Tribhuvan International Airport (KTM) in Kathmandu is Nepal’s main international gateway and functions as the country’s primary hub for both international and domestic flights, with carriers ranging from full-service international airlines to local and regional operators. Prices can feel premium compared with intra-regional services, especially during peak trekking seasons. The airport sits a short drive from central Kathmandu—roughly 6–10 km depending on traffic—reachable by taxi (about 20–45 minutes, fares typically modest) or local buses and shared jeeps that take longer but cost less. Pros: convenient for onward domestic connections and quick access to the city; cons: limited terminal capacity, crowds, and occasional delays due to weather and terrain.
Indira Gandhi International Airport (DEL) serves as Delhi’s primary international hub and the country’s busiest gateway, handling a mix of full-service carriers, premium international airlines and numerous low-cost domestic operators. Located about 16–18 km southwest of New Delhi’s central Connaught Place, travel to the city center typically takes 30–60 minutes by taxi or app-based car depending on traffic, or roughly 20–35 minutes on the Airport Express train; fares can range from inexpensive metro fares to moderate taxi or train ticket prices. The airport is well equipped with lounges, extensive retail and transit facilities, and multiple terminals—making it convenient for international connections. Downsides can include variable security and immigration wait times during peak hours and longer transfers between terminals for some flights.
