Virgin to launch new caribbean routes

Virgin atlantic has recently announced plans to launch a direct weekly service between london gatwick and tobago continuing to grenada from may 2003. Virgin is also planning to launch a weekly sunday service from manchester to barbados st lucia and antigua.

my only question is that Br. Airways already do the gatwick-tobago-grenada route and JMC also does it. Do virgin expect there to be enough of a market to have a 3rd airline included and it will probably be done with a a340-600. have they gone mad, i dont think this will work.
