Seems to be a bit of room at one end of the runway at Dundee. Have a wee look at this
Dundee Airport
Being of Dundonian descent, I'd love to see Dundee get a big boost with a successful low cost airline. It should attract from all over Tayside and Fife and possibly even as far north as Aberdeen and as far south as Edinburgh - Prestwick isn't too easy to get to from Edinburgh. The rail track to Glasgow does indeed go right past the front of the airport and this should be taken advantage of. The combined population of Tayside, Fife and Central Scotland is quite considerable.
