hey IP, what in the hell are you tawking about? I traveled on a NWA booked and ticketed RTW ticket (on NWA ticket stock) for most of last year.
When calling Reservations, merely whisper the words "round the world" and they magically transfer you to a special desk that handles only round the world tickets.
As for business class RTW tickets, they book you in F class when flying domestically. At least that's what NWA did for me. C for business, F for domestic.
Is this a revenue RTW ticket or an award RTW ticket you're talking about, beorbe?
