My flight was amazing smooth and the attendants were so friendly and nice

Crew are excellent. Food was good generally. Seats are small and there isn’t much leg room. Overhead bins are very small.

What could have been better, was we were delayed from takeoff for two hours. Initially we were informed that we were delayed for refueling. Then we taxied out on the tarmac, then just waited there for a long time, with no explanation of the delay. Were we just waiting on takeoff clearance or was there some other reason for the delay? The pilot, nor none of the crew informed us passengers. That was not good customer service. That needs to be improved, whenever a delay, inform the passengers for the reason.

More seat space More bathrooms Charging outlets Plane was old

This flight was long and I am so thankful I had a seat in the back of the plane. As I usually must get up and stretch every hour . The crew were probably the most friendly I have flown with. Thanks and I will book again with Eva air. Food was ok too.

It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

I love EVA airline, but the KAYAK website for not in emergency, urgency and personal issues. For instance, on January 5/2026 with already booked the flight, I have a 15 hours of delay between airport when booked before as my choice. But if I want to go back home (U.S) early, then I have to contact the KAYAK office at I was in other country without phone service and nothing that EVA can do for me. Even I offered to pay more to change from another flight to go to the U.S early, not wasting at15 hours of delay, but EVA could not help me until I call KAYAK at an Island of nation. No office of KAYAK from any nation and times of difference in the world. However, everything and everyone is the best. Therefore, please KAYAK making much more easy for both the airline and passenger in some issues at the middle of nowhere in some country when no need to call KAYAK for some emergency, urgency, sick, etc or personal reference. Please, please, please no need to call KAYAK office for any changes of flights from urgency or private.

My seat arrangement was good with Eva Air. The toilet sanitary was good ( hand wash, face moist spraying, fresh air spray, hair moisturizer). But the Asian movie selection was not great at all.

Don’t preorder the diabetic meal if you don’t have to. Whoever creates those meals thinks everyone loves fish, and hates seasoning. In a world where we can find diabetic friendly candy and low card bread, it’s surprising that places are still serving flavorless gelatin and rice cakes. Boarding in Taipei was chaos. They tried to form a line but didn’t manage it. So once the gate was opened, the line didn’t matter and everyone just mobbed to the front.

Excess baggage fees are outrageous ($250 per bag). Flight crew and planes are nice.

The seats were broken for several of us on this flight not to mention dirty. Quite unacceptable for the price point and expectation level. The meat was so hard it could hardly be cut so terribly unappealing. The united lungs in SFO was dirty and the bathroom conditions were down right disgusting. Nothing about this experience makes me want to book with United again. Our experiences with business class on Lufthansa and British Airways far out perform United in comparison. Truly disappointing!

It was good. The crew was efficient, food was good

They did not get back tickets in time about flight varification so i had to purchase another one way ticket to get home soxas rocnot Risk being unable to return home.

Food looked great but did not taste all that good.

Everything about the flight was good or very good. The only bummer was that there was a 2 hour delay and that's not the fault of the airlines but it still takes away from the whole experience. The most amazing thing was that our bags got to baggage claim in record time! That was excellent!

Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.

Vegetarian options were not that great. However, the crew and service was awesome

The food was not great and the seats you need a little bit more space to put your things down around you: the blankets and toiletry bag were good. Flight was on time and bags etc no issues

Entertainment was good , comfort on airplane easy hoarding food and drinks was good and a friendly and good service of flight staff

The plane was very clean and the crew was very nice.

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

I have been flying with JAL a few times, crews service, food, overall comfort even with economy, I would rate it the top three airlines. None of any American carriers can provide such excellent service.

service was excellent. crew very polite, courteous, and good service especially to passengers like me who is a wheelchair passenger

First of all it’s an American Airline flight not JAL as advertised. Code share is deceiving. Seats are uncomfortable. Stewards in our section were not friendly, felt rude at times.

Lovely flight attendants comfort in Economy Premium. Very attentive and kind I would choose JAL again for sure!

I enjoy flying American airlines. I tried to book American airline when I’m flying most places.

After boarding it was fine. Premium economy was not available for one long leg. Economy was very uncomfortable. They need to fix these issues. Planes are old. It gets more and more dangerous due to fatigue of plane parts. They need to upgrade before something goes wrong with the plane. Hazardous. Hari S Doss

Nice amount of space in economy seat. Very attentive attendants that allowed a seat change that helped several people. Morning meal could have been better.

No food at all so it was a bit of a culture shock for international travellers with connecting domestic flights.

The foods were lacking in both quality and quantity. I was starving.
