Thanks! I was just able to redeem some expiring-this-year points for airline miles, after seeing how many of my points are expiring this year (both things you can't do on the current site). It worked flawlessly for that (in Chrome), even remembering my airline FFP number (as it always had done when the old site was the only site).

However, a slight bug: After redeeming 10k points, the top of every page still shows my old total, but in the My Account drop down it shows the total with the 10k deducted (as it does in the Current Statement pop-up).
