Known by its IATA code KTM, Tribhuvan International Airport connects Nepal with major cities across Asia, the Middle East, and beyond. It also serves as the central domestic aviation hub, linking Kathmandu with remote Himalayan airstrips and popular tourist destinations throughout Nepal.

History of Tribhuvan International Airport
The history of Kathmandu’s airport dates back to 1949 when the first aircraft landed on a grassy field known as Gauchaur. Initially built for basic aviation operations, the airport gradually developed into Nepal’s international aviation center.
In 1955, the airport was renamed Tribhuvan International Airport in honor of King Tribhuvan, who played an important role in modern Nepalese history. Over the decades, the airport expanded significantly with improvements in terminals, runways, air traffic systems, and passenger facilities.
Today, KTM remains Nepal’s most important airport for international and domestic connectivity.
