Doubt they would integrate Citiexpress. BA promised pilots that buying BRAL would not make the combined Bral and Brymon a training base, nor train pilots on props/regional jets, and if chopping all European routes off to them they would be recinding on this promise. If it was integrated, then it would mean TEPs would go off to regions on props: going against what they said. In addition they promised not to integrate it all anyway.
Mind you: do you trust corporate promises?
