Hopefully ThomsonFly or Monarch will jump in as the winter routes to the Caribbean should be popular. Certainly a few years back Britannia operated to St Lucia, Barbados & Antigua and flights were always pretty much full. I know there's a credit crunch going on, but surely if you holiday in the Caribbean a credit crunch won't affect you (I did say "surely" before anyone jumps down my neck).
Thomsonfly certainly have a couple of 762's that were destined for Silverjet that they could utilse?
