Airline reviews

Pros: "The flight attendants were all helpful and pleasant. The seats were comfortable. We were provided with plenty of liquids."
Cons: "The landing was pretty tough and we took off almost a half hour late."

Pros: "Very friendly gate attendants helped us fix the problem that our frequent flyer number had not been entered on the boarding pass. This may have been because of the booking co., Just Fly."
Cons: "Would have liked more seat options, like when I book on Delta's website. Didn't have enough advance warning."

Pros: "Food and entertainment was good"
Cons: "The bathroom I used was disgusting."

Pros: "Crew were helpful and pleasant"
Cons: "Seating was uncomfortable, cabin was cold and no blankets available, food was just ok, plane had lots of empty seats yet everyone was squeezed into 3 in a row making it uncomfortable, no updates from captain or crew as to where we were in the flight....."

Pros: "Anything from free WiFi, entertainment, leg room, commentary drinks and snacks. Great service!"

Pros: "Nothing"
Cons: "Frontier canceled the flight. Delta delayed the flight that I rescheduled. One of the worst traveling experiences I have had in a long time. My day started at 3:30am. I’m just now going to my hotel at 12:40 am"

Cons: "The baggage drop attendant was very unhelpful when I asked if she could help me sort out an issue (when I checked in online for the second leg of my trip, i paid for my bag then but they wanted me to pay again for my first flight) and just dismissed me and said she couldn't help, making me pay again for my bag. First time I've ever had an unpleasant experience with Delta."

Pros: "Gate crew in DEN provided free refreshments at the gate during a 2+ hour flight delay."
Cons: "The aircraft used for this flight comes from LGA as part of an out-and-back. Delays can be expected if there is an earlier departure delay in NYC. On 6/30, this aircraft was 2+ hours late while all other airlines (United, Southwest and Frontier) were all on-time."

Pros: "On time, great service, a lot of legroom."
Cons: "Nothing."

Pros: "The staff was polite and snacks were good (healthy options)."
Cons: "Nothing was terrible, but due to the short flights I assume they don’t worry about having planes with entertainment available."

Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."

Cons: "Was unclear which zone was boarding. Legroom was comprised when passenger in immediate row ahead reclined seat early in flight."

Cons: "Engine problems-2 hour delay"

Pros: "The fact that there was a screen for movie selections and a charging port for my phone and the flight attendants were super nice"

Pros: "Great people and crew early arrival nice passengers"

Cons: "Not applicable"

Pros: "On time as scheduled."
Cons: "N/A"

Pros: "The flight attendant named Steven went so far beyond the call. He was attentive, he fixed our video system when no one else could and when he learned we were celebrating an anniversary he brought us a present. He was awesome!"

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "It's a nice, comfortable flight with plenty of entertainment options."
Cons: "The coffee on board is lousy, but I'm not sure that is much of a surprise."

Pros: "We purchased economy tickets in Delta. With these tickets you don't know where you are sitting until you get to the airport. Well, we lucked out and got the Plus seats! We got free alcoholic drinks, and big plush seats! We left right on time and got there early! Overall a great experience!"
Cons: "Nothing."

Pros: "Great,I loved it!"

Pros: "Everything else fine."
Cons: "Made me check my bag - even though ther was plenty of overhead bin space."

Pros: "Crew"
Cons: "3 hours there before the departure."

Pros: "I didn't like anything because the fly leat 3 hours"

Pros: "First we had a mechanical after boarding. I was rerouted through Atlanta. That flight is now delayed by 2hours. I then had to reroute to West Palm Beach instead of Ft Lauderdale. I will leave 9 hours after my original flight time and arrive 8 hours later. Just ridiculous"
Cons: "See above"

Pros: "When you are delayed, there is not much to commend."
Cons: "Delayed. That pretty well says it all."

Pros: "The crew was good and the flight was smooth."
Cons: "Somehow we were double booked and double billed. We got to the airport 3 hours early and checked our bags. All 3 were lost and searched. Everything was put back precariously and there was shampoo and lotion everywhere."

Pros: "i love the view from the window seats and that I was able to relax and the snacks."

Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."

Cons: "Seats too close - I'm not that tall and my knees were jammed against the seat in front of me."

Pros: "Was able to get on a flight after ours was cancelled. Delta was in scramble mode and their gate staff worked hard ot deal with a frustrated flying populaiton"
Cons: "After paying for first class round trip airfare, we were given seats in coach in the rear of the plane, in spite of empty seats (plenty of them) in first class and economy comfort."

Pros: "Plane was comfortable"
Cons: "In order to leave airport on time (plane came in late) they claimed overhead space was full and that remainder boarding passengers had to check their bags. (Bags to be picked up in baggage claim) When walked into plane saw plenty of overhead space for carryons!"

Pros: "Plane was clean and staff were friendly"
Cons: "The snack options were quite average"

Pros: "Flight attendants were lovely"
Cons: "Nothing"

Cons: "No complaints."

