bmibaby would certainly have more luck running a low-cost schedule from Manston than there attempts at establishing some kind of low-cost flying from the south-east out of Gatwick. With bmibaby's love of changing airport names, not sure what Manston would end up as though?
I'm very sorry to hear that EUJet has folded operations. I've had the pleasure of flying from Manston, and everyone I came across were both extremely friendly & professional. Best of luck with whichever company you move onto.
