Their was $200 charge for 2nd luggage, airplane very new and flight smooth. Flight time seem faster then Asian stoping Korea then china.

Delays, plane transfer due to malfunction, no entertainment, limited beverage service.

Seat was broken. Check in was not possible until we reached the gate, by then we were separated.

The food was not great; but I don’t expect much from airline food. However, the staff was incredible! I had gotten to the gate when I realized I had left my computer at the security checkpoint! I told a staff member and she said, “well, you will miss this flight if you go back to get it” It was a long way from the gate. I asked if I might get on the next flight. She sent for another staff member, and he took me to the gate desk. He found an open seat, and said,”okay, go run to get your computer, I will get you a new boarding pass.” I rran back, retrieved my computer, and returned to the gate. It was closed, but I found the gate nearby where the next ANA flight was leaving. Another staff member was ready for me, and printed me a new pass, and even made sure I still had an aisle seat that I requested! I got in line and continued my trip. These people are amazing, helpful, and friendly. My trip could have been ruined, or postponed at a great expense, but they saved the day! 5 stars!!!!

Best service! Food was Japanese fine dining and they even sang happy birthday to me since it was my birthday halfway through the flight. Bed was comfortable and cabin was quiet.

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 :)

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I normally love Korean Air, but this trip was not great. We boarded the plan and were settling into our seats. My son and I use these leg swings and we used it on the trip over to Cambodia, but on the way back the flight attendant very rudely told us we could not use it and that it was against regulations. I asked to see the regulation, but never saw it. The food on this trip was horrible as well, Even my son's kids meal was disgusting so we didn't eat anything on the flight. Thankfully we brought snacks. Entertainment - what happened to the games?

Plane took off on time and I had the whole row to myself!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

our Flight attendant Tina was great and she made such a difference in a very disappointing "First Class" experience. Seats weren't much larger than the ones in coach, there were NO FOOTRESTS, one of the reasons we paid a premium price for a 6 hour flight. The charger for the phones didn't work in our row so I had to plug it into the row behind us and there was no free wifi, so my wife and I paid for it and it was mediocre at best. Lastly there were no screens to watch movies, There was nothing 'first class" about this Alaska Airline experience , except for Tina! They just charged a lot more money for what on other airlines would qualify for the improved economy class. Very, very disappointed.

Departing flight for our weekend trip was cancelled due to weather which meant our return flight was useless. The whole thing was difficult to get support through but Alaska did recover and was able to reimburse us for the flights yesterday. For some reason, Kayak was not kept in the loop, adding to the confusion.

i canceled my return flight package with Alaska Airlines. Customer Service was excellent and assisted me to cancelled both of our reservations and returned the payment in full. that is excellent service and understanding and empathy of the customers' needs. i like Alaska Airlines and recommend AS to everyone.

They changed the flight time from 4:00 to 1:50. We missed the flight because we did not know. We were not entitled to any sort of refund.

After landing in Seattle, 3 hours waiting to find parking space do to driving problems. Very uncomfortable.

My only complaint was how far it was from plane to baggage claim

Snacks for our toddler could have been better, front the standpoint of variety but that’s not any different from other airlines.

The flight was delayed by 2 hours for “routine maintenance”and because of that I arrived much later iso my Uber ride home was $100 when it’s normally $50.

The airport crew and on board experience was fine. The problem with Alaska air is that there is zero customer service over the phone when you’re trying to buy your ticket or change anything.

More or less, this seemed like a mismanaged group of great people who would crush at this job, if only they were given the resources to do so.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Both my flight where delayed Had 25min to make it to my transfer flight

Everything was on time and service on the flight was great!

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .

The 777’s economy seat’s legroom was more tolerable than expected. I appreciate the reclining mechanism which slides the seat forward to minimize cannibalizing the space behind. The food was terrible: very salty.

The travel company that you have on your site did me so wrong. I don’t know how it happened, but they put my son‘s name on my plane ticket flying to Vietnam. Along with his birthday. They would not have let me fly from Fort Myers to Ho Chi Minh City. I don’t think that I can ever use your service again. I typed my information into the browser along with my passport number and four days before I’m leaving I have to quickly search another ticket to fly out here.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

It’s always a great time flying with united airlines.

Good flight. Efficient boarding and competent flight crew. No problems until we arrived at our destination gate. We were early so there was an aircraft at the gate that had to move before we could pull in. Then, due to the type of aircraft we flew, the cabin door could not be opened until some luggage from the cargo bay was offloaded to preserve center of gravity characteristics. So, that further delayed deplaning. Despite being 20 minutes early on landing, we ended up being 5 to 10 minutes late after all the delays.

Departed Palm Springs over an hour late because there’s only one gate, and it has always delayed by the arriving and departing flight to Toronto and the arriving flight from Vancouver.

I checked a bag and there was only one agent to assist all customers with any issues.

I want to thank Carlos at the Miami AC desk - he was amazing and went over and above to help us out. Thank you Carlos and all the best to you!!! You made our faith in AC feel great! Sincerely, David Cubitt

Flight was canceled due to mechanical issues. After a considerable wait in the queue, Air Canada customer service was very helpful to get us on another flight. I am disappointed to report our rescheduled flight is for three days from now. Three days of extra expenses and inconvenience is unacceptable.

Extremely disappointing. My original Denver–Vancouver–Bangkok itinerary was cancelled due to a crewing issue. I was not proactively supported and had to drive back home after already reaching the airport. Communication was poor throughout, and attempts to contact customer service resulted in being on hold for nearly three hours without reaching anyone. Instead of being rebooked on the same direct routing the following day, I was rerouted onto a much longer itinerary via multiple cities and airlines, which resulted in arriving approximately 30 hours later than scheduled. At Denver airport, there was no visible Air Canada representative available to properly assist. Ground staff offered no real support beyond directing passengers to a phone number. There was no clear communication, no ownership, and no meaningful customer care during a major disruption. The final journey involved three flights instead of the original two, significantly increasing travel time and stress. Overall, the handling of the cancellation and lack of customer support was unacceptable. What could have been better? Clear communication during the cancellation Accessible customer service (phone support that actually answers) Proper in-person assistance at the airport Rebooking onto a comparable routing rather than a significantly longer one

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.