Pros: "Flight took off on time and arrived about 30 minutes early."

Cons: "I had no room to move and my legs were stuck"

Pros: "Only 15 mins."
Cons: "Seats were tight."

Cons: "The people taking the tickets were rude, only in Atlanta. The people in Denver taking tickets were very friendly."

Pros: "The crew is the only postive thing about this flight..."
Cons: "Bordining unloading and in general the comfort thing is a joke...."

Cons: "I travelled from usa to canada on 7 nov and after 2 hours waiting in airport they informed us that due to some issue Delta can not deliver our bagagges also one of Delta airport's staff behaved very badly (his name was Manny) , helpless and rude.I missed an important dinner meeting because of not having any suitable dress. I have many friends and family who lives in canada and usa but by facing this bad behaviour and problems never ever recomnd your airline to any of them."

Pros: "Crew was great."
Cons: "Boarding process was a bit chaotic"

Pros: "Left early and arrived early"
Cons: "Cabin was way too warm. Also not as much space on 737-700 as 737-800"

Pros: "Pleasant and helpful stewardess. When they found out how stressful our day was with delays and being bumped around they offered us a free drink. Nothing crazy but it was kind of them."
Cons: "When our flights were delayed then changed we were left with no options other then being left with a 19 hr layover in Vancouver and missing the wedding. No apologies or vouchers offered. Air Canada gave $200 for a two hour delay to our friends, we were screwed over and offered nothing. So disappointed. We ended up flying to Vegas and renting a car and driving through the night to be on time. So sad!!"

Pros: "I received great service and the flights were on time."

Pros: "The flight attendants were great"
Cons: "No power chargers on the planes"

Cons: "On time"

Cons: "The flight left without me"

Pros: "Good service. And snacks served"

Pros: "Good legroom compared to other carriers"
Cons: "Almost 1 hour late leaving. No westjet connect, so no entertainment."

Pros: "The over all star rating should have five stars. I mistakenly pressed something and it went to one And I could not figure out how to get it back to five. Everything was on time which I so appreciated."

Pros: "Professional, efficient, courteous."

Cons: "Plane seemed older and less leg room for a 6’4” guy. No TVs or monitors to track flight info."

Pros: "Flight steward did a good job explaining safety procedure for exit door"
Cons: "One hour and ten minutes late. Arriving after midnight with one notification of a 30 minute delay not 70."

Pros: "Upgraded to Plus - it was great."
Cons: "Too bad we have to pay extra for Plus to get a reasonable amount of room."

Pros: "Crew good, service good"
Cons: "Both flights delayed over 2 hours, missed connection so it took so I was in airports 13 hours instead of 6"

Pros: "Everything was very streamlined, from boarding to landing."

Pros: "It was a clean plane and a pleasant enough flight."
Cons: "I was in the window seat. The guy in the middle seat spread out so much he was pushing me against the side fo the plane. Really uncomfortable."

Pros: "Flight was good."
Cons: "Was boarding at C70 but only saw signs for 71 and C73. Asked Westjet staff where we were boarding and they told me (and others) that even though we were booked to take off from C70 we’d be departing from the gate labeled C73 and also labeled for a flight to Regina. Still got to Hamilton though."

Pros: "The crew was very friendly and funny"
Cons: "Everything was up to my standard"

Cons: "It did not happen. Being transfered to air canada in Toronto was a night mare"

Pros: "The stewardess serving drinks was very pleasant. Thank You"

Cons: "Big 4 hour delay caused that we missed another flight in London"

Pros: "The crew were friendly and professional; the flight was safe--by far the top priority!"
Cons: "The plane needed a jump start before we could leave Vancouver (this was during daytime, sunny skies, about +1°C), which didn't inspire confidence in the plane's airworthiness and which delayed our departure by almost an hour. But evidently the crew followed the required procedure and we arrived safely in Calgary. Better to be a bit late than to have an unsafe flight."

Pros: "As always, the staff and crew were great. Left on time, arrived on time they go their best to deal with the shortcomings of the company."
Cons: "The entertainment system (or lack thereof...) not nearly enough iPads to rent and it never works on laptops."

Pros: "Great efficient crew."
Cons: "I miss the free movies..."

Cons: "not being able to change flight"

Pros: "The flight and crew were great, great flight. Arrived earlier then stated. I still enjoy flying in and out of Hamilton. Great airport. If I can book West jet again, I will, great airline. Took some great pictures from the aircraft. Thank you !!!!"
Cons: "Security, too much, even when we arrived, customs twice."

Pros: "Short flight"
Cons: "Nothing"

Pros: "Great experience...."
Cons: "There were wait times...too long"

Pros: "Main stewardess was very pleasant. Not full flight so I moved back and had a seat to myself."

