Everything I'm hearing is that BHD will be the first base with operations of any scale, and there will be very little flying at BHX. They sound to be pretty much stuck with having to operate the Heathrow remedy slots or else they are lost. I don't know whether you could or should put those two things together, but even if BHD-LHR isn't on the cards then it'll be interesting to see how they fly the LHR slots without losing their shirts doing it.
