Hi TracyG - I am from Wiltshire too, near good old Swindledonia. Like everybody else, I am always looking for the best ways to get to Turkey (Dalaman though) and internal Turkish flights too. I have looked at the Freebird website several times but cannot seem to get to a page with routes/timetables or booking options. Have you managed this, or are you aware of Freebird through an agent?
Incidentally, a really cheap way of getting to Turkey is Easyjet to Istanbul then an internal flight - IF you don't mind it taking alot longer.