Pros: "The roominess, service, food.....all excellent"
Cons: "It would have been so much better if there was a foot rest."

Pros: "Comfortable seat with lots of leg room"

Pros: "The crew were polite friendly great customer service"

Pros: "Nice crew"

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."

Cons: "I was traveling with a piece of artwork and had to check it in oversized luggage, but as I was going through customs, I wasn't allowed in, because the Westjet team couldn't find it. I was escorted to their waiting zone, where I spent 1.5 hours waiting in limbo trying to figure out what I could do. Thank goodness the flight was delayed 80 minutes, because I was finally able to make the flight with 2 minutes to spare after running to the gates. The flight time, 65 minutes. I find it hard to believe the flight got delayed an entire flight. To couple that, when the plane landed in LGA (where I am as I write this), we're stranded on the runway because we don't have clearance to pull into our taxi area."

Pros: "The crew and staff were great on the plane. Could use more staff at the checked bags area but overall good experience"
Cons: "More agents at the check in desk"

Cons: "I was able to download the WestJet Connect app on my phone which gives you access to tv shows and movies to watch on your own device during the flight. The app was free and easy to use and there was a decent selection. However, the wifi on board is not free so even though you could watch the tv show/movie - the sound did not work unless you paid for it. There are many other airlines that offers everything for free - it would have been a more pleasant if we were able to actually utilize the service."

Pros: "Great crew, West jet connect worked fabulously"
Cons: "Cramped space and airplane food"

Pros: "We got some extra help in the airport :). Thanx"

Pros: "WestJet staff very friendly & helpful"
Cons: "Toronto airport needs clearer signage - very confusing"

Pros: "Awesome crew, chill experience !"

Cons: "They didn't let us know ahead of time and there wouldn't be televisions. If you hadn't downloaded the WestJet app you couldn't watch TV. You had to rent a tablet for seven dollars or buy an Internet package to download the app. That's fine just frustrating"

Pros: "Friendly crew. We were able to check our carry on bags to our final destination for free, since it was a full flight."
Cons: "Was surprised that a there was no checked baggage allowance or meal included, especially for an international flight!"

Pros: "Left on time, arrived early!"
Cons: "When checking in, it indicated a smaller plane. I was not in a window seat and I had to check my baggage (and wait at the baggage terminal)."

Pros: "Captain asked passengers not making close connections to allow passengers with connections to deplane first was very helpful."
Cons: "Flight left late and arrived late making my connection in Philadelphia for a flight to Budapest a very close call."

Pros: "Prompt on time service."
Cons: "N/A"

Pros: "American"

Cons: "Two hour delay out of Denver, no crew."

Cons: "Such tiny seats."

Pros: "Crew was nice."
Cons: "Plane was very old (from the 90s?), cabin kept freezing all night. Now my husband's luggage has been lost and we are getting conflicting information on how to retrieve it."

Pros: "Comfortable flight except for limited leg room. Great movie selection."
Cons: "Poor leg room for tall people"

Cons: "They changed my flight schedule that made me have to arrange my travel plan"

Pros: "Not using kayak"
Cons: "Kayak booked me the worst itinerary in the history of air travel!"

Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."

Pros: "British Airways got us on another flight to Dublin through Heathrow."
Cons: "Plane was late missed the connecting flight. Aer Lingus/American Airlines refused to help us find another flight to Dublin. I called Vagama customer service and the attended refused to help get an additional flight or confirm our returning flight would be held."

Pros: "The helpful steward"
Cons: "The bumpy ride"

Pros: "fairly comfortable, crew was helpful"
Cons: "Having to use my phone for entertainment, with no place to plug it in"

Cons: "I'm not sure where the problem was - whether with AA or Royal Jordanian, but my luggage did not make it to Amman with me. In fact, there was a whole group of passengers traveling on American from different US cities, switching to RJ in Chicago, whose luggage did not come on the flight to Amman. My advice: be sure to pack enough for a couple of days in your carryon - and don't accept an offer to check your carryon to its final destination!"

Cons: "We had five pieces of luggage lost during our flight from the U.S. to Spain. When we arrived in Madrid we were told that all five pieces had been located. When we went to pick them up the next day there were only four pieces at the airport. We were told the fifth suitcase would be delivered when it was located. It's ten days later and there's no sign of the luggage. It has taken multiple phone calls to get the information about the luggage correct. They assure me that they have everything correctly documented and then when I call back they haven't changed a thing. It has been a very frustrating process overall."

Cons: "The layover was too short we missed our connecting flight. How did Kayak even allow us to book such an itinerary. Staff with the airline was also rude! Never will I book with site ever again!Rude"

Pros: "Arrived early"
Cons: "American airlines lost my bag... Customer service in LAX is non-existent."

Pros: "Comfortable seats, good legroom."
Cons: "Not enough coffee for breakfast."

Pros: "Arrived 20 min early. Smooth flight."
Cons: "Didn’t have individual movie screens."

