Ulsan Airport (USN) serves as a regional gateway for the industrial southeast of South Korea, functioning mainly as a domestic hub with occasional international charters. It typically handles short-haul flights operated by local carriers and low-cost airlines, so fares can be relatively affordable compared with major international hubs. The airport sits about 16–20 km from Ulsan city center; taxis usually take 20–35 minutes, while local buses may take 30–50 minutes depending on route and traffic, with fares generally low. Pros include quick check-ins and short transfer times; cons can be limited dining and shopping choices and fewer direct international connections than larger airports in Busan or Seoul.

Incheon International Airport (ICN) serves as Seoul’s primary international gateway and a major regional hub, handling most long-haul and many transit flights for full-service carriers and global alliances. Located about 48 km west of downtown Seoul, travel to the city center typically takes 45–70 minutes by AREX express/train, 60–90 minutes by airport limousine bus, or around an hour by taxi depending on traffic; fares for rail and bus options can be expected to be moderate for international standards. The airport is known for modern facilities, duty-free shopping and extensive transfer services, making it comfortable for connections, while the longer distance to central Seoul can be a downside for tight schedules. Gimpo International Airport (GMP) functions as Seoul’s more domestic- and short-haul-focused airport, often serving low-cost carriers, regional flights to Japan/China and frequent domestic services. It sits roughly 15 km west of downtown, so ground transfer options are quick — AREX commuter trains and subway lines typically take 20–30 minutes to central Seoul, airport buses run similar times, and taxis are relatively affordable for short trips. Gimpo can be a convenient, budget-friendly choice for point-to-point travel within Korea or nearby countries, though it offers fewer long-haul amenities and limited international connectivity compared with Incheon.

In different months, ticket prices from Ulsan to Seoul vary: minimum — $51 (June 2026), maximum — $67 (August 2026). Typically, the flight costs $59–$126.
