During peak travel seasons such as spring and pre-winter, Lukla flights may take off from Manthali Airport in Ramechap. This is done to avoid congestion at Kathmandu Airport. The Lukla airport is the busiest among the STOL runways operated from Kathmandu, and to avoid congestion at the airport and limit the load, all flights to Lukla may be redirected to Ramechap for smooth operation.
