Every producer who has filmed in the Himalaya knows the feeling: the crew is packed, the gear is weighed, the call time is 4 a.m., and the airstrip is wrapped in cloud. In Nepal, flights are the single biggest schedule risk on a mountain shoot. A grounded crew still costs money, and a missed window can mean a missed shot you cannot easily come back for.
The good news is that this risk is predictable. You cannot control the weather, but you can plan for it. This guide explains why flights in Nepal get delayed, what a bad spell really looks like, and how to build buffer days, backup transport and budget contingency into your schedule from the start.
Why flights in Nepal behave differently
Many of the airstrips that production crews rely on sit in deep valleys, with short runways and pilots flying largely by sight. Lukla’s runway, the gateway to the Everest region, is only about 527 metres long. Flights depend on clear mornings, because wind, fog and low cloud tend to build as the day goes on.
That means a delay is not always a sign that something has gone wrong. It is simply how mountain aviation works. The same is true of other weather-sensitive airstrips such as Jomsom and Simikot. Cancellations also tend to come in clusters: when one morning is lost, the backlog of passengers makes the next flying day more crowded and more uncertain.
The Manthali factor
During the busiest trekking seasons, scheduled Lukla flights have generally operated from Manthali Airport in Ramechhap instead of Kathmandu, to ease congestion at Tribhuvan International Airport. Manthali is about 132 km from Kathmandu, roughly a four-hour drive.
For a film crew, this changes the logistics in three ways:
- Early starts. The road journey often begins in the middle of the night, so crew are tired before a long shoot day even begins.
- A longer chain of things that can go wrong. Road, airstrip and weather all have to line up.
- Basic facilities at the airport. Manthali is a small airstrip, not a terminal with hotels and rental houses.
The seasons and routing are set by the Civil Aviation Authority of Nepal (CAAN) and can change from year to year, so always confirm the current arrangement with your airline or production partner before you lock in dates.
What a bad weather spell looks like
It helps to see the scale. In October 2023, more than 200 Manthali–Lukla flights were cancelled over five days of bad weather. Hundreds of travellers were stranded at Manthali, airlines shifted some flights to Phaplu to shorten the journey, and some travellers chartered helicopters, which not everyone could afford.
Now imagine that as a production. Five days of held crew, hotels, vehicles, equipment rental and permit time, with no footage to show for it. A producer who has planned a buffer, a Plan B and the right insurance sees the same spell as an inconvenience. A producer who has not may see a blown budget.

How many buffer days do you need?
There is no single number, because the risk depends on the location and the season. These are starting points that we would adjust for your project:
| Location type | Suggested buffer |
|---|---|
| Kathmandu Valley and major cities | One flexible day across the shoot |
| Terai, Chitwan, Lumbini and Pokhara | One contingency day per week, more in winter fog season |
| Weather-sensitive airstrips (Jomsom, Simikot) | One day at each end, plus a float day |
| Everest region via Lukla | Two days at each end, plus a float day per week of mountain work |
| Multi-location series | Buffer at every flight, not just once |
The days at the end matter most. Many producers lose a schedule not on the way in, but on the way out, when a crew is stuck in the mountains and an international flight home departs without them.
Schedule around the buffer
A buffer only works if the schedule is built to use it. A few habits make a big difference:
- Front-load the hardest locations. If a weather spell is going to hit, you want it to eat into the end of the schedule, not the start.
- Keep a list of weather-flexible work. Interviews, interiors, cultural scenes and pick-ups can fill a hold day that would otherwise be lost.
- Never book an international flight the day after a mountain flight out. Leave at least one or two days of margin, and use flexible tickets where you can.
- Set a daily go or no-go time. Agree who decides, when, and what the fallback is, so that nobody is waiting on an airstrip hoping.
- Decide who flies first. On a limited flight, will you send key crew or gear ahead? Make the call before the day, not on the runway.
For the forecast, check Nepal’s Department of Hydrology and Meteorology, and ask your local production team for same-morning airstrip updates, since conditions at the strip can differ from the regional outlook.

Gear and baggage on small aircraft
Small aircraft mean tight weight limits. In peak season, passenger baggage allowances on Lukla flights are commonly in the 10 to 15 kg range, and airlines may refuse extra bags to keep the plane light. A cinema camera package will not fit inside that.
Plan cargo early, ship what you can ahead of the crew, and rent locally where it makes sense. See our guides on transporting film equipment in Nepal and on-site gear support.
Plan B transport
A good plan has at least two ways to reach every key location. Here is how the common options compare:
| Option | Best for | Trade-offs |
|---|---|---|
| Helicopter charter | Time-critical moves, getting a crew in or out after a long cancellation | Highest cost, and helicopters are weather-dependent too |
| Alternative airstrip (for example Phaplu) | Shortening the road or trek after a multi-day closure | Availability depends on airlines and current conditions |
| Road transport | Locations reachable by jeep, then trek | Slow, and not an option for every destination |
| Hold in Kathmandu or Manthali | Short delays and uncertain forecasts | Costs crew days, but the cheapest option if the weather clears |
Agree in advance who can authorise a helicopter charter and up to what cost. Making that decision in the moment, under pressure, is how budgets get broken.
Budget and insurance
Treat weather and travel delays as a separate line in your budget, not as something absorbed by general contingency. The usual costs include:
- Extra hotel nights and per diems
- Held crew and standby day rates
- Vehicle and driver holds
- Equipment rental extensions
- A helicopter charter allowance
Then check your insurance. Not every policy covers weather-related delay, and standard travel insurance may not cover production costs or helicopter evacuation. Our guide to film insurance and liaison officer requirements in Nepal explains what foreign productions need, and our crew safety guide covers medical and evacuation planning.
Quick checklist
- Buffer days built into the schedule, especially at the end
- International flights booked with margin or on flexible tickets
- A Plan B transport option for each key location
- Named decision-maker and a spending limit for charters
- Weather-flexible shots listed for hold days
- Gear weights checked against current airline limits
- Insurance confirmed for delay, charter and evacuation
- Daily weather and flight check routine agreed with your production partner
Frequently asked questions
How often are flights to Lukla cancelled?
There is no fixed rate, because cancellations depend on the weather. They tend to come in clusters, with several lost days in a row, so plan for a spell of bad weather rather than a single missed morning.
How many buffer days should I add to a Nepal film shoot?
It depends on the location. For the Everest region via Lukla, we suggest two days at each end plus a float day per week of mountain work. Kathmandu Valley and the Terai need far less. See the buffer table above.
Why do Lukla flights leave from Manthali instead of Kathmandu?
In peak trekking seasons, flights have generally been moved to Manthali Airport in Ramechhap to ease congestion at Tribhuvan International Airport. It is about 132 km from Kathmandu, a drive of roughly four hours. The Civil Aviation Authority of Nepal sets the dates, so confirm them before you book.
Can we use a helicopter if flights are cancelled?
Often, yes, but helicopters are also affected by weather and cost far more than a scheduled seat. Agree in advance who can authorise a charter and what the spending limit is, so the decision is not made under pressure.
Does film insurance cover flight delays and weather holds?
Not always. Cover varies between policies, so check whether yours includes weather-related delay, helicopter charter and evacuation. Our guide to film insurance and liaison officer requirements in Nepal explains what foreign productions need.
Plan for the weather before it plans for you
Buffers cost little compared with a stranded crew. If you are scheduling a shoot in the mountains and want a realistic view of the risks, get in touch with Icefall Productions. We will help you build a schedule that holds up when the weather does not.
