Q. I was shocked to learn that just changing the date on my frequent flyer ticket (booked several months ago) is going to cost me $150.  As far as I could make out from the fine print on my ticket print-out, there should be no charge, but the agent said the change applies retroactively. How can they do that? Do I have any rights here?

A. Unfortunately, all frequent flyer program rules state that they can change the rules at any time.  With all the new (and rising!) fees required to cash in/change miles, we are advising people to look into cash back cards rather than using frequent flyer program-affiliated credit cards. Frequent flyer programs just aren't what they used to be. Visit our Frequent Flyer fee chart and see for yourself.
