Just a datapoint:

I've had a number of AS personal cards over the past 3 years - 7 in total. My most recent card was about 6 months ago, which I closed about 2 months ago (after lowering credit line). I also have a AS business card that is about 3 months old that is still open, as well as a Merrill+ personal card which is about 6 months old.

I am about 30K miles short of an award I'm planning, so I decided to take my chances and throw in an app for another personal card. Based on the new 2/3/4 rules I do qualify for a new card (I did not break the 2/3/4 rule).

I was approved after being pending for 2 days, but not sure of credit limit yet. Did not call recon this time, but rather just tracked my app status online. I know there are reports of these approvals being rescinded so I will keep my eyes open, but so far so good.
