Tribhuvan International Airport has issued a NOTAM (notice to airmen) and warned of flight disruptions on Saturday and Sunday in view of VVIP movements.

The notice has been issued for the arrival of Chinese President Xi Jinping, who is scheduled to land at TIA from Chennai on Saturday evening.

"A NOTAM has been issued for Saturday, October 12 from 14:55 to 15:25," said the notice issued by TIA. "For Sunday, October 13, a NOTAM has been issued from 11:20 to 13:50."

TIA management has said the airport will be in operations all night on Saturday to manage rescheduled arrivals and departures.

Xi and the Chinese delegation will be landing at TIA on Saturday evening, scheduled between 16:30 and 17:30, on two Boeing 747s.

During his 2o-hour stay in Kathmandu, the Chinese president will hold meetings with President Bidya Devi Bhandari, Prime Minister KP Sharma Oli and former prime ministers Pushpa Kamal Dahal and Sher Bahadur Deuba.

Xi and the Chinese delegation will depart for Beijing from TIA on Sunday afternoon at around 12:30.

Flights are expected to operate on time by Monday morning. For the already congested Kathmandu airport, the only international airport in the country, which usually struggles to ensure timely arrivals and departures, VVIP movements make the situation worse.

TIA has revised the schedule of 33 and 54 international flights for Saturday and Sunday, respectively.
