The WorldPerks Visa card may be just a piece of plastic. But to Minneapolis-based U.S. Bank, it's worth tens of millions of dollars, and that big bundle of money is at risk with the proposed Northwest Airlines merger with Delta Air Lines.
With an estimated 800,000 to 1 million WorldPerks cards in circulation, the annual fees alone come to $52 million to $65 million. Add tens of millions of dollars more in interest on outstanding balances and in merchant fees.
Many credit-card and airline experts see the WorldPerks credit card as a long shot to survive the transition to a new Delta, which for years has had American Express and its SkyMiles card as its partner.
Delta may use the merger as an occasion to set U.S. Bank and Amex against each other in a bidding war that could result in higher costs for the winner -- and for frequent fliers, said R.K. Hammer, chief executive of a Los Angeles bank card advisory firm that bears his name.
"Cinch up your seat belts, you're going to get squeezed," he said.
But nothing is likely to happen this year or perhaps even for months after the airlines merge, if they get government approval.
"There's a long way to go until the merger is complete, but we are comfortable that the contracts we have in place with Delta will continue our partnership," said Desiree Fish, an Amex spokesperson.
U.S. Bank also was eager to point out that no decision has been made on the future of the WorldPerks program.
