Unable to Book Front Row Seats on Turkish Airlines

Being a tall person, it's a constant challenge for me to find seats that are comfortable. That's why I always opt for front row seats, as they provide the extra legroom I need. Unfortunately, Turkish Airlines consistently denies me the opportunity to reserve these seats, even when I search for flights well in advance, such as on July 30th, 2025. The front rows are always indicated as fully occupied. I'm having trouble comprehending how this is even feasible.

After carefully examining the seat selection policies, it is evident that there is a lack of clear information regarding the reasons behind this occurrence. I kindly ask for prompt attention and resolution of this matter, so that passengers such as myself can easily reserve seats that meet our requirements.
