It looks to me like there is only flights between Istanbul and Adiyaman on Turkish airlines.
Do no other airlines fly in/out of Adiyaman?
THY fly from Ist.Ataturk and their budget carrier Anadolujet fly out of SAW airport on teh European side.
Thanks for the reply! Do you know if there are any flights between Adiyaman and airports other than Istanbul? I'm trying to figure out the best way to fit in a visit to Mount Nemrut. Right now I'm looking at a 3-day tour departing from Goreme but if I could fly in/out of Adiyaman maybe I would skip the long bus ride.
