I'm wondering if anyone else has trouble using their Platinum Elite card (or any Elite card) in the check-in machines at airports. I've taken to using a credit card to check in b/c my card hasn't worked since I received it last year.
I'm just requalifying as Plat for 2011 and am hoping I get a card that works when swiped. I've asked for a replacement but never received it.

I've tried using my President's Club card and THAT doesn't work either. Is this something new or am I just unlucky?