Pros: "Seats were comfortable enough"
Cons: "They force you to get to the airport really early."

Pros: "Food and entertainment were great"

Cons: "This was a BA flight on an American Airlines plane. Very small crowded and uncomfortable. My husband is 6'2" and barely fit in the seat."

Pros: "The crew was awesome."
Cons: "You guys lost our luggage!"

Pros: "Good connection"

Pros: "I like that American offers free movies thru their app but there was a glitch and I couldn't get it to work!"
Cons: "Couldn't get the entertainment app to work"

Pros: "There was nothing too bad other than I wasn't able to check in online bc our first leg of the flight was operated by American Airlines. But there wasn't anything that really stood out that would make me want to fly them again other than it was the best price."

Pros: "The crew was very helpful at each stop even though they weren't responsible for the disasters."
Cons: "Initially we thought we were flying with British Airways. We then had to do some digging to realize it was all out of American Airlines. Then we couldn't get proper boarding passes and luggage tags until one of the crew members spent a significant amount of time untangling each leg of our trip so they were in the proper order. We got delayed by 4 hours in Chicago and missed our connection in Manchester. We had another 5 hour wait there. By the time we got to Dublin, our bags didn't also arrive. After almost 24 hours of travel, we arrived but without all of our stuff."

Pros: "Easy flight, friendly crew."
Cons: "Girl next to me being sick the whole time"

Pros: "Flights attendants were super friendly and the plane was very clean"
Cons: "seats are uncomfortable"

Pros: "Excellent, friendly attention from flight attendants."

Cons: "Late departure. Seats were double booked. Had to delay again to sort it out."

Pros: "I liked everything from the way they got everyone on the plane to getting everyone deplaned."
Cons: "I didn't have a problem with the airline. Just a couple of passengers."

Pros: "My departing flight crew was very accommodating for my baby and I. They were very pleasant."
Cons: "I wasn't able to board first with my baby, so I had to try and walk through all the passengers with a baby, diaper bag and small carry on. It was a little difficult."

Cons: "I had a severe back injury in Denver and they were unable to move my flight up a day to get home and see a doctor. A good friend had to buy me a new flight with his airline miles so that I could get home to relive my pain. I'll never fly American again because of this complete lack of compassion and care for their customer."

Pros: "On time. Good crew and nicer flight."
Cons: "Actually no complaints."

Pros: "The flight was fine"
Cons: "Both flights each way where delayed significantly"

Cons: "Flight was canceled going back to denver from Augusta. American did nothing to compensate me for their mechanics breaking. Had no place to sleep and no transportation as I return my rental. Poor customer service will never use American again!"

Pros: "Seat was comfortable, and my favorite on this aircraft - 3F on the MD80. Boarding was quick, and service was efficient once airborne."
Cons: "AA crews are skimping on pre-departure service, rarely offering PDBs (pre-departure beverages), or, when they do, half-assing it by putting water and OJ on a tray and making it clear nothing else is available as they did on this flight. It sets the expectations very low for the rest of the flight, and that's what happened."

Cons: "American delayed the flight 7 times before cancelling it. They then put me on a flight 7 hours after the initial departure time. That flight was delayed 7 times and then they cancelled it. I wasted 10 hours at the airport."

Pros: "how easy it was to purchase ticket on kayak."
Cons: "Being charged for my checked bag unexpectedly at check in."

Pros: "My business class seat was comfortable"
Cons: "4hr boarding delay and no entertainment system whatsoever on a 6hr flight."

Pros: "Space security manners"

Pros: "Seats were comfortab"
Cons: "The flight attendants, could have been a bit friendlier"

Pros: "Cool TV roomy seats , friendly staff."

Cons: "The new seats were so uncomfortable, I couldn't sit shoulder to shoulder with the people next to me"

Cons: "Still in the waiting room waiting for this flight"

Pros: "Arrived home safely"
Cons: "Arrived very early due to logistics and our flight was not leaving for 9 hrs and the AA Representative would only put us on a earlier flight if we paid a large fee, so we waited then the original flight was delayed 2 hours and we nearly missed our connection in another city, it all could have been avoided if a little flexability and care were involved to put us on a earlier flight"

Pros: "Good"
Cons: "Everything"

Cons: "No movie, overnight flights would be great with side head rests, stewardesses were not nice, just ok"

Cons: "Food had little taste. Movies were not that current and selection was sparse"

Pros: "Crew was great!"

Pros: "Cabin crew were terrific!"
Cons: "The unfortunate delay of our flight. And the entertainment systems seems to be getting old. What I mean is that it is by todays standard very very slow to switch between menus etc. And in some cases did not display all the menu content."

