Airline reviews

Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"

Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."

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: "In a pinch they were able t"

Pros: "Everything was perfect !! Staff friendly"

Pros: "Great in every way"

Pros: "Excellent piloting and cabin crew."

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"

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: "Love the inflight entertainment and the usb plug for phones. Flight left on time and go in a little early"
Cons: "Did not love getting charged $2 for headphones and the girl sitting next to me getting them for free. Super annoying"

Pros: "Nothing"
Cons: "Felt agents held me back at the check-in counter resulting in me missing my initial flight and voiding my complete routing. Had to fly on a flight 7hrs after my booked flight because Delta had no other option (very untrue as there were other airlines flying to my final destination. Delta just didn't bother providing good customer service"

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 entertainment unit allowed me to watch the Denver Broncos game live which helped lessen the delayed departure and uncomfortable seating."
Cons: "Uncomfortable seating....too crowded!! We had a delayed departure by 30-40 minutes because of a computer download issue. Too many folks carrying carry-ons delayed boarding. I wish folks were not encouraged to go that route but to check baggage. This time of year gets even tougher with folks carrying Christmas presents and over sized personal items. Ugh. Not fun to travel this time of year."

Pros: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."

Pros: "really helpful and friendly service and nice seats."

Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."

Pros: "free texting and entertainment!"
Cons: "our flight was delayed half an hour."

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."

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: "When deplaning in Denver, I was impressed that the captain was the staff who got behind my wheelchair and offered to push me up the walkway :)... New aircraft, kind staff, shorty flight!"
Cons: "Nothing disappointed, butt i didn't have any good besides pretzels."

Pros: "Not much to like here. The new crew was pleasant"
Cons: "Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines."

Cons: "Excellent service excellent pilot"

Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"

Pros: "Entertainment"
Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."

Pros: "I love the new snack choices! Way to go Delta for offering Kind bars now!! This is awesome."
Cons: "Tiny old plane, props blocked my window view, no entertainment system."

Pros: "The staff of the flight were very friendly and attentive. They were great!"

Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."

Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."

Cons: "long wait and delayed flight"

Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "Attendants and entertainment"
Cons: "Delays for no explained reason"

Pros: "One male attendant from the first class cabin - super sweet and attentive to our needs even tho we're not seating in the premium cabin"
Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"

Pros: "From the Ground crew to the Flight crew, you can feel the genuine care and thoughtfulness of everyone! They even remember you, if you fly often enough, and let you know how much they appreciate your business."

Pros: "Very professional and caring."

Pros: "plane had individual movies for free with each seat!"

Cons: "Flight was repeatedly delayed. Ended up being over 3 hours late to depart due to weather. Another delay due to mechanical problems."

Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."

Pros: "nice snack"

Cons: "We did not board at the scheduled time, although I believe we arrived on time. The crew was demeaning and singled out individuals who were causing the aircraft to not move. It was in a very pretentious manner, not like southwest personnel who have similar antics but with a playful tone. The plane is a small one where bags don't fit overhead and many head bumps occur. We arrived fine which mean the flight was successful but it was not very enjoyable."

Pros: "Westjet's employees were very pleasant and helpful."
Cons: "Delta told us we were flying out on a Delta flight, and gave us a Delta flight number. In reality it had placed us on a Westjet flight without telling us, and we had no idea we were to check in with a different airline. And because Delta unilaterally changed our flight time without telling Westjet, we were unable to check in online and were later told that we were booked on the wrong flight by Delta. Delta's communications with us and with Westjet were deplorable."

Pros: "Left on time, arrived early. Great cabin service, attentive and polite. Comfort Plus seats are worth the extra few bucks."
Cons: "Nothing. Low rating for entertainment only because there really wasn't any, but I wouldn't have used it anyway, so no big deal."

Pros: "All went as planned and expected. No thrill- like taking a Greyhound bus in the old days...gets you where you are going but without much pizzazz New seats and quite clean, but the new seats were very hard and uncomfortable after an hour."
Cons: "Somewhat claustrophobic and always wish the drop down tray table behind could be disconnected from my seat. When the passenger behind uses the tray as a set of bongo drums to keep beat with his headphones it is a pretty miserable trip."

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: "Good crew and on time departure"
Cons: "Overnight flight. How nice it would have been to have blanket and pillows as provided by some airlines ."

Pros: "Amazing crew. Very thankful my flight went smooth as I flew with my puppy."

Pros: "Our stewardess was amazing. Took very good care of us. My son was sick and made sure a wheelchair was available for him total take us to transportation. Made our trip. Thank you!!"
Cons: "All was good"

Cons: "Delays left us in the plane for almost 1 1/2 hours before leaving Toronto."

Pros: "Horrible check in"
Cons: "Rude staff"

Pros: "Need more leg room"

Pros: "Had seats in row six -- plus there was room for both our carry-ons!"
Cons: "Flight was delayed taking off from Winnipeg 90 minutes with no explanation given. Made us late getting to Saskatoon and missed our daughter's scheduled ride to pick up our two cars as a result. Had to pay an extra two hours parking at airport, etc etc etc."

