I've had 3F seats before now. I also remember whilst in AUH at new year almost every cabin went to 3 available on nearly every route to Europe for the year, that soon changed though and I've not seen it again. I general 2 seats are released (in my experience) and no more.
The route I got 3 on was IST, I may as we'll share that because I WON'T be going back.
