Why almost every Everest trek starts in Lukla
There is no road into the Khumbu. Tenzing-Hillary Airport at Lukla, 2,860 m, sits on a shelf above the Dudh Koshi and puts trekkers two days' walk from Namche Bazaar. Without it, the walk in from the nearest road head adds two to five days each way. Edmund Hillary had the airstrip built in the 1960s; it was named after Tenzing Norgay and Hillary in 2008.
The runway is 527 m long and slopes uphill at about 12 percent, with a wall at the top and a drop into the valley at the bottom. Planes land uphill and take off downhill, and there is no chance to abort a landing once committed. Only small short-take-off aircraft use it: the Twin Otter, Dornier 228 and Let L-410, with 14–19 seats, operated by Tara Air, Summit Air and Sita Air.
Kathmandu or Ramechhap: the peak-season rule
Tribhuvan International Airport in Kathmandu has a single runway shared by international jets and domestic flights, and in the busy trekking months the morning queue of Lukla flights became a serious bottleneck. Since 2019, Nepal's aviation authority has moved scheduled Lukla flights to Ramechhap (Manthali) Airport during peak periods, which in recent years have run roughly from late March to the end of May and from late September to the end of November. Check current status before you travel, because dates and rules are reset each season.
Ramechhap is about 130 km east of Kathmandu, reached by the Araniko Highway to Dhulikhel and the BP Highway towards Khurkot. The drive takes 4–5 hours outbound in the dark and 5–6 hours coming back in daytime traffic. Flights from Ramechhap to Lukla take about 20 minutes. Outside the peak months, and for helicopters at any time, departures from Kathmandu continue.
| Option | Time from Kathmandu | Typical cost | Good to know |
|---|---|---|---|
| Flight from Kathmandu | 35 min flight | ≈ US$220–250 one way (foreigners) | Off-peak months; early morning departures |
| Drive + flight via Ramechhap | 4–5 h drive + 20 min flight | Same fare plus road transfer | Peak months; 1–2:30 am pickup |
| Shared helicopter | 45–50 min | ≈ US$500–600 per seat | Flies when planes cannot; still needs visual weather |
| Jeep + walk via Salleri | 10–12 h drive + 1–2 days' walk | Low, but adds days | Avoids flights; tracks close in monsoon |
What a Ramechhap day looks like
On a Ramechhap departure, your driver collects you from your Kathmandu hotel between 1 and 2:30 am. The road is quiet at that hour, and most people sleep in the car. You reach Manthali before dawn and wait in a small terminal with basic toilets and tea stalls while airlines weigh bags and issue boarding passes. The first flights leave at around 6 am as light reaches Lukla.
The return leg is the harder one. You land at Ramechhap in the morning, often by 8 or 9 am, then face 5–6 hours on the road via Khurkot, the Sun Koshi valley and the slow climb through Dhulikhel and Banepa into Kathmandu, arriving by early afternoon if all goes well. Carry snacks, water and a warm layer, and do not book an international flight for the same evening.
- Pack a small bag with snacks, water, a headlamp and a warm jacket for the night drive
- Keep your passport and permits in your daypack, not in the checked duffel
- Expect basic facilities at Ramechhap; there is no lounge
- Toilets in Lukla and Ramechhap are simple, so carry tissues and hand gel
Weather delays and spare days
Lukla flights operate under visual flight rules, so pilots need clear sight of the valley and the runway. Cloud often sits in the Dudh Koshi gorge or over the passes between Kathmandu and Lukla in the early morning, and fog can close Ramechhap in winter. A typical delay is a few hours; a bad spell can cancel all flights for two or three days, leaving hundreds of trekkers waiting in Lukla.
Delays are worst in late May, the monsoon months and occasionally in late autumn when a storm passes. When flights are cancelled, airlines rebook passengers in order on the next flying day, so those already waiting go first. Keep at least one spare day before your international departure in October, November, March and April, and two or three in the shoulder and monsoon months. Our 14-day trek has a spare day built in for this.
Baggage limits and fares
The usual allowance on Lukla flights is 15 kg per person in total: about 10 kg checked and 5 kg hand luggage. Everything is weighed, including your daypack. Excess baggage is charged by the kilo and may be sent on a later flight if the plane is full, so leave city clothes and spare luggage at your Kathmandu hotel, which will store them for free or a small fee.
Fares for foreign passport holders are set in US dollars, about US$220–250 each way. Nepali citizens pay a lower rupee fare. Fares rise from time to time with fuel prices, and airlines add small charges for excess baggage. Tickets are issued through agencies or airline offices with passport details, and names must match the passport exactly. Our Everest packages include the flights, any Ramechhap transfers and the 15 kg allowance.
