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.

It was a partial full flight. But even with a spare seat it was hard to get comfortable More on me being a wide body probably

Our flights using Alaska Airlines went great! All of the flight attendants were very friendly. Big shout out to the pilots for getting us to and from our destinations safely!

I can’t complain. Perhaps passing out headphones, but it was on me to bring my own since I could have used some for my personal device.

I liked only the crew. The flyght was too much fast, faster than it should be, on 20 min faster, but not safer, I experienced on myself astranautic overload from suddenly appearing in the sky and all the vibrations of the turbines, because I had my place at the level of the wings. Pregnant woman should not be seated on the level of the wings with all turbines, pregnant woman should be offered to charge place to seat closer to front or in the back, but not at the level of all the turbines. Vibrations of turbines are not healthy for pregnancy. I hold all the flight my belly in my hands to avoid miscarriage. If it would be longer flying distances, I could have miscarriage with Alaskan airlines.

I didn't have food or use entertainment, so those evaluations are invalid.

I do not feel the priority seating I paid for was was adequate for the cost. there was no difference from coach on any other airline, and it was very uncomfortable

First flights on Alaska Air, and I will go out of my way to fly them whenever I can in the future. An incredible experience, above and beyond any other airline.

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.

The flight crew was amazing. I’m very tall and they moved me to an exit row unsolicited!!! Amazing service.

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.

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

My seat was moved multiple times. I picked out the perfect seats beforehand. I even paid extra money for them. However, I was moved to a middle seat without warning at the last minute. It was like my worst nightmare. But other than that, the actual flight was good. Everything was on time or even early and the flight was smooth.

A220 plane had 5 seats across which is great for couples who can snag the A&C seats. Seat itself is borderline comfortable but still tough on a 5+ hour flight. Overhead bins are small so if you're not in at least boarding group 5, you could be in trouble. No included food service. Non-alcoholic drinks are free but even the most basic snacks are for a charge. Price was reasonable for the only direct SEA-YUL flight. Boarding is efficient even managing passport checks. Worth flying for the direct flight.

The original flight from Boston to Toronto was canceled because of a mechanical failure. I was then scheduled on a flight to go from Boston to Montreal and then Montreal to Toronto. The flight was extremely full and I had to check my carry-on bag. When I actually got on the plane there appeared to be room for my bag. I understand the mechanical failures happen. But it was frustrating that they pestered me to check my bag when I don't believe it was necessary. Additionally, not just with Air Canada, modern airline seats are incredibly uncomfortable. There is considerable research that shows that the shape of them is poor for back health.

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Plenty of room in the exit row. Sat on the plane an hour before taking off.☹️ Landed late and had to wait for gate availability.

Flight was on time early arrival better entertainment good staff.everything was excellent
