They are also aware that the other major airlines are following suit. So, the lesson here is to stop thinking that this is a two-way street and that loyalty begets loyalty. You should look at every decision from the perspective of what is best for you - under the rules in place today. Do not assume that any loyalty will be returned. AA and UA will be no different overall - but if there is a specific policy that helps you on one airlines more than on another do what is best for you. This is like a referee's instruction in boxing - protect yourself at all times.
