We recently learned, after the fact that we lost our frequent flyer miles. American Airlines took away 26,346 earned AAdvantage miles. We received no notice of a change in their program, so we had no idea that a new policy would be in effect that could result in the loss of our earned miles. We earned these miles prior to the changed programs effective date of December 15, 2006 and had no idea that they would not be grandfathered and thus not be affected by this changed program. We did not understand what was meant by ”inactivity” unit we spoke with a representative of American Airlines. We find that neither of two options of “re-engagement” can possibly help us to redeem these miles.
