Traveling through airports in the U.S. can often be stressful and time-consuming, especially when it comes to long security lines. Fortunately, the TSA PreCheck program offers a smoother, faster security screening process for low-risk travelers. If you’re flying with American Airlines and you’ve already been approved for TSA PreCheck, adding it to your booking can save you time and hassle. This article provides a comprehensive guide on how to add TSA PreCheck to your American Airlines booking—whether you’ve already booked your ticket or are about to.

What is TSA PreCheck?

TSA PreCheck is a U.S. government program that allows pre-approved travelers to move through airport security more quickly. Enrolled passengers don’t need to remove their shoes, laptops, liquids, belts, or light jackets during screening. Most travelers report significantly shorter wait times in dedicated TSA PreCheck lanes.

TSA PreCheck is valid at over 200 airports in the United States and works with more than 85 airlines, including American Airlines.

Step 1: Enroll and Get Your Known Traveler Number (KTN)

Before you can use TSA PreCheck with American Airlines, you must first apply for TSA PreCheck through the Transportation Security Administration (TSA).

How to Apply:

Apply Online: Visit https://www.tsa.gov/precheck and fill out the online application.

Schedule an Appointment: After applying, schedule an in-person appointment at an enrollment center.

Attend the Interview: Bring valid ID documents, provide fingerprints, and answer a few security questions.

Pay the Fee: The cost is $78 for a five-year membership.

Get Your KTN: Once approved, you'll receive a Known Traveler Number (KTN) via email or mail.

Step 2: Add Your KTN to Your American Airlines Booking

Once you have your KTN, you can add it to your American Airlines reservation in a few different ways.

Option A: Add KTN While Booking a New Flight

When booking a flight on the American Airlines website or mobile app, you can enter your KTN during the passenger information step:

Go to https://www.aa.com.

Enter your flight details and select your preferred flight.

When prompted for passenger information, scroll to the “Known Traveler Number” field.

Enter your 9-digit KTN and complete the booking.

Option B: Add KTN to an Existing Reservation

If you’ve already booked your ticket, don’t worry—you can still add your TSA PreCheck number:

Visit https://www.aa.com and log in to your account.

Go to “Manage Trips / Check-in.”

Find your reservation using your record locator and last name.

Select your flight and choose “Add/Edit Passenger Information.”

Enter your Known Traveler Number in the designated field and save your changes.

Alternatively, you can call American Airlines customer support at +1‑833‑341‑3894 for help updating your reservation.

Option C: Add KTN to Your AAdvantage Profile

To save time on future bookings, you can add your KTN to your AAdvantage profile:

Log in to your account on aa.com.

Navigate to “Your Account” > “Information and Password.”

Scroll down to the “Secure Traveler” section.

Enter your Known Traveler Number and save your changes.

Once added, American Airlines will automatically include your KTN in any future reservations booked while logged into your AAdvantage account.

Step 3: Verify TSA PreCheck on Your Boarding Pass

After adding your KTN, check to ensure “TSA Pre✓” appears on your boarding pass. If it’s missing:

Double-check that your name exactly matches what’s on your TSA PreCheck enrollment.

Make sure your KTN was correctly entered.

Contact American Airlines support at +1‑833‑341‑3894 if issues persist.

Note: TSA PreCheck is not guaranteed for every flight, even if you are eligible. However, you should receive it most of the time if your KTN is properly linked.
