Traveling can be a stressful experience, especially when dealing with long security lines at the airport. With this in mind, many travelers are opting for TSA PreCheck, a trusted traveler program that allows for expedited security screening. If you’re a frequent Southwest Airlines flyer, you’ll be pleased to know that adding TSA PreCheck to your travel arrangements is easy. Here are six simple ways to add TSA PreCheck to your Southwest flights.

1. Update Your Rapid Rewards Profile

Ensure that your known traveler number (KTN) is added to your Southwest Rapid Rewards profile. To do so, log in to your account and find the ‘My Account’ section. Under ‘Travelers Information,’ enter your KTN into the designated field and save the changes. This will automatically apply TSA PreCheck eligibility to all of your future Southwest reservations.

2. Add the KTN During Booking

If you haven’t added your KTN to your Rapid Rewards profile or you’re booking a flight for someone else, simply enter the KTN during the booking process. Locate the ‘Secure Flight Passenger Data’ section and input the KTN in the appropriate field.

3. Modify an Existing Reservation

If you’ve already made a reservation but didn’t provide your KTN at booking, don’t worry – you can still modify the booking. Log in to your account, locate and click on ‘My Trips,’ find the specific flight, and select ‘View/Edit.’ From here, enter your KTN in the ‘Secure Flight Passenger Data’ section.

4. Contact Southwest Customer Service

If you’re having issues adding or updating your KTN online, contact Southwest’s customer service either by phone or online chat. Provide them with your reservation details and KTN, and they will assist you with adding it to your flight.

5. Add Your KTN During Check-In

If you haven’t added your KTN by the time you’re ready to check in, you have one final opportunity during this process. Before proceeding with the check-in, find the ‘Add TSA PreCheck’ field and input your KTN.

6. Utilize a Travel Agent

Finally, if you’re booking your Southwest flight through a travel agent or third-party platform, ensure that they have your KTN on file. Provide them with this information at the time of booking so they can add it to your reservation.

By following these six steps, adding TSA PreCheck to your Southwest flights is quick and easy. Enjoy shorter security lines and less hassle at the airport!
