You never know!
There is no other airport in the SW that can take the A332 to DXB. They have flights to all areas of the UK except NI (not much chance) and SW which is quite a large district and as we have seen on the BRS thread, there are alot of people using connections on the continent to the middle/far East instead of travelling to Heathrow.
Never say never, but I cannot see it until at least late 2009.
