The plane was half empty and I lucky to get three seats to myself allowing me to stretch my legs. Even without that the regular leg space in economy was quite comfortable compared to some other planes in recent memory. Food was fine I’m not vegetarian, but neither of the options offered was. So order vegetarian ahead when checkin in.

The plane was half empty and I lucky to get three seats to myself allowing me to stretch my legs. Even without that the regular leg space in economy was quite comfortable compared to some other planes in recent memory. Food was fine I’m not vegetarian, but neither of the options offered was. So order vegetarian ahead when checkin in.

Picked our seats when we purchased this flight (2 seats alone on the right) but were assigned two middle seats in the middle row at the gate. Very disappointing for a 10 hour+ flight, and what is the point of picking and paying for seats ahead of time when they just reassign us?

First international flight where the meals were not to my taste.

Overall, my experience with EVA Air was mixed. The highlight was that the airline clearly tried to provide a premium dining experience by offering the Michelin-starred Kanpai Classic beef yakiniku rice. However, in the limited space of an economy-class cabin, this meal felt overly oily and not very practical to eat. The sauce and grease made it easy to get one’s hands or tray table dirty, and after the meal many passengers may need to go to the lavatory simply to wash their hands. While the food itself may be high quality, the presentation and practicality did not seem well suited to an in-flight environment. Another disappointing part was the paid Wi-Fi service. I paid for the internet package, but the service did not work properly. What made the experience more frustrating was that passengers then had to spend additional time requesting a refund, and the refund process itself was slow and inconvenient. For an international airline, I think a malfunctioning paid service should be handled more efficiently. As for the seat, I feel EVA Air’s economy-class seats may be more comfortable for Asian passengers or people with smaller body frames, but they may not be as comfortable for taller or larger Western passengers on long-haul flights. The overall cabin environment also varied during the flight. Some passengers were not very mindful of noise, cleanliness, or shared cabin etiquette, which affected the comfort of the journey. I believe clearer reminders from the airline regarding cabin manners and hygiene could help improve the overall passenger experience. In short, EVA Air has some strong points, especially in trying to offer a premium Taiwanese-style service, but there are also areas that need improvement: more practical in-flight meals, a more reliable paid Wi-Fi system, faster refund handling, and better cabin management during long-haul flights.

Other than spotty internet, great servic, comfortable and smooth flight!

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

Pleasant crew. Very long flight, a bit uncomfortable at times being seated, but not too bad.

No ice for the drinks. Only gave a half a cup of your beverage. Not enough water. I got very dehydrated.

Polite hard working crew. No complaints really. Meals were not to my liking.

Everything was fantastic! The crew really went above and beyond to make it a great flight. I felt cared for with EVA.

I had bad experience with United airline. No live rep, they only have AI that respond to customers concern

Flight and crew were great. Need more legroom and do not allow seats to recline.

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

The Code Share with Air Canada was not very streamlined. I had to check in at airport (not online) on the outbound and return flights

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

Was on the plane sitting longer than the actual flight in air was, boarded at 5:45p and didn't take off until 6:50p flight was only about 30 minutes long. Just was poor experience will booking more with American Airlines.

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.
