Sorry to bump an old thread but I am looking for confirmation of something...
I am trying to book AA using AS miles on SLC-PHX-PVR and I see different availability on AA.com vs AS.com. I know that AA uses married segment control for awards. Does AS pull AA availability as an O&D or do they piece it together by segment? It appears to be the latter but I am looking for confirmation. If it is by segment, why does AA allow that?
