hi all - i am looking to get on a nonstop TK flight from IST to almost any US destination on a specific date in September 2025. Does TK release biz availability periodically throughout the year? There is somewhat limited availability from August-Sept next year, but availability picks up from Sept 16 onwards. Mostly curious TK historically only releases seats 355 days out, or if they release seats randomly throughout the year. I am checking daily, and use seats.aero.
