Could anyone give me some advice on when the best time to book flights to Orlando is.
We fly out at the end of July 2013 for two weeks.

I see that British Airways have flights available now but they are very expensive.
Virgin will only let me book up to half way through my second week obviously as you can only book so far in advance but come the weekend my two weeks should be within range.
Would you recommend booking the flights with Virgin as soon as they are available? Should they be cheaper than B/Airways?
Would it be worth waiting for one of the sales Virgin do or do I run the risk of not being able to get my flights as they need to be on particular dates?

Any info and advice much appreciated
Thanks
