Bangkok is served primarily by two airports with distinct roles. Suvarnabhumi (BKK) is the international hub and main long-haul gateway, typically handling premium carriers and full-service airlines; it sits about 30–40 km east of downtown and is usually reached by the Airport Rail Link (25–35 minutes), taxis (30–60 minutes depending on traffic) or shuttle buses. Don Mueang (DMK) is nearer the city (about 20–25 km north) and often functions as the low-cost and regional airport for budget airlines; travel times by taxi are commonly 25–50 minutes and shuttle buses or rideshares provide alternatives. Fares can vary widely with taxis or rideshares often costing a moderate amount and the rail link offering the lowest predictable cost. Pros: Suvarnabhumi tends to be more modern and comfortable for long-haul connections, while Don Mueang can be quicker for budget travelers. Cons: Both can be affected by Bangkok traffic, and transfers between airports typically take an hour or more, so allow extra time for connections.
