i flew 32 individual flights last year, and to be honest its really just the same thing as getting on a train. it helps to fly the same airline if possible, so you know their routine and policies and it makes everything a lot easier.

precheck really only saves you time if you frequently fly, frequent airports with notoriously slow security (im looking at you Denver), and you consistently run late. i didnt have precheck last year and it only hurt me once (again, looking at you Denver).
if youre a weirdo that has a problem with taking your shoes off in public, or if youre one of those people that struggle with common sense and wear kneehigh lace up boots when going through airport security, then i suppose precheck would also help you.

bs only occurs when people (fellow travelers) dont know how to be humans. this applies to all forms of travel, not just planes.
