I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

Terrible. Out flight was delayed for 21 (twenty one) hours. United is a joke.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

Standard short hop flight. No food, no entertainment. Just get in, get something to drink, and try to be as comfortable as you can for an hour.

Cancelled my flight. Only option had a layover in Italy. No compensation for the 4 extra hours of travel time. The travel agency, cheapflightfares, blamed Scandinavian airlines and said there was nothing they could do. Scandinavian airlines said since it was booked through a travel agency there was nothing they could do. The entire thing was incredibly frustrating. Never booking through kayak or with Scandinavian again.

Name change on tickets for a misspelled name was very hard to change

Very helpful in getting us off the plane first to make a tight connection.

Very unfriendly approach to me when you rescheduled my return flight due to your delay. No help to address my health concerns because I am diabetics and had orthopedic problems. No clear explanation where to clear customs. I had poor customer service

The seats were really cramped. The high backs on the chairs made you feel claustrophobic.

Boarding was chaotic and the flight left late but arrived at a decent time. This may have been because of the sxsw festival that was going on.

The flight got canceled and you just send an email in the middle of the night and no solution to how to get on the next flight or provide other solutions.

You cost me my time and did not compensate properly. Gfy.

Missed a connecting flight and SAS was at fault. I was awarded a $20 voucher in exchange for 8 hours of my time? Gfy.

Seats in premier saga class were narrow and hard. Very uncomfortable for a 5-hour flight.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset. If there is option to use another company, I suggest to other people use them.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.

Horrible. The flight was delayed by over 3 hours but updates were barely provided. Boarding started 3 hours late then stopped because their system crashed. So now, passengers were standing for 15 minutes in the open waiting to get boarding passes scanned and get on a bus. Duty-free closed around 4-4:30. Only 1 food outlet was open and it was super slow and busy since it was serving passengers from multiple flights. So a number of passengers couldn't buy meals at the terminal. Since the flight was delayed by over 3 hours, we could have been offered snacks on-board. Nothing. The seats barely reclined. In-flight entertainment options were pitiful. Overall, a miserable experience. Never flying on Icelandair ever again. :(

For a no frills flight this was surprising comfortable. The crew were helpful and nice. The flight was smooth and there were no delays or issues which I haven't had on a flight in a long time. I would definitely fly with them again.

The flight was canceled by play less than 24 hours prior to the trip, and I was unable to re-book. Have not received a refund for the trip despite filling out the appropriate form.

Was was cancelled less than 24 hours prior to my scheduled departure by PLAY. Despite my attempts to rebook my travel, I encountered significant cost increases that rendered this option unfeasible. In accordance with EC Regulation 261/2004, airlines are required to issue a full refund for cancelled flights within seven days of the scheduled departure if a refund is requested instead of rebooking on another flight. It has been three weeks without a refund or an answer

It would have been better to have USB charging ports available on the longer haul Flight that one of 2 hours

Was very good Staff was great. No tv monitors tho. So long flights make it longer

The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.

Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time

have screens on backs of chairs...offer free snacks and water

Boarding and crew was great. Flight was cold, need layers. Deplaning was hard. We had to take stairs off the plane and I was separated from my travel companion because we were not seated together and they would not let him wait for me to get off so we were forced onto different shuttles.

The payment system was not working so was unable to connect wifi the entire flight

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

Our luggage didn’t arrive with us, that puts a damper on the whole trip.

The screen didn’t work and I didn’t get the seat upgrade I paid $300 for. They were no help with that,

Paid $180 for seat selection, and selection essnt honored. Have to call for a refund.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful

The internet was horrible. Plus they charged me $25 for service that didn't work which should have been free since I'm Concierge Key. The flight attendant Rick Young was excellent. Greeted me by name and very attentive.

Not good. First time flying AA in years and won’t be doing so again. We departed late and missed our connecting flight to Barcelona. As a result we missed the first two days of a Mediterranean cruise. No reason given for the delay. Got rerouted from JFK to Heathrow and then to Barcelona. Flight to Heathrow was delayed causing us to miss the flight to Barcelona again. Routed then to Palmero where we had to purchase transportation and a 2 night hotel stay to pick up the cruise there. Probably cost us $2k plus.

My flights were great and the crew on them was lovely especially the London to Barcelona flight as Al & AJ were so amazingly nice. I wish they would be my crew always as they have the best customer service. Sadly both flights were delayed the first one from Vegas was because they clearly loaded the cargo wrong the plane was off balance making us 2 hours late. This made me miss my connection and sadly it was challenging rebooking while I was on the flight. I will never use Kayak again as there was no customer service number or live chat and you rebooked me on a flight 2 days later. I had my mom call BA to change it which she did after spending an hour on hold. This should not be so difficult. My second flight was an hour delayed due to not being able to disconnect the bridge from the plane but I did finally make it home.
