Netaji Subhas Chandra Bose International (CCU) serves Kolkata as the city’s main international and domestic gateway, typically handling full-service carriers alongside growing low-cost airline operations. Located about 17–20 km from the city center, travel times can be roughly 40–70 minutes by road depending on traffic; app taxis and prepaid airport cabs are common (fares often fall into a modest range), while the recently expanded metro link can cut commute time and cost further. The airport usually offers standard amenities and multiple airline lounges, making it convenient for international and connecting travelers, though peak-hour road congestion can make ground transfers less predictable for time-sensitive itineraries.

Tribhuvan International Airport (KTM) is Nepal’s main international gateway and the country’s busiest airport, handling most long-haul and regional flights alongside a mix of full-service and low-cost carriers. Located about 6–8 km east of central Kathmandu, travel time to Thamel or the Ring Road is typically 20–40 minutes depending on traffic. Ground transport options include taxis (metered or fixed fares), ride-hailing services, and occasional airport shuttles; fares can vary widely but are generally modest by international standards. The airport is convenient for onward connections and central hotels, though it can be crowded and facilities are more basic compared with larger global hubs. Security procedures and peak-hour congestion can slow transfers, but KTM remains the most practical arrival point for most visitors to Kathmandu.
