The flight was delayed and food was averiage - only sandwich. The flight attendants were good and gave outstanding customer service 👍🏼

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....

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 .

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.

The crew spoke Chinese to every Asian person. I even did not understand anything. So rude. If they don't know passengers’s nationality, they have to speak a common language in English. They lost my luggage. I didn't have it now. I don't know where is my luggage. They lost it. So terrible airline. I will never use it again.

The crew was great. There was no wifi The cabin temperature got very hot Seat was uncomfortable

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.

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 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

Unlimited drinks and snacks on this long flight. Very courteous Korean staff !!!

Great crew, decent food Charging plugs were broken on both seats next to me. Only the USB port was available, and that charges, very, very slowly. Seat was also broken, it would not lock into position when reclining.

They moved my seat without my consent and they won’t refund the money I spent on it. I paid for a front row aisle seat and they moved me to a center seat in the last row of premium economy. They were very rude about everything and nothing like Singapore Airlines or Korean Airways which I flown before.

I had a hard time checking in as my first and middle names lacked a space. The vendor spent a long time fixing it with the JAL. This should not have been a problem. Check in at ohare was good as Regina was very helpful and kind.

It was just a short flight. The crew was nice. No major issue.

It was good overall. What I liked most was the restrooms. Compared to other airlines, the restrooms seem larger and look clean. The seats also look clean. The attendants are nice, except one time during the flight. I was sitting on aisle and a man sitting window. He asked an attendant for a snack. She told him to go ahead and get some snack from the section with food storage (I am not sure how it is called). So, I had to get up to let him get out from his seat. Why she did not bring him some snacks so that I would not have to move, I do not know... I was kind of surprised how inconsiderate the attendant was.

Horrible like always, flight was supposed to be at 11:40am, we ended up getting a different airplane at 3:25pm.

I fell asleep, and the crew kindly left some snacks for me

Seats in "Premium Economy" were noticeably more comfortable than those in "Economy" and worth the price. My only reservation is that the foot rest did not go higher up. If it did, it would have made the seat much more comfortable.

The plane was dirty, there was trash in the seat pocket in front of me.

Particularly meals were great. Service’s were excellent as usual. .

Attentive crew, great service with regular rounds of drinks and trash collecting. Only complaint is the food, which was mediocre.

No beverage/snack service without any explanation or reason. Late boarding and delayed flight.

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

I'm 6' 2" and even in economy plenty of leg room

Horrible experience. Delta delayed the flight to 11pm which happens. Apparently the pilots were there but we were waiting for flight attendants to arrive from Detroit and they were delayed. They could have made arrangements but that’s fine. What was truly horrible was that at 10:50pm the pilot comes out and says the flight will be cancelled but hasn’t been cancelled yet in the system. It’s being cancelled because the pilots have timed out. As soon as that plane got delayed past 10:50pm delta knew it couldn’t fly. Yet they made us wait around for hours. When the flight finally got cancelled all the area hotels were booked and flights for the next day were unavailable until midday. All I wanted was to spend one day with my family before needing to fly abroad on another delta flight. That will be my last flight with them. I’ll take my 800k miles flown and annual spend to an airline that isn’t so thoughtless.

THI IS THE 3RD CONSECUTIVE FLIGHT FROM ORD TO MSP THAT HAS BEEN DELAYED 2+ HOURS. CRAZY

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

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.

All good. Flight crew was super friendly at the end of a long day

The food in first class has taken a big downturn

Flight was fine. Just delays leaving due to mechanical issues. But flight crew were kind and professional. Seats were spacious. American doesn't need to have 9 groups for boarding.

Both departure and return flights had mechanical delays. Their planes are antiquated resulting in a two hour flight taking almost four hours to complete.

Crew were helpful, pilot kept us informed about turbulence, snack choice was awesome!

It was one of the worst I have ever had. The plane was over booked, and I did not have a seat. When I questioned why because I had booked this weeks in advance. I was brushed off to be advised they are trying to find someone to give up their seat. Only to be advised I would be boarding last. I had priority boarding in group 1-4. When I asked why I had to be last because that is not what I paid for I was advised it doesn't matter you will get a seat. The ticket person was very rude and unprofessional. The gate changed several times and it was going from one area to another area far away from where we were at. I feel like I should have been compensated in some kind of way because of the way I was treated. The ticket agent acted like it was my fault that the plane was over booked. Not one time was I apologized to for this inconvenience.

We did not fly on American Airlines from Chicago to London. We were rebooked on British Airways (by American Airlines) and our luggage was left behind. A full day delay and lost luggage.

I have posted the comments in the first flight leg.

First class snacks - stewardess gave out multiples to everyone until there was almost no selection left when she got back to me last in first class cabin. Nothing left that I would eat.

My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.
