The fact remains that when people spend money and accrue miles in year x in reasonable expectation of certain benefits in year x+1, because those are the benefits that exist at the time, the airline ought not to be allowed to change those benefits until year x+2.</font>
A conclusion would be that every year an airline would have to maintain the same amount of reward ticket percentages in each category.
If for example, AA gave 8% of reward seats in 2001, then in 2002 the reward seats percentage should be the same. Extrapolate from 2002 to 2003, and so on.
