I try to be "above board" with all of the loyalty programs that do a fairly good job in resolving missing points/miles when I bring that to their attention. Surprisingly, I have found that the vast majority of programs are helpful and post (some quicker than others) missing items.

On one occasion a few years ago, a major loyalty program overcredited my FF account by close to 15,000 miles. This was after 7-8 months of back and forth with one of the program leads as I attempted to receive the proper credits for a bonus promotion. When I called the overcredit to their attention, I was permitted to keep the extra miles because "of all the issues I had with getting the correct mileage posted".

GoldPoints is the one program that I would never notify of an overcredit, although I very much doubt that they ever overcredit anyone. The lies they told, and the pain and agony they inflicted in attempting to receive miles from the ValueMags promotion a number of years ago, has forever put a stain on this program. Their utter contempt for the customer is something I, and many other FlyerTalkers, will never forget. I owe them nothing and that is exactly what they will get from me.
