Am I correct that if I ticket through BA I will incur YQ fuel surcharge "taxes" that I won't incur if I book through AA?

As far as booking ex-CAI, if I book on-line through the oneworld site, who is the ticketing carrier in Cairo?

If it is not AA, is there any advantage to having the AA RTW desk in the States book the itinerary and send it over to the AA [contract] ticket office in Cairo for ticketing?

If I send a copy of my passport and credit card to the AA CAI office, will they ticket on that or will they make me show up in person to show them the documents in person?

Thanks for the help!
