Easyjet have scaled back schedules consistently in recent Winter's. It obviously brings capacity in line with demand whilst still maintaining the route. Again as in previous years increased frequencies maybe added where demand is sufficient.
I can say for sure however that GVA will see frequency increases this Winter with an additional service on a Friday, and a third frequency on a Saturday and all buy one of the GVA's each week will now be MAN operated.
SSH will become a 3Xweekly service which is (I think) what it was last Winter.
As usual though, the majority of the frequency "scale backs" are the AGP's and ALC's. Theres plenty of competition and mid-week Winter can be incredibly slack as these destinations are near as damn it Weekend style destinations during that time of the year.
