No, the 767-300ERs do not feature PTVs in economy. Also, I believe that the 767-400ER flight currently on ATL-FCO is a domestic aircraft sold as all coach, and it only has PTVs on the domestic first seats, which are reserved for Elites and Y/B fare passengers.

Eventually all 767-400ERs will get PTVs in economy and BusinessElite seats. Five more will be converted for 2008, and the eight remaining aircraft will be converted for 2009.
