The ascent via the southeast ridge begins with a trek toBase Camp at 5,380 m(17,600 ft) on the south side of Everest in Nepal. Expedition members usually fly into Lukla (2,860 m) from Kathmandu and pass through Namche Bazaar.
Fly to Lukla Airport from Kathmandu. There are several airlines operating dozens of flights everyday. Among them, Tara Air and Agni Air are generally considered the most reliable airlines plying the route. Sita Air also operates two flights every morning from Kathmandu to Lukla at 07:00 and 08:20. The flight takes around 25 minutes. During the summer rainy season, there may be substantial delays of flights, even a wait of one week is not unheard of. For the return journey, the flights leave Lukla at 07:40 and 09:00. Helicopter charter service is also available on demand and mostly used for rescue operation. Beware that airline safety regulations in Nepal are poor, and there is a chance you may get involved in a plane crash.
Alternatives are to fly to Phaplu airport, 2-3 trekking days south of Lukla, or to walk in from Jiri, which is 5-7 trekking days west of Lukla. These alternatives take more time and therefore are less popular, but are very peaceful and pleasant – and much safer than flying into Lukla.
Just after the village of Monju, there is check point for entering the Sagarmatha National Park. You will need to show your passport and pay a 3,000 Rs entry fee