Pros: "Not much. Crew was good but that is about it."
Cons: "Tight spaces packed in like sardines. FAA seriously needs to look at how these airlines pack us into these seats. Can barely sit in the set, no room to stretch legs, tray table hits my stomach, and I don't even have a big belly. When the guy in front reclines, cannot even get out of my seat. Chaotic boarding process without any order or instructions or announcements, poor food and entertainment."

Pros: "Good boarding.Easy check in."
Cons: "Food! Not appealing. Did not eat more than a few bites."

Pros: "1 stewardess was great"
Cons: "Flights were delayed. Did not check boarding passes which was scary."

Cons: "Rather than notify the passengers that our flight would be delayed prior to our arrival at the airport, we waited at the gate for several hours."

Pros: "put us up in decent hotels gave food vouchers the crew didn't do anything to make it horrible Large selection of movies/tv on board comfiest seats out of all the major airlines I've flown"
Cons: "The flight kept getting delayed bc of mechanical problems, and then eventually cancelled. They rebooked everyone on new flights, but it took an extra stop in Toronto before getting us to Montreal. Once it was rebooked for the morning, it took off a little late. Plus the pretzels they gave us were stale. This was the first of two flights I took this trip that had mechanical issues, so they obviously need to fix their planes better or get new ones, because two Air Canada flights in one day that have mechanical problems leaves me worried that the planes aren't in optimal condition. It took me over 24 hours to get from Tucson, AZ to Montreal, Canada when normal travel takes less than 8 hours including layovers."

Pros: "I had an aisle seat"
Cons: "The plane sat on the runway in Denver for over an hour because they couldn't figure out their furling situation. Many people nearly missed connections because of this. The crew never let us get up to go to the bathroom on an international flight because of some small turbulence."

Pros: "Nothing! Unpleasant unhelpful crew at gate, no better onboard, absolutely moist cramped seating ever! Disorganized and late- boarding, departing, waited to disembark at arrival, 25 min before first bag off baggage......dreadful no one cares"
Cons: "Thank you for choosing Air Canada- smiles and goodbyes- where's all that Before you leave? They treat you like problem cattle to be dealt with, you're anonymous and valueless until you leave then they look at you and thank you?! Missing sincerity And service!"

Pros: "Onboard attendants were pleasant"
Cons: "No apology for lateness, flight boarded late, took off 40 min late, arrived 35 minutes late but we sat at gate waiting for someone to open it ?!, then another 15 min before bags started to unload Ridiculous but indicative of airlines You are not their valued guest or even their customer, you are a problem that needs to be solved and are consequently met with preloaded annoyance and a readiness to dismiss, placate at the best of times but definitely not please, impress, sympathize or satisfy. There is no evidence that it's even in their lexicon- not a part of their recruitment or selection process or training, ever! They're main focus and only positivity is saved for themselves. There may be a long line of concerned and anxious travelers but their priority is getting coffees for the battle ahead! They break their focused indifference only for each other and enthusiastically leave their post to satisfy each other's needs and attention. This has got to change! Why do we put up with such awful service for which we are the paying customer? Why are we, their customers, not valued? This airline makes record profits, provides less, charges for everything and increasingly delivers bad service, sometimes offensively bad! It doesn't cost more to hire a customer centric pleasant person, or incorporate guest experience into training or at the very least be friendly and smile! What if an airline just did that?! They'd differentiate themselves and develop a positive customer centered culture. Don't we deserve that, at the very least?!"

Cons: "Crew wasn't helpful and attentive, boarding staff in Toronto were blatantly rude to me, I watched as my luggage got handled aggressively, the plane was dirty with old food crumbs and such, my flight to Windsor got cancelled and accomadations were not met sufficiently."

Pros: "I like that Air Canada provides entertainment and its flight attendants are really good."
Cons: "I rarely fly these partner airlines without experiencing major delays, and the delays are always announced after I have cleared security, forcing me to spend hours at the airport. The claims of "weather" are specious: they don't fly enough planes and they don't properly maintain the planes they do fly."

Pros: "Crew was nice"
Cons: "Couldn't use in flight entertainment, only half a soda was given"

Pros: "Nothing"
Cons: "Customer service flight rebooking"

Cons: "No monitoring of travel route"

Pros: "An Air Canada rep over the phone"
Cons: "Gate agent, zero entertainment (and no warning that we should download an app inside airport), poor food, flight attendant wouldn't bring coffee to us (made us go to the back)"

Pros: "Upgrade to premium economy with more legroom. Free movies. Good movie selection. Free checked luggage!"
Cons: "Check-in process at Denver counter rather slow. Gate information at Denver very confusing due to changes and lateness in displaying/announcing information."

Pros: "I thought the crew was friendly."
Cons: "The seats were incredibly small and uncomfortable. No snacks were offered."

Pros: "At least there was food tho only banana bread for breakfast"
Cons: "No movies or entertainment for overnight flight"

Pros: "I enjoyed the entertainment option."
Cons: "Wish there were more choices for new movies."

