Lukla Flights and Ramechhap: How It Really Works

Lukla's airstrip was built in 1964 by Edmund Hillary and the Sherpas he worked with, to bring in materials for the schools and hospitals of the Himalayan Trust. Before that, everyone walked in from the Kathmandu Valley or from the south. Local people say Hillary bought the land from Sherpa farmers and the runway was levelled by villagers stamping it flat while dancing, a story told often in Lukla. The airstrip was renamed Tenzing-Hillary Airport in 2008 in honour of the two men who first climbed Everest.

The runway is short, about 527 m, and sloped at roughly 12 percent, uphill for landing and downhill for take-off. One end stops at a mountain wall, the other drops to the valley. There is no room for a second attempt once a plane commits to land, so pilots fly only by sight, in clear weather, and only small short-take-off aircraft, mostly Twin Otters, Dornier 228s and Let L-410s with about 14 to 19 seats, use it. The airport sits at about 2,845 m, just below Lukla's lodges.

For years all Lukla flights left from Kathmandu's Tribhuvan International Airport. As tourist traffic grew, the congested airport struggled to handle dozens of small Lukla flights each morning, and from 2019 the authorities moved most Lukla flights in the peak seasons to Manthali Airport in Ramechhap district, south-east of Kathmandu. In recent years this has applied roughly from April to May and October to November, and sometimes beyond. Check current status before you travel.

Ramechhap is about 130 km from Kathmandu, a four-to-five-hour drive on a winding road. Because Lukla flights leave from first light, you normally leave your Kathmandu hotel around 1 or 2 am in a private car or shared jeep, arriving at Ramechhap before dawn. The flight from Ramechhap to Lukla is shorter, about 20 minutes. On the way back, you land at Ramechhap and drive four to five hours to Kathmandu, arriving early afternoon if all goes well.

Ramechhap is a small airport with simple facilities: a few tea shops, basic toilets and a crowded waiting hall at peak times. Bring snacks, water, a warm layer for the pre-dawn wait and a book. If flights are delayed by cloud at Lukla, you may wait there for hours.

Lukla flights operate under visual flight rules: the pilots must see the ground and the runway the whole way. Cloud at Lukla, at Kathmandu or Ramechhap, or along the route over the passes stops flights, even when the sky above your head looks fine. Mornings are clearest, so flights run from first light until the cloud builds, often by late morning. In the monsoon, from June to September, cloud often sits in the valleys for days, and cancellations are frequent.

Delays work in batches. Each aircraft flies several rotations a morning, so if the first rotation is delayed by two hours, everyone behind it is delayed too, and some flights may be pushed to the next day. Airlines usually honour your ticket on the next available flight, with priority to the earliest booked. Neither airlines nor agencies can make the weather clear, and pressure on pilots to fly in poor conditions is the one thing everyone in the Khumbu wants to avoid.

The usual baggage allowance on Lukla flights is 15 kg per person in total, normally split as about 10 kg checked and 5 kg hand luggage. Extra weight is charged per kilo if there is space, and in busy weeks it may be sent on a later flight. Pack your porter duffel to 10 kg and leave the rest at your Kathmandu hotel, which every trekking hotel will store for free.

Fares for foreigners have been around USD 200 to 230 each way in recent seasons, higher than for Nepalis, and are usually included in trek packages. Ramechhap fares are a little lower but you add the road transfer. On the flight in, sit on the left side for the Himalaya to the north: on clear mornings you may see Langtang, Gauri Shankar and then the Khumbu peaks as you approach Lukla. On the way back, sit on the right.

When you land, staff unload bags onto a small yard beside the terminal and you collect your own. Your guide meets the porters here, usually over tea in a lodge a few steps from the runway, while the bags are reweighed and loaded. Before leaving town you pass the counter where the Khumbu municipality permit is checked or sold, so keep your passport handy. Then the trail starts at the stone arch at the top of the village.

Helicopters can fly in weather that grounds fixed-wing aircraft, because they can follow the valleys more slowly and land without a runway. When flights have been cancelled for a day or two, helicopter operators sell seats between Lukla and Kathmandu or Ramechhap. Prices depend on fuel, demand and how many passengers share; in recent seasons a shared seat has typically cost several hundred US dollars per person, more when demand is high.

Helicopters still need some visibility, so they do not solve every delay. Insurance may pay for a helicopter if you are ill or injured, but usually not for weather delays alone, unless your policy explicitly covers missed connections. Check your policy before you leave home.

Our rule is simple: keep at least one spare day in Kathmandu after any Lukla trek, and two in the monsoon or winter. If you are flying home the day after landing from Lukla, you are gambling with an international ticket. On the way in, a one-day delay can be absorbed by shortening a trek or using a rest day, but on the way out there is no shortcut except a helicopter.

If your spare day is not used, it becomes a free day in Kathmandu: Boudhanath, Patan, a long lunch, a massage for tired legs. Most trekkers are glad of it either way.

• Book the earliest flight of the day if you can; early flights are least affected by cloud.
• Keep one to two spare days after the trek, especially from December to February and June to September.
• Pack to 15 kg total, with 10 kg in the porter duffel.
• Carry snacks, water and a warm layer for the airport wait, especially at Ramechhap.
• Keep valuables, medicines and a change of clothes in your hand luggage.
• Check whether your insurance covers helicopter transport for delays as well as emergencies.

You can avoid the flight in entirely by walking in from the south. From Phaplu or Salleri in Solu, reached by road in about nine to eleven hours from Kathmandu, the old trail through Junbesi, Ringmo, Nunthala, Kharikhola and Paiya reaches Lukla in five to six days. From Jiri, further west, the walk takes a few days more. Jeep tracks are slowly reaching more of these villages, and the routes change. The walk-in acclimatises you naturally and shows you the Solu villages that most trekkers fly over. You can then fly out from Lukla, which is easier to plan for than the flight in.