Pros: "Joesph air host was amazing! Took care of numerous people with kindness & professionalism on our morning fright from Toronto to Vegas!"
Cons: "Lots of kids on the flight. Parents did a great job coupled with the staff. I very grateful! I needed a nap ! Iol"

Pros: "Westjet service is always the best. Flight was smooth and seemed very short. Again the crew makes it the best!"
Cons: "We were late cause of a thunderstorm but that is nobody's fault."

Pros: "The flight was on time."

Cons: "Tiny chairs"

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: "Excellent service and smooth flight!"

Pros: "So poorly organized at boarding ! Staff on the ground that where lazy ! On board staff where lazy ! Waiting for luggage took over 40 mins. Horrible ! Good thing I've had other flights that where much better."

Pros: "West Jet just runs a relaxed yet professional airline. They are just more laid back and accommodating. You can use any bathroom on the plane as well which is huge on those rare times you need to use it. They are funny and chatty and seem to enjoy working together which all translates to a less rushed and relaxed experience for us the passenger. I really can’t complain....I had an entire row to myself....the best you can hope for, when riding on a plain for hours that’s like winning the lottery!"
Cons: "No complaints for sure"

Cons: "I was in row 2 and they did not have the food item I wanted. Seriously?"

Pros: "West Jet never disappoints..."

Pros: "Extra leg room, staff very friendly and helpful."
Cons: "No tv screens on back of seats, liquids should be offered more"

Cons: "having to walk outside the plane in the snow to get on the bus and vise versa. it was cold and I got a bad cold...."

Pros: "THE YOUNG PERSON FROM GRAND PRAIRIE AB WHO SET NEXT TO ME WAS A GOOD TRAVEL COMPANION"
Cons: "THE SEATS WERE MUCH TOO SMALL FOR TWO MEN BOTH OVER 250 POUNDS TO SIT NEXT TO EACH OTHER"

Pros: "WestJet was great. I had assistance this flight and they took great care of me"
Cons: "Totally full flight so squished in my seat"

Cons: "We were told not to take the late flight to TO as Westjet would not hold the connecting flight (TO to Gatwick) for us. This meant our TUI connection in Gatwick to Chambery would have been wasted along with bus transfers. West jet did not offer us AC flights that were available to keep us near to our schedule. We ended up cancelling the Westjet flights and buying AC flights to Heathrow at a cost of $3300 + $300 taxi to gatwick + abandoned bus to Gatwick Westjet did offer us a flight on Sunday ! In the end, we are not sure if booking thru Kayak was part of the problem as Wesjet staff said ..... Oh you booked thru a 3rd party Comments ?"

Cons: "The entire flight's baggage never were received. The stewardess even promised that all bags would be received within 20 min. We waited 1 hour until we went to go talk to someone to inquire about the delay. They opened up a baggage claim, but the claim status only ever says open or closed, which says nothing about the status of the bag."

Cons: "Lack of attention from aeromexico in customs to ensure making the connection. Sevice is a joke."

Cons: "2 hour delay, small plane, rude crew"

Pros: "The reservation was quick and effective"

Pros: "Nothing"
Cons: "Our flight was delayed by 3 hours. We missed our connecting flight so we are in a hotel in Toronto now at 1:30 am. And our flight out is at 5:50 am and we will need to get up by 4 to get to the airport by 4:50. Getting our hotel and food vouchers was long and painful and disorganized. Would not fly with them again"

Pros: "Pretty quick boarding, although the boarding time was incorrectly mentioned to be too early."
Cons: "Had to de-ice so we left about 10 minutes later than expected, but somehow still arrived early… but our gate had another plane still using it. We ended up arriving at our gate 25 minutes late. That's unacceptable, especially on a flight that's just an hour long. The gate was so far from the public transportation (landed at Terminal 3, public transport is at Terminal 1) that I missed the bus - got home super late as a result."

Pros: "Crew was great"
Cons: "Who decided that seats should be shaped that way? Always gives me a backache."

Pros: "Cabin Crew were nice"
Cons: "Very tight seating."

Pros: "Lots of leg room and liked the screens for each seat even though I could not listen to what was playing on it."
Cons: "No headphones and the crew member I asked said he would ask at the back but never got back to me."

Pros: "Crew was fun and helpful. Was extremely accommodating in helping me switch to an earlier flight"

Pros: "Very helpful employees letting us know procedure of bosrding"
Cons: "All good"

Pros: "Personable and professional staff. Great service"

Pros: "Soft voice of flight attendants with such an early flight."
Cons: "Paying for food. Paying for luggage. Movies in a loop, not on demand. Missed beginnings of all movies I watched."

Pros: "Really great attendants. Friendly and humorous."
Cons: "They took the tablets pretty early it felt. 45 minutes before we landed. But other than that, great experience!"

