Actually, that's not correct. Over the years I've posted several deals for flights to Turkey from Edinburgh - the problem is that folks want the £149rtn's in July and August of yesteryear, that simply doesn't happen any more during peak periods.

First flights of 2018 season from Edinburgh with bags, seat allocation and meals £ 765.80.
Last flights of 2018 season from Edinburgh with bags, seat allocation and meals £ 894.40
6th of June for a week with THY via Istanbul £207.54.
Includes 23kg, meals, seats etc.
That's a random week, there'll be cheaper, and probably more expensive.
No cheap deals from Edinburgh?
