Frequently asked questions

Is it cheaper to buy a plane ticket from IST to ICN last minute?
Booking your trip from IST to Incheon Intl. Airport (ICN) at the last minute could help you save if you’re lucky to find a bargain. However, airfares generally don’t get cheaper as the date of departure nears. If you hold off, flights could also be sold out or the best seats gone (hello, middle seat!). If you’d rather not hedge your bets, book well in advance of your departure date. It’s worth noting that some of the best deals can be found up to a year in advance. If your preferred carrier hasn’t released tickets yet, check back regularly as offers are updated on Expedia all the time.
What airports do you fly into for Seoul from Istanbul?
From Istanbul, you can connect to Seoul through Incheon Intl. Airport (ICN), Gimpo Intl. Airport (GMP) and Suwon (SWU-Suwon Airbase). Determine which terminal is the right option for you before making your decision. If you decide to land at Incheon Intl. Airport (ICN), it’s around 30 mi west of downtown. Use the dollars you save when booking your trip with Expedia to check out the city’s popular sights, such as Starfield COEX Mall and Lotte Outlets Seoul Station.