Pros: "West Jet is just so much more professional than other airlines that you could select ! The attention to detail goes above & beyond to make each person feel welcome !"
Cons: "From check-in to the flight crew, West Jet is the best !"

Pros: "As usual, the gate and air crew were extremely helpful and efficient. I love that the flight attendants almost always have a great sense of humour. This helps put everyone at ease and in a good mood for take-off. The flight was right on time."
Cons: "We gate-checked our baggage on the first leg of the flight and didn't quite understand why we had to take it off and back on again for this flight when it was on the same plane. There wasn't much legroom; and when the rather thoughtless guy in front of me reclined his seat fully, I could barely move. Luckily, it was a short flight."

Pros: "Best WestJet flight ever!"
Cons: "No issues."

Pros: "Reaching my destination"
Cons: "Wish the emails/alerts came sooner. I waz always in transit when i was told my flights had been delayed or cancelled. I wont blame people for weather but it was the most annoying trip i have yet to take. I dont mind dissapointment but please dont waste my time."

Pros: "Excellent crew"
Cons: "No issue at all"

Pros: "same as above."
Cons: "same as above."

Pros: "Everything was okay"
Cons: "My boarding was no so good. However all went well."

Pros: "fair bit of leg room. fairly relaxing flight, as i am not a frequent flyer. good and safe landings as well as 'lift off' all staff was good on flight"

Pros: "safe flight comfortable seats but not much room"
Cons: "limited leg room"

Pros: "Clean plane, entertainment, crew...WINE! This has been my best flying experience in Economy for a long time. Good leg room."
Cons: "The checkin agents couldnt help me to merge two itineraries for easier transfer between two WestJet flights."

Cons: "Paid for reservation of a particular seat. At check-in was offered my choice of another seat without regard to the fact that I had paid for seat selection. Westjet employee did not honour paid-for selection or offer refund."

Pros: "The staff was very friendly."

Pros: "The flight was forced to leave a few minutes late due to Toronto air traffic, but the pilot let us all know what was happening and why, and the service staff were funny and gracious."
Cons: "I was on a turbo prop and the seats are a bit more narrow than regular planes, but thankfully I had no one next to me so I had enough room overall."

Pros: "Pleasent"

Cons: "3+ hour flight with no TV/ entertainment"

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: "Wonderful, again. Will fly American any chance I get!"

Pros: "The onboard entertainment selection was excellent; great movie selection, wifi connection, and flight details. A winner! So much so that I chose to binge watch movies and not sleep!!"

Pros: "Friendly crew. Due to the apparent regularity of excessively delayed American Airlines flights, they had the staff at O'hare bring a cart filled with cheap canned juice and Diet Soda to lessen the blow of their consistently delayed flights."
Cons: "Like every other American Airlines flight I've ever been on, it was delayed. Including the American flight from Denver to Chicago. We pay entirely too much money to these airlines for them to deliver such painfully mediocre service and consistently delayed flights. I recommend that this airline do a SERIOUS audit of their Preventative Maintenance/Service division across their hubs. If I fly American, I would bet my entire checking account that the plane will be delayed well over 2 hours."

Cons: "the new seats are awful"

Pros: "It’s been a while since I’ve flown American, but the aircraft was updated with a solid multimedia system, great moving map, and a standard power plug and USB port at every seat. That’s more than I expected, and was quite happy. Service was solid—no complaints."
Cons: "Good & bad — flight arrived late, but the honestly, the pilots did their level best to make up the time and managed to arrive w/in 4 minutes of the scheduled arrival. Well done."

Pros: "Crew was really understanding of the frustration and were helpful. Plane was clean and newer."
Cons: "Delayed due to weather... it happens. Just frustrating being delayed on the last flight of the day."

Pros: "Tv and power outlets"
Cons: "This one attendant didn't get her name but was very cold to me"

Cons: "Long delay"

Cons: "plane had mechanical problems - new plane and gate and an hour delay. - first drink should have been free"

Pros: "Confusion, delays, rude employees...you name it, this trip had it. I will do my best to avoid flying with these guys in the future."
Cons: "Flight delayed 15 hours. Poor communication and outright lies from staff. Unwillingness to help find or pay for a place to spend the night. Rude staff"

Cons: "Missed that flight because my finair was delayed at Helsinki"

Pros: "Crew"
Cons: "Small plane"

Cons: "Watched a very weird interaction between Muslim (with a hajib) women with a kiddo and desk crew. She wanted to sit next to her child on the flight and needed to switch seats to be able to. Woman was very gracious and understanding that she was asking for an accommodation. Ends up her flight to Philly had been moved to a different gate after they had found a volunteer to switch seats. Volunteer was totally unfazed but Desk crew made it seem as tho the Muslim mom was at fault for the time and trouble they had had to go through to accommodate her. She apologized profusely and was very appreciative for the trouble evernote had gone to for her. . As she walked away the crew looked at each other and shook their heads. Pretty crummy way to treat customers!"

