Facts About Flights from Hong Kong International to Seoul
To help you plan your journey, here are some quick Seoul flight facts and tips.
Seoul airports
Incheon International Airport (ICN) and Gimpo International Airport (GMP) both serve the Seoul Metropolitan Area, offering distinct roles in South Korea's air travel landscape. ICN is the primary international gateway, handling the vast majority of international flights to and from South Korea. It's known for its modern facilities, numerous amenities, and connections to destinations worldwide. Gimpo, while formerly the main international airport, now primarily handles domestic flights and a limited number of international routes, mainly to destinations in Asia. It offers a more convenient option for travelers focusing on regional travel within Asia or domestic travel within South Korea, due to its closer proximity to Seoul compared to Incheon. Choosing between the two depends on your destination: international travelers will likely arrive/depart from ICN, while those flying within Korea or to select Asian cities may find GMP more suitable.
Pro tip: search “Seoul (Any)” to see fares to all Seoul airports – sometimes one is cheaper than the others on your dates.
