There is 1 excellent freeware LGTS scenery out there: GAP Thessaloniki Makedonia Int’l (LGTS) (FS9/freeware). More info here

This freeware FS9 scenery also works in FSX, but with some minor bugs.
Note: to avoid aircraft misplacement, all pilots are urged to use the same LGTS scenery provided above.
