Netaji Subhas Chandra Bose International Airport (CCU) serves Kolkata as the city’s main international and domestic gateway, typically handling full-service carriers alongside low-cost airlines. Located about 15–18 km northeast of the city center, travel times to central Kolkata are usually 30–60 minutes by taxi depending on traffic; app taxis and prepaid airport counters are common, and the metro extension to the airport can cut journey times when operational, often offering lower fares than road options. The airport tends to offer a broad choice of flights but can be busy at peak hours; it’s generally convenient for international connections yet can involve longer commute times in heavy traffic compared with more compact city airports.
Bangkok is served by two main airports with distinct roles. Suvarnabhumi (BKK) is the international hub handling most long-haul and full-service carriers; it sits about 25–30 km east of central Bangkok and usually takes 30–60 minutes to reach by car depending on traffic. Options include the Airport Rail Link (25–40 minutes to Phaya Thai), taxis (variable by congestion), and app-based rides; fares commonly range from a few dollars for rail to higher taxi costs plus tolls. Don Mueang (DMK) is the older, budget-leaning airport to the north, typically used by low-cost and regional airlines and around 20–25 km from the city center; travel times are often 30–60 minutes by road, and shuttle buses and cheap taxis are common. Suvarnabhumi tends to be more comfortable and better connected for international transfers, while Don Mueang can be more economical for short-haul or budget travelers; the trade-offs involve convenience versus lower fares and sometimes longer surface transfer times.
