I had called that listed AA contact number yesterday, and struck a very unhelpful woman who said that RTW tickets could not be purchased over the phone and I'd have to come to the Paris CDG ticket counter in person.

Today's call was completely different - polite, helpful and after some 10 minutes or so, e-ticket issued off credit card details supplied over the phone.

For now it's a simple LONE3, NCE-LHR-NRT-DFW-TPA-MIA-CDG, with the LHR-NRT in T on BA. But I plan to reissue to get some North American flights and also some extra European sectors. At €2475 all in, it's pretty good value.
