Kathmandu Tribhuvan International Airport (VNKT / KTM)

Kathmandu Tribhuvan International Airport is in Kathmandu, Nepal, at 27.6966° north and 85.3591° east. Its ICAO code is VNKT and its IATA code is KTM.

Kathmandu Tribhuvan International Airport stands at 4,390 ft, which is 1,338 m above sea level. That is the surveyed elevation of the landing surface itself rather than of the surrounding terrain, which is why it can differ from the height quoted for the town or the ridge above it.

6 published routes on this platform run through Kathmandu Tribhuvan International Airport: Everest Base Camp Helicopter Tour, Langtang Valley Helicopter Tour, Gosaikunda Lake Helicopter Tour, Everest Base Camp Landing Tour, Lukla – Kathmandu Charter, Everest Region Medical Evacuation. Each is quoted across every CAAN-certified operator that flies it, so the price shown is a comparison rather than one company's number.

Kathmandu Tribhuvan International Airport is VNKT in ICAO's four-letter system, and KTM in IATA's three-letter system, which is the code that appears on an airline ticket.

Formally an airport: it holds the ICAO code VNKT, which is only issued to a registered aerodrome. "Airstrip" is the informal word for the short, often unlit mountain runways that make up most of Nepal's network, and it is used about this one as often as "airport" is. Both describe the same place. What is not an airstrip is a helipad, and ten of the eighteen sites on this platform are helipads with no runway of any kind.

Syangboche Airport is the nearest registered airport to the summit, about 29 km away in a straight line, though the airport almost everyone means is Lukla Tenzing-Hillary Airport at about 39 km: it has the scheduled service, and it is where the Everest treks and most Everest helicopter itineraries begin. Kathmandu Tribhuvan International Airport itself is about 157 km from the summit. Closer than any airport are the helicopter landing sites at Everest Base Camp and Kala Patthar, neither of which has a runway.
