If you knew anything about the markets you'd know that the Winter season is one of the most competitive and difficult for regional airports to service.
Be they skiing or winter in the sun flights, they make very little money for anyone and operators will only take them on from the larger airports where they know that most flights will be full.
There's no point in any business taking on loss making services, most regional airports will cut down to core operations in the Winter and stick to what they can make money from.
