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

Organized boarding process, superb food, lovely crew, even arrived early!

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.

Gluten free snack options and meals that offer both gluten free and dairy free.

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

The Wi-Fi did not work, so you weren't able to watch entertainment on your own device. They did not have wired headphones so you couldn't watch it on the in-seat entertainment screen either. There was plenty of time to do a drink and snag service but the flight attendants chose not to.

Great experience, boarding was fast and efficient, so much so that we arrived to Chicago very early

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

Food was not great. Small seating area for business class
