I dont think BE will have that large a number. Despite frequency, they only operate Dash-8's and E195's, against the B757's and A320 family of the charters.
Id imagine easyjet have a large number with their 5 based units, 4 of them being A320's and even a based away A319 for the Genevas.
Talking of easyjet, there seems to be speculation that the DSA frame will be shifted to MAN in January, as all winter routes for DSA end in December, but all other winter timetables go right through to Feb. Mix this with talk that a 6th based frame will be added to the fleet, and AMS is being added to MAN's schedules (a DSA route), it seems to add up.
