American offers its co-brand credit card holders a discount of up to 3750 miles each way (7500 miles roundtrip) on domestic award tickets for a rotating series of destinations. (US Airways used to offer a discount on all awards taken on their own flights for their co-brand credit card holders.)
With the introduction of new 7500 mile one-way redemptions for flights up to 500 miles, a 3,750 mile award (7500 – 3750) for co-brand cardholders seemed like it would be too good a deal to be true. And it was — while the new short haul awards went into effect March 22, the airline suspended discounts on short haul awards through March 31.
