Frequently asked questions

Is it cheaper to buy a plane ticket from Seattle - Tacoma Intl. Airport (SEA) to GMP last minute?
Booking your journey from Sea-Tac Airport to Gimpo Airport at the last minute could save you money if you luck out and find a real bargain. However, airfares don't usually get cheaper as the date of departure nears. If you hold off, flights could also be sold out or the best seats gone (because no one wants the middle seat). If you want to be on the safe side, book well ahead of the date you want to leave. In fact, you can find some of the biggest deals up to a year in advance. If your preferred airline hasn't released its fares yet, check back regularly as deals are constantly updated on Expedia.
What airports do you fly into for Seoul from Seattle?
From Seattle, you can travel to Seoul through Gimpo Intl. Airport (GMP), Incheon Intl. Airport (ICN) and Suwon (SWU-Suwon Airbase). It's wise to check which terminal is more convenient for you before making your decision. If you choose Gimpo Intl. Airport (GMP), it's about 16 kilometers west of downtown. Use the money you save when booking your journey with Expedia to uncover the city's popular attractions, such as Starfield COEX Mall and Lotte Outlets Seoul Station.
Can I change the date of my flight from SEA to Gimpo Intl. Airport (GMP)?
You can make changes to your Seattle - Tacoma Intl. Airport (SEA) to GMP ticket by logging in to the Expedia Trips portal. But before you make any adjustments, check out the conditions and rules in your itinerary to see what you're allowed to do and if change fees apply.
