That's my thought, too. Before last October, I had several accounts opened for myself and had never had any problem - the miles posted automatically and "somewhat" timely. Then I opened an account for a friend in late October 2010. The 2,500 miles posted pretty quickly, but by early Jan the 22,500 miles had not yet shown up. I sent Chase a secured message. The miles appeared in my friend's OnePass account within 3-4 days, even before Chase responded to the initial secured message. So I guess it was just a one-off mistake.
