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.

Eva airlines has very goin service, despite being low cost. Meals and fin, not amazing, restrooms always clean and staff polite and helpful

Its fantastic!!I like the food the serve in EVA air😊

Flight was canceled was only given only a 8 hour lead time. Had to fight to be put on another airline (United Airlines) that was leaving earlier then the one EVA and rescheduled.

Awful had to ask for a supervisor to sit with my flight companion even t booked the tickets together weeks before

EVA airlines was excellent: on time or early, safe, courteous crew. Highly recommended.

EVA! What is going on with your food!?!? Pre pandemic I used to go to Taiwan at least twice a year and always flew EVA — the food was consistently tasty for airplane food. Post pandemic, it’s not great at all. Step it up!

Vegetarian options should be included with every meal. Even just simple steamed vegetables and whole grains would capture a wide audience.

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.

Extensive delays, poor organization to board people, as it felt like chaos to get inside of the plane. No lines, everyone gathering together like a mayhem, very confusing. Passengers out of hand and rude, which is not the airlines fault. However, there should be rules, e.g., not letting one passenger take 2+ spots in the overhead bin.

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

Food , drink experience were great with Cathay. Crew service was excellent. Clean toilet and full snack bars always, pilot took of 26minutes later when boarding at Hong Kong with extra US customs check at gate 9 for US flight, but he managed to arrive only 2 minutes later from flight tracker. Smooth flight .

I wish there were more bathrooms available on these larger carriers.

Overall, not good. Super late boarding in Hong Kong because some last minute issue with a plane. The boarding process is chaotic. Kathy Pacific should seek to do better with punctual departure time. Caused a lot of trouble with missed connecting flight.

Not much of anything could have been done better unless I had a first class ticket. I was literally 15 hours with an airline in the economy class. Very professional friendly and attentive crew. Good airline food, clean cabin, seating area and bathrooms. I've been 4 times back-and-forth with Cathay Pacific, and I would not choose another airline for this trip. Five out of five stars.

Crew on this flight dedicate their business class service to their high priority members. They would get priority service even the seats are behind me, and meals priority service and orders. I get the left over choices. I refused to eat because I felt discriminated, never booking this airline.

Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?