Pros: "Quick flight, well-done!"

Cons: "Flight was cancelled and they did not bother to inform us! Ended up flying on United and arrived 6 hours later than planned."

Cons: "Flight delayed. Attendant told us to come back tomorrow and we could get on the same flights just a day later. Really?? not that stupid. Had problems getting a room overnight - management said we weren't in the system. Gentleman at air canada desk very rude - even told his partner in front of us he couldn't stand this part of his job."

Cons: "Short movie list"

Cons: "Flight was great. Kayak was a nightmare to work with."

Cons: "The fight itself was fine. Not great. Not terrible. But the airline lost my son's suitcase and has been entirely unhelpful ever since then. Now we have been stuck in a foreign country without clothes and toiletries for 36 hours and Air Canada's "helpline" has been anything but helpful. They can not find any information on the location of the suitcase and hope that they will find it in another 48 hours. Rediculous!! I will never fly them again and suggest that you save your money, effort and vacation by flying with another airline."

Pros: "Decent flight"
Cons: "Delays are part of travel, but they're ridiculous and I am unhappy with the delay leaving Minneapolis. It caused all sorts of problems down the line because it caused me to miss my connection, take different flights, and come into Munich much later than I had expected. Also, you Canadians don't have Sudoku in your magazines. Why?"

Pros: "nothing"
Cons: "i booked a flight through kayak going from denver to milan. i showed up at the airport in denver to fly out yeserday only to find out that i was going to frankfurt germany. i am now in munich germany and never made it to milan. i was one of many people i met on the flight that also booked with air canada thinking they were headed to milan. air canada kept trying to put the blame off to my booking company. i don't know who to be ticked off at. please advise."

Pros: "Great crew. Nice airline."
Cons: "Both flights were over 30 minutes late. Otherwise they were just fine."

Pros: "Better plane than previous"
Cons: "Had to be rerouted to Calgary because I missed my connection"

Pros: "How quick it waz"
Cons: "How close the seats were"

Pros: "All services and most of all excellent customer services."

Pros: "Friendly crew. Very smooth flight. Easy to navigate terminal."
Cons: "Nothing!"

Pros: "Leg space, arrival on time"
Cons: "Had to pay for food and cheap earbuds"

Pros: "Airplane was clean and crew was nice."

Pros: "Glad for this new route. Will make Europe easier to access from PDX."

Pros: "Plane arrived pretty much on time. Boarding was uneventful."
Cons: "Plane too low to use jetway at Pearson. Epic walk from US gates to immigration. Insufficient leg room if you're over 5'10", but that's how it is these days."

Pros: "I liked the way they handled the rain delay. Although inconvenient, they were transparent with the process"
Cons: "The lack of certainty whether we were removed or stilling our connecting flight to delay."

Pros: "The entertainment. The first meal was decent."
Cons: "The crew was really rude, didn't respond to the call light, and took 2.5 hours to present headphones to everyone. I thought they were joking when they brought out a third of a sandwich for the "snack"."

Pros: "Nothing."
Cons: "The flight attendants on this flight did NOT do their job. If they are there to ensure a safe environment for the people on board, they completely missed the boat. I was in row 45. Two families were on board with their 4 very young children. For the entire 8 hour flight, 3 of these children disrupted the entire section of the plane. They continuously played in the aisles, stood in the seats, kept their seat belts unbuckled, threw objects, and one blasted his iPad at maximum volume. When I asked one flight attendant to ask the family to get the child to lower the volume on his iPad (it was 4am; people were either using their ear buds, or had their screens turned off), they complied with the request for 30 minutes, then resumed at full throttle. I can honestly say, it was one of the worst flights I have ever experienced in 57 years."

Pros: "There was entertainment on board although it was very limited. All of the crew were very helpful and professional."

Pros: "crew"
Cons: "delayed due to computer malfunction, food awful, missed my connection, had to wait for 6 hours"

Pros: "Everything was well organized and we were able to depart sooner than scheduled."
Cons: "There were some items on the menu that were not actually available."

Cons: "Very crowded, small seating and legroom"

Pros: "I will fly Air Canada again but will probably drive to Toronto to catch a plane, rather than take the connecting plane out of my own city.There's a Tim Horton's at the airport!"
Cons: "Flight from our small city was late leaving and we didn't find out about the delay until close to the take off time. The reason given to us was that there was too much air traffic in Toronto. Couldn't this have been planned better? Not the fault of Air Canada."

Cons: "Even though this flight was operated by CA and booked through Ethiopian, they would not honor my two checked bags. However, the guy behind me - also going to Ethiopia - they allowed two checked bags, no charge. I always feel like they aren't willing to budge or look up the rules or even just be nice about baggage. I'd rather not give any more $$ for baggage that i'm actually allowed."

Cons: "Over 1 hour waiting on phone and disconnected. Terrible. Check-in people didn't even say one single word of apology. they suggested call Air Canada."

