exception we could understand, but looking at the history of our flight, it's only on time 23% of the time. The poor customer service people must hate their lives. Something needs to change."

Both flights were perfectly on time, orderly boarding

Cons: "Video entertainment did not work properly. Stewardess reset it but audio was totally garbled. I tried it with three different sets of earphones."

Pros: "Yes"

Pros: "Crew on both our flights were very nice and accommodating."

Pros: "United delays"

Pros: "Nothing"

Cons: "Arriving on time to make my connection!!!!!!"

Pros: "Plane wasn’t full, crew was great"

Cons: "They could have better food options for a 7 hours flight."

Pros: "Nice crew, good take off and landing"

Cons: "We were an hr late taking off."

Cons: "Crowded planes."

Pros: "Good leg room"

Cons: "Seats are narrow. Not much shoulder space"

Pros: "Not much to like. The flight was okay."

Cons: "Not having free Wi-Fi and sound on the entertainment.I We could have been offered complimentary snacks as well with the beverage."

Pros: "Nothing, worst experience I’ve ever had traveling. Up for nearly 2 days and with no help from the local airport staff."

Cons: "Everything, no customer service whatsoever"

Pros: "Everybody was wonderful. All the staff were friendly and the flight was great."

Cons: "I volunteered to gate check my instruments (which I NEVER do because it’s not my hobby, it’s my livelihood). When I did, I made very clear that I’ll ONLY do it if it’s handed to me at the gate when I arrive. It CANNOT go into baggage claim because it’s 2 $3000, left handed, vintage Paul McCartney basses packed in one bag. The gentleman assured me that I’d have it handed to me upon arrival. It isn’t designed to go through the rough handling of people I’ve never met or trusted. So I got to Denver and waited at the gate until someone told me, “oh no that’s gonna be down in baggage claim” Needless to say, I’m scared to death and I don’t even know where $6000 worth of instruments of mine, is right now. I wish people would communicate when they promise things."

Pros: "Seats were comfortable, we were in first class. United provided a good selection of recent movies."

Cons: "United stewardesses have little to no interest in their duties. Questions were clearly an annoyance to them. The leg of flight from Denver to Des Moines was very uncomfortable, seats much to tigh, no leg room. Gate staff in Denver were exceptional. United needs to revisit their time for loading. We preloaded, I had a broken leg, I was traveling with a special needs woman. We just reached our seats when other passengers were prodding us to sit so they could board no time to settle. Not impressed"

Pros: "Quick flight - happy crew - United rocks!"

Cons: "Toronto Airport needs to get their act together. This is twice now that there were two Star Alliance flights to Denver at roughly the same time - United and Air Canada - miles apart in the terminal. Yet only the Air Canada one was on the flight board. I. Er half the flight walked to F64 and then had to run to F97. Shoddy."

Cons: "Lost bags and every time I called to find out where they were I would get a different story. I was told it would be on the next flight for the next 5 flights."

Pros: "The flight attendants were so nice, and although our flight was delayed and hour and fifteen minutes and our layover was an hour and fifteen minutes, we were able to make our connection! Since our connection to Portland in Denver was the last flight of the night, they were able to hold it for us. This was wonderful because there weren’t many flights out that weren’t booked solid for the next day. The attendants on this flight were great about updating us with information for the connections and telling us when we would land in Denver."

Cons: "The plane was delayed over an hour for cleaning. It was frustrating to say the least."

Pros: "The flight was on time"

Cons: "This was a smaller plane (4 seats across). Knowing this, they didn't bring enough luggage carts, so they only brought some of the luggage to the baggage claim and didn't tell us this. 5-6 of us waited and waited and finally asked someone who told us that they had to go back to the plane to get the rest of the luggage. Those of us still waiting got to wait another half hour for our luggage. Talk all they want, United just can't seem to get it right. PS: those of us who had to wait were the ones who got to the San Antonio airport the earliest and thus our luggage was on the plane first."

Pros: "Toronto is a good place to Fly out. Much cheaper rates than small USA city like Rochester. Booked 1st class Tickets for about the same price coach. They have Customs to USA very well thought out."

Cons: "Very minor delay boarding, made up time in the air. Gate crew reassured that all connecting flights will be fine."

Cons: "Seats to small. But I am 6'3"" and my son traveling with me is 6'5"."

Pros: "The leg from Denver to vegas was awesome"

Cons: "The first leg didn't have any snacks and a cold continental breakfast. American and Delta's breakfast is much nicer. But worth the price for that portion of the leg."

Pros: "Nothing"

Cons: "The plane was freezing. I needed to put on socks--really wished I had packed wool ones. The seats were cramped and mine did not recline."

