The Manthali (Ramechhap) Airport Situation: A Complete 2026 Guide

Almost every Everest Base Camp guide mentions Manthali in a single sentence and moves on. This is the complete version: since 2019, Nepal's Civil Aviation Authority has redirected most spring and autumn Lukla flights away from Kathmandu's Tribhuvan International Airport to Ramechhap Airport (IATA: RHP), also called Manthali after the town it serves, 132 km east of Kathmandu in the Tamakoshi river valley. Manthali Airport is a domestic-only airstrip that exists almost exclusively to relieve pressure on Tribhuvan's single, over-committed runway during the two Everest trekking seasons.

The Manthali relocation is a seasonal rerouting of scheduled Lukla flights, active roughly mid-March to mid-May and late September to late November, that trades a longer, earlier ground transfer for materially fewer weather-related cancellations once in the air.

Why Kathmandu stopped being the departure point

Tribhuvan International Airport handles Nepal's entire international and domestic traffic on one runway. During peak trekking season, prioritising internationally scheduled jets pushes small STOL (short takeoff and landing) aircraft like those flying to Lukla down the queue, creating exactly the kind of backlog covered in the Lukla flight cancellation guide. Shifting Lukla-bound traffic to Ramechhap's dedicated domestic strip removes that queuing conflict entirely: Ramechhap's mountain-facing visual flight window tends to open earlier and stay clearer for longer than Kathmandu's, letting all three operating airlines run multiple back-to-back rotations in a single morning.

What the morning actually looks like

Trekkers typically leave their Kathmandu hotel between 1:30 and 2:00 AM for the 4 to 5 hour drive east on the BP Highway, a winding mountain road that makes the 132 km distance far slower than it sounds on a map. Some operators arrange an overnight stay in Ramechhap itself the night before instead, trading the pre-dawn wake-up for a less comfortable overnight stop closer to the airstrip. Either way, this affects virtually every standard spring and autumn Everest Base Camp booking; it is the default, not an edge case.

The flight itself, once airborne, is short: 15 to 20 minutes from Ramechhap to Lukla, versus roughly 25 minutes on the rare Kathmandu-direct departures still occasionally scheduled outside peak windows.

Who operates the route

Three airlines fly the Ramechhap-Lukla corridor: Tara Air, Summit Air, and Sita Air, using small twin-engine STOL aircraft, principally the Twin Otter DHC-6, the Dornier 228, and the Let L-410. All three operate under the same visual-flight-rules constraints, so weather affects every carrier equally; switching airlines doesn't meaningfully change your odds of a delay.

Cancellation risk doesn't disappear at Ramechhap

Even from Manthali, Lukla flights still face a 30 to 40% daily cancellation or delay rate in peak season, since the limiting factor is cloud and wind at Tenzing-Hillary Airport's Lukla end, not the departure airport. Building at least two buffer days into your Kathmandu schedule, ideally at the trip's end, remains standard risk management for the whole route regardless of which airport you depart from. See the full guide to what happens if your flight is cancelled for the rebooking process itself.

Three ways to avoid Manthali logistics entirely

Trekkers who'd rather skip the pre-dawn drive altogether have three real alternatives: charter a helicopter directly from Kathmandu, from roughly USD 1,200 per person shared four ways, drive the Salleri and Thamdanda road route and trek in from there on the By Road 18-Day itinerary, or walk in from Jiri on the same approach Hillary and Tenzing used in 1953, covered on the Jiri Route 21-Day itinerary.