Pros: "The crew was friendly, there was entertainment available via the display on the back of the seat."
Cons: "The touchscreen display wasn't working properly, making it difficult to control things like volume. I would have preferred a display with physical buttons that took a bit more time than the weirdly synced touch screen"

Cons: "When the flight was overbooked I did not get my flight because I checked in in person and not online. That is bullshit. They were nice to figure out the best alternative but I still lost hours to figure it out, leave and come back."

Pros: "Landing safely"
Cons: "Late departure. Poor food sale selection"

Pros: "Service all crew excellent"
Cons: "Boarding tome"

Pros: "Nothing"
Cons: "Our flight was delayed which caused us to miss our international connection. Flight attendants did not care, did not attempt to get us out faster, or put on a different flight. Asked for an announcement to be made on board or to be moved to seats closer to the front so we could get off the plane quicker, did not happen. Offboarded and sprinted across the airport for our international connection and was notified by gate attendents that the gate closed five minutes ago and that they could not let us on the plane. Meanwhile, the plane sat there for an additional 30 minutes while it fueled and waited for release from air traffic control. There were six travelers total stuck there in San Fran at that gate, all of us begging to be let on the plane to Beijing, the last one for over 24 hours. Zero compassion from staff at the the airline gate. They did not care about us and did not care about leaving their travelers stranded. Our total travel was Denver to Bangkok, 26 hours of travel including layovers in San Fran and Beijing. In San Fran (after missing the gate connection), United rerouted us through Haiwaii and the customer service agent that did this reroute did not finish the reroute to our final destination. We got to Haiwaii and were stranded again, at the United service desk for four hours having to once again provide documentation of our initial travel plans to Bangkok, having them build a new itinerary to our final destination. Overall, 20 additional travel hours have been added to our itinerary, almost double our initial travel time. We have had to call and cancel pre-arranged bookings in Thailand as we are now missing two full days off our trip. I am absolutely disappointed and heart broken as I write this still stuck in the Beijing airport waiting another six hours to connect to Bangkok. My fiancé and I were traveling to Thailand to get married and have received no compassion from anyone at this airline to try and get us there. I fly United for work quite frequently and have never experienced such horrendous service and lack of basic human compassion. I am flat out disgusted by United and will not be using them again, for personal travel or work related trips, because of this horrendous experience."

Pros: "Comfy seats! So nice when you have a comfortable chair"

Pros: "The layover in Denver worked out perfectly - no long wait. The United entertainment availability. Friendliness of crew. On-time flight."
Cons: "The leg room. Small size of complimentary snacks. No screens for United entertainment so you had to use cell phone, but this eats battery and no power in our zone"

Cons: "2-1/2 hour delay due to poor maintenance"

Cons: "Seats in economy were cramped! Chair barely leaned back at all. Woke up with a sore neck. Cabin was freezing!"

Pros: "The flight attendant was trying to be accommodating. I and other passsengers bumped our heads when getting into seats. Can we say SMALL plane?"

Pros: "The crew"
Cons: "The seats r too small"

Cons: "I missed my flight due to a nonsense delay from Charlotte. Arrived at the gate 1 minute after scheduled take off and the plane was gone. Not even an attempt to waiting as I ran, 5 months pregnant, through the airport. I was rebooked to arrive in Las Vegas at midnight. 12 hours after the original time. I bought a flight from Southwest. I will never fly united again"

Cons: "No food no entertainment. It's a sad change from how United used to be"

Pros: "On-time departure and courteous crew. Smooth flying on this leg of our trip."
Cons: "I don't have any major complaints about this flight."

Pros: "The crew were polite and friendly."
Cons: "A cookie was the only snack on a more than 3 hour flight."

Cons: "Very long walk from aircraft to immigration"

Pros: "Nothing"
Cons: "That my flight got delayed in Denver over an hour and I missed my flight from LA to BJX because of that. I was suppose to land in BJX At 6am on Friday April 28th for a family emergency and now my next flight isn't till 1pm! This is the worst flight experience I have ever had in my life. Never in my life will I ever fly with united again. My plans got ruined, I was forced to sleep on the cold dirty floor of LAX. This cost me a lot of time and money, and I am upset about it. I will tell all my peers about this horrible experience and encourage them to never fly with united ever again. I do expect some sort of compensation over this horrible experience."

Cons: "Flight was delayed for 2 hours"

Pros: "On time from Checking In and Departure"

Pros: "Nothing was positive"
Cons: "Whole experience was terrible"

Cons: "Tight seating for transatlantic flight. More importantly avoid Toronto at all costs. Need to clear customs and go back through security again on a connecting flight. Takes forever. Food was not good at all."

Pros: "Phone charger at every seat"
Cons: "Earphones for movie did not work"

Cons: "Very late."

