FJE will still be in the fractional programme - but without their own aircraft. Consequently they will be using "partners" with Bombardier products and the operation should be controlled from their London office.
Netjets will not have a monopoly but they should get a sound share providing they don't hike their prices.
I suspect that FJE will begin to lose their client base - some fractional providers do appear to be somewhat expensive! If they do lose their client base then maybe the charter operators will find a need for a few more aircraft and crews - that might give some of the FJE pilots a lookin in a depressed market - I hope so.
