For chase CO card holders but might work for anyone with a CO account.https://www.continental.com/web/en-US/apps/onepass/promotions/registrationDetails.aspx?promoCode=TB3M37
From what Ive heard it won't work for non Case CO holders.I also received both of these in my accounts over the weekend:07/01/2011 Continental/Chase Rec Payments-100 Miles 10005/01/2011 Hotel & Car Redemption Benefit/Bonus 100
It seems I've been receiving these for some time now, even though my CO OPP card has been cancelled for some time now.
Either way, its worth the 5 seconds to register.
