Bangkok is served primarily by two airports with distinct roles. Suvarnabhumi (BKK) is the international hub for full-service carriers and long-haul flights, typically handling most premium and transfer traffic; it lies about 30–35 km east of central Bangkok and can take 30–60+ minutes by taxi depending on traffic, with fares generally in the mid-range for the city. Public options include the Airport Rail Link (25–35 minutes to central stations) and airport buses. Don Mueang (DMK) is an older, budget-leaning airport north of the city, commonly used by low-cost carriers and regional services; it’s roughly 20–25 km from downtown, often 30–50 minutes by car, with lower taxi fares on average. Bus and shuttle services connect it to Mo Chit BTS/MRT in about 20–40 minutes. Pros: Suvarnabhumi offers more international connections, extensive facilities and comfortable transfer options; Don Mueang can be quicker and cheaper for budget travelers but may feel more basic and crowded at peak times. Both airports can require extra time for traffic and transfers, so allow a healthy buffer for connections.
Netaji Subhas Chandra Bose International Airport (CCU) serves Kolkata as the city’s main international and domestic gateway, handling full-service carriers and many low-cost airlines alike. The airport is typically positioned as a major regional hub for eastern India, with international flights to Southeast Asia, the Middle East and Europe alongside frequent domestic connections. It sits about 16–20 km from the city centre; road transfer times are commonly 30–60 minutes depending on traffic, with taxi and app-based rides the fastest options and municipal buses or prepaid airport taxis usually costing modest fares. Pros: fairly extensive facilities and multiple carrier choices; cons: can be busy and affected by peak-hour congestion, so allow extra time for transfers.
