They forced me to check a bag. When Kayak sold me these tickets I was not informed of carry on baggage weight limits.

They forced me to check a bag. When Kayak sold me these tickets I was not informed of carry on baggage weight limits.

Great food on both legs and fast customer service from the stewardesses....

The food was great; the attendants were pleasant. Waiting to onboard felt stressful, as passengers who had connecting flights at SEA had to be verified again for two things before getting a real boarding pass: passport and carry-on luggage weight. The boarding pass issued by another airline (i.e., the first leg of my trip) did not count. The S terminal at SEA was barren, with lots of sensory overloads because every airline was repeatedly broadcasting long lists of names of passengers who had not gone through that verification process. The carry-on luggage weight check seemed futile to me. I saw a woman who opened her over-weight suitcase to move some items into her shoulder bag. She still boarded with two huge bags with her. I assume this check is an endeavor of ensuring fairness of the overhead bin space or optimizing fuel efficiency when gas price is through the roof, but I don't know if either goal is achieved. Nonetheless I respect the crew's dedication to the SOP.

Food tasted like the meat had freezer burn. Another thing all of our 4 check baggage was left somewhere and my oral medication for my diabetes was left in one of the lost luggage..most of the flight attendants did not know how to communicate in English.. the trip was a total nightmare

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

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

I appreciate the email reminders for online check-in which made my entry to the lines less stressful. The flight was on schedule and on time. The baording staff were proactively helpful and approachable. The airplane inflight food, entertainment and comfies as well as provisions are excellent even in the economy seating. The airline transfer was smooth and easy! Luggage safe and intact! Thank you EVA airline for making my trip a reliable safe and comfortable experience.

On time service. Seat comfort and the crew service very good .

Only one Hindi movie from LA to Taipei and same movie from Taipei to Singapore Why we call it entertainment when I have to watch one movie for 18 hours flying ?

Eva air is a good airline. The seats on the way to Taipei could have certainly been more comfortable, but all in all it was a pretty good experience.

Very easy to use and convenient, you can perform any action within the same portal

Okay considering we had weather delays which the Pilot notified us of immediately!

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

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

The staff was frielndly. The plane was terrible, it was too small and should be decommissioned. There were no back seat screens at all. The only beverages we had a choice from was coffee, tea or water. The only bathroom in the back was behind the flight attendant's jump seat and wasn't working. And I literally felt like I was sitting on top of the guy next to me. It was terribly hot in the plane and we had to sit on the tarmac in Chicago for 1/2 hour due to congestion in Mpls. Wouldn't they have know that before they even boarded us so that we could have sat in comfort in the terminal?

This was one of the worst flights I’ve been on in years. I upgraded to comfort and had such an uncomfortable experience. The person next to me was oversized - which I understand - however, they took up their space and mine. I could only use about 50% of my seat space to not be physically touching this person the entire flight and there was no spatial awareness. I also could not use the seat outlet because their body was obstructing it. It was very inconvenient. Their body kept touching me repeatedly during the flight and I felt very uncomfortable. To pay more for an upgraded space and then not even being able to use it was highly disappointing.

It was very cold because the air conditioner was on high power, and my son got sick.

Horrible. Flight ORD to CGH was okay, but Paris was a nightmare. Old planes, delays, involuntary downgrades, broken planes, terrible communication. CGH to CPT was my worst flight ever.

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Delta airlines charge $ 30,oo US DOLLARS for the check in for a suitcase in the baggage hold

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Despite the crew's rough day, they were all very focused and friendly. The flight was too short for a meal, so no rating on that. Re. the AA app. It still isn't ready for prime time. AA works with Cathy Pacific for international flights to LA and the Aa jump to PHX. But the AA app can't find my trip and this can be problematic with flight delays and regatings at LAX.

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.

Everything was fine and I have no complaints or things to note.

Overall, it was ok. However, the food was very sub-par.

The economy seats are much indeed roomier. Meals needs improvement.

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

From Chicago to Hong Kong was great., but from Hong Kong to manila we had hard time looking for the gate of our connecting flight. There wasn’t hardly any sign.

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

The coffee in Premium economy and economy is terrible. That's it. Everything else is great

We were forced to eat vegetarian food because non veg food ran out. The breakfast was mediocre.

My original flight was cancelled and that affected my trip and my plans and I got no compensation and customer service was hard to reach as well

The kid in the middle seat kicked me almost the whole flight, almost kicked my hot tea off my tray. The flight was delayed due to the first plane not being able to be de-iced in July! We had to get a new plane. Now I drive 3 hours back to Edmonton because direct flights from PVR were way to expensive

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Know that the movies that you are going to be offered are the oldest be rated movies they could possibly get. They may have one or two new movies that they keep advertising but when you’re flying 15 hours, there is nothing to see past the first new movie.

Agents at gate were not immediately available to solve problems and once they did they didn’t fix all the fight connections

It was perfect! United Airlines staff was extremely caring, super friendly and professional

Food is very bad and entertint not too many options ... flight attendet service is not good

For a 17 hour flight, they kept us well feed. The music selection could be better curated. The entertainment selection was about what is expected. The crew was fantastic.

I forgot to pre order gluten free on a 16 hour flight and I am pretty sure the crew raided their own lunches and first class to keep me fed.

The code sharing reservation with United was messed up requiring extra trip to airport to fix. Air Canada customer service 2.5 hours on hold and resolved nothing.

I'm 6'8" (2.03m) so more legroom would alwqys be appreciated, especially on long international flights. The food choices were underwhelming.

Didn’t make it on the flight. Delayed then had to be rebooked, which in turn had me waiting at the airport for another 8 hours before next flight

the check-in lady at ORD was extremely rude and unprofessional. very disappointed as it was supposed to be a celebration for my wife's birthday and it really put a damper on things. if i wanted to be treated like trash, i would have flown Economy! (as opposed to business class)

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.
