BA is a smart marketing org. The exec club is about building relationships with premium passengers (i.e. First, CLub and full fare/premium economy who travel regularly) and they will have a view about the likely leisure pursuits of the target audiences. They obviously don't feel that aviation links to premium passengers strongly enough to justify segmenting that audience.
I'm not passing a personal opinion, but I have worked with the "world's favourite" (as an external consultant) and have a higher regard for many of their people than some others on PPrune!
