Same here - we never applied for TSA Pre-Check since we only fly usually once or twice a year these days. But somehow, we always seem to end up with it. I thought it might have had something to do with First or Business Class tickets on the customary airline we generally fly but then we started flying on JB a lot and always end up with it there, too. I can’t tell you how disappointed I was when it was suggested to me that it might have something to do with age. Don’t know one way or the other for sure, but whatever the reason, I enjoy the reality.