Pros: "Good serice,"
Cons: "Good service to switch flight pattern from greenville to new bern but still a delay that cause a 2 flight connection. Lots of on-line issues with check-in, overall a stressful day, hopefully it will all work out!"

Cons: "I can't rate it because they canceled my entire itinerary without so much as an email. I did not take my flight to Wilmington via my original flight. I had to book another flight because the change fees were too expensive. I did not know that my return flight to Denver had been canceled until I was checking in a few hours before my flight. I was told my ticket had no value. Awesome! It really stings that I then had to book a new return flight, and because I am a teacher who makes about $23,000 a year, I had to book the cheapest flight, which was with American. I do not plan on giving them any of my hard-earned money in the future if I can help it."

Pros: "Everything"

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: "Flight was on time through United since we had to be rescheduled from our original flight with American."

Pros: "The plane was sleek and clean. I had a good amount of room even in coach!"

Pros: "Flight was good overall , free pretzels were tasty. Drink service on point."
Cons: "Crew came off as annoyed the whole time. Glad I didn't pay the $$ to upgrade my seat."

Pros: "The crew were as nice and accommodating as they could be considering the situation."
Cons: "Three planes with "maintenance" issues and not able to fly? Including flights that weren't ours. Boarding, re-boarding, leaving four hours late and waiting an hour for bags in Denver."

Pros: "The departure time. This left enough time to get to the airport and go through security without rushing!"
Cons: "Sitting in the middle Paying for luggage ( I wish Southwest flew out of ORD)"

Pros: "Crew"
Cons: "Had to board three times, two different planes. I understand mechanical problems, but 3 hours later, and on another plane, the captain starts making stuff up, saying that the only reason we hadn't moved in the last hour was because people were using the bathroom, then something about having to deplane because the plane couldn't back up with us on it because of some sensor? And then, surprise ! All of the sudden they noticed there was an issue with his and some of the crews' hours and we had to wait till they could locate more crew. But they gave us each a 1/3 glass of water and later a $12 food voucher which didn't even cover a meal and beverage. Whoop-de-do. 7 hours later we finally boarded for the third and last time. The crew on the other hand stayed professional and friendly."

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

Cons: "Seats too small and the gentleman next to me was a big guy so crowded over into my seat some."

Pros: "American Airlines is my favorite Airlines to fly. There is a little more leg room and the seats are a little wider. The staff is very professional and courteous."

Pros: "Very friendly staff"

Pros: "The plane was new on the interior and comfortable."

Cons: "The customer service from AA representitives in the airport was completely unnacceptable and the absolute worst service I have recieved in an airport to date! One incident during this trip was as follows: When arriving in Charlotte and running to catch my connecting flight, I arrived as the lady at the desk was closing the door, she looked at me and rolled her eyes. When I went up to the desk along with the other passengers arriving from the same flight as me the AA representative said "Hurry up , I want to go home!! At a point I'm just going to cut you off and that will be it!" She was of no help to me in anyway amd was forced tonstay the night in charlotte ; Normally this would not have been such a big deal, However I am on emergency leave from the Navy rushing home because I have a very serious family emergency, that representitive was very lucky I held my temper! From now on thanks to the poor unproffessional customer service I received I will no longer be flying American Airlines!"

Pros: "I liked sitting next to my friends."
Cons: "Lack of leg room"

Pros: "They showed American ninja warrior."
Cons: "Everything. The flight was delayed greatly even though the plane got to Chicago only slightly late. Then they make us board and just sit in the plane for an hour. Then finally we start moving, the plane is uncomfortably hot even with the air blowing on me, the flight attendants look like they hate their life, it was honestly horrible and I will never fly with American Airlines EVER again."

Cons: "The service was terrible, 4 hour traveling and not food."

Pros: "Had more leg room."
Cons: "The delay in the flight. The extended boarding process."

Pros: "the entertainment was good. Loved the free wifi. Loved the complimentary drinks"
Cons: "The flight took 45 mins to depart after the scheduled time. The flight attendance were super rude. The pilot was not easy on the landing or how he took off. First flight ive ever felt sick on."

Pros: "A free airline ticket!!"
Cons: "I did not like the fact that American Airlines cancelled my 17 Yr old neice's flight from Dallas to Denver over a thing called "timed-out". And had her sleep in a room with a cott instead of a hotel room. And the fact that we as customers pay good money for tickets only to be subject to the airlines way of business. It is absolutely unacceptable!"

Pros: "Very comfortable First seat on the E75. Lots of space."

Pros: "COMFORTABLE SEATS EVEN FIR A BIG GUY LIKE ME, FRIENDLY STAFF."
Cons: "LAST RED EYE FLIGHT WAS CANCELLED"

Cons: "Im still in dallas.....very angry"

Pros: "I fly alot! I have never been on a plane that was so shaky from take off. No wind nothing crazy effecting the pilot. It felt like maybe it was his first flight"

Pros: "On time and good price""
Cons: "Don't like the communist inflight movie choice shown? Other option than pretzels for snack?"

