Wow! This one is still available?
I booked mine on October 4th on Orbitz for $366.59.
Actually, I booked this...
17-12-2012 TK0673 IST-JRO 1935-0320
30-12-2012 TK0673 MBA-IST 0625-1210
I nested this inside my ORD-AMS-IST-AMS-MSP-ORD on Delta for $536.30.
So, in effect I got myself a open jaw African Christmas mileage run/trip for $902.89.
Great fare if you're in Istanbul.
