Lukla is a village in Khumbu and home to the regions sole airport. Most travelers visiting the region will enter and exit from here.
Lukla is basically just an airport and a strip of hotels. There are two expensive, up-scale places which offer such luxuries as hot tubs, while the other hotels are pretty much a sameness.
There are numerous flights plying the busy Kathmandu - Lukla route, though with a much reduced service during the off-season months. Sita is considered to be one of the more reliable airlines flying this route and operates two flights every morning from Kathmandu Domestic Airport at 7AM and 8:20AM, with return flights at 7:40AM and 9AM. Flights from Kathmandu take around 25 minutes. Be aware that during the summer rainy season there may be substantial delays, and even a wait of one week is not uncommon.
