Two years ago BLK DUB was flown with bandits. Now its a shiny 737-800. A similar story could happen on IOM LPL and IOM LTN. How long is the BHD GLA sector - which was operated by ATP's and now 733's!
Never doubt the ability of low cost carriers to at least double traffic on routes.
Oh, and if an A319 can land at LCY, it can land at IOM.
