Hi I have just returned from the trip to Nepal. Whilst we were there our tour manager put us in touch with the agent from Yeti Airlines , who came to the hotel and took bookings from 12 of the 17 in the group. The cost was £173 , including transport to and from the hotel, window seat, glass of champagne, and it was agreed by all that it was well worth the money. The flight is obviously weather dependent, so there is a possibility that it can be cancelled at the last minute, but we had a clear morning and saw wonderful views of the Himalayas and of course Everest.
