No offense, but i think you should be greatful for getting a year round based charter aircraft(regardless of what type), especially at CWL's expense, lets not forget EXT is still a very small fish in a very big pond, FCA must have a lot of faith in EXT especially when they could quite of easily put a 3rd base unit in BRS instead to compliment the 2x757s and weekend visiting 767. I think EXT have done really well to get this contract.
I'm sure that you will still get your usual visitors AEA etc... as FC hols will probably want most of the allocaton themselves, especially with the concentration of FC shops(ex Bakers Dolphin) in the area.
