Flight from Seattle to Taipei City

ChristineFlew with EVA Air-Apr 2026

Look up the actual seating room on the plane you fly, especially if you're over 5'3" and flying economy. EVA Air does provide vegetarian meals by early order and they seem to be vegan.

RogerFlew with STARLUX Airlines-Feb 2026

Check out the menu before you board, and if you have time utilize the Galactic Lounge at T2

Verified travelerFlew with EVA Air-Mar 2025

Arrive early at the airport. Bring personal items like toothbrush and toothpaste if needed because it’s a long flight. If you’re flying with Eva, I don’t think you’ll need more than that.

Verified travelerFlew with China Airlines-Feb 2025

It is a big terminal, so make sure to have enough time between flights if you are transiting here.
