Seats are more spacious than other airlines that have you packed like sardines.

I would have appreciated notification that our flight was moved to another gate LAST MINUTE so that we would not have missed it. We got no such notice and had to spend another night to catch an available flight in the morning, which was huge inconvenience. We will never fly Alaska again.

Liked premium seat. Did not like: having to pay for entertainment/wi-fi; having to pay for food; single-aisle; and, only three rest rooms.

The airline was way too cold. We were freezing, I don’t know if that is normal. Overall it was pretty good flight. Always flown Alaska Airlines and I am not changing.

I was sitting in row 31 and felt bad smell coming from the toilets especially when boarding and exiting not much during the flight.

Great. They got us on an earlier flight. Really appreciated that

I had very little legroom and the only food available was really salty

Offer snacks/meals for people with food sensitivities. HAVE TV SCREENS!

Cabin crew very friendly and pleasant. Flight left late but we didn't know why. Alaska Airlines app was not user friendly -- app wouldn't let us upgrade our seats, but no indication if flight was full. We wound up having to call the airline to request an upgrade and we were told none was available. Waste of time. Baggage retrieval was easy.

The boarding gate is literally just an aisle to the concourse. There is no seating and it's shared with several other airlines. It's crowded, hot, and standing-room only. It's difficult to hear gate announcements over the PA system with too many other carriers crammed into a small space. I've enjoyed flying AA in the past on the west coast, but the BNA single gate experience is horrendous! Never again from BNA to SEA with AA.

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Had a broken tray in business class. Crew just shrugged it off.

Everything was great except for the seat. The backrest would not stay in the upright position.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

Crew was not friendly when I went to request a seat change.

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

They lost our luggage and didn’t return it until 15 days AFTER we got back.

food worker strike caused lack of service. I know, not your fault but a bit of a inconvenience.

The staff on the WestJet flight were friendly and helpful. The flight was smooth and we arrived 30 minutes ahead of time.

The on time performance and the ease of boarding are great. The crew were cordial. During landing the pilot made a hard landing with some swerve that was a bit rough but other than that everything else is as smooth as it can be.

Horrible, flight on the way to Vegas was delayed significantly and then on my way back my second flight was cancelled

If they have a tv for movie or map during 5h flight could be better and the food can purchase on flight are ok with that.

We requested 2 wheel chairs upon arrival. On board an attendant told us to remain in our seats until everyone was off the plane. we were in row 11 and thought we would be off early. After all were off, a different attendant said we should leave, and that the chairs were gone. One was available for my friend who had just spent 9 days in hospital but I had to walk quite some distance. Eventually a cart arrived to take us the rest of the way. This was over an hour after our arrival. The staff at the terminal did their best to help us but if we had been allowed off with the other passengers, our ride home would have been an hour earlier.

Our flight experience was great! Flight staff was funny and offered great service. Made record flying time coming home from Vegas after having to wait for planes on the tarmac because of high winds

Seats can use more cushioning, it felt very hard. The snack option could be better

Over all good. I had some issues with trying to buy my seat. The Westjet system kept trying to charge my credit card, without getting the seat. In the end after 5 times being charged, I got my seat.

Not worth the premium paid for the first class ticket

Fine. Though no food or entertainment so the survey needs to be updated with those options.

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

Standard flight experience, but there is only power at the seat to row 20 on the aircraft, on my initial check in it did not say that was the case

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

The ride was good but no food ot entertainment hence, it was just over an hour flight.

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

No snacks served! Seating in the kast row in uncomfortable.

By in large it was a good experience. The flight crew was great and that's the most important to me. Boarding was fine.

There was a mistake with the first name we only discovered at security. Air canada was unable to correct it to match then passport since it was booked through an agency. The agency could not correct it either since they need at least two hours to do that. We could not fly and lost a bunch of money. Learned my lesson about kayak.

My flight got canceled. Then AC rebooked me to a next day flight. No compensation no apology. It almost messed up my entire trip and schedule. However, all the unexpepected seems routine and ordinary to AC, so customers need to get used to.

The food was horrible the flying attendance hardly made any checks and the seats were very tied ..

I love air Canada. The staff is so helpful and friendly and attentive. I paid for extra room but chose a ser near a person who took up a lot of space which gave me less space than regular economy, I was sad I did that!

For such a long flight they should offer tea or coffee in between two meals.

No seat assignment . Last on board . Though I would not receive any boarding pass

last minute was rebooked. This rebooking made me miss my connection, added a stop in my itinerary without my approval, and had me arriving 10 hours later to my destination...for a delay that was 2 hours. To boot, my final flight from London to Athens booked me in a middle seat, where I originally booked all aisle seats. This was incredibly uncomfortable for a 24 hour journey and made me incredibly upset.

Did not appreciate “hidden fees” to check a bag for international flight and purchase a seat to be next to my spouse. Won’t choose this airline again.

The flight left over 2 hours late and caused me to miss my connecting flight. Consequently, I missed my cruise ship out of Barcelona. The cost associated with this miss was as follows: Airfare to Sicily Italy to get on the ship TWO days late - $232.30 Taxi from Airport to hotel $35 Dinner at hotel $38 Hotel in Barcelona - $208 Taxi from Sicily to hotel $70 Hotel in Sicily - $148 Prorated time missed on cruise $ 1,143

No meal. Flight crew was wonderful, happily finding me storage for my guitar. THANK YOU!!!
