At least it (for now) will not apply to consolidator fares in the Asia/Pac region, where I believe these types of fares are still pretty prevalent. But I think some people are going to be very surprised when they get tickets through a travel agent, don't realize it is considered a "special" or "unpublished" fare, and get just 25% of the mileage for the trip.
What is scary about this change is the thought that it may eventually creep up to published fares as well.
