I'm not sure. In fact I'm a little worried about Bournemouth since it doesn't even have flights from February uploaded yet. They haven't done Nov-Jan from Bournemouth for a couple of years anyway, so am certain that won't happen.
I think what usually happens is they only release Bournemouth schedules only once a year rather than twice at every other base, with flights from February right until October being released around November time. So effectively its winter timetable (Feb & Mar) comes later than other airports, but the summer (Apr-Oct) is earlier. I guess we will just have to wait and see what happens!