Pros: "Flight delayed provided snack in terminal at gate."
Cons: "Flight delayed three hours"

Pros: "The flight staff was efficient boarding people and were pleasant despite the close quarters, full plane and bumpy turbulence."
Cons: "The boarding crew woman was completely and unnecessarily rude. I have a small purse I had gotten out of my backpack to get my boarding pass that she insisted I put back in my backpack before loading. I understand the concept and reason for the request but the manner in which she did it was so uncalled for. I don't recal a time in which I've been spoken to in that manner in a very long time. While I was doing it (it took literally 5 seconds), she was screaming at me to walk over to the side and lose my place in line. After I quickly put it in she screams it must go in all the way, which it was. There wasn't even a bulge from it and it closed with ease. I'd be happy to provide a picture of my small backpack/purse."

Cons: "I was dissappointed in the additional baggage fees for checked bags and then have to watch people fight for carry-on baggage space. Ridiculous situation airlines have created. Plus flight was delayed because of mechanical problems coming back. But in flight was comfortable and well done."

Pros: "Absolutely nothing about them. By far worst experience ever."
Cons: "The staff talked to me in a condescending voice. First flight I called the airlines and asked simple questions on what time we should be there and the process. Then we get there by said time and they said she missed her flight. Keep in mind I have a one hour each way drive to lax. Came the next day 3 hours early to stay in the line 3.5 hours and the line was short! They let people cut us left and right and the staff was rude on the phone and there. I lost ANOTHER work day dealing with them. They said she was on standby for next flight 3 hours later only to get to the gate and they said they NEVER EVEN PUT HER ON THE LIST. then she got put on the next flight 3 hours later to get told it was a full flight and so she waited another 3 hour flight and finally got on... on top of the stress I went through, the work I missed out on, the drive and gas it took to get there, her first day of her Job was the next day after that mayhem! It was absolute chaos. I can honestly say I hate that American airlines and I don't think it's right. The person next to us also had a horrible experience with them in the line next to us. She missed her best friends wedding due to three disorganization and horrible service.... SHE WAS SUPPOSED TO BE A BRIDESMAID!!! I wrote the company.... but I expect no return or respect from them if I can't even get that from their condescending customer service "manager" ABSOLUTE WORST EXPERIENCE EVER!!!!!"

Pros: "Professional, punctual good flight"
Cons: "Like on domestic flights limited service."

Cons: "Had to check my bag because they ran out of overhead bin space."

Pros: "New airbus 350-390 are worst than older planes. Economic class space is even smaller now, no storage space for the last few rows"
Cons: "Last 3-5 central rows in economy class have no space for carryons. On top of that, at arrival we realized they have lost our bagage, all 6, so we’re left with carryons. This may be our very last trip with Lufthansa."

Pros: "Quick flight. Dlient Service in check-in was excellent, she went the extra mile to change my return flight to a more reasonable time."

Pros: "The 777 is excellent. Service very friendly. Food is good. One leg flight is super good"
Cons: "Apparently the pilots are allowed to smoke on these long flights. In this trip it was not bad but on previous flights it was really bad"

Pros: "short pleasant experience"
Cons: "baggage check is always complicated .they make a big deal over small items"

Pros: "Great service from flight attendants. Flight was smooth once airborne"
Cons: "Delayed Flight Seats seemed very small for an Air Canada Plane"

Pros: "MIGHT give me a refund, and not WILL give me a refund"
Cons: "Service personnel at Air Canada were very helpful and re-booked me several times and when none of those flights left, they said they would refer me to refund department."

Pros: "Pilot apologized that the entertainment system was down. Then suggested we turn back 10 years and do it the old way by reading a book or magazine to pass the time."

Pros: "Staff were incredibly kind, courteous, and knowledgeable. I need wheelchair assistance and they handled that beautifully, asking thoughtful questions about my needs and adapting their plans to my answers. They also helped me with stowing my carry-on since I would have struggled alone."
Cons: "Unfortunately, through no fault of the flight crew or gate crew, we got one of the few remaining planes in the fleet that are so old that they can't fit a full carry-on bag in the overhead bins or under the seats. Larger carry-on items had to be checked through to final destination, which made a lot of passengers upset -- either because they were business people who needed to be able to work on the flight, or they had important baby gear in there that they would need before that, or they were traveling far away using multiple airlines and were rightly worried about lost luggage."

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."

Cons: "Minimal cabin service. Plane arrived late. Almost missed connection. Officious cabin attendant."

Pros: "The entertainment system was fine as far as selection goes."
Cons: "The stewardesses were slow in doling out beverages, so much so that they didn't even get half the plane. As well as I was told they don't do free snacks on the linger flights and this being a shorter flight and should have therefore given out pretzels or whatever."

