AA takes at least 3 days for miles to post after a trips completion. DL posts immediately. Do any "insiders" know if aa plans to revamp its posting system?
(On the london subway, if you use an oyster card, you can see your trips post in real timeimmediately.)
It really depends on when you fly as to how long it takes for the miles to post. I really don't see what the big deal is though.
