Yeti Airlines started its first commercial flight in September 1998 with a single Canadian built DHC6-300 Twin Otter aircraft. Within a decade it became the largest domestic airline operator with a fleet of BAE Systems Jetstream-41, DHC6-300 Twin Otter and the German built Dornier Do 228 aircraft.In 2009, its sister airline Tara Air was established to take over the Short Take Off and Landing
(STOL) operations with the DHC6-300 and Dornier DO228 aircraft fleet. Yeti Airlines has retained its modern fleet of seven Jetstream 41 twin turbo prop aircraft that operate on non-STOL domestic sectors of Nepal. The two airlines together continue to provide the largest network of flight routes throughout Nepal.
