just want to clear one doubt. I booked Aegean ticket from Saudi to Istanbul via Athens, In Aegean website shows travelers from Extra-Schengen origin to Extra-Schengen destination need to pass through passport control.Will I need airport transit visa for this transfer if I limit myself within the transit area? i am indian and i have heard from my friend who is working in travels that one of his passenger got this experience for stop over visa issue and he paid visa for his family too.

Thanks in advance
