I can't believe that, I'm sure there are many other frequent travelers under 21 that are usually without their parents...they must be losing business, not only from club memberships but from attracting young frequent fliers. I frequent US Airways clubs and they serve alcohol as well, when I travel first class there is also alcohol so that really isn't a justifiable reason, unless there are vodka fountains that members have free access to alcohol shouldn't cause a ban for people under 21.
