The thick smog that engulfed the valley affected flights to two domestic destinations today.

According to the Tribhuvan International Airport, flights to Pokhara, Bharatpur and other destinations were affected due to poor visibility that was created by air pollution since today morning.

According to the domestic airport office, the airlines including Buddha Air and Shree Airlines, which have been operating regular flights to Pokhara, cancelled their flights today.

Similarly, the flights in the Kathmandu-Bharatpur route were also halted due to the hazy conditions.

"Regular domestic flights have been affected due to the pollution. While the flights to Pokhara and Bharatpur were delayed on Tuesday, the flights on the routes had to be cancelled today," said an employee of the airport office.

Even 12 days ago, both domestic and international flights from the capital were affected due to the thick smog.

While flights were earlier affected only during winter season due to foggy weather, mostly domestic flights have been affected in the recent days due to heavy air pollution.

Meanwhile, the international flights were unaffected today.

Chopper operations, however, were also affected.

With onset of spring season, expedition season has also started. However, due to pollution, many flights have been cancelled. Just last week, chopper operations had been halted for four days.
