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.

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.
