Lets say you buy a new Chevy Malibu on July 25th.
A week later on August 1st, GM puts an additional $1000 rebate on the car. But you've already bought yours.
Do you think GM is going to give you back $1000?
I agree, it sucks, but that's business. For me, this entire frequent flyer program is a joke. Its nothing but an incentive for me to fly an airline that will give me more than a year to earn miles instead of DH.