Pros: "free movies on the flight with the united app"

Cons: "The flight attendant was late delaying boarding 20 minutes. Once they started, people were lining up to board. This is a normal behavior however, there employee decided to stop boarding because she said people were crowding. she stop boarding for another 20 minutes. Now, this was a large flight and there wasn't enough room for everyone to stand off to the side. She was rude and there was no reason for this especially when the flight attendant was already late. The plane was delayed 45 minutes due to this"

Cons: "Plane from Toronto to Denver could have been a bit bigger / nicer for that long a trip."

Pros: "I was sat in an exit seat."

Cons: "The lady in the seat next to me was so overweight that I couldn't sit comfortably for the entire flight - I had to lean out and it hurt my back!"

Pros: "Nothing I won't be flying united again!"

Cons: "The lady at the gate when boarding was not friendly and was not willing to help us get seats together. I was traveling with my mother, husband and two infant children. And it was like pulling teeth to get any information out of her. She did not even tell us we could board early to get situated on plane! I also called earlier that morning and spoke with a man on he phone at united who told me he put us all in the same row. That was a lie bc when we checked in at the gate to get our seats the lady said no one was sitting next to each other! That lady was rude and short tempered! Awful experience will never fly again!!"

Cons: "The default on the browser defaulted to April 9 when I was actually booking the ticket for April 2. So I had to forfeit the $317 ticket. I use kayak a lot - can anything be down ?"

Pros: "Food was edible, nothing special"

Cons: "Boarding was very slow, as was cabin staff. Not very attentive. Made a big deal about letting passengers with connections off first, although we arrived. We waited, as requested. Finally got up,after realizing everyone in the 20'rows behind us was gone."

Cons: "3+ hour delay"

Cons: "Flight was delayed to 4 hours now I'm rushing all over to get to my connecting flights"

Pros: "Small airport, comfortable seating, polite crew"

Cons: "Snack wasn't my style"

Cons: "Unable to pre-check online. Unable to check at the check in machines--had to go up and check in at the counter, long wait because there was only one clerk. We were then given a ticket just to get through security and had to check in a second time when we get to the gate for seat assignment, which is ridiculous. Why couldn't that be done at the 1st check-in? The clerk told me she will call me when she has the seat assignment/ boarding ticket but she never did and I had to go back up to ask for them when it was getting close to boarding time. At the last moment minutes, volunteers could check in their carry on for free....It would have been nice (and less hassle) to have that option at the 1st check-in."

Pros: "Quick and easy boarding, friendly staff, On time/early to arrival"

Cons: "Not a lot of space for passengers- even someone small like me at 5'2 and 120 lbs. Flight was also a bit turbulent"

Pros: "Nothing"

Cons: "I'm usually a patient person, but my flight was supposed to leave at 525am and didn't leave until 730. This was the first flight in the morning. We boarded, waiting 30 minutes on the plane, they told us to get off because there were computer issues. Why wasn't that checked before everybody was boarded? Once we got on the plane we had to wait another 30 minutes for the crew to get someone's luggage from under the plane. Why wasn't that done while the computer was getting fixed? I didn't get to Denver until 1040am missed my flight and didn't get to get on my connection until 500pm. In the meantime I called to get on a different flight at 1, but the guy on the phone didn't actually book me a seat. The gate people weren't very nice."

Cons: "The flight attendants were disrespectful to not only me but to other passengers. They were not attentive! The plane was dirty."

Pros: "Boarding was very fast and efficient. Seats were as expected on an airplane. The flight was only 45 minutes so there was no entertainment or food to really be able to rate them on it."

Cons: "The one flight attendant spoke super fast so it was a little hard to hear her clearly."

Cons: "A la ahora de irnos hubo muchos contratiempo por el tiempo pero por el vuelo después que nos fuimos fue excelente"

Pros: "A very typical flight."

Cons: "No complaints."

Pros: "Very friendly and helpful staff."

Cons: "The fact that we had a connecting flight to minot from Denver. Arrived late to Denver because of weather, but my stroller that I had left on the jetway in Seattle was never put on the plane which I didn't know until I got to minot. I was going to wait for it in denver, but I would have missed my flight to minot had I waited 5 more minutes. We arrived to minot only to find out that our 3 suitcases, one stroller and 2 car seats were never in the flight. Awful! And my connecting flight was even delayed an extra 55 min so I don't quite know where my things are."

Pros: "Crew were fine."

Cons: "Seats are narrower and make for a lot of discomfort when stuck in the middle seat. I do not like other stranger's bodies touching mine. That is just wrong."

