I would agree with hsi. on this one. I think there is room for a RTW message area. From my own point of view I think that unless you are traveling business/first class you are better off not buying a comprehensive RTW ticket. This allows the utmost in flexibility and usually ends up cheaper. I have done this before and buy my tickets as I go. $169 from JFK-MAD. $350 from MAD-HEL-BKK. $1050 BKK-NRT-JFK (business class on ANA). All but the JFK to MAD segment were credited on my Delta Skymiles account.

I think it would be interesting to discuss what cities are better for buying tickets, and what routes have particularly cheap fares, etc. I think that RTW discussion within alliance message boards tends to constrain the discussion. An RTW message board would let people freely explore other options, not just those aligned with a particular airline alliance.
