Thanks, I've tried everything online that I can think of. It's difficult for me to call at the moment, but I will try next week. However, I won't be booking the ticket, the client will, using their travel agent. They are quite happy with the longer, cheaper multi-stop flight. If I want the shorter, more expensive, flight, I have to argue my case and prove that this is a standard route with availability, but I guess it's not, so I'm probably out of luck anyway.
