US Bank has announced the introduction of US Bank FlexPerks Travel Rewards Visa cards.

The bank said that its customers earning miles on Northwest Airlines by using their WorldPerks Visa cards will have the flexibility to earn points toward free flights on over 150 airlines with no blackout dates or award ticket redemption fees with the new US Bank FlexPerks Travel Rewards Visa cards.

US Bank will upgrade current WorldPerks Visa cardholders to new FlexPerks products beginning in May 2009. When the cardholder’s new FlexPerks card arrives it will have the same credit card number, so no application is required and automatic bill payments should continue uninterrupted, added US Bank.

Cliff Cook, chief marketing officer for US Bank’s retail payment solutions, said: US Bank FlexPerks Visa is designed to upgrade our valued WorldPerks Visa customers to what we truly believe will be the most valuable travel rewards card in the marketplace. We had the perfect opportunity to confirm what was most important to our travel-minded customers and designed a new card program that gives travelers even more of what they seek: flexibility and value.
