I was affectionately refering to BA CityFlyer which was a well run profit making outfit until we got to grips with it.
You mean CityFlyer Express, FD rather than CX.
I think the best example I ever heard was the CWL-GLA route that was flown by the Jetstream 41. This had been a good route for Manx ( Europe ) and later British Regional Airlines. The day and hour that BA took them over, the different internal accounting structures flagged the route as a heavy loss maker and it was binned, so begininng the dismantling that ended with the sale to flybe a few years later.
I think this is the reason they need to keep BA CitiFlyer at arms length, as the moment they bring RJ100s flying from LCY in house, it will show major losses, more so than now if that's the case.
Such is the sheer complexity of running a large business! I'm not criticising, I just wish we were all better at it, myself included. This is also the reason that many feel patience is at an end with continued bleeding cash at Gatwick.