Cons: "Boarding by zones causes passengers to have to stand longer while waiting to board, inconveniences them by having passengers seated in window and middle seats often arrive after the passenger in the aisle seat, and slows down the entire process because passengers settling into the front part of the plane frequently board and stow luggage while those seated in the back queue up behind them. Compared to boarding by row, the entire process is now one lengthy mess."

Cons: "My flight was ten hours late and no accommodations were provided. 40% off tickets to hotels and no way to get to them."

Pros: "I liked the power outlets that were available, as well as the USB! I have trouble sleeping on flights, but the great options for the in flight entertainment made it more than bearable. I will always choose to fly United now."

Cons: "Very bumpy ride....but I realize that can't be helped"

Pros: "Nothing is good about united."
Cons: "Had to fly into Memphis instead of Nashville in order to make my event. United didn't even help me do it, I figured it out myself . Asked for a refund and they gave me $3. Had to drive 4 hours and rent a car for $75 just to make my event on time that I had planned months ago. United is a terrible airline and I will never fly with them again."

Pros: "Amazing plane with great features! Incredible staff!"
Cons: "Bathrooms should be bigger"

Cons: "Delayed and got downgraded"

Cons: "Upon approach we were suddenly deverted to Seattle. I had a few issues. Number one you could not hear the pilot so that made it worse. The lack of communication was horrible. I have been on flights when there has been clarity given a change in plans but this was bad. We sat at the gate for an hour and a half, again no real communication, the fligh attendant t hope was joking when he said there was a half a bottle left for the whole plane...much later we were served water. Announcements were made but no clarity. We were told to collect baggage at number 2. Get a voucher for a hotel. After deplann9ng about 25 of us stood in line at the customer service desk where there were two staff working slowly. Then after an hour they announced we were in the wrong place, couldn't that have been explained earlier? Once we made our way out of the terminal to the ticket count the line was all the way down the hall. still with little info we waited. We landed at the alternate airport at 945, at 130am I had my vouchers, the food not useful until the following day, the hotels were full, no one picked up the phone for the shuttle bus to the hotels. I finally elected to sleep at the airport on a bench. We had actually all been reassigned a flight on our same plane. So I am not sure why we had to wait in line all that time. Our bags were not removed from the plane an irritated baggage claim attendant told me. It was a mess. The flight the next morning was fine, short, without problems for me. united needs to work on its communications. It would have been helpful to have someone out side running the line giving out info. And at customer service they should have been paying attention to their line. Would have been helpful."

Pros: "nice flight attendancts"

Pros: "Good crew, smooth flying, on-time"
Cons: "Crowded"

Pros: "Empty plane do had lots of space. Super comfortable."

Pros: "There was a lot of space and a quick departure."
Cons: "When we got to LA event though we were early we had to wait. I know its not the airlines fault but it sucked."

Pros: "The crew was very kind to everyone and it was a very pleasant flight!"

Pros: "Crew was great"
Cons: "Aircraft interior is dated."

Pros: "Hard working efficient crew. On time; a pleasant flight. Excellent flight attendant who covered all requests on her own."
Cons: "No problems"

Cons: "The plane temperature was ice cold and I was miserable the entire flight home"

Cons: "Nothing"

Pros: "The kindness of the staff."
Cons: "Having to go back to Denver because of a storm-in Omaha."

Pros: "I"
Cons: "I think United is improving constently"

Cons: "Seats are not comfortable and no leg room"

Cons: "Crew was not particularly friendly. One man was brusque when I asked for water to fill my small bottle. Rare since most crew members I've experienced have been very pleasant. Snacks were pretty paltry. Ned to serve some biscotti."

Pros: "Everything went smoothly, and that's really all that matters. The crew was great."
Cons: "Don't know why we have to pay for entertainment. It used to be free."

Pros: "I liked the flight attendants that they were courteous and helpful"
Cons: "I am a fearful flyer and that is putting it mildly. I didn't like that the pilot didn't introduce himself and talk to us about the flight."

Cons: "i missed my flight because my flight left Toronto late"

Pros: "I liked nothing"
Cons: "I didn't like everything. All my United flight were delayed, the international was cancelled after waiting for 7 hours of delays."

Pros: "Crew nice and friendly."
Cons: "Free in-flight entertainment should be offered on all flights of 2+ hours through the United app. Had a family with young kids next to me who would have benefited from it (I saw the father trying to connect to it through the app), and overall it would make the flight a much more pleasant experience. After boarding a full hour later than what was originally said, it would have been nice to kick back with a movie for the flight."

Pros: "I know it's some sort of miracle. But there was only 40 people on an airbus. We all had about 3 seats each and we made full beds for ourselves."

Cons: "Boarded and left late for many to miss connections. No real help to get to new connection both on plane and off."

Cons: "Delays! Numerous delays! No assistance to help with changing missed connections or getting a hotel while stuck in Chicago."
