Vayudoot was a regional airline in India established on 20 January 1981 as a joint venture between the two state-owned carriers, Indian Airlines and Air India. The airline was headquartered at New Delhi's Safdarjung Airport and was originally conceived to serve Northeast India. The regional hub for the region was Calcutta and the airline flew to close to 30 destinations in this challenging area. Many of the airfields saw the resumption of commercial flights and fixed-wing aircraft after many decades of their absence.
