Gimpo International Airport (GMP)

Gimpo International Airport operates a modern three-story terminal serving both domestic and limited international routes, primarily to East Asia. The terminal handles approximately 28 million passengers annually with efficient layout facilitating quick connections. Domestic operations dominate the southern wing while international flights use the northern section with clear separation. Walking distances are manageable: check-in to gates typically 8-15 minutes, maximum gate-to-gate transfers 20 minutes including security re-screening when required. Security processing is generally efficient taking 10-20 minutes for domestic flights and 15-25 minutes for international departures. Immigration for international passengers adds 10-25 minutes depending on time of day. The terminal features modern amenities including duty-free shopping, Korean restaurants, cafes, and airline lounges. Gimpo's proximity to Seoul city center makes it highly convenient with subway Line 5 and Line 9 providing direct connections in 20-30 minutes. Airport Railroad Express also connects to Hongik University and other key Seoul stations. The airport serves as a major domestic hub complementing Seoul's main international gateway at Incheon.
