Bangkok is served primarily by two airports with distinct roles. Suvarnabhumi (BKK) is the international gateway and regional hub for full-service carriers like Thai Airways and many global airlines; it can be pricier to fly into but offers more long-haul connections. The airport sits about 30–40 km east of central Bangkok; the Airport Rail Link takes roughly 30–45 minutes to Phaya Thai with fares typically in the budget range, while taxis usually need 30–60 minutes depending on traffic and can add a motorway toll. Pros: extensive facilities, frequent international services and better lounge/transfer options. Cons: busy terminals and occasional congestion on roads.
Don Mueang (DMK) functions largely as a budget and domestic-focused airport, popular with low-cost carriers such as Thai Lion Air and Nok Air. It lies roughly 20–25 km north of downtown; buses and airport shuttles take about 30–60 minutes, and taxis are a common choice with similar journey times depending on traffic. Fares for public buses are typically very low, while taxi metered trips are moderate but can be slower in peak hours. Pros: often cheaper fares and quicker processing for budget flights. Cons: fewer long-haul options and more limited transfer amenities compared with the main international airport.
Busan is served by two main airports with distinct roles. Gimhae International Airport (PUS) is the primary gateway for both domestic and short-haul international flights, handling carriers from full-service Korean airlines to low-cost carriers; fares here can be midrange to budget-friendly depending on the carrier. It sits about 20–25 km from downtown Busan; airport buses and the metro Green Line typically take 30–50 minutes (fares usually range from modest city-bus prices to slightly higher airport express rates). Pros: convenient public-transit links and many budget options; cons: can be busy at peak times and limited long-haul connectivity. For sea- and luxury-focused travelers, occasional ferry terminals nearby provide alternative links to regional ports.
