The odds are pretty zero if you are planning to depart from Istanbul and go to the USA as a non-stop passenger. Slightly more probability, if you are connecting via Istanbul and originating from another country.

Istanbul - USA flights tend to be full from May to September with a very high demand for Business Class of passengers paying cash fares, thus it's highly normal for them not to open award and upgrade space until closer to departure ( 2-3 days ) and only if the flight is wide empty. This was the case for years for summer peak season as they don't want people to rely on mileage upgrades/awards during high season to incentivize someone who wants to fly J to pay J.
