Easyjet.
Thanks LAX_LHR.
Can't find any notes for this last winter but as you would expect some frequencies are down from summer. Bilbao and Vienna for example only 2 x weekly for part of the time and Basle 3 x weekly.
Other changes are Geneva which goes from 10 x weekly in November to 16 in January with 4 flights on Saturday.
On CPH, I only found 8 x weekly for some dates in Jan, but 10 weekly in November.
Good to see KEF daily in January and Berlin at 9 x weekly.
The high frequencies are AMS and BFS but not sure how these compare with winter 15/16.
