Busan is served primarily by Gimhae International Airport (PUS), a mid-sized gateway handling both domestic flights and a growing number of international routes to nearby Asian cities. Low-cost carriers and full-service Korean airlines commonly operate here, so fares can be competitive compared with Seoul gateways. The airport sits about 20–25 km west of Busan’s city centre; the Busan–Gimhae Light Rail and multiple bus lines connect the airport to downtown in roughly 30–50 minutes, with fares typically modest for public transit and higher for taxis. Pros: compact layout and frequent low-cost options. Cons: fewer long-haul connections and occasional congestion during peak holiday periods.

Seoul is served by two main airports with distinct roles. Incheon International (ICN) functions as the primary international hub for long-haul and full-service carriers, often seen as more premium and well-equipped; it lies about 48 km west of downtown and usually takes 50–70 minutes by airport express train (approx. 8,000–10,000 KRW) or 60–90 minutes by airport limousine bus (10,000–15,000 KRW), while taxis can take around 60–90 minutes depending on traffic at a higher fare. Gimpo (GMP) operates more as a domestic and regional gateway, commonly used by low-cost and domestic airlines for short-haul flights; it’s much closer at roughly 15 km from the city center, typically 20–30 minutes by subway or 30–50 minutes by bus (fares generally lower than ICN). Pros: Incheon offers extensive international connections and amenities; Gimpo is quicker for central transfers and cheaper on ground transport. Cons: Incheon’s distance can add travel time and cost, while Gimpo has fewer long-haul options and can be busier during peak domestic travel periods.

In different months, ticket prices from Busan to Seoul vary: minimum — $24 (October 2026), maximum — $86 (May 2027). Typically, the flight costs $58–$74.
