I don't think Flybe have released any winter routes generally yet Househunter.
Flybe thread claims the return of EXT-LBA-ABZ, but it may be just flybe updating their site which results in "old" routes appearing again prior to update.
Plus they & other airlines do make announcements "outwith" the usual windows of releasing summer/winter routes.
I guess "keep checking their website" is the maxim...
