Why Lukla flights leave from Ramechhap (Manthali) in the main seasons, what the 2 am drive is like, which airlines fly, the 15 kg baggage limit, how weather delays really work, how many spare days to keep, helicopter sharing, and the walk-in alternatives from Salleri, Phaplu and Jiri.

Lukla flights are the short hop that starts almost every Everest trek: a 20 to 40 minute flight in a small twin-engine plane to Tenzing-Hillary Airport at about 2,845 m. In the main autumn and spring seasons, scheduled Lukla flights leave from Ramechhap Airport at Manthali, a four to five hour drive from Kathmandu, not from Kathmandu itself. Outside those windows they usually fly from Kathmandu's domestic terminal.
The flight is the one part of an Everest trip nobody controls. It needs clear weather at both ends, and cloud can stop it for a morning, a day, or now and then most of a week. Keep at least one spare day at the end of your trek and, if you can, a second before your international flight home. Every Everest itinerary we run has one built in.
If you are still choosing a route, our Everest Base Camp trek guide covers the trek itself. This article goes deeper into the flight: where it leaves from, what the day feels like, what goes wrong and how to plan so that it doesn't wreck your trip.
To take pressure off Tribhuvan International Airport in Kathmandu, which has a single runway shared by international and domestic flights. The Civil Aviation Authority of Nepal (CAAN) moves the busy Lukla route to Manthali in the peak trekking months. Lukla is one of Nepal's busiest domestic sectors, and dozens of small planes queuing for the main runway each morning caused long holds.
The arrangement first ran in 2019 while Kathmandu's runway was being resurfaced, stopped during the pandemic, and returned in late September 2022. It has been repeated every main season since. Manthali is a small district town in the Tamakoshi valley, and its airport sits at about 474 m, so it is warm, low and often clear when Kathmandu is hazy.
For autumn 2026, Manthali–Lukla flights began on Asoj 13 in the Nepali calendar, which is 29 September, and are scheduled to run until Mangsir 15, around 1 December. In spring the Manthali season runs from Chaitra to Jestha, roughly mid-March into late May or early June.
Those are the published windows, not a promise for every single day. A few flights from Kathmandu sometimes run in the shoulder weeks, charter and helicopter flights still use Kathmandu, and the exact start and end dates are set each season. We confirm which airport your flight uses a few days before you fly. When it is Manthali, the private transfer is already included on our Everest Base Camp, Gokyo Lakes, Three Passes and Everest View treks.
From Ramechhap (Manthali) | From Kathmandu | |
|---|---|---|
When | Main autumn and spring seasons | December to February, June to September, some shoulder days |
Getting to the airport | Private transfer, about 132 km, four to five hours | Short drive from your hotel |
Hotel pick-up | Around 1 to 2 am | Around 5 to 6 am |
Flight time | About 20 minutes |
You leave Kathmandu in the dark, usually between 1 and 2 am, and drive about 132 km east through Dhulikhel and down the BP Highway towards the Sunkoshi, then north to Manthali. Allow four to five hours. The road is paved most of the way but winding, so if you get carsick, take something before you leave and sit in the front.
Here is how the morning usually goes. Your guide meets you in the hotel lobby with the vehicle. Most people doze for the first couple of hours. You stop for tea at a roadside place somewhere along the river, and you reach Manthali as it gets light, with time to check in for the first flights at around 6 to 7 am. Flights are boarded in waves, so you may wait an hour or two in the small terminal even on a good day.
Manthali has a handful of hotels and guesthouses near the airport. If the forecast is poor, or your group has arrived in Kathmandu late, we sometimes drive down the afternoon before and sleep in Manthali, which turns the 1 am start into a short walk to the terminal.
Three airlines fly scheduled services to Lukla: Tara Air, Summit Air and Sita Air. They use short take-off aircraft, mostly the Twin Otter, Dornier 228 and Let L-410, carrying about 15 to 19 passengers. On a good-weather day in the main season the three airlines between them run up to around 60 flights from Manthali.
You do not usually choose the airline yourself on a guided trek. We book the earliest available flights, because morning departures have the best chance of going. All three run broadly the same service, at broadly the same fares, from the same small terminals. Helicopter companies also fly between Lukla, Manthali and Kathmandu, which matters if your plane is grounded (see below).
On the way to Lukla, the left-hand side of the plane has the mountain views. Coming back, sit on the right. Seats are not usually assigned on these flights, so the side you get depends on when you board. Even if you miss out, the view of the cockpit and the runway rising towards you on the approach is the part most people remember.
Usually 15 kg per person in total: 10 kg of checked baggage plus 5 kg of hand luggage. The limit is the same across the three airlines. Excess baggage is charged by the kilo when there is room for it, and on a full plane it may simply be left behind and sent on a later flight. Every bag, including your daypack, gets weighed.
