I’ve had a look at the FR winter timetable and it looks as though the following flights will operate using BRS-based aircraft.
Bergerac: Mon, Thur
Beziers: Mon, Fri
Bratislava: Thur, Sun
Budapest: Mon, Wed, Fri
Derry: Mon, Wed, Fri, Sun
Dinard: Tue, Thur, Sat
Dublin: Daily (see below)
Gdansk: Wed, Sun
Katowice: Wed, Fri, Sun
Knock: Mon, Wed, Fri, Sun
Marrakesh: Tue, Sat
Milan (Bergamo): Daily
Poznan: Tue, Thur, Sat
Riga: Mon, Fri
Rsezsow: Wed, Sun
Szczecin: Tue, Sat
Turin: Sat
Wroclaw: Tue, Thur, Sat
Interesting that Bergerac and Beziers remain for the winter but not Pau. Porto also seems to have been dropped.
Compared with last winter Derry is down from daily to 4 x weekly (but the same as for the current summer), and Bratislava, Budapest and Riga have all lost one weekly rotation.
However, one of the daily Dublin flights seems to be operated by a BRS-based aircraft (out from BRS at 1600 each day and back at 1825). In total the DUB route sees 25 weekly rotations.
Finally the Shannon (6 x weekly) and the Girona (4 x weekly) still appear to continue to be operated by aircraft from those bases.
The upshot is that at least part of each day will require 3 based aircraft as the timetable currently stands.
Can't help with the CWL rumour other than having read it on a number of message boards.
