Looks like A remains as a higher booking class than P. Some sample availability shows: F7 A5 P5 or F7 A7 P0. It is good as AONEx tickets will have more availability than YUP type fares. A is not just for awards/upgrades. There are some international point-to-pont A fares around.
I wonder if this is a prelude to exclude YUP fares from receiving first class EQM and points?