The plane's payload is tight, so the limit is enforced more strictly than on big airlines. On our treks a porter carries your main bag on the trail (about 10 kg per trekker), so the 10 kg checked limit and the porter load line up nicely. Whatever you don't need on the trek stays at your Kathmandu hotel.
Wear the heavy things: boots, down jacket and fleece on the plane.
Keep with you: passport, permits, cash, medicines, phone, power bank, water, snacks, a warm layer.
Don't pack in your checked bag: spare batteries and power banks must travel in hand luggage.
Leave behind: city clothes, laptop, gifts and anything you will not use above Lukla.
Our Nepal trekking packing list is built around this limit.
Lukla is a visual-flight airport with no instrument approach, so pilots must be able to see the runway. Flights only go when there is clear weather at Lukla, at the departure airport and along the route. Mornings are usually calmest. By late morning the wind in the Dudh Kosi valley often picks up and flights stop, even on a sunny day.
That gives the day its rhythm. Everyone arrives early. If Lukla reports cloud, the airlines hold and wait for it to lift. Sometimes it does by 9 or 10 am and the backlog flies in a rush. Sometimes it doesn't, and by midday the airlines call it off for the day. You go back to your hotel in Manthali or Kathmandu and try again the next morning.
The return works the same way from Lukla. Your guide checks you in at the airline counter the afternoon before, and you walk to the airport from your lodge after an early breakfast. If the plane can't get in, it can't take you out either.
No official statistics are published, so beware of anyone quoting a precise percentage. In practice, a delay of a few hours is normal, a lost day happens regularly in every season, and a run of several days with few or no flights happens most years. In the monsoon, poor visibility closes the airport about half the time.
Two examples show how bad it can get. In October 2022 hundreds of trekkers were stuck at Ramechhap after days of bad weather. In October 2024, after about a week of cancellations, airlines and helicopters flew more than 1,150 waiting trekkers into Lukla in a single day once the weather cleared, while hundreds more flew out.
Season | What usually happens |
|---|---|
October–November | The most reliable months. Clear mornings are the norm, but early-season cloud and the odd storm can still cause short shutdowns. |
March–May | Good, with more haze and afternoon cloud. Late spring brings more lost mornings. |
December–February | Often clear and stable, though cold, and fog can sit in the valleys. |
June–September | Monsoon. Frequent cancellations, often for days at a time. |
A little, at the departure end. Manthali is low and usually clear early, while Kathmandu can be hazy or foggy in the morning. But most delays are caused by weather at Lukla, which is the same whichever airport you leave from. The shorter flight means planes can do more rotations when the window opens, which helps clear a backlog faster.
Keep at least one spare day after the trek, and ideally a second before your international flight home. Our Everest Base Camp trek has a contingency day on day 14 of 15, the Gokyo Lakes trek on day 13 of 14, the Three Passes trek on day 19 of 20, and the Everest View trek a spare day at the end.
If your flight out of Lukla runs on time, the spare day becomes a free day in Kathmandu for sightseeing, shopping or a long lunch. If the flight is delayed, the spare day absorbs it and your international flight is safe. The risk is on the way back, not the way in: a delay at the start of the trek just pushes everything on by a day, and we can usually recover that on the trail or in the contingency day.
You wait in Kathmandu or Manthali and fly on the next available morning, and we shift the trek by a day. On longer delays we look at the itinerary with you: shortening a side trip, using the contingency day, or moving to a helicopter. We won't cut an acclimatisation day to catch up, because that is what keeps the trek safe higher up.
Extra hotel nights and meals caused by flight delays beyond the contingency day are not included in our trek price, so keep a little budget aside. Some travel insurance policies pay out for travel delay; read yours before you go. Our article on travel insurance for trekking in Nepal covers what to look for.
Yes. Helicopters fly between Lukla and Kathmandu or Manthali whenever weather allows, and they can fly in conditions that ground the planes, because they can pick a route under the cloud. A shared seat commonly costs around USD 450 to 550 one way in the main seasons, and a whole helicopter roughly USD 2,000 to 3,000.
Helicopters are not immune to the weather, though. If cloud sits right down on Lukla, nobody flies. And they are the first thing everyone reaches for after a long shutdown, so seats get scarce exactly when you want one.
A helicopter such as the AS350 B3 carries about five passengers, with a total weight limit that falls as altitude rises. Helicopter companies sell the seats individually and fly once the aircraft is full, so you share with other trekkers heading the same way. Your guide or our office arranges it and tells you the time to be at the helipad.
You pay per seat, usually in cash or by card in Kathmandu, and the price depends on season and demand.
Weight matters more than on the plane. Expect a strict limit on bags, often less than the 15 kg plane allowance.
You may fly to Kathmandu or to Manthali, depending on where the helicopter is based that day.
A helicopter for convenience or to avoid a delay is your own cost. Insurance pays for a helicopter only for a medical evacuation.
On our treks helicopter flights chosen to avoid delays are not included in the price, but we can arrange them quickly because your guide is already at the airport talking to the operators.
