If you are trekking from Lukla, your guide will most likely meet you at Lukla itself. If you would like your guide to accompany you on the helicopter ride, you must charter the helicopter. It may be possible for you to pay for a seat for your guide on a regular, non-chartered flight. But this will be subject to availability, and there will be no cost reduction. Tourists have priority over the seat. Please discuss this with us well ahead of your arrival in Nepal.
