Domestic flights in Nepal and how to survive the delays

Almost every domestic cancellation in Nepal comes down to visibility, wind or aircraft availability, and the three interact.

Visibility is the dominant one. Nepal's short-runway mountain airports are flown visually. There is no instrument approach that lets an aircraft descend through cloud onto a sloping strip in a valley, so if the pilot cannot see the runway from a safe distance, the flight does not go. That is not caution or bureaucracy; it is the only way those airfields can be operated at all. Kathmandu has instrument approaches but is still limited on winter mornings when fog sits in the valley until the sun burns it off, typically clearing later in the morning and pushing the entire day's schedule back.

Wind is the second. Valley airstrips such as Jomsom develop strong and predictable up-valley winds from mid-morning. That is why the Pokhara–Jomsom flights are scheduled early and simply stop for the day once the wind arrives, rather than delaying into the afternoon. If your morning flight is cancelled at Jomsom, the realistic next opportunity is the following morning, not later the same day.

Aircraft availability is the third and least discussed. Nepal's domestic fleet is small, several routes are flown by a handful of aircraft, and a technical problem or a diversion in the morning cascades through every subsequent rotation. This is why a flight can be cancelled on a clear day: the aeroplane is somewhere else, stuck behind weather that has since cleared.

Monsoon adds a fourth factor from roughly June through September, when heavy cloud, thunderstorms and reduced visibility affect large parts of the country and mountain flying becomes unreliable for weeks rather than days. Winter fog affects the Kathmandu valley and the Terai from around December into February. Between them, the two reliable weather windows for domestic flying are the pre-monsoon spring and the post-monsoon autumn — which is exactly when everyone else is flying too.

One more operational point worth knowing: the Lukla route has in some peak seasons been operated from Manthali airport in Ramechhap rather than from Kathmandu, to reduce congestion at the Kathmandu airport. That turns a short flight into a flight plus a long pre-dawn road transfer. Check where your Lukla flight actually departs from before booking anything else around it.

Nepal has no equivalent of the European delay-compensation regime. There is no schedule of fixed payments for a cancelled domestic flight, and an airline that cancels for weather owes you nothing beyond your money or your seat.

What you are entitled to comes from two places. The first is the airline's own conditions of carriage — the contract you accepted when you bought the ticket — which will set out what happens on cancellation, normally a choice between rebooking on the next available service and a refund. The second is Nepal's consumer protection framework, which applies to services generally and gives you somewhere to take a complaint when an airline simply refuses to honour its own terms.

In practice, on a weather cancellation, airlines rebook you onto the next flight with a seat. The friction is that the next flight is often full, because the passengers booked on it are also waiting, and the backlog after a two-day weather closure at a popular airstrip can take days to clear. Priority in that queue is not always transparent, which is why passengers with the same ticket end up leaving on different days.

Ask specifically and in writing for one of three things: a confirmed seat on a named later flight, a full refund, or a written note of the cancellation. That last item is the one people forget and the one insurers ask for. A dated cancellation confirmation from the airline is worth more later than any amount of arguing at the counter.

If the airline cancels and refuses both refund and rebooking, or charges you again for a seat you already paid for, that is a consumer complaint rather than an aviation matter. The Department of Commerce, Supplies and Consumer Protection handles consumer complaints about services, and Nepal's consumer protection law is the relevant framework. Complaints about safety, licensing or an operator's conduct as an operator go to the Civil Aviation Authority of Nepal.

Do not expect meals, hotels or transfers as of right. Some airlines provide them on longer disruptions and some do not, and it is generally discretionary rather than owed. Budget for the possibility of paying for your own extra nights.

Put buffer days between a mountain flight and any international departure. Two is the working minimum in the trekking seasons and more in monsoon or deep winter. This single decision prevents almost every serious problem described in this guide.

Fly in the morning where you have a choice. On mountain routes the early slots are the ones that actually operate, and a mid-morning booking on a route that closes at eleven is a booking with a much lower chance of flying.

Book the domestic flight and the international flight on separate tickets knowingly, and understand what that means: no through-protection. If the domestic flight fails, the international carrier is not obliged to do anything for you. That is the trade-off for the flexibility of buying separately, and it is why the buffer days matter more than the ticket price.

Check the departure airport, not just the route. A Lukla ticket may depart from Manthali. A Pokhara flight may operate from the newer international airport rather than the old domestic one. Confirm with the airline within a few days of departure.

