Richard,
What routes are you referring to regarding Newcastle, as far as I'm aware Fly-Be did Newcastle a great service by moving in there and within a day of Gill going bust, taking over the NCL-CDG and NCL-BHD routes and honouring all previous tickets sold.
Don't underestimate Fly-Be, I would not be surprised at all that they are looking at capitalising on the demise of Buzz at Bournemouth.
When it comes to it they can react VERY QUICKLY.
