What is Loyality? When applied to a service we buy, it surely is different that to people or pets.
Loyality is a means to an end at airlines. You purchase a bunch from them, and they give you something back you find of enough value to continue with them.
When you don't feel you are still benefiting enough, you move your "loyality" elsewhere.
When the airline does not believe they are getting enough out of you, they change the benefits "you" get.
So this business of loyality with airlines and ff's is a bunch of cr*p. Both are just "using each other". Don't you just love it!!!!!!!!!!!
There are some rare cases where loyality and airlines do exist. Like trying to keep an airline alive and/or serving a limited market imporatant to us (hometown?). This too is motivated by self interest, so I guess it is not loyality either.
