He can by now I believe but flying with them is quite difficult or at least not as easy as flying with his dragon wings. It never exactly said he could fly with his devil wings but he was able to teleport through a magic circle after his training with Tannin. But at that point I don't believe he could fly with his devil wings. Now it most likely is different but very difficult or not as easy as flying using his dragon wings.