Pros: "Air Canada personnel made sure I made the connecting flight from Paris to Denver through passport control and the repeated safety checks in Montreal. The small aircraft was spacious even in economy."
Cons: "A male flight attendant was unwelcoming when I finally got to the plane (being late was not my fault). Did not want to help looking for a spot for my normal size carry on. When I pointed out one above him, he left my bag there and just walked away. I am 69 years old, 5'1"."

Cons: "previous flight was late so we had to be rebooked. The line was insane with 3 agents. The 3rd said go to the other 2 lines. The second went on break leaving one agent. A manager came down and gave the sorry here is our corporate email speech to two girls in line but left without acknowledging all the rest of us waiting. It was a mess. When I got my ticket she was like here you go without explaining anything or a sorry. When I asked for a few details like am I in a hotel overnight or when do I leave she gave me an eye roll. When I got to the plane after traveling all day and waiting extra hours there was an empty row right in front of me. I tried to lay down but the attendant made me move because I hadn't booked comfort plus even though the flight I booked I would have been in Denver hours ago. Things happen but it's all how you deal with it and air canada does not deal well."

Pros: "Food was actually pretty decent tasting and priced."
Cons: "One of the female flight attendants was quite mean and just had a poor attitude. Glares, muttering under her breath at passengers etc. Overhead storage is just a nightmare! Always filled to the brim. I've heard flight attendants bashing passengers about it openly. Maybe if you didn't charge $25 per bag per leg people wouldn't do this. Something reasonable like 5-10$ would help this problem HUGE."

Cons: "Crew were very rude"

Pros: "Airlines keep the cabin too cold. On the domestic of the travel leg blankets were for additional pay which is crazy - I understand about meals, but blankets are required only because the conditions offered by the airline are uncomfortable. One luggage was lost, but that is now almost part of travel."

Pros: "Good on flight entertainment. On this flight we had a good crew and good staff. However it has been mixed in the past with air canada"
Cons: "No food or snack. Only drinks or food for purchase."

Pros: "The plane was very new. Had a great entertainment system. Power plug ins. USB plug ins. Seats were a bit small, but when are they not?"
Cons: "They forgot to bring me dinner then when I finally got someone's attention they told me they had given away ALL the dinners. How is that even possible? In the end they gave me a first class meal so not bad."

Pros: "Staff was courteous and friendly. Check-in was quick and painless, despite the mobile boarding pass not working properly."
Cons: "Did not ear food or use the in-flight entertainment. Seats are TINY! As a person with very broad shoulders, I found myself literally wedged into a corner as to not bump the person next to me. These planes should not be 3 seater when they are designed for two."

Cons: "Received my luggage after one day"

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: "Staff was at least friendly"
Cons: "For a 5+ hour flight only beverages were offered - anything else (such as a snack or small meal) had to be purchased. Very cheap service IMO. The selection of entertainment (movies/tv shows) was exceptionally limited and out of date. Their way of boarding the plane (via zone) is very backwards as families with children weren't asked to board until half way through the plane loading (unless those families had already paid for the more expensive zone upgrades). Most airlines let them load first to give them extra time. My checked bag was 1.2kg over the limit so I had to open the bag and switch 1.2kg of clothing into my carry on in front of the rest of those checking in. What an embarrassment and such foolery. All in all Westjet does a better job for trips across Canada. Will not be trying Air Canada again."

Pros: "The in flight entertainment was great!"

Pros: "Nothing"
Cons: "There was NO complementary food for a 5 hour flight. I didn't have a credit card to purchase anything"

Cons: "Squeezed in like sardines. Nickled and dimed at every turn."

Pros: "They our sits for a better one because of my 6 year old son."
Cons: "Nothing"

Cons: "Never made connecting flight due to delays on first leg of the trip. Airline was generally apathetic to situation."

Pros: "Everyone was nice and friendly,"
Cons: "They changed our gate 3 times, and delayed our flight an hour and a half. It was extremely irritating and time consuming."

Pros: "That I eventually got to Denver"
Cons: "Poor planning no backup aircraft I knew status via apps before staff did"

Pros: "Nothin"
Cons: "IFE and food were awful. Space was cramped, lights left on for a night flight. AirCanada headphone rules are just dumb."

Pros: "Nothing to like or not like. Classic small (Embraer) flight for 3 hours. Nothing special one way or the other."

Cons: "Got to Denver 4h Late."

Pros: "The plane didn't crash."
Cons: "We were dehydrated and the flight attendants were stingy with WATER."

Cons: "It was a short flight so everything was ok"

Pros: "Excellent customer service, offered plenty of water to drink, entertainment consoles worked on this flight. Suitcases didn't take long to be unloaded."

Pros: "Crew was courteous and efficient."

Pros: "Originally this flight was scheduled to be an 1hr and 17minute flight. It only took 55 minutes from gate to gate. Flight attendant was really friendly, overall a very great experience."
Cons: "The aircraft that was servicing this route was tiny and at times I found it difficult to stand up properly without hitting my head. There was a little chop upon takeoff but besides that everything went smoothly."

