Lots of Scots (often ex-BAe PIK people but originating from all over the land of Burns) work in TLS, mostly for Airbus, with lots of Visiting Friends and Relation - VFR - traffic. Not to mention the potential vacation traffic - ski-ing in the winter and the lovely Toulousain countryside in the summer.
How about EDI or GLA or even PIK to TLS? The FlyBe TLS-BRS service seems to work well so why not TLS to one of the three main Scottish airports? Thrice weekly would be a good start. What about it FlyBe or EZY?