Take out travel insurance that specifically covers trip delay and missed connection, and read what it excludes. Many policies exclude delays that were foreseeable, and 'weather in Nepal in July' can be argued to be foreseeable. Cover for helicopter evacuation is a separate matter again and is dealt with in our trekking insurance guide.

Have a road plan for every flight. Kathmandu to Pokhara is a long but reliable drive. Kathmandu to Jomsom is not a realistic same-day alternative. Knowing before you travel which of your flights has a ground alternative and which does not tells you exactly where to put your buffer days.

Finally, keep your itinerary loose at the end rather than the start. A trip that is tightly scheduled in its first week and open in its last absorbs disruption. A trip that is loose at the start and tight at the end fails.

Domestic fares in Nepal are published by the regulator, and there is a long-established two-tier structure in which foreign nationals pay a different published fare from Nepali citizens on the same route. This is not an agent's markup and is not negotiable at the counter; it is how the fare table works. Nepali citizens should expect to show identification.

Buy from the airline directly or from an established agent with a physical office. Nepal's domestic airlines sell online and through agents, and the agent's value is mostly in rebooking you quickly when things go wrong, which is a real service when you are standing at an airstrip with no signal. The risk is the informal reseller who takes payment and issues nothing verifiable; ask for the ticket and check it against the airline's own booking reference.

Baggage allowances on domestic flights are low, well below what an international ticket allows, and excess is charged by weight. This matters most on trekking routes where people arrive from an international flight with a full-sized bag. Plan to leave what you do not need in Kathmandu or Pokhara — most hotels store luggage — rather than paying excess on a small aircraft that may refuse it anyway on a hot-and-high day.

Check-in closes early and is enforced. On small domestic airfields the aircraft turns around fast and the operator will not hold it. Being at a mountain airstrip an hour before the notional departure is normal practice, partly because flights sometimes go early when a weather window opens.

Do not treat the published schedule as a timetable in the European sense. Departure order at a mountain airstrip is often driven by which aircraft arrives and when the window is open, and passengers are called accordingly. This is why 'my flight is at nine' is a less useful sentence than 'I am at the airstrip and listening for my name'.

Finally, a word on safety, because travellers ask and deserve a straight answer. Nepal's airlines have been on the European Commission's air safety list — barred from operating into the European Union — since 2013, on the basis of concerns about the state's safety oversight rather than about any single operator. That listing is a matter of public record and is a reasonable thing to factor into your own decisions, alongside the fact that hundreds of thousands of people fly these routes every year without incident. CAAN publishes its safety policy and its oversight functions; read them and decide for yourself rather than relying on rumour.

Kathmandu to Pokhara is the most robust domestic sector in the country. Both ends have reasonable infrastructure, the sector is short, and there is a genuine road alternative that takes most of a day but always exists. If a schedule has to have a tight connection somewhere, this is the least bad place for it.

Kathmandu or Manthali to Lukla is the highest-risk sector most visitors will fly. Tenzing-Hillary airport at Lukla is short, sloping and surrounded by terrain, and it operates in the morning under visual conditions only. Cancellations run in blocks: a bad weather system closes it for consecutive days and creates a backlog that takes further days to clear. Everyone waiting is trying to get on the same limited seats. Helicopter charter exists as a fallback and is the reason a lot of people get out on time, but it is expensive, subject to the same weather, and has its own well-documented history of insurance abuse that has made insurers considerably more sceptical.

Pokhara to Jomsom is a short, spectacular, wind-limited hop with a hard daily cut-off. There is a road, but it is rough and slow and not a same-day substitute in most conditions. Treat the flight as morning-only and plan around a missed day rather than a missed hour.

Kathmandu to the Terai — Biratnagar, Bhairahawa, Nepalgunj, Janakpur, Bhadrapur — is generally more reliable than mountain flying, with winter fog the main seasonal risk at both ends. Road alternatives exist and are long but real.

Remote strips in the far west and the high Himalaya — Simikot, Dolpa, Taplejung and others — are the least predictable of all, served by few aircraft and often flown as part of a chain of sectors. Independent travellers on those routes should assume multi-day disruption is normal rather than exceptional, and should carry the food, cash and warm clothing to sit it out.

Across all of them, the pattern is the same: the risk is concentrated at the mountain end, the recovery is slow because capacity is small, and the only reliable protection is time you have deliberately reserved. CAAN publishes the list of domestic operators, the airports they serve and the domestic schedule, which is the right place to check what actually exists on a route before you commit to it.
