TSA PreCheck is a program for travelers run by the US Government. Once approved, you get a special “TSA PreCheck” indicator on your boarding pass, which lets you use dedicated PreCheck lanes at security checkpoints in over 200 US airports, and right there, a CLEAR program is operated by a Private Company. Moreover, when it comes to who is better between the TSA PreCheck vs CLEAR, PreCheck suits most travelers better, while CLEAR benefits frequent flyers.
