How can I use PreCheck to expedite my airport security screening process?

To expedite your airport security screening process using PreCheck, you can apply for the program online, schedule an appointment for an in-person interview, and once approved, provide your Known Traveler Number when booking flights. This will allow you to use designated PreCheck lanes at security checkpoints, where you can keep your shoes, belts, and light jackets on, and leave laptops and liquids in your carry-on bag.
