I actually would welcome a move to switch from a miles based ff model to a revenue based model.
It would mean that far less people would qualify and more FF (mostly businessmen) would be sitting in coach and would demand a better class of service which would benefit everyone.
With fewer FF qualifying for stuatus the airlines could add perks and it would ensure that status actually meant something and those that really do pay allot get the benefits they are paying for (biz class lounges are so full of people who have used miles to upgrade from cheap tics that they are barely better than airport gates).
Just an idea. Now let me get out of your way so that you can go to work with the flame thrower
