Flights from Washington to Taiwan: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Washington to Taiwan 
Verified travelerFlew with EVA AirSEA-TPEMar 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 AirlinesSEA-TPEFeb 2025
It is a big terminal, so make sure to have enough time between flights if you are transiting here.

I didn't like the 5 hour plane change/layover in Taipei.
Verified travelerFlew with EVA AirSEA-TPEFeb 2024
Wait at gate 15 or 16. EVA Airways is pretty big in the South Asian area, but in SeaTac they have to share a gate with a bunch of other airlines.
