VS (or anyone else) to SJU?
According to Wikipedia list of airlines serving SJU:
Virgin Atlantic Airways (starting May 20, 2004)
Nothing about this anywhere else, so I would presume their info is false.
I think BA have been there before. Is there a gap in the market here? A large Caribbean island (certainly the largest without direct flights from the UK), a very well established tourist industry, interesting mix of Hispanic & American culture + some stunning natural scenery. Presumably there is capacity - about the only airport in the Caribbean with 2 parallel runways (?) + various extension work going on the terminal buildings.
I would have thought BA would make more sense than VS, due to the potential to tap into the huge range of American Eagle connections from there.
