Nepal Airlines (formerly known as Royal Nepal Airlines) is the flag carrier airline of Nepal. Its head office is in the NAC Building (formerly RNAC Building) in Kathmandu, and its main base is Tribhuvan International Airport, Kathmandu. The airline was established in July 1958 as Royal Nepal Airlines Corporation (RNAC). The airline's first aircraft was a single Douglas DC-3, used to serve domestic routes and a handful of destinations in India. The airline acquired its first jet aircraft, Boeing 727s, in 1972. In 2004 the government of Nepal decided to sell off 49% of its stake in Nepal Airlines to the private sector. As of 2012, the airline operates a fleet of seven aircraft and flies to 39 destinations—seven of which are international. - Source: Wikipedia