Pros: "The staff was very helpful"

Cons: "Turbulence was horrid. Had to re route the landing causing me to miss my connecting flight. united had no other options for 23 hours. Therefore I chose to return to my starting destination. I still had to spend the night at the airport, and missed a 10 hour day of work due to no other flight options. All I received was a verbal apology. Glad I paid for a flight to a one night stay at Denver airport and back."

Cons: "One strange thing happened on my United airlines flight. The crew announced before we boarded that there wasn't enough overhead space for rolling bags and encouraged us to check them in. Upon boarding they announced that all overhead space in the back was full. I sat in the back and noticed that the crew closed the overhead compartments even though they were mostly empty. Another passenger opened an empty one and the crew came over and closed it right away, though many people were still boarding. What's going on?"

Cons: "The airplane was freezing, and I'm 23 years old and very used to flying."

Cons: "Additional fees for extra space were 1/3 the cost of my flight"

Cons: "My flight was scheduled to leave at 4:51 pm. I arrived at the airport 2 and a half hours before my flight was to leave and I read the departure board to see that the flight was delayed due to maintenance. Then I saw that it was delayed again because we were waiting for a flight coming in from the Bahamas. Well my flight didn't take off until about 7:30 pm. I arrived in Denver around 10:00 pm which made me miss my shuttle to the Springs. I am a diabetic and was in need of my medication so I needed to get home. I spent extra money to take a bus to downtown Denver and a grayhound bus to the springs and a cab to my home. So my trip cost my an extra $55.00 dollars I didn't have. I have always taken United but after this experience, I will never again take United."

Pros: "The crew is AMAZING!!! Personal, professionals, they go above and beyond my personal standard of customer service. Very comfortable atmosphere. Not to be mistaken with the uncomfortable seats. I like to think United doesn't overlook the work ethic their employees represent the company with on a day to day basis."

Cons: "I travel for work from Grand Junction, Colorado to Dickinson, North Dakota every 4 to 6 weeks. I always fly United. On one occasion I met family in Colorado Springs, so I bought a round trip ticket from Dickinson to Colorado Springs. I missed the second half of my round trip flight from Colorado Springs to Dickinson. I had to pay my own cab fare from Colorado Springs to Denver to catch my flight, because your plane, that i paid for a flight on, had mechanical issues and didn't make it to Colorado Springs. Second, my flight in Denver was cancelled 3 times and almost a fourth. I all but got down on my knees and begged to catch the fourth flight they tried to cancel. Third, I didn't even get to fly into Dickinson. So instead of somebody coming and picking me up in Dickinson which is a 30-minute drive from where I work, somebody had to drive 3 hours to Williston where you guys ended up getting me. Which cost me 3 hours of gas money to get picked up, instead of 30 min of gas money. I didn't get either of the flights back to North Dakota that I paid for. I've asked for the reasonable request that I be refunded 50% of the cost of the airfare and the $235 it cost for cab fare. When I contacted United about this I got the runaround from everybody. At this point I've pretty much accepted the loss, and the financial hit. I'll continue to fly United only because it's pretty much my only option. Just make sure you keep the crew around. They're great. I'd hate for the experience to go from unsatisfying, to miserable."

Pros: "they gave us the whole can to drink on the flight for drinks"

Cons: "the stupid old white man at baggage check in in New YOrk who was EXTREMELY rude and made me HATE flying with UNited"

Pros: "My flight started off with getting to the airport only to find my flight had been canceled in the morning and rescheduled at an earlier time while I was at work. I don't check my phone or email while at work. Fortunately, your staff was quickly able to put me on a flight that left an hour and a half after my original flight, but would put me on a connecting flight with American Airlines in Chicago. The AA flight had engine trouble so it turned around and we borded another plane after we landed. The original flight would have had me to my destination by 9:30 pm. Instead I arrived at 1:08 am the next day. I am frustrated that my flight was canceled so close to my departure. It was a great inconvenience to those picking me up at the airport. It added to my stress. It made it much less likely that I will fly United again. Maybe you had good reason to cancel my flight at such short notice, but it severely tainted my experience and opinion of United and American Airlines which had been fairly positive until now."

Cons: "The inconsideration for my schedule. The last minute change."

Pros: "Punctual flight, lack of major issues. Friendly staff helps on a long flight. Handled minor issues in the cabin well."

Cons: "Boarding the 747 was a bit disorganized, using doors on both sides of the gate desk led to confusion."

Pros: "Not only do I get the best price. The fact that you told me what carousel to get my bag from was new to me. I alway check kyak first but now I love u guys. I know my travel site and its kayak"
