New wrinkle -- I've had a pitch for the HSBC Cash or Fly Rewards Mastercard. It's outwardly attractive because you can earn points which turn into cash credits toward any airline ticket, or just take a cash rebate, and it seems much more flexible (ironically) than the new FlexPerks program from US Bank. But I can't tell if the points expire. There's some ominous fine print in the offer: "There is no annual limit on the amount of points that can be accumulated or redeemed in an Account Year (12-month period)." Think that means the points evaporate at the 12-month mark?
