All Flybe flights are staying apart from the LGW, to be operated by non based A/C. (the LGW has been picked up by EZY)
Of The HIAL airports INV and LSI break even i believe. The rest lose large amounts of money. The subsidy is payed to HIAL not the airport. Of the lose making airports apart from Dundee could easily be argued as requiring a subside as their is no way the island airports could operate with out it and they are required. I doubt the island airports are the type this is aimed at and their will be some loop hole to allow it to continue.
(sorry for the disjointed reply had a few drams)
