Airport security is one of the most annoying part of flying for most travelers, but TSA PreCheck makes the experience quicker and easier with expedited security screening at more than 200 US airports. In TSA PreCheck dedicated lines, you don’t need to remove your shoes, laptops, liquids, belts and light jackets.

If you don’t have TSA PreCheck or Global Entry — which grants TSA PreCheck privileges — sign up for a credit card like the Capital One Venture Rewards Credit Card or Chase Sapphire Reserve that includes Global Entry or TSA PreCheck as a benefit. Then, apply for Global Entry or TSA PreCheck. Once approved, you’ll be given a Known Traveler Number (KTN) that designates you as a Trusted Traveler. Here’s how to find your KTN if you don’t already know it:

Simply having a KTN isn’t enough to get TSA PreCheck though — you’ll need to add your KTN to each of your flight bookings. Here’s how to add your KTN to your frequent flyer account for each airline that currently participates in TSA PreCheck — or, for airlines that don’t make it easy to add this information to a frequent-flyer account, how to get your KTN added to a particular booking.
