How do I use my TSA PreCheck number when going through airport security?

To use your TSA PreCheck number when going through airport security, simply enter it when booking your flight or add it to your frequent flyer profile. When you arrive at the airport, ensure your boarding pass has the TSA PreCheck logo and present it along with your ID at the designated PreCheck lane. This will allow you to enjoy expedited security screening without removing your shoes, liquids, laptops, belts, or light jackets.
