Frequently asked questions
Are Lukla flights often delayed?
Delays are common enough that Everest itineraries should include buffer time. Weather and visibility can change quickly in the mountains.
Can I take a helicopter instead of a Lukla flight?
Often yes, depending on weather, aircraft availability, group size, and route. Helicopters are useful as transfers or backup options but are not immune to weather.
