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.

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

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

I like Eva Air. I’ve been flying it for several years.. I did notice small changes for the worse by the staff. They’re still way above major carriers based in the USA.

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.
