[QUOTE=Capt. Phoenix;166012]A lot of airports randomly let people go through pre check who don’t have it. It’s a thing they have in place for when they get busy. I guess they figure it being random will keep terrorists from getting through.[/QUOTE]
TSA pre-check and TWIC are two separate programs to take money. If you have Pre-Check you have a “known traveler identification number” and you enter that when you buy your ticket. You can get pre-check and TWIC in the same office but they won’t issue you a KTIN unless you pay a fee, get finger printed again and get the EXACT same background check they give for the TWIC .
TSA was allowing airlines to issue pre-check tickets to frequent flyers but supposedly this will not be allowed in the near future, so you’ll have to pay or get in line.
You can get the info on the TSA website.
