I almost don't want to call attention to this, but has anyone else noticed being able to upgrade 1-2 before the window should open? I ran into this earlier this week where I was able to upgrade an S Flex fare to PE 16 days out from flying. Tonight I was just able to upgrade from a Comfort K fare to J 15.5 days out. In both cases when confirming the upgrade AC.com threw an error but I got the upgrade confirmed email and was able to go into the seat selection tool and pick a seat.
Most interesting was the ability to instantly clear into PE which I don't think I've ever done before.
