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

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!

Crew was good. Sometimes food was eh. The spaghetti is gross for me. First time i got food, they didn’t provide utensils so i ate with my hands. I was hungry. They gave it to me 20 mins later when a crew member came by. I would fly with them again. Nobody is perfect

Eva air was fine - Trip.com via KAYAK sold my family access to a “VIP” lounge fo a layover in Taipei… i’m please look at my pictures. It was a scam, Trip.com knows it and they are perpetrating a fraud through your web site.

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.
