My original plan was to use the AA ATW desk do the booking, and have a SABRE enabled TA in Cairo do the ticketing then send the ticket to me. AA has told me that if BA is the 1st segment, then a SABRE reservation is not going to work and it would be better to use BA directly. </font>
There's no (technical) reason why you shouldn't be able to go with your initial plan. I had a reservation ex-UK which was priced for me by the AA RTW desk (via tariff in Dublin), and ticketed by the AA CTO in London. The first segment was on BA and the first intercontinental segment was on QF.
