I'm also looking at buying VS tickets this winter. We want to go to either Barbados, Antigua or The Bahamas. It's strange that with some travel websites you can book say 10 nights in Barbados for around £600 inc VS flights and a good hotel. But then you go to the Virgin website and a rtn flight to BGI from LGW will cost around £500 just for the flight! For some reason BA fares to Nassau and Barbados are much, much higher than VS for the same time.
