Lukla flight from Manthli Airport, Ramechhap
Due to the air traffic in Kathmandu during the peak months (March, April, May, September, October, and November), CAAN has promulgated the notice that the flight has been shifted to Manthali from Kathmandu to Lukla. If there are changes will update you ASAP.
All we know is that the Lukla flight is sensitive in the case of weather. Instantly it may be delayed and canceled as well. A tiny Himalayan airport has difficulty facing heavy traffic which is why sometimes the flight may be delayed. So, we suggest, if you are trekking in Everest, please make sure at least you have two days additional in the program.
In the case of a weather cancellation, the best alternative to get Lukla is to charter a helicopter because the copter can fly in lower visibility of 1,500 meters. However, Twin Otter and Dornier aircraft need minimum visibility of 5,000 meters.
