When I flew last year, I chose a business elite itinerary LAX-JFK-IST on Delta and then added on business class on Turkish Airways for the short-haul domestic connections between IST and Ankara. You may also be able to fly directly to Ankara ex Europe via CDG or AMS on Sky Team. If you take the Turkish airlines connection option via IST, which I like, remember that the airline in Ankara has a separate business class terminal for check-in. Thus, the taxis will try to take you to the main big terminal while it's far better in reality to go to the Turkish Air exclusive business class check-in terminal. Also I liked to pick up some carpets on the trip-- with this connection, I was able to use the 3 suitcase 70lb allowance in DL business elite for the return flight and only needed to pay $60 excess luggage for the third suitcase ex Ankara because it was for the short-haul domestic flight. KL/AF would have slammed me with the international excess baggage fee of 150 EUR if I had flown Ankara to Europe.
