Amazing customer service. BUT!! It would be nice if the flight attendants SMILE a little more, I know they are doing their job, but it is importantly to smile back and be warm to passengers. Nobody is trying to hit on them, it’s just being polite. So, please Taiwanese flight attendants: SMILE MORE WHEN YOU INTERACT WITH PAYING CUSTOMERS

It was easy going check in was easy and pretty fast entertainment was up to date on movies and food was ok

Premium Economy seats were more comfortable than other airlines I have recently been on. Great staff. Food was unremarkable.

From checking at the airport to end of flights, attentive and caring personnel, comfortable seating, great food. I plan on using EVA again. Thank you, all.

Very nice, I feel I got good value for the price.

The soft service on EVA was superb from the quick and attentive flight attendants, to the turn down service, and excellent food. This all made my 11 hour flight very comfortable and relaxing.

Amazing one of the best airlines i have ever traveled with. I live with medical issues called psoriatic arthritis and was in pain on the flight. The flight crew made sure I had fresh ice pack ever hour. Going above an beyond with service and care ⭐️⭐️⭐️⭐️⭐️.

Certain flight crew member were rude and short with me when I asked questions.

We were very impressed with the modern plane its amenities, as well as the services of flight attendants.

The crew very accommodating and food too is good. Keep up the good work

Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Never had a flight delay issue with Korean Air, that's why I always go with this airline.

Flight crew were very attentive and made this trip a pleasure. Plus the fact that this our first time flying business class.

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.

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

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?

This was an amazing flight. The crew was great. The service was great. The food provided was great.

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The WiFi was not working. That made for a long flight.

With Aeromexico it ended up good but with Delta it was bad because we did everything through Delta... Showed up at the Delta terminal... It was the wrong place! Nothing ever told us to go to the Aeromexico terminal. It said "in partnership with Aeromexico" but I was never instructed to check in with them or go to their terminal. We had to haul @$$ running through the airport and almost didn't make it thanks to this poor communication. 👎🏽

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Stop changing gates. Stop cancelling flights Stop moving my seat.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

Very bad Instead 22 hour it take me more that 35 hour to arrive from Los Angeles to Phuket and they changed my flight in Hong Kong to Shanghai china and in order to get my bag I was forced to vet china visa entrry

There could have been more options on the entertainment section Nothing was available for non English speaking passengers

Crew was very good, but could have checked on us when meals were not being served also.

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Flight delayed first from bad weather, then after boarding there was a problem with the plane. We had to get off and onto another plane...connections were missed and the trip took an additional 10 hours!! Pre-paid seatting was not honored due ro last minute carrier changes. Most of the trip was on Japan Airline.

Cramped, hot and the plane was grubby. Also the plane was an hour late and it took an hour to get my luggage once I got to LAX.

Flight from Hong Kong to LAX was late, the plane was grubby, overcrowded and hot. I recently flew Starlux and that was a MUCH better experience.

The crew, pilots and flight attendants were all amazing. What could be better is reinforcing that seats cannot be reclined at departure and landing. I had a person seated in front of me who had her seat all the way inclined, including during take-off - after the crew asked her to seat upright. Cathay Pacific should reinforce this safety request and perhaps penalize those who don't follow it. I felt very unsafe with this person limiting my space and perhaps putting my life in danger in the "unlikely" case of an emergency.

The bed was alright in business class. Food variety and quality were not up to the mark compared to the business class airfare.

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.

Short flight. Everything was fine except the flight was delayed twice for a total of an hour.

There labor disputes cancelled my flight less than 24 hours before my boarding time but there customer service/website was easy enough to navigate and they rebooked me for no upcharge.

Very bad, flight was cancelled due to strike and staff was unable to rebook us

Flight was delayed by 1.5hrs. Once inside, people had their small handbags on the storage. The crew (male guy) was not helpful in making some space in the storage. Instead, he asked few bags to be checked-in and it was not a great experience. No attempt to help but just followed the things with a straight face. People had their literally small bags and he wouldnt not move from one storage to another even if there was space and would not let us do i as well. Once flight was on, they ran out of Orange juice, really running out of orange juice when the temp were 32.degrees outside. didnt made the sense. Onasking for a extra snack, he made a face as if he was giving me out of his pocket. if the flight was delayed, there could have an attempt to provide something extra incase people did asked.

Abandoned me in hallway in a wheelchair… which I asked for because I sprained my back. After waiting in the hallway, I decided to walk the rest of the way since someone respecting me up.. My experience with the united was totally the opposite. Wheelchair access, propped swift and save me a lot of grief. Air Canada totally disorganized.

Terrible confusion btw air Canada and United. Wasn’t able to change ticket because I had purchased on kayak. Rethinking booking tickets on this site, and will try to avoid United and aircanada going forward.