Lukla is a demanding airport, and flights only operate in conditions set by CAAN for that reason. The runway is 527 m long with an 11.7% slope, there is no go-around once a plane is committed to land, and only pilots with specific short take-off experience and supervised Lukla landings may fly there. Thousands of trekkers fly in and out every season without incident.
It has had serious accidents. The deadliest at Lukla was in October 2008, when a Yeti Airlines Twin Otter crashed on approach in poor visibility and 18 people died. In 2017 a cargo flight crashed just short of the runway, killing its two pilots, and in April 2019 a plane veered off the runway on take-off and struck a parked helicopter, killing three people. In 2012 a Sita Air flight bound for Lukla crashed shortly after take-off from Kathmandu, with 19 deaths.
What keeps the risk down is the same thing that causes delays: flights don't go in doubtful weather. That is why we never push for a flight in marginal conditions, and why patience in the terminal is part of a safe trip.
Not from the flight itself. You land at about 2,845 m and walk downhill to sleep at Phakding at 2,610 m, which is a gentle first night. The real altitude test begins above Namche Bazaar. Our altitude sickness guide explains how our itineraries build height slowly.
Yes. You can drive to Salleri and Phaplu or to Jiri and walk in to the Khumbu, the way expeditions did before Lukla airport opened. It adds days but removes the flight risk on the way in, and helps you acclimatise. Most people still fly out from Lukla at the end, because walking back the same way adds several more days.
The road from Kathmandu to Salleri, the district headquarters of Solukhumbu, takes about eight to twelve hours. From there a rough jeep road now runs north towards Surke, a short walk below Lukla, though how far a jeep can get depends on the season and recent landslides. Phaplu, next to Salleri, has a small airstrip with occasional flights.
If you jeep part of the way and walk the rest, through Sherpa and Rai villages such as Ringmo, Nunthala, Kharikhola and Bupsa, you reach the main Everest trail at Surke or Chaurikharka in two to four days. The trail is quiet, with simple lodges, and the extra days at lower altitude are good preparation.
Jiri is the classic start, about a seven to eight hour drive east of Kathmandu, and the walk from there to Lukla or Phakding takes about six to seven days. The route crosses ridges and rivers through Shivalaya, Bhandar, the Lamjura La at about 3,530 m and the Sherpa village of Junbesi, before joining the Salleri route.
It is a lot of up and down, through farmland and rhododendron forest, and by the time you reach the Dudh Kosi you are fit and well acclimatised. It suits trekkers with three weeks or more who want to see the lower hills as well as the high mountains.
Neither walk-in is a standard trip on our site, but we can plan either as a private trek. Tell us your dates and we will suggest the best combination of road, trail and flight.
All four of our Everest region treks start and finish with the Lukla flight, and each includes the Manthali transfer when it is needed and a spare day at the end. Pick by how much time you have and how high you want to go.
Trek | Days | High point | Spare day |
|---|---|---|---|
8 | Hotel Everest View, 3,880 m | Day 8 | |
14 | Gokyo Ri, 5,357 m | Day 13 | |
You can buy tickets directly from the airlines or through a travel agent in Kathmandu. On a guided trek we book the flights, permits and Manthali transfer together, so that if the flight moves we can move everything else with it. Most trekkers find it simpler to let the trekking company handle flights, because rebooking after a delay is much easier from the inside.
Yes. Domestic flights in Nepal check your passport at the terminal, and your permits are tied to your passport details. Keep it in your daypack, not your checked bag.
There are basic toilets and small tea shops next to the terminal, selling tea, coffee, biscuits and simple snacks. Bring your own toilet paper and some food in case you wait for several hours.
The first flights usually leave Lukla in the early morning, often around 6.30 to 7 am, when the weather is clear. Your guide checks you in at the airline office the afternoon before and tells you when to be at the airport, which is a few minutes' walk from most lodges.
On the return, your main bag is checked in with you and may come on the same flight or the next one if the plane is at its weight limit. Keep anything you need that day in your daypack, so a bag on the next flight is only an inconvenience.

Yes. Some trekkers fly back by helicopter from Gorak Shep or Pheriche to save the descent days. It is your own cost unless it is a medical evacuation covered by your insurance, and the weight limits are tighter at altitude.
From December to February and June to September, Lukla flights normally leave from Kathmandu. Winter mornings are often clear but cold. In the monsoon, cancellations are frequent and can last days, which is why we don't recommend Everest treks then.
Only occasionally. For autumn 2026 the airlines published a small weekly Kathmandu–Ramechhap schedule meant mainly for local passengers, and it runs only when there are enough bookings. For trekkers, the road transfer remains the reliable way to reach Manthali.
The airlines schedule flights every day, weather permitting, including public holidays. Whether they actually fly depends on the morning weather at both airports.
Stay close to your guide and the terminal until the airline cancels for the day, as windows open quickly. Keep warm layers, water, snacks, a book and a charged power bank with you. Once flights are called off, your guide sorts out the next morning's booking.
