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.

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

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.

Westjet requires you to check in on your cellular. This takes about 5 minutes compared to when there were live humans doing check in. Ultimately the machine meant to spit out boarding passes and baggage tag went into the pinwheel of death. I also got a sternly worded email telling me I was ineligible to check bags, even though I’d checked one. The dude who eventually checked me in barely grunted at me and didn’t give me a baggage check. Had my luggage gone missing, I don’t know how it would have gone. And then there is the chaos as people jammed huge carry ons into small overhead bins. Westjet is a cattle car.

WestJet ran out of dinner meals on a transatlantic flight. Crappy to have a bun and a bit of lettuce for food on a long and not inexpensive flight. Flight staff did not look for options to resolve.

Delayed 2 days in London England - very poor communication from Westjet

The Priority check in in Toronto rivalled the poorest I've experienced. The young woman at the desk (7:30 AM, YYZ) was unfriendly and abrupt, behaving as though we were interrupting her day. Her inch long fingernails said it all....I really don't belong here. Other than that, WestJet personnel provided a good travel experience, especially in flight. I must say that the repeated announcements about the cabin being full and how folks should gate check their bags became tedious. WestJet should just offer free checked luggage and charge for carry on suitcases. It would save a lot of time and the voices of the gate agents.

Wish there was an option to book a fellow traveler who is not necessarily paying on the same booking. Then the airline could consider placing us together. It was a long flight to be separated from travel buddy. The first meal, a luncheon I think was ok with warmish pasta and a tiny salad. The second meal, a midnight snack (hard to say because of the time change) was really awful pizza fold-ups, and no option for folks who cannot eat cheese.

It was a 35 minutes flight. Didn't expect much. You should add a 'not applicable' option to your survey.

The back seats are crowded and at times uncomfortable. I guess that’s part of the price of paying less for a seat.

My journey from Rome to Seattle contains two parts, first from Rome to YYC then transfer YYC to Seattle. First part from Rome to YYC was wonderful. Fly on times, easy boarding and comfortable seating and good meals. Second from YYC to Seattle is terrible, delayed three times before boarding. No meal, no water, no entertainment. Landed in some corner of airport , walking in bitter cold night and taking the bus. My friend told me that Westjet is the best airline in Canada, I doubt it

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

Adequate though food was not great and no alcohol abailable

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

Missed this flight due to the first AA flight delay

Horrible delays and confusion at all Air Canada counters. Flight was delayed well over 6 hours with little to no communication. Was o my offered a $15 food voucher and $200 Air Canada voucher—-neither of which did I need or have desire to use. Will never fly this airline again.

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.

Prepaid for my seat selection over a month in advance only to be told when I arrive at the airport that the plane has changed and no pre-selected seats would be honored and refunds would not be issued immediately. Was forced to separate from my traveling companion Air Canada. Unsurprisingly was no assistance in this whatsoever. Plane. We got switched on to also has no entertainment options available

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

Excellent host on board. Not so friendly check-in staff. Older plane with no food or entertainment due to short flight. Friendly captain and crew.

It took 66 hours to get from Seattle to Tel Aviv. As a minor, I was left for more than 12 hours in Toronto and Frankfurt without hotel and food vouchers. It took 5 layovers. It was insane and not okay

Flew SEA-CA, then CA-NRT. First flight was short but very uncomfortable, dirty, and had very small overhead storage space. The seats and fans were not cleaned and had visible dirt on them. Second flight was perfect.

Lost my bag. My first ever flight with them that they forced me to gate check my bag on, due to them having a 30 year old plane with small carry on bins, and they lost my bag. Never again.

I liked Seattle but nothing air Canada did there was any good at all neither was kayak as when I purchased my flights the price I purchased at was not what kayak charged to my card and there has been no responses to my emails ....

Glad to see the staff of Air Canada take preference in protecting their customers from unruly passengers before they board. Well done
