Seoul is served mainly by Incheon International (ICN) and Gimpo (GMP), each with a distinct role. Incheon is the country’s principal international gateway and a full-service hub for long-haul carriers; it typically hosts flag and major international airlines and can be seen as a mid-to-premium option in terms of facilities and connectivity. Located about 48–60 km west of downtown Seoul, transfer options include the AREX express (35–55 minutes), regular AREX and airport buses (60–90 minutes) or taxis (around 60–90 minutes, depending on traffic). Fares vary by mode—AREX express is generally pricier than buses but faster. Pros: extensive amenities, smooth international transfers; cons: longer transfer time to central Seoul and larger terminal walks. Gimpo operates more as a domestic and regional airport, often serving low-cost carriers and short-haul international routes to nearby Asian destinations. It sits much closer to the city — roughly 15–20 km west of central Seoul — and can be reached quickly by subway (Line 5/9/AREX, typically 20–30 minutes), airport buses (30–50 minutes) or short taxi rides (20–40 minutes). Tickets and fares tend to be lower for domestic connections, and the airport can be more convenient for quick hops or budget-conscious travelers. Pros: proximity and faster city access; cons: fewer long-haul amenities and more limited international route options.

San Francisco International (SFO) is the region’s primary international hub, handling most long-haul and premium carrier flights alongside many domestic services; United and major global airlines are typically prominent, while some low-cost carriers also operate. It sits about 13 miles south of downtown San Francisco, with BART taking roughly 30–35 minutes to reach the city center and fares generally in the low-to-mid single digits; airport shuttles, taxis and app-based rideshares are common and can take 20–45 minutes depending on traffic. Pros: extensive international connections, plentiful lounges and car-rental options. Cons: can be busy at peak times and security lines may be lengthy.
