Wow, I too am surprised this announcement has come so quickly. Must have been in development for some time and kept pretty well under wraps.
True international style PEY product with 38" pitch, 2-3-2 on the 789 (and in turn presumably the same on the A330s, and 2-4-2 on the 772s and 773s), amenity kits and upgraded dining that looks similar to domestic F.
Considering all the rumors of DL introducing a true international PEY with their recent fare class changes to Comfort+, I'm surprised AA has beaten them to it.
