Tribhuvan International Airport (TIA) handled a record 5.04 million international passengers in 2025, marking a 1.64 percent increase from the previous year, according to aviation data. Growth was largely driven by outbound migrant workers and students, while tourist arrivals rose modestly to 1.15 million. The airport managed 34,600 international flights, averaging 95 per day, despite operational challenges caused by ongoing taxiway construction. Nepal Airlines carried the highest number of passengers at 606,333, followed by Air India, Himalaya Airlines and Qatar Airways. Indian carriers increased their market share due to more frequent flights and competitive fares. Capacity is expected to expand after the parallel taxiway project is completed by the end of 2026.
