Add at least one spare day, and two if your international flight home is hard to change. Lukla flights are the least predictable part of the trip, and a buffer protects your connection.
Why you need a buffer
Lukla flights depend on weather and are often delayed or cancelled. A standard 14-day plan has no spare day, so one delay can eat into your onward travel. See the plan B guide.
How many days
One spare day is the minimum. Two is safer in busy months, or if you must be back by a fixed date. An extra day can also be used for altitude if you feel poorly. See how many days to allow.
Where to put the days
Put one in Kathmandu after the trek, before your flight home. Do not book the international departure for the day after your Lukla return. A spare day at Namche or Dingboche helps the body adjust. See the acclimatisation plan.
What it costs
Extra nights in Kathmandu or Lukla are usually paid by you. Insurance may cover some delay costs, depending on your policy. See who pays when flights are delayed.
A sample buffer plan
A sensible plan adds one spare day at the end in Kathmandu and, for tight schedules, a second day on either side of the Lukla flights. If everything runs on time you gain a free day to explore the city. If the weather closes the airport, you keep your onward flight.
Buffer days versus rebooking
Rebooking an international flight after a missed connection can cost much more than an extra hotel night. Think of the buffer as insurance. It is cheapest when planned in advance and most expensive when added in a crisis.
Protecting your flight home
Choose a flexible fare or leave a gap. Keep your insurance papers handy and tell your operator your fixed dates when you book.
How to use a buffer day
If you do not need the spare day, use it for a rest in Namche or a short hike. It improves the trek and reduces risk.
