We traveled to SXM the later part of June and when we got to the airport and printed our boarding passes they had TSA Precheck printed on them. It was nice having a shorter line at the security places, but I am wondering why we had this on our passes. We never applied for it since we only fly a couple of times a year but it showed up. I looked at the precheck site and it says you have to apply for it. Not complaining, but does anyone know why this happened without us applying for it?
