AB is part of one world and since you were connecting, presumably same day and not overnight can be joined.
No, I don't want access to my bags overnight. I have a small carryon that I can use at the hotel that night. Also, AB is not oneworld yet. That is scheduled to happen on March 20. The date had not even been announced when my friend did her AA/AB trip last fall.
