KATHMANDU, Feb. 27 -- Trekking entrepreneurs have said that the decision to close runway of Tribhuvan International Airport (TIA) from 10 pm to 8 am from April 1 will affect Nepal's adventure tourism business.

In a NOTAM issued to airline companies, Tribhuvan International Airport Civil Aviation Office (TIA CAO) said that the TIA runway will remain closed for 10 hours daily till June 30 for rehabilitation and expansion works. Airline operators have changed their flight schedule accordingly. As per the new schedule, flights to Lukla will take off from Ramechhap Airport.

The decision is certain to increase cost of operation of trekking entrepreneurs, who generally accept bookings months ago, as it will incur extra costs.
