Another daft question..when trying to book an awards flight, how many stops can you have in the ticket?

I cant seem to get EX-Fra or EX-LHR and get Kuala Lumpur (4 langkawi) and Hong Kong in the same iteniery. Been checking flights to try and get start journey in zone 2, but apart from FRA i cant get flights from Glasgow. Pity EK not on *A, would have been much easier.

Any advice?

Thanks
