I think that Richard Billins policy, if he has one, seems to be "stay small, work at capacity" - to be fair, he does seem to have outlived numerous other flying schools at EGTC by following that model.
Despite that however, when I switched to Billins from Bonus to finish a rating off a couple of years ago, the instructor availabability was far better after the switch.
Realistically, I'm sure that this won't have done Billins any harm at-all, but the real move of work will have gone to CFS. I imagine that in the short term the receivers of Bonus would be glad to rent them some aeroplanes!
