I've been pricing long-haul bus class tickets from N America to South Asia and Australia, and just realized what many others already know - that the RTW fares can be as inexpensive as (or even several thousand dollars cheaper than) regular fares. I'm drafting a corporate budget for planned travel later this year for these trips, and want to be sure that I'm not underbudgeting by using these RTW fares as references. Could anyone summarize the pros and cons of RTW tickets (including pros and cons in terms of BAEC tier points and miles) for use on business trips (or identify an existing thread I could read)? I'd likely be booking all (or most) of the segments about 4-6 weeks before starting the trip, and might add a few leisure stopovers en route. Thanks.
