Adding TSA PreCheck to an American Airlines reservation is simple once you have a valid Known Traveler Number. You can save the number in your AAdvantage account for future trips or add it to one existing booking. The most important step is confirming that the TSA PreCheck indicator appears on your boarding pass before you head to security.
Quick Answer
To add TSA PreCheck to American Airlines, enter your KTN or CBP PASS ID in the Secure traveler section of your AAdvantage profile or in Security information for an existing trip. Save the update, then get a new boarding pass if you already checked in. The TSA PreCheck indicator must appear before you use the lane.
Key Takeaways
- AAdvantage members can save a KTN or PASS ID in the Secure traveler section so it applies to future bookings made while signed in.
- For an existing trip, open the reservation, edit the passenger information, and add the number under Security information.
- Your name and date of birth must match the information connected to your TSA PreCheck membership.
- If you add the number after checking in, obtain a new boarding pass and look for the TSA PreCheck indicator.
- Membership makes you eligible for expedited screening, but TSA does not guarantee it for every trip.

What TSA PreCheck Does
TSA PreCheck is an expedited airport security program for eligible, vetted travelers. At participating checkpoints, members generally use a dedicated lane and may leave their shoes, belt, and light jacket on. They may also be allowed to keep laptops and compliant 3-1-1 liquids inside their carry-on bags.
These benefits can reduce the number of items you must unpack and repack. That is especially helpful during busy travel periods, when traveling with children, or when managing mobility equipment and multiple carry-on items.
Note: TSA may use additional or standard screening at any time. Membership does not guarantee that you will receive expedited screening on every trip.
Benefits of TSA PreCheck
- Dedicated screening lanes: Participating airports may provide separate lanes for eligible travelers.
- Less unpacking: Laptops and compliant liquids can generally remain in your carry-on bag.
- Fewer clothing items to remove: Members can usually keep shoes, belts, and light jackets on.
- Five-year membership: A standard membership remains valid for five years unless it is suspended or revoked.
- Airline-profile storage: American Airlines lets AAdvantage members save their KTN or PASS ID for future bookings.
The actual wait depends on the airport, checkpoint hours, passenger volume, and whether a TSA PreCheck lane is open. Travelers should still arrive with enough time to check bags, pass security, and reach the gate.
Who Is Eligible for TSA PreCheck?
The TSA PreCheck Application Program is open to U.S. citizens, U.S. nationals, and lawful permanent residents. Applicants must complete identity verification and a security-threat assessment.
A criminal record does not automatically produce the same result in every case. TSA maintains a list of disqualifying offenses and other eligibility factors. Some offenses permanently disqualify an applicant, while others may be disqualifying for a defined period.
Applicants must provide acceptable identity and citizenship or immigration documents. The enrollment provider also collects fingerprints, a photograph, and biographic information during the in-person visit.
How to Apply for TSA PreCheck
- Start through TSA’s official site. Visit the TSA PreCheck enrollment page and choose an authorized enrollment provider.
- Complete the online application. The initial form normally takes only a few minutes.
- Schedule an enrollment visit. Select an available location and bring the required original or certified identification documents.
- Complete identity verification. The provider reviews your documents and collects fingerprints, a photograph, and the required personal information. A typical appointment takes about 10 minutes.
- Pay the provider’s fee. TSA currently advertises five years of membership for $85 or less. The exact initial and renewal price can differ by provider.
- Wait for the decision. Most applicants receive their KTN in three to five days, although some cases can take up to 60 days.
Most applicants receive their Known Traveler Number within three to five days, but TSA advises that some applications can take up to 60 days.
Once approved, retrieve and securely store your Known Traveler Number. You do not receive a special TSA PreCheck boarding pass directly from TSA. Instead, you enter the number in your airline profile or flight reservation.
How to Add TSA PreCheck to American Airlines
American Airlines accepts a TSA-issued KTN or a PASS ID from an eligible Customs and Border Protection Trusted Traveler Program, such as Global Entry, NEXUS, or SENTRI. Enter either number in the KTN field.
Add the KTN to Your AAdvantage Profile
Saving the number in your profile is the most convenient option for frequent American Airlines travelers.
- Log in to your AAdvantage account on aa.com or in the American app.
- Open your account information or profile settings.
- Find the Secure traveler section.
- Enter your KTN or CBP PASS ID in the appropriate field.
- Confirm that your full name and date of birth match the information connected to your trusted-traveler membership.
- Save the changes.
American states that the saved number can be applied to future trips booked through your account. Make sure you are signed in when making the reservation.
Pro Tip: Add the KTN to your profile before booking. Then check each reservation after purchase to confirm that the number carried over to the correct passenger.
Add the KTN to an Existing American Airlines Trip
- Open Your trips on aa.com or in the American app.
- Locate the reservation using your account or the passenger’s name and record locator.
- Select Edit in the passenger information section.
- Open Security information.
- Enter the KTN or PASS ID for the correct passenger.
- Save the changes.
Each eligible traveler must have the correct number attached to their own passenger record. Do not add one adult’s KTN to another traveler.
Add the KTN While Booking
If you are not an AAdvantage member or do not want to save the number permanently, enter it in the Known Traveler Number field when completing the passenger information for a new reservation.
Check the entry carefully before paying. A missing character, an extra space, or a number entered in the redress-number field instead of the KTN field can prevent the indicator from appearing.
