Hi Rickster,
Flights are included in the price of this holiday.
To explain a little, there is a point where we have to return unsold flight seats to the airline. It appears this has happened for this tour. If you were to book online or speak to one of our agents, your booking would go "on request" which means that a place is held for you while we try and buy back the flight seats.
If you haven't already done so, I would recommend that you talk to one of our holiday advisors who will be able to look into this for you.
Kindest regards,
Julia
