When booking an ONEx there doesn't need to be any discussion up front about ticketing, and nothing special has to be done to have Cairo issue the ticket. Give your itinerary to your friendly neighborhood BA rtw desk (!!!) and let them book the seats. Ask the agent for the record locator. Fax Mrs. Sobhi your details and a couple more faxes back and forth with her and you're done.

You will get points from Mrs. Sobhi if you fax her your itinerary also, with each leg clearly identified with respect to segment number (limit 20), per-continent count (limits 4-6 plus any extras you're buying), and stopover counts for Europe (max 2). You needed to have counted all that stuff up yourself, print out the table so she doesn't have to do the work over. Saves her ten minutes, I suppose, and earns you a friend in a good place to have one.

Just confirmed for my upcoming AONE3 that the Airport Ticket Office is now open 05:00-13:00 with the BA flight at 07:35.

Thank christep. Also, I have a fax here from Mrs Sobhi which says that the ATO is open daily, and the town office open from 0800 to 1600 every day except Friday (in case anyone was wondering - I think it's been mentioned elsewhere before)
