@Guy Betsy : do enlighten me, what's the politically correct, and short, term for "clearly stated benefit in a loyalty program, which you have qualified for in every way as far as is humanly possible, and made clear, reasonable, polite, efforts to clarify" if it is not "entitled."
I am not sure why the ad hominem attack in the rest of your post. I disagreed with a post by someone, pointing out data from other passengers. I did not say he was impolite, or rude, or whatever, which you pretty much did about me.
If I was flying AA, I would go the AA lounge, which is the lounge I would be <insert your word instead of entitled> to- no?
fwiw I have been given bottles of champagne as I left the plane as a "nice passenger" gimme.
