Same here. I flew LAX-IST-HKG-IST-ZRH-GVA-IST-JFK 2 weeks ago and I am waiting for my miles to post. All in booking class G.
Excellent airline and service, btw. Yes some staff is rude or distant, but the good food, free Wi- fi on transatlantic flights, lounge in IST and the free layover hotel made this an unique experience.
