re: TSA Precheck

That's not necessarily true. If you don't have Precheck then you might luck out and get it if traveling with someone who does. There have been plenty of times I have seen it work out the other way where one person gets it and the other has to wait in the regular line.

If you fly one time per year, it works out to like 17/year. Worth it in my opinion. We signed my daughter up for it as well as soon as she hit 14. That's the cutoff age for getting it automatically if you are traveling with someone who has a KTN.
