Pending Status
I've found that it takes about 8-10 days for the transactions to show up as "pending" in your account.
I had 4 transactions during the month of March, that seemed to be the timeline.
Now my problem is figuring out when they go from "Pending" to being creditted to my AAdvantage account. I thought it would be at the start of the new month, but there haven't been any changes yet. Since March to April is also a quarterly rollover, I guess that throery is out the window too.
