Tenzing-Hillary Airport
Lukla is a Sherpa trading town at 2,860 m, built around Tenzing-Hillary Airport, a single 527 m runway sloped at roughly 12 degrees and approached over a cliff edge, named for the two climbers who made Everest's first ascent in 1953. Most spring and autumn flights now depart from Manthali Airport rather than Kathmandu directly, landing at Lukla after a roughly 30-minute STOL (short takeoff and landing) flight.
Why nearly every itinerary starts here
Flying to Lukla cuts a full week off the historic overland approach from Jiri, which is why 10 of the 11 itinerary variations on this site begin or end at this airstrip rather than walking in. The trade-off is a real cancellation and delay risk, roughly 30 to 40% of scheduled flights on a given peak-season day, driven by cloud cover and wind at the sloped, one-directional runway; no single authority publishes a reliable year-ahead figure, so treat this as a planning range, not a fixed statistic.
The town itself
Lukla feels like a genuine small town compared to the trail villages above it: gear shops, bakeries, pharmacies, and lodges cluster along the single main street leading from the airstrip gate toward the trailhead. Most trekkers pass through twice, once landing at the start of the trek and once departing at the end, rather than spending real time here.
Alternatives to flying in
Trekkers who want to avoid Lukla's flight risk entirely have two real options: the historic Jiri Route, walking in from the lower Solu-Khumbu roadhead over roughly eight additional days, or the By Road itinerary via Salleri and Thamdanda. Both rejoin the standard trail at Phakding or Namche Bazaar.
Departure day logistics
The flight out of Lukla at the end of a trek carries the same cancellation risk as the flight in, which is why every well-planned itinerary builds at least two unscheduled buffer days into the Kathmandu schedule, ideally positioned after the return flight rather than before departure.
How the airport was actually built
Tenzing-Hillary Airport was constructed in 1964 under Sir Edmund Hillary's direction, funded and organised through the Himalayan Trust, the foundation he set up to support Sherpa schools and hospitals in the region. Hillary originally wanted flat farmland for the runway, but local farmers refused to sell, so the strip was built on its current sloped site instead, purchased from Sherpa landowners for roughly USD 2,650. Hundreds of local porters moved the earth by hand, entirely without machinery. The airstrip stood unused for seven years, only becoming operational in 1971, and its runway wasn't paved until 2001. It carried the name Lukla Airport until 10 February 2008, when Nepal's government officially renamed it Tenzing-Hillary Airport to honour Everest's first two summiteers.
