Sorry if this is a newbie question (this is my first interesting miles redemption) - but would you mind telling me if the following would work for a single award?

I'm looking to fly from either ITM or KIX, would like to have a long transfer in KTM, and then end up in SHJ or AAN (or somewhere around there like DXB).

From the AA award chart it looks like I should be able to go from Asia 1 to the Middle East for 30k one way in business class. And I've checked BA.com for award seat availability in business on flights KIX-HKG-KTM (14 hour overnight layover) KTM-DOH-SHJ. Looks like the airlines would be Cathay Pacific/Dragonair, and Qatar Airlines.

Will I have trouble getting this routing booked? Any suggestions for modification? I'm not totally clear on the rule about length of transfer either. There are three KTM-DOH flights per day - do I have to take the earliest one the next day after I arrive or can I take a later one as long as I leave within the 24 hour window?

Thanks!
