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

Insights shared by verified travelers who flew the route from Washington to Asia 
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.
RenaFlew with Japan AirlinesSEA-NRTMar 2025
Good choice for non-stop Seattle to Tokyo.
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.
Verified travelerFlew with Asiana AirlinesSEA-ICNDec 2024
Asiana is a good airline to fly on.
larryFlew with STARLUX AirlinesSEA-TPENov 2024
I didn't like the 5 hour plane change/layover in Taipei.
Verified travelerFlew with Singapore AirlinesSEA-SINAug 2024
If you need special meals book them early
J&SFlew with Japan AirlinesSEA-NRTMay 2024
JAL's service and food was more superior compared to the two airlines I had flown previously, i.e.UA and Delta.
lizFlew with Asiana AirlinesSEA-ICNMay 2024
Do try to snooze on long haul flights, bring a good book to read, choose an aisle seat.
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.
JeffFlew with Singapore AirlinesSEA-SINJan 2024
Delta & Alaska have best boarding process! Singapore airlines was ok!
