BRS is FCA's biggest regional base behind MAN and LGW it handles more than BHX, GLA, EMA, STN, BFS, DUB, LTN and of course CWL, but it does remain a mystery not just to outsiders but crew and other company workers as to why FCA think that they cannot get the business to base CWL all year.
as well as operate the EXT winter prog, in my humble opinion there is more than enough business to operate year round BRS/EXT/CWL programmes alongside each other, theres probley enough to increase in BRS during winter aswell, XLA and KM will be picking up that business now though
