Paid for seat assignments that did not in any way match seats received, and had to upgrade at checkin

Paid for seat assignments that did not in any way match seats received, and had to upgrade at checkin

All was great on flight to Tokyo. The ROOM setup was very comfortable. Definitely will try to do again.

I thought I purchased premium economy but got an economy seating for an expensive airfare from Kayak. Not able to pay extra to upgrade at all

On time, food was great. Didn’t wake me up when they saw me sleeping and as soon as I used the toilet, they came up and asked me if I wanted dinner. Right on!

I was expecting to fly in a Japanese airline because that what I bought, very disappointed finding out the change of airline without any explanation.

Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

No real issues on this flight other than the overhead bins said reserved for premium customers for a large section that was over non-first class seating

The seats are so close to seats in front that you cannot lean forward and reach anything you may have placed or dropped on the floor.

It's no surprise that bigger overhead space would be nice, but they are super convenient and helpful with the baggage claim stuff.

I like the customer service. I was upgraded on flight, so enjoyed the better seat selection

Overall, excellent, including the warmth, friendliness and equanimity of all the employees,

First flight one hour late, return on time. On both flights everybody were just great Seats comfortable. No complaints, just , 2 good flights. Like flying Alaska Airlines.

Plane narrows toward back of flight. Seats small. No snack options. I cookie pack going. 1 pretzel pack on return. No in flight entertainment for long flight.

First time flying on Alaska Airlines. Very good experience. Boarded, landed on time, baggage claim was quick just as they guarantee. When returning home, the nicest person at the check in counter helped with our checked luggage tickets and our wine cases, which were free to check (one per passenger) when you joined their rewards program. Will definitely use this airline again!

We were really impressed with the customer service throughout Alaska Airlines. Every crew member we engaged with were very welcoming and eager to help. I find airline travel to be extremely stressful, but my experience with Alaska Airlines was the complete opposite. We will definitely be booking future flights with Alaska Airlines.

I paid a substantial additional fee to upgrade to Premium Class because I wanted a more comfortable, peaceful flight. Instead, Alaska seated a couple traveling with a 14-month-old lap child directly beside me. The child was loud throughout the flight—screaming, throwing objects, and tossing food around the row. What I paid extra to make relaxing and enjoyable became stressful, cramped, and absolutely miserable. There was nothing “premium” about the experience beyond a few additional inches of legroom. I understand that families and young children need to travel. However, Alaska sells Premium Class as an upgraded experience and charges passengers accordingly. If the airline is going to collect a significant premium for added comfort, it should give customers some meaningful way to protect that investment—whether through better seating options, advance notice, the ability to relocate when seats are available, or a refund when the experience is completely undermined. I would not pay for this upgrade again. It was a waste of money, and I intend to contact Alaska directly to request a refund of the Premium Class upgrade fee.

We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

Second flight in a row where the entertainment system is broken. 5 hour long flight with no entertainment and flight attendants did not seem interested in resolving the matter. Very shocked to be treated this poorly considering I paid for a first class experience and have Diamond Medallion status.

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

Crew was great. Friendly, calm, interesting, happy to be there. That makes a huge difference. Plane was very quiet. Also quite empty so I had three seats to sleep across

The flights were on time- Great service Would have liked more options for food choices.

The brakes on the A220 are sensitive and uncomfortably grabby

The food could be much better. Also very unfortunate that most of business class seats were empty but I could not upgrade.

It was serviceable, nothing special but nothing awful on this leg.

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

Warning- Air Canada makes it almost impossible to get a refund if a flight is cancelled. My flight was cancelled due to a damaged plane. This airline then rebooked me for a later flight. I went on line and tried to navigate their site to rebook to another within my original itinerary and I had thought I had changed it the first time, but since their site is nothing like our sites here in the states, you had to closely look for the links to complete the process. Then came the other problem. Trying to get a $45 refund on check in baggage, that I had paid for one day in advance. I tried calling the airline's customer service. They stated they are unable to process refunds for this. They then referred me to an on line site. This site required you to answer a multitude of drop down questions that are not applicable to a simple flight cancelation. Then right when I think I am done, it asks for an "incident number". I then eventually fly into Vancouver BC International Airport and speak to 3 Air Canada employees. They then tell me they cannot refund me my check in bagge fee. Once again, they refer me to this ridiculous site . They then give me a code to list and tell me to use the airport code, plus the letters AC followed by the flight # to list as an incident #. I tried this and guess what, it failed. Kayak, if you're listening. Something is very ethically wrong with Air Canada's refund process, especially when one of their planes is damaged and a flight is canceled. I have flown for many years, every week for a long time period with many airlines. Please post this so the public can see this accurate assessment of their airline customer service failure.

Great flight attendants, great luggage tracking, pretty good trans-pacific business class setup, food was modest. Only paid WiFi in business class unless you enter an Air Canada member number at the time of booking (e.g., no Star Alliance member number). Vegetarian food was tasty but had no protein. Overall, a good mainstream North American carrier flight experience. Acceptable if the price is right. Otherwise, I might choose an Asian carrier for elevated experience.

It was pretty straight forward, no glitches or hidden costs

The whole plane smelled and felt old. The seats were very uncomfortable. Multiple delays. Extra fees.

For goodness sake, board from the back of the plane to the front and assign overhead space. It would fix everything. Seriously.

Aircraft had technical issues. After 3 hours of trying to resolve, flight was cancelled. Was booked on a flight leaving 12 hours after intended departure. Now on 4 flights instead of 2 and a day late to my destination.

PDX staff was great and we arrived on time in YVR.

Horrible I had a health emergency and couldn’t go Air Canada refused to allow me to reschedule

Really poor travel experience. My first flight was cancelled, which cut my international trip short and threw off my schedule. I will not be flying Air Canada again if I can so help it. The crew and in-flight experience was pleasant and enjoyable but the consistent delays and cancellations are not worth it.

Economy middle seat was so narrow that I could not sit back comfortably with passengers on either side of me. Over the 9-hour flight, with my body slightly twisted most of that time, my previously-healthy left knee became very painful, even though I got up to walk multiple times. The knee is still painful 3 weeks later. Otherwise, it was a nice flight, but I was crippled over my entire vacation.