Pros: "The fact that I was rebooked immediately to my new flight AC-DC 705 at 8:50 am by two wonderful ladies at La guardia airport who comforted then boarded me unto a flight due to the fact that I missed my original flight. This occured due to the Airport being Unorganized! As I had checked in well before 3 hours and was on time for my original flight at 8:30 am."
Cons: "I was rebooked so my new flight AC 705 was directed straight to Toronto. Only thing I disliked was that gentleman who was left at the gate for my original flight at 8:30am. He was rude!!!!"

Pros: "The crew was very nice"
Cons: "The seats had no padding. Food had to be bought."

Pros: "Nice staff"
Cons: "Unable to buy food or drinks on plane without a credit. I don't have one !!!"

Pros: "Decent service."
Cons: "I paid 100$ for my seat, for more leg room. It happened that the seat next to me was unoccupied. I thought it would give me an opportunity to stretch out a bit to sleep on the Atlantic crossing. Another passenger's tv didn't work so one of the stewardess told him he could sit next to me. He got more leg room for free. I was cramped and could not sleep because of muscle spasm. The Legal age made it more comfortable but it is not worth 100$"

Pros: "I was very kindly provided an upgrade and seat beside was empty, it was a great flight. thank you!"

Pros: "The complimentary snack"
Cons: "That my seats were not together"

Pros: "Everything was as expected"

Pros: "Crew friendly and efficient"
Cons: "Seats!"

Pros: "Overall outrageous fees as per usual"

Pros: "Everything was handled very efficiently, and although it was a commuter jet it was more comfortable than those I've flown on domestically."

Cons: "When we checked in we were told everything was on time. When we should have been boarding, we were told there was no pilot. That took just over an hour to rectify. When we finally landed at Lauderdale, we were told there was no gate - surely they would have known this when we took off from Ottawa!? We sat waiting for at least 45 minutes before having access to the gate. Beyond frustrating when we were already late and inconvienced!"

Cons: "It's my 3rd time flying with this airline, and all 3 flights were delayed without a decent reason."

Pros: "Our flight attendant was consistently nicer than he needed to be with all the passengers, and I think this was after a tough day."

Pros: "The trip went smoothly and it was on time. The Crew was nice and efficient"

Pros: "It was fine."

Pros: "Timely departure, comfortable airplane, decent food&drink offerings, my baggage arrived on time despite 2 layovers"
Cons: "n/a"

Cons: "Very turbulent flight"

Pros: "The layover in Denver worked out perfectly - no long wait. The first leg they announced Gate check early so there were no delays on boarding. On-time flight."
Cons: "The leg room. Small size of complimentary snacks. No United entertainment."

Pros: "Seats tip back pretty far, without cramping up leg room for the person behind you too much."
Cons: "The passenger behind me was playing games on the screen on the back of my seat. So, my seat was constantly being tapped and it was more difficult to sleep."

Pros: "Nothing"
Cons: "Nothing"

Pros: "a little bit more foot-room than my previous flight on a different airline."

Pros: "Nothing"
Cons: "Our flight was delayed 1.5 hrs due to lack of communication, leading me to miss my connecting flight by minutes"

Pros: "leaving on time"
Cons: "Crew's facial expression were upsetting to see since they looked unhappy. Should I be worried about my flight?"

Cons: "Flight delayed due to weather. Rebooking was a zoo, had to pay for hotel room and worst of all waited over an hour at baggage claim to get our bags back. It's taking us 2 days to get from Albuquerque to Austin."

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: "No one could get their story straight and actually lied! I was sent a text (I was already at the airport) that the flight would be delayed due to "aircraft maintenance". Not true in the least bit. Then when we finally landed in Denver (nearly every person on that flight missed their connecting flights) we were told the system said the delay was "due to weather". Another lie. Then they announced there would be gate agents to meet us when we got off the plane to assist with connecting flights. First gate agent said "I have no information you have to go to gate 56". The person at gate 56 said "I don't open for another 15 minutes so you have to go to gate 39"! The real story? They made us change gates 5 times in Fargo! The gate attendant was using the "F-bomb"! It wasn't aircraft maintenance or the weather. They couldn't get the walkway to work! In the end, we still left from the original gate and had to walk outside on the tarmac to board the plane. Why didn't they just opt for that to begin with and avoid all the missed flights? My measly voucher isn't nearly enough compensation and if United ever expects me to fly with them again I am expecting a full refund (as other passengers received- I witnessed the manager in Denver authorize a full refund for another passenger but only offered me $50)"

Pros: "Flight departed on time and landed ahead of schedule."
Cons: "United baggage check in at Orlando Airport was chaotic with huge crowds, inattentive United staff ignoring passengers, and a baggage conveyor belt that was broken down."

Cons: "It was super cold. Miserable."

Pros: "Nothing"

Pros: "Security was quick and efficient. Boarding was extremely organized. The airline attendants were attentive. The pilot on United informed us when the possibility of hitting turbulence occurred so we could adjust accordingly. Overall, great travel experience."

