Now that you've signed up for TSA PreCheck membership through the Transportation Security Administration, it's time to take advantage of your benefits.

Since airlines aren't automatically notified that you're a member of the pre-clearance security program, you'll have to make sure your TSA PreCheck membership information is added — and correct — on future travel bookings. Then, you can use the dedicated security lanes at the airport.

Here's how to add PreCheck to a ticket before your next flight, including details on adding your number at four major airlines.

What is TSA PreCheck?

TSA PreCheck is a membership-based program that allows travelers to use expedited screening at airport security. You don't have to remove your shoes, belt and light jackets, plus electronics and 3-1-1 liquids can stay in your carry-on bag during screening at participating airports.

To apply, you'll pay a fee, submit personal information for a background check and attend an in-person interview. The application fee is $78, and membership is good for five years, which breaks down to $15.60 per year; however, many travel credit cards reimburse the application fee. Here's a quick list to reference:

After the initial application fee to join the program, TSA PreCheck renewal — which is every five years to continue membership — costs $70 if completed online.

Each airline has its own process for adding TSA PreCheck to a ticket or to your frequent flyer profile. Adding it to a ticket won't guarantee that your PreCheck number will be automatically applied to your next reservation.

🤓Nerdy Tip

Adding your TSA PreCheck Known Traveler Number, or KTN, to your airline loyalty program profile is your best choice. This will make it easier to include your KTN when booking through your account or when attaching your loyalty number to a reservation.

Wondering how to add TSA PreCheck to Southwest Airlines, Delta Air Lines, American Airlines or United Airlines? We provide step-by-step instructions for new and existing reservations.

How to add TSA PreCheck to Southwest

Southwest flyers can add their PreCheck membership information at several steps.

For new Southwest bookings

Enter your PreCheck KTN during the booking process. After you've chosen your flight dates and times, you'll enter your name in the "Who's Flying?" section. Below that, there is a dropdown menu for "Secure Traveler Information."

Click that button, then enter your PreCheck number in the "Known Traveler #" field. This will make sure that your PreCheck number will be submitted along with your information to TSA's Secure Flight system for processing.

For existing Southwest reservations

Adding TSA PreCheck to an existing Southwest reservation is pretty straightforward.

After you log in to your Southwest account, you can manually edit each flight to add your PreCheck number before check-in or call customer service and ask that they do it for you.

You can also add your PreCheck KTN to your Southwest Rapid Rewards member profile. This allows your information to be automatically sent to TSA when booking reservations when you're logged in to your account.

How to add TSA PreCheck to American Airlines

The easiest way to add PreCheck to a ticket on American Airlines is to update your AAdvantage profile with your KTN.

Log in and go to "Your Account." Choose "Information and Password," then add your PreCheck number in the Known Traveler Number field in the "Secure Traveler" section.

For new AA bookings

American Airlines also allows travelers to add their TSA PreCheck number during the booking process. After you've chosen your flight date and time, you'll enter your passenger details.

If you're not logged in to your AAdvantage account, you'll need to enter your PreCheck number manually in the Known Traveler Number field.

For existing AA reservations

You can also add TSA PreCheck to your existing reservation on American Airlines. To do so, click on "Manage Trip" for each reservation. Then, click on "Add/Edit Passenger Information" to add your PreCheck number.

You can also call American Airlines customer service to have them update your information, but the online self-service option is generally quicker.

How to add TSA PreCheck to Delta

To add PreCheck to Delta, after your PreCheck application has been approved, log in to your Delta SkyMiles account to update your profile. The TSA PreCheck/Known Traveler ID field can be found under "Personal Details."

For new Delta bookings

To add your PreCheck KTN to a new reservation, the best way is to first log in to your Delta SkyMiles account. This will automatically populate most of your personal information necessary to complete your purchase, including adding your PreCheck number to your reservation.

If you don't have a Delta SkyMiles account or aren't logged in, you can add your Known Traveler Number manually during the booking process when entering your passenger information.

For existing Delta reservations

Can you add TSA PreCheck to an existing reservation Delta? Yes, those reservations can also be updated to add your PreCheck number.

Find your reservation on Delta's website, then edit your passenger details to update your information.

How to add TSA PreCheck to United Airlines

Finally, here's how to add TSA PreCheck to a United ticket.

For new United bookings

When booking a reservation, your PreCheck number will automatically populate when you're logged in to your United MileagePlus account. You can also manually add it to a reservation during the booking process.

After entering your personal information, click on the "Known Traveler Number and Redress Number" dropdown menu.

Enter your PreCheck number in the "Known Traveler Number/PASS ID" field.

How to add TSA PreCheck to United after booking

You can also update existing reservations with your TSA PreCheck number. Go to "Edit Traveler Information" in the "Manage Reservations" section on the website, at an airport kiosk or in the United app.

To add your PreCheck number to your United MileagePlus profile, log in and view your personal information. Click on "Profile and Preferences" and find the "Saved Travel Documents and Numbers" section. You'll be able to update your profile with your PreCheck number here.

Adding TSA PreCheck to your flights recapped

Once you're approved for TSA PreCheck, your benefits are not automatically applied to your flight reservations.

However, the answer is yes to the question "Can I add TSA PreCheck to an existing reservation?"

You must update existing flights and your airline loyalty program profiles to be able to use the dedicated airport security lanes for PreCheck members.

Be sure to reprint boarding passes that don't have the "TSA PRE" stamp on them. If your boarding pass doesn't show your PreCheck status, you cannot use the TSA PreCheck security lanes.

For future reservations, log in to your airline account before booking your flight. Booking flights while logged in allows your PreCheck number to be added to reservations automatically. Or, you need to manually enter it yourself.
