There are some mainline pilots based at MAN and BHX on the 146-RJ100 (possibly EDI soon too!) However, in the short term at least, there will be no future vacancies.
The MAN JFK is a profitable, BACX (wholly owned subsidiary) route, which is crewed in the front from LHR (and is apparently quite a senior trip!)
Of course, there are also a handful of BA pilots at Stansted too!