Pros: "Boarding and landing ahead of schedule"

Pros: "Generally it was ok. Travelling is so horrible these days that "ok" seems pretty great."
Cons: "My bag was lost but my husband's, checked at the same time, made it."

Pros: "Nothing"
Cons: "Refused to delay connecting flight in Denver even though severL of where already on ground in delayed flight coming into Denver. Albuquerque flght was still at gate when I got there, having run through airport along with several others. We were refused admission to plane despite delay being United's fault. Unacceptable! I will avoid flying United in the future whenever possible"

Pros: "I didn't fly.I bought the ticket for my son. He had no complaints. You should ask in your questionnaire if the booked flight was for self or someone else."

Cons: "How they canceled one of my flights just as I landed at my layover for that flight when I look back at Boston they had a direct flight ready for my destination. Very poor management I was stuck in Chicago with no money or food for hours then after they start boarding for my new flight they tell me that I may not be able to get on even with ticket in hand. It was a joke and very stressful"

Pros: "Boarding was uneventful, but I wish I could have gotten a gate check....I;m 76 and getting my bag above the seat is difficult. But the gate attendant said there was no gate check on that flight."
Cons: "I had a center seat and that is very uncomfortable for me."

Pros: "Got there on time."
Cons: "Private screening does not work well. Very little kneeroom. No room in seat back pockets to put anything."

Pros: "On-time departure from Cancun but early arrival in Denver (relatively mild jet stream?). Otherwise, fairly typical United cattle carrier."

Pros: "The pilot apologized profusely for our delayed departure, and offered us free in-flight TV. He made up time, and we arrived only 30 minutes late (take-off was delayed over an hour)."

Pros: "Nothing."
Cons: "Airplane went to the wrong airport and caused 3 hour delay . Missed my connecting flight."

Pros: "Suitcase arrived at the carrousel on time , much better than Houston."

Cons: "Delayed and got downgraded without refund of difference"

Cons: "I wish I could have gotten more beverage (water) during the flight. Very dry in the cabin but all-in-all, it was a pleasant experience."

Pros: "This leg of my journey was fine. Sat in the middle seat. Was able to sleep most of the way."

Pros: "Sucks"

Pros: "The option to control my personal tv."
Cons: "Bad service. I was ignored when I it was time to order a drink. The attendant scolded me for using my service button. I wouldn't have used it if they hadn't entirely skipped my row. There were three of us sitting debit cards in hand to order drinks. The same attendant was very rude to a family with a small child and a man trying to put away his baggage at the start of the flight. I will avoid united in the future if possible."

Pros: "Good crew"
Cons: "The usual. - crowded, smelly"

Pros: "The seats had plenty of leg room and I enjoyed the movie selection"
Cons: "The food left much to be desired"

Pros: "Crew was great"
Cons: "Great aircraft!"

Pros: "Flight was on time; both ground and flight crews were pleasant and efficient."
Cons: "They were out of ginger ale, my beverage of choice :-)"

Cons: "Terrible experience ever!!!!! Didn't get economy plus that I paid for, seats didn't recline and luggage got damaged and was not replaces or compensated for."

Pros: "Nothing because they didn't allow us to board the flight because there was 20mins left til the plane departed. Also the tickets were bought with 24hrs and they didn't refund or give us a flight credit."
Cons: "They didn't allow us tothe tickets were bought with 24hrs and they didn't refund or give us a flight credit."

Pros: "Flying in America gave me no problems. Things only got terrible after we left Denver."

Pros: "The service was food"
Cons: "Lack of leg room!!! After my bicycle box was inspected they failed to secure my bike the way I had it in the box. Bike was flipping around in box. Bent rear brake calipers. Bent brake hoods. Rear skewers were uncoupled. No way to treat a $10,000 bike! Very upset!"

Pros: "Had a stroller, two bags, and a car seat and the check in staff helped us tag everything and loaded it for us. It was nice to see the Billings staff go above and beyond in my families time of need."

Pros: "They sent me a text message telling me it was canceled"
Cons: "Unfortunately, despite the text message saying the flight was canceled, the ANA ground staff in Taipei that we talked to assured us it was not canceled. But it was. And so ensued 24 uncomfortable hours of pain. Thanks, United."

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

Cons: "Bad snacks. Need biscotti"

Pros: "It was a quiet and smooth ride."

Cons: "Unreliable wifi."

Pros: "The flight was snooze and the flight staff were friendly!"
Cons: "N/A"

Pros: "Crew was nice and friendly."

Pros: "The flight attendant finally took care of it after I complained a couple of times."
Cons: "That you changed our seats, and, that there was no room in any of the overhead bins. So, the flight attendant told me that I needed to fight my way through the people coming toward me back up the aisle and check every overhead bin all the way back up to see if there was room for my one suitcase. Others had brought more than one bag up there. Finally they checked my one carry on bag. The ride was also really bumpy, worst that we've ever experienced. But that was due to weather conditions."
