Kathmandu to Biratnagar Flight

The Kathmandu to Biratnagar flight is the fastest and most convenient way to travel from Nepal's capital to eastern Nepal. Biratnagar is Nepal's second-largest city and an important gateway to the eastern region. The flight from Tribhuvan International Airport lands at Biratnagar Airport in the Terai plains, approximately 72 meters above sea level.

The flight takes around 45–50 minutes and saves travelers from a 12–14 hour road journey. Biratnagar is a convenient starting point for trips toward Ilam's famous tea gardens, Dharan, Koshi Tappu Wildlife Reserve, and the road toward Taplejung and the Kanchenjunga region. On a clear morning, travelers may also enjoy views of the eastern Himalayan range from the aircraft.