Add the KTN After Check-In
You can update an eligible reservation after booking. However, a boarding pass issued before the update may not refresh automatically.
- Add the KTN to the reservation.
- Return to the check-in or boarding-pass screen.
- Request, download, or print a new boarding pass.
- Confirm that the new pass displays the TSA PreCheck indicator.
Warning: Do not enter the security line until you have checked the boarding pass. A membership card, approval email, or KTN by itself does not authorize entry to the TSA PreCheck lane.
How to Use TSA PreCheck on an American Airlines Trip
After checking in, look for the TSA PreCheck name or symbol on your printed or mobile boarding pass. If it appears, follow airport signs to the appropriate lane.
Present the identification requested by TSA. Even where identity-verification technology is available, carry an acceptable physical ID unless official instructions for your specific airport and program say otherwise.
If no TSA PreCheck indicator appears, use the standard lane unless American Airlines updates the reservation and issues a corrected boarding pass. TSA checkpoint officers cannot edit an American Airlines passenger record.
Why TSA PreCheck May Be Missing From Your Boarding Pass
1. The KTN Was Entered Incorrectly
Compare the number in your reservation with your TSA or Trusted Traveler Program account. TSA-issued KTNs may include letters and numbers and can be nine to ten characters long. A CBP PASS ID is generally a nine-digit number.
2. Your Personal Details Do Not Match
Your full name and date of birth in the airline reservation should match the membership record. Check for:
- Misspelled first or last names
- Missing or different middle-name information
- A recently changed legal name
- An incorrect date of birth
- The KTN attached to the wrong passenger
3. You Added the Number After Check-In
Obtain a new boarding pass after saving the KTN. American specifically advises travelers to reissue the boarding pass when the number is added after check-in.
4. Your Membership Expired
Use TSA’s official membership lookup or your enrollment provider’s account to confirm the expiration date. A number can remain saved in an airline profile even after the associated eligibility expires.
5. The Trip Includes a Partner Airline
For a codeshare or partner-operated flight, confirm that the KTN is attached to the passenger record used by the airline operating the flight. Contact American Airlines or the operating carrier when the number appears in one system but not the other.
6. The Airport or Checkpoint Does Not Offer the Lane
TSA PreCheck is available through participating airlines and checkpoints. Lane hours and locations may vary, and a dedicated lane may not be open for every departure.
7. TSA Selected Standard or Additional Screening
All travelers remain subject to TSA screening. Even an active member with correct reservation information may occasionally receive standard or additional screening.
8. You Used a Redress Number in the KTN Field
A DHS redress number is not the same as a KTN. A redress number is issued through the DHS Traveler Redress Inquiry Program to travelers who experienced repeated screening or identity-matching problems. Enter each number only in its labeled field.
Note: If every detail is correct but the indicator is still missing, contact American Airlines before going through security. For membership or eligibility questions, contact TSA or your enrollment provider.
TSA PreCheck Rules for Children
Family access depends on the child’s age and reservation:
- Children 12 and under: They may accompany an eligible parent or guardian through the TSA PreCheck lane. The indicator does not have to appear on the younger child’s boarding pass.
- Children ages 13–17: They may accompany an eligible parent or guardian when traveling on the same reservation and the TSA PreCheck indicator appears on the child’s boarding pass.
- Travelers 18 and older: They need their own qualifying KTN or trusted-traveler eligibility.
Families should check every boarding pass before entering the line. TSA publishes the current details on its TSA PreCheck for Families page.
Renewing TSA PreCheck
TSA PreCheck membership lasts five years. Members can generally begin an online renewal up to six months before expiration. Starting early does not shorten the remaining membership period because the renewed period begins when the current one ends.
Renew through an authorized enrollment provider linked from the official TSA renewal page. Some members may be directed to complete an in-person visit.
You normally keep your existing KTN after renewal. Therefore, you generally do not need to replace the number in your AAdvantage profile. You should still confirm that the saved number is correct and that your name and date of birth remain current.
American Airlines TSA PreCheck Touchless ID
Eligible AAdvantage members can opt in to TSA PreCheck Touchless ID at participating airports. The optional program uses facial identity verification in a dedicated eligible lane.
American’s current enrollment process requires an eligible member to:
- Save a valid KTN in the AAdvantage Secure traveler section.
- Save valid passport information.
- Confirm that the name, date of birth, and passport number match the passport.
- Select the TSA PreCheck Touchless ID opt-in option.
- Use the American app and look for the Touchless ID symbol on the mobile boarding pass.
Participation is optional. Travelers can use a physical ID instead, and Touchless ID availability varies by airport and checkpoint.
Other Expedited Travel Programs
Global Entry
Global Entry is a U.S. Customs and Border Protection Trusted Traveler Program designed to speed entry into the United States after international travel. Approved members also receive TSA PreCheck eligibility. Enter the nine-digit CBP PASS ID in American’s KTN field.
NEXUS and SENTRI
Eligible NEXUS and SENTRI members may also receive TSA PreCheck benefits. Use the PASS ID connected to the Trusted Traveler Program membership.
CLEAR
CLEAR is a separate identity-verification service available at participating airports. It does not replace TSA screening and does not automatically include TSA PreCheck. At airports that support both programs, an eligible traveler may use CLEAR for identity verification and then proceed to the appropriate TSA screening lane.
Once your airport security setup is complete, travelers preparing for wet-weather trips can also review these waterproof travel sneaker suggestions.
