I've never had a problem in the 9+ years I've had my card. My points post regularly within a few days of the close of month statement. You can check your statement online to see how many points it earned you, then check your HHONORS online to see if the right number of points were credited.

To get a rough calculation of what it should be, multiply 3 by your dollars spent. Sometimes it is higher than this, but should never be lower.
