Buried in this article about the "semi"-upgrades to the AA 767-300s, Nocella says the US 767-200s will be flying through the summer of 2015. Originally, they were supposed to be gone last year. Then, the plan changed to "gone in 2014."

"Actually, the old US Airways 767-200s will be the first to go. They actually anticipate keeping them flying through the summer of 2015 for one reason – it allows them to accelerate the work being done upgrading the 767-300s. But after summer 2015, those airplanes will finally become beer cans."
