I looked through this thread (not exhaustively) for the N. America RTW "desk" contact nos, and couldn't find them. Sorry if this is repeated info -
BA (800) 828-7797
AA (800) 247-3247
In general AA is far more on top of things than BA.
If you want to save money by originating in another country, the recommended approach (YMMV and how) is to formulate an itinerary, post it here to have it koshered, then phone it into one of the above RTW desks so that it can be given a locator/PNR.
Then communicate directly with a travel agent or airline office in the issuing/originating country in order for them to bring the PNR up and send it off to the tariff people to do that thing they do. AA gets it; however if you try to book a foreign-originating RTW with BA in N. America they will try to price it for N. America issuance, and when you tell them no, it's for (Gibraltar, Mauritius, etc.) you will hear gears clashing and smell smoke.
