Seoul is served primarily by two airports with distinct roles. Incheon International Airport (ICN) functions as the city’s main international hub and typically handles long-haul and premium carriers; it’s about 48 km west of downtown Seoul and can take 45–70 minutes by AREX express or 60–90 minutes by highway bus/taxi depending on traffic, with fares ranging from moderate to higher for premium rail and variable for buses/taxis. Gimpo Airport (GMP) is closer—around 15 km west—and usually serves domestic flights and short-haul international routes, often preferred by budget and full-service Korean carriers for quick transfers. Travelers can reach Gimpo by metro in roughly 20–30 minutes for low cost, or by taxi in 30–50 minutes. Pros: Incheon offers extensive international connections and full passenger services; Gimpo provides convenience and shorter city access. Cons: Incheon’s distance can mean longer transfer times, while Gimpo has fewer long-haul options.
Sofia Airport (SOF) functions as Bulgaria’s main international gateway and typically handles a mix of full-service carriers, regional European airlines and low-cost operators, making it a common choice for both business and budget travellers. It lies about 10–12 km east of the city centre; transfer options include Metro Line M4 (roughly 20–30 minutes), taxis (20–40 minutes depending on traffic) and airport shuttle buses with fares varying from modest flat bus rates to taxi metered fees. The airport usually offers a compact layout with straightforward connections and basic shopping/food options, though peak times can bring queues; its convenience for central Sofia is a clear advantage, while its relatively small size can limit late-night service variety.
