Indira Gandhi International Airport (DEL) is Delhi’s main international gateway and a major South Asian hub, handling full-service carriers and many international low-cost airlines alike. It typically serves most long-haul and regional connections while the newer Terminal 1 can be used for some domestic budget services during peak changes. DEL sits roughly 16–20 km southwest of central New Delhi; road transfers usually take 30–60 minutes depending on traffic, while the Airport Express metro line links the city center in about 20–25 minutes with fares generally low-to-moderate. Pros include wide service options, modern facilities and frequent connections; cons can be longer queues and variable transfer times in rush hours.
Tribhuvan International Airport (KTM) in Kathmandu is Nepal’s principal international gateway and typically functions as the country’s main hub for both foreign carriers and domestic airlines. You’ll commonly find full-service international operators alongside numerous domestic and regional carriers serving hill destinations. Flights to KTM can be pricier than to secondary airports in the region, especially during peak trekking seasons. The airport sits about 6–8 km east of central Thamel; taxi rides usually take 20–40 minutes depending on traffic and cost roughly NPR 300–1,000, while ride-hailing and airport shuttles are also available. Pros: convenient access to the city and a range of onward domestic connections. Cons: limited terminal capacity, occasional congestion, and basic facilities compared with larger international hubs.
