LDY has been on the BA booking engine for an age now, since Loganair did LDY DUB on PSO.
I've just has a mad thought, is Jet2 a crazy idea in relation to operating the STN LDY route now that they are based at the Essex Airport? Outside of that it can only be Flybe (Stobart) or Loganair. EasyJet can serve a small island community like IOM from LTN and LGW, would they did their toe in the airport with a route to STN, might be attractive without FR on the route...
