Frequently asked questions

Is it cheaper to buy a plane ticket from San Antonio Airport to ICN last minute?
Being a spontaneous soul is a terrific way to travel, but it isn’t always the best way to get your hands on a cheap plane ticket. Consider booking your San Antonio Airport to Seoul–Incheon Intl. Airport trip well in advance rather than leaving it to the last minute. Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. We recommend saving that spontaneity for when you reach Seoul–Incheon Intl. Airport!
What airports do you fly into for Seoul from San Antonio?
Incheon Intl. Airport (ICN), Gimpo Intl. Airport (GMP) and Suwon (SWU-Suwon Airbase) are your options when taking off from San Antonio to Seoul. Roughly 30 mi west of the heart of Seoul, Incheon Intl. Airport (ICN) is the city’s principal hub. Take into account things like flight departure and arrival times and the distance to your hotel before deciding where you fly into.

Can I change the date of my flight from San Antonio Intl. Airport (SAT) to Incheon Airport?
You can make changes to your SAT to Seoul–Incheon Intl. Airport flight via the Expedia Trips portal.
