Currently the flight to Lukla and back takes place from Manthali which is 140km away from Kathmandu. it takes 4 hours to get there on the winding roads. For the first day of joining the tour, you need to arrive in Kathmandu by midday as you will be received at the airport, driven to Mulkot to stay overnight. The drive from Mulkot to the airport is one hour. This saves having to leave Kathmandu at around 2 am to catch the early morning flight. This has been done to avoid the delays caused by foggy weather at Kathmandu airport.
