I originally thought I was booking with ANA airlines and didn't see "operated by United" until the day of. I even thought the United check-in update was a scam so ended up checking in 3 hours before the flight, causing separate seating and uncomfortable middle seats.

I originally thought I was booking with ANA airlines and didn't see "operated by United" until the day of. I even thought the United check-in update was a scam so ended up checking in 3 hours before the flight, causing separate seating and uncomfortable middle seats.

Very disappointing. Our flight was delayed for almost 6 hours with the lost time disrupting our travel plans. United should have known that any delay (approximately and hour) triggered a no-fly/work because according to the FAA they had to many flight hours. After the mechanical delay (approximately an hour) we had to wait for a fresh crew change. Seems to me that United could have anticipated this incident. Again, a very disappointing travel experience.

Excellent crew, food and comfort from LA to Narita. Flight from Narita to Manila was just okay, Food and comfort needs to improve. The business class was not comfortable.

Lots of leg room in premium. Departed exactly on time. Friendly crew.

My connecting flight from CTS to Narita was late and I missed my connection. A very nice agent met me when I deplaned and ensured that I caught the next flight back to SFO. Fantastic customer service :)

Cabin Crew was excellent. They took care of everything requested. Flight was good

I didn’t know that my connecting flight from Japan to Hawaii was at a different airport - arrived in Haneda (ticket said Tokyo but didn’t notice the airport name) and had to get my bags and go out of immigration and back in to go to Narita airport 2 hours away. Such a hassle and SOOO confusing and complicated. Check your airports IN ADVANCE and NEVER book if you have to change airports. 40+ years of flying and first time had this. Never again. ANA is great but booking agencies will sell you a connection that you have a good chance of missing - even under the best circumstances.

I was charged $200 for a 2nd checked bag, which is unreasonably high and feels like price gouging. Other than that the experience was excellent.

The ROOM was great. We would love to have it on all of our flights. LOL

I would prefer to fly with Japanese airlines over American ones. They have better food and service overall

Not as good as I expected, I couldn't use the screen to watch movies or anything else because it wasn't 'STEADY' AT ALL, it moved every single time that the passenger who sat on that seat moved, that caused me fell dizzy and nauseous when I tried to use it, so I ended up with only sleeping and eating with no entertainment all my haul flight on premium economy seat, plus the passenger who sat next to me, she just loved to spread her very long hair down on my shoulder, face, arm, sometimes her hair just whacked my face till I really wanted to offer her my hairband!, super annoying 😑 and that my bad experience with that flight.

The flights were on time and the cabin crew were very nice. The only downside was that the food was not good.

Good pilot and crew. No food or beverage on this flight Entertainment is via own device thru plane's wifi.

My plans changed and I tried to cancel or change the flight for credit but was giving the run around and denied . Not great

Excellent service, excellent food and beverage options, plenty of leg room

Checking in as an international flyer is a bit tedious

I was so hungry , from Boston to Tokyo, only 2 big food .

It was okay, short flight so nothing much to comment.

The crew was nice, the food could be better, and at least 2 bathroom stalls were out of service.

The crew was attentive and provided everything I needed. The food in business class was excellent.

Liked the attention and speed when getting wheelchair..........Was assured by phone that my needs would be taken care of and they were with my name.

The seats were spacious and comfortable. Even in basic economy. However, the flight boarded 30 minutes late.

Alaska used to be a top notch airline. With it's growth it is now in line with the big airlines. Not bad, not great.

Great. I did have a little issue getting into the Lounge, which is likely more an American Airlines issue. I did not carry my physical AAdvantage Executive credit card with me on this trip, which Admirals Club membership is a part of the benefits of having this card. The instructions on the AA website and the Citi cards website make it seem like you don't need the physical card, as both sites state you can enter with your boarding pass and driver's license. But both lounges said you were required to present the physical card (and not the digital version, via Apple Pay), as only the physical card says "Admirals Club" on the back.I also do not have a physical Admirals Club membership card, so while both lounges eventually let me in, both denied me entrance initially for this reason.

Everything from the time I booked my flight through to the end when I got home was smooth and wonderful. Service was great, the flight attendants were attentive and there were no outstanding delays.

Delayed and no entertainment? I also forgot my headphones and immediately reported it and have not heard back yet.

The crew was very friendly. Boarding was quick and efficient.

You need categories to note when food and entertainment are not available. Alaska's system would not update flight info on the board for this flight, so there was some confusion after deplaning from the previous flight as to which gate and depart time were accurate for this flight.

we waited for 50 minutes to check a bag and missed a flight. do better.

After a swift boarding we had to wait in the plane for over 40 minutes to take off. The same happened when we landed. Alaska had much more work to do on their timetable

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

it was a very short flight so my expectations were low.

As great a red-eye flight as red-eye flights can be.

Once boarding started it was pretty quick. Food was inedible; cold and salty..

Entertainment kept turning itself off. Gave up on watching a movie.

Both the WIFI and entertainment did not work for 2.5h

Great setup on both flights except the last flight we got condensed dripping all over me in the last 20 mins of the flight

Everything went smoothly — on-time departure and very organized boarding. We pre-ordered vegan meals, which were fine but not especially memorable. We may have had slightly higher expectations given it was a Japanese airline. It felt like a dinner meal than a breakfast. Overall, it was a good flight experience and we would recommend it.

The last 3 hours it was freezing cold in row 56. Multiple people had their winter coats on and were utilizing the blankets provided by the airline. I also did not have easy access to figure out how to book my food allergy and advance for my meals. Most of everything I received was something I couldn't eat. This needs to be made more accessible. Also, I'm 5'10 which is the average height of the American male. I flew from Philadelphia to Toronto and then to Tokyo and the seats were absolutely unbearable. For that long of a flight it is impossible to get comfortable when doing anything. Flights need to have more space and stop prioritizing costs over people.

Was delayed at every point/ connection. Luggages missing for 5days. Had no medications for diabetes and high B/p. when bags where finally delivered on the 30th, the insulin and ozempic were no longer patent, as the ice pack had since dissolved and the authenticity of the med is now questionable, since they must be refrigerated. Please have them refund my bag fees. I should sue them for all the inconveniences caused to me.

The plane was delayed substantially due to a mechanical problem, that being said, the airline was very fair with providing a meal coupon for us. I would rather arrive late on a mechanically sound plane than the alternative. The food served in the plane was just awful, however and I recommend a new catering company.

I waiting for 2 hrs to retrieve my luggage. Didn't get home till 3am.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Flight cancellations, delays, mass confusion and disorganization! That’s Air Canada for you, nothing new. I would have chosen a different airline if it were an option, and Air Canada continues to prove they don’t care about their customers.

This flight with a lot empty place , and I have more room, feeling comfortable.

Snacks were just placed and many people were hungry and unaware they were available. Ran out of water bottles. Attendants not available. Missed entire meal.
