Good for you, take advantage of the perks.
But airlines are cutting back on these perks, for example Delta now says you must be on a ticketed flight within 3 hours of the scheduled departure time to get club access.
They then put out a caveat, lifetime can continue to enter anytime without a plane reservation as that was the condition when I bought the membership.
My wife and I have met several famous people at the Delta lounges in Atlanta.