Tips for a smoother Lukla flight
Small habits make the Lukla flight much easier, whichever airport you leave from. Most of them are about time and weight, the two things that decide who flies first on a cloudy morning.
- Book the first or second flight of the day; later flights are the first to be cancelled when cloud builds
- Weigh your duffel and daypack at the hotel the night before, and keep the total under 15 kg
- Wear your boots and heaviest jacket on the plane to save weight in your bag
- Carry snacks and water in your daypack, because waiting areas at Lukla and Ramechhap sell little
- On the way back, reach Lukla the afternoon before and stay near the airport so you can board at short notice
- Keep your guide's phone number and the airline booking reference written down, not only on your phone
- Plan your last day in Kathmandu as a free day, not a sightseeing tour, until you have landed
Helicopter and overland alternatives
Helicopters are the main backup. A shared seat between Kathmandu and Lukla costs roughly US$500–600, and a private five-seat charter much more. Helicopters can fly in weather that grounds fixed-wing aircraft and avoid the Ramechhap drive, but they still need visual conditions and carry less weight at altitude, so they are a better bet rather than a guarantee. Insurance rarely covers a helicopter used to avoid a delay, only one used for rescue.
The overland option suits trekkers with time or a strong dislike of small planes. Jeeps run from Kathmandu to Salleri or Phaplu in Solu, about 270 km and 10–12 hours, and continue on rough tracks towards Thamdanda or Surke when they are open. From there you walk 1–2 days to the main trail near Lukla, passing Sherpa and Rai villages that few trekkers see. Monsoon landslides often close the upper tracks, so check current status before you travel.

Questions travellers ask
Do Lukla flights leave from Kathmandu or Ramechhap?
Both, depending on the season. In recent peak periods, roughly late March to May and late September to November, scheduled Lukla flights have operated from Ramechhap (Manthali), 4–5 hours by road from Kathmandu. At other times they leave from Kathmandu. Helicopters fly from Kathmandu all year. Check current status before you travel.
How far is Ramechhap from Kathmandu?
Ramechhap (Manthali) Airport is about 130 km east of Kathmandu by road, via Dhulikhel and the BP Highway. The drive takes 4–5 hours in the early morning and 5–6 hours on the way back in daytime traffic. For a morning flight to Lukla, pickup from Kathmandu is usually between 1 and 2:30 am.
What is the baggage limit on Lukla flights?
Usually 15 kg per person in total, about 10 kg checked and 5 kg hand luggage, including your daypack. Bags are weighed at check-in and excess is charged by the kilo; it may travel on a later flight. Leave non-trekking clothes at your Kathmandu hotel. Our porters carry up to about 10 kg per trekker on the trail.
How often are Lukla flights delayed?
Short delays of an hour or more are common in every season, because flights need clear visual weather at Lukla and on the route. Full-day cancellations happen several times a month in spring and autumn and much more often in late May and the monsoon. Keep at least one spare day before your international flight, more outside peak months.
What happens if my Lukla flight is cancelled?
The airline rebooks you on the next flying day, usually in order of the original booking, at no extra fare. You pay for the extra night and meals in Lukla, or in Kathmandu if you have not left yet. If delays run long, many trekkers share a helicopter at roughly US$500–600 per seat. Our guides handle the rebooking for you.
Is it scary to land at Lukla?
Many travellers find it exciting rather than frightening. The plane flies close to the hills on the approach, then lands on a short uphill runway and stops within seconds. Sit on the left side flying to Lukla for mountain views. Pilots fly only in clear weather and train specifically for the airport, which is why delays happen.
Can I fly to Lukla by helicopter instead?
Yes. Shared helicopter seats between Kathmandu and Lukla cost roughly US$500–600 and take 45–50 minutes, avoiding the Ramechhap drive and the plane queue. A private charter costs more. Helicopters still need visual weather, carry limited baggage and may wait for enough passengers. We can add a helicopter leg to any Everest package.
Which side of the plane should I sit on to Lukla?
Sit on the left side flying from Kathmandu to Lukla and on the right side flying back, for views of the Himalaya from Langtang and Gauri Shankar east to Numbur and, on clear days, the Everest group. Seats are not assigned on most Lukla flights, so board promptly. From Ramechhap the flight is shorter, but the same sides apply.
How much is a Lukla flight for Indian passport holders?
Fares for foreign passport holders are quoted in US dollars, about US$220–250 each way. Whether Indian nationals pay that dollar fare or a lower rupee fare has varied by airline and over time, so ask when you book and check current status before you travel. Our INR package prices include return flights and Ramechhap transfers, so there is nothing extra to book.
