Railgun,
Maybe the MAN - JFK route makes £22M profit per annum but it has NOTHING to do with CXP. That profit is part of BA Mainline.
The route is a BA Mainline one, (always has and always will be) and is crewed with BA Mainline Flight Crew.
The only connection with CXP is that presently, the Cabin Crew are ex BAR based at MAN.
There is a distinct possibility as from April next year this will be operated with LHR Eurofleet Cabin Crew, MAN Shuttle Base, or GB Airways according to Galley FM!
