and underwent security checks on three separate occasions when I boarded. I don't believe that I have ever completed separate paperwork or paid any sum for TSA PreCheck, but that status was clearly indicated on my tickets and I sailed through all checkpoints without a problem. It was the most painless security experience I have had in the US.
When I mentioned my experience to my husband (who hadn't been with me), he said that he thought that people my age were automatically eligible for TSA PreCheck. But I reminded him that when we flew together a couple years back, I had the PreCheck and he didn't - and he is even older than I. 
Per this link, I see no automatic eligibility. http://qz.com/478039/the-complete-guide-to-getting-global-entry-and-tsa-precheck/
While I am very happy to have this status, I still don't know how it happened.
