I used my FF miles to book a flight, I paid the unbelievable surcharge and booking fees which equaled the cost of a flight. An hour later I realized I had booked the wrong date, I called customer service and was told I could get my miles back (whew) but that I would be assessed a $100 flight change fee , even though I canceled the flight and did not rebook, which would have cost $100. So I was under the impression that you had 4 hours to change a flight without any penalty, apparently that has changed. Delta stole my money.
There policy's change on a whim and it is never a benefit to the customer.
