What is, is there, a definition of 'round the world'?
I see that Ozzy (thread initiator) has now looked this up. I must say that I am surprised it was set so long ago. This is the starting point of most any kind of record attempt:

I am not aware of any scheduled RTWs, such as the PA 001+2 but many, many carriers and agents now have standard RTW tickets. The problem is that they are not always going to cover the Anti-Podal points and will be designed for the leisure / student pax and aimed to fill thin sectors in their catalogue.
I would have thought that the individual attempt would be more attractive to sponsors than a team. You can bill yourself as a Solo RTW trip! However, you would want to try and get your sponsors to put you in Club!!! Some years ago, I had to go LHR~SFO for a one day meeting and then on round to HKG and the whole thing in Y as the client would not pay C. That was only two thirds of the way around AND I got one night in a hotel and I was zonked big time.
