Depends if BA have one or not.

Seriously, thet will almost certainly have a sale, the question is whether the MCO routes will be included in it, and how much they will be discounted by.
Traditionally, sales often omit MCO but it will all depend on ticket sales, projected loads and lots of other factors. The
current sale, wich ends 8th Aug, os a good example of one that doesn't include MCO, though it does feature MIA right through to march next year.
The trick is to keep checking and, once you see a fare you like, book it. 8D
