I can confirm - no Skyteam into Ankara (yet - government has built a beautiful huge airport in themiddle of nowhere, and will want to fill it, but not risk competition to Turkish airlines).

Only two viable possibilities :
1) fly into Istanbul and then take a short hop on Turkish (make sure the internal flight leaves from Ataturk and not Sabiha Gocken)
2) fly into Munich and then take a Lufthansa flight direct to Ankara

FWIW, Turkish give good mileage on * with their internal flights...
