I hope this is not a confusion. I recently bought round-trip tickets from landlocked travels from US to Nepal, and I am in Nepal now with that ticket. I had no issues contacting them and had no problems with my tickets.

Matahoni - I am a bit curious when you say that they got you reservation and not actual ticket. What do you mean? The airlines only makes the reservation anyways. You get the boarding pass (if that is what you mean by actual tickets) when you go to the airport on the day of travel. Were your reservations cancelled without notifying you? How did you even know if the reservations were invalid? Did you go to the airport on the way of the travel and they turned you back?

Just want to add that I have no vested interest in defending Landlocked travels. But I have been their costumer and I want to make sure they don't get lynched due to some confusion.
