Mostly good. Delayed which in my experience so far happens often with Alaska Airlines. Thank you.

Excellent overall, but had to wait 30 months while taxiing. In fact, I’m still on the plane now!

We received a check-in reminder the day before the flight, and it listed the flight at a later time. Correct flight number, same seats, etc. for 3 hours later. I called the airline to confirm and they had no record of the email. The info was wrong, and we would have missed our flight if we'd assumed it was correct. I want to know where/how we received this incorrect info.

Middle seat, elbow wars. I cannot understand why they load the front of the plane first. You would think it would be more efficient to load the back to the front. I believe it is. And it needs to be changed.

Very satisfied with the trip, using Kayak and Alaska Airlines.

Paid extra $230 to check frozen fish on arrival to LAX. I was told my bags miss my flight and we’re gonna be on the next flight that comes in two hours later regrettably my family was here to pick me up so I had to drive all the way home to drop them off then turn around and come back if I had waited on Alaska to deliver them they told me that they would be delivered in 4 to 6 hours after 8 AM tomorrow which would’ve caused the fish to spoil stink and be a lost cause they would’ve put about $2500 worth of fish down the drain very unhappy with Alaska Airlines for not getting my baggage here, especially since I had to pay for the extra service

How can we get assigned an A seat when booking a flight ?

I was very pleased with this trip from Anchorage to Seattle and Seattle to Billings. Wheelchair assistance was rendered and gratefully accepted. Unlike my outbound flights to Seattle I did not have long, painful walks on a bad knee to get to airport gates. My thanks to the Alaska staff.

No issues at all other than the seats. Of all the airlines I've flown on in my life (this was my first with Alaska Airlines), these were significantly the most uncomfortable seats I've had - more so than Spirit Airlines. I'm a relatively young guy and mostly fit but oof, i was aching in muscles I didn't even know I had. Not sure if the seats are standard for the plane (if it even works like that) or if the choice to use cardboard as cushion and 90 degree angle back rests was a decision, but it wouldn't honestly make me think twice about flying with them again. Other than that - perfect flight. It was quick, crew was nice, ride was smooth so all things considered I appreciate the last minute availability offered after a sudden relocation on my part.

Short flight was fine, but no entertainment and bathrooms broken.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

The flight crew was friendly. I tried to adjust my seat online ahead of time but no option existed without additional fees. My friend asked at the gate about a seat change and was able to make it happen. That was great! The flight crew moved a very tall gentleman and his companion which allowed us to have more space which was nice. Overall, good experience. Appreciated the blanket and pillow.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

Our seats were comfortable with adequate room to stretch out and recline. The food was tasty and served it just the right intervals. Our flight attendant was extra attentive and friendly. Flight arrived early. And the most turbulence. Overall that’s good and experience for an 11 hour flight as can be hoped for

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

It was beautiful easy and smooth experience. Thank you. Will definitely get Delta for my next travel.

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. 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

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

Very nice and clean plane. Transit time between flights was tight though

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight

leg space better than expected. two washrooms for one plane isn't enough.

There was a man who was very rude at boarding. On the other hand personal bag measuring box is too small compared to USA airlines,

A little better seat cushions would be appreciated. Crews were all good.

The process and flight were both smooth and trouble free

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

my carry-on bag was delayed and I did not receive it until the day of my return at the airport. This delay caused me significant inconvenience, as I did not have access to my personal belongings for the duration of my trip. I had expected to rely on my carry-on items, and being without them negatively impacted my travel experience.

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

Worst check in and bag drop off experience. Staff were incredibly rude given that it’s the WestJet system that is faulty.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

We were happy with our experience. The price for tickets was much less than Delta and we actually took off and landed a little ahead of scheduled times.

Seat back entertainment monitors would be nice. We did enjoy the In-Flight WiFi.

No food to provide, they forgot that, in some cases, people stay at the airport for hours without food. Now, to provide them with food, they have to ask them to pay, because some don't have money. That way, they can't eat.

After a long flight from Tokyo, our connecting flight home was canceled due to “maintenance” while we were on our layover in Toronto. Very frustrating to close out our honeymoon, although I’m sure others had it even worse during last week’s strike. Air Canada staff at Pearson Airport are the one thing that kept me remotely at peace during this — they were very helpful and deserve a lot of props. But I would not fly Air Canada again.

I had wonderful wheelchair assistance through the Montreal airport onto the flight. Air Canada was excellent in this both at the Fredericton airport and the Montreal one where an attendant helped us through customs as well as transport and baggage security.

Horrible flight cancelled had to buy another very expensive ticket

Flight was cancelled last minute due to Air Canada strike leaving us stranded and having to stressfully find a way home that cost hundreds of dollars in excess cost added to the trip. Having just experienced our mother's funeral service, this was not a good way to end our trip.

Air Canada marooned me in Canada with no way back home during my summer vacation. I had to buy a last minute flight ticket for over $500 to make it back home. I have their credit card and have flown them for years. Never again.

Flight was cancelled last minute. Had to scramble and purchase a $2000 flight through a separate airlines. Stuck in Toronto two extra days. Missed my first two days on a new job. Had to rent a car for an additional two days. Scrambled to fins a place to live those extra two days. Spent a ton of extra money and lost a lot of money, as well as made a poor impression at work. Difficult difficult difficult

Terrible, return flight was cancelled a night before the flight was scheduled to depart and I was notified by an email and an automated message on their phone line. I’ll never book Air Canada again

Could not understand what the attendant was saying during his announcements.

Biggest problem for me is that I am Star Alliance Gold and they were not able to give me access to to Maple Lounge because of some computer glitch . It was management by information system. She could clearly see my status and still would not give me access because the computer woudl not let her. She should have override that be attentive to a customer and figure rhat out later
