JERSEY ZONE! I dont fink so!
The only thing that makes Jersey Airports small profit into a large one is the humongous amount of cash they weedle out of Eurocontrol each year for providing this service.
If this service was threatened I think you'd find the lads & lasses at Jersey fighting you on the beaches.
This apart, what makes you think that LATCC Atco's are capable of handling such an expensive area of airspace without breaking it or nicking parts of it for their own use.
