I am looking to book an award flight with TK - SFO-IST in June 2024 using TK's miles and seems it is only available only up to June 15th currently for booking and there are no saver seats available in June either in Economy or Business.

I actually want to fly SFO-IST-TBS but seems that IST-TBS segment award flights are becoming available only several weeks/months after SFO-IST is available. As a result, either I am risking not to have any seat available in SFO-IST segment when IST-TBS is available, or have to have two separate bookings and have pay for two flights instead of one.

Or could be information I am missing from the picture...

What is TK's recent experience with business saver flights from the US (not just SFO) to IST? Would it be correct to say that compared to pre-covid it is incredibly difficult to find such seats even when booking a year in advance? What was your experience?

Thanks in advance for your guidance.
