Every year, Lukla Airport is flooded with tens of thousands of trekkers and climbers. During the busiest hiking and climbing seasons, people set off on their daring adventures in the Everest region. The two main seasons are autumn (September, October, and November) and spring (March, April, May). In addition, there are also a good number of tourists in May, September, and December. The airport receives a number of aircraft each day due to the consistent weather, which includes clear skies and sunny days. The airport occasionally becomes busy and jammed.
