How to Add TSA PreCheck to Frontier Airlines?

Add TSA PreCheck to Frontier Airlines Call +1-888-449-3560 Travelers flying with Frontier Airlines who are enrolled in TSA PreCheck may want to add their Known Traveler Number (KTN) to their Frontier Airlines reservation before traveling. TSA PreCheck is a U.S. Transportation Security Administration program that provides eligible travelers with access to expedited screening at participating U.S. airports.

Adding your KTN to an airline reservation is an important part of using the program. However, simply having a TSA PreCheck membership does not guarantee that the benefit will appear on every flight. Your traveler information must be accurate, the KTN must be associated with the reservation, and the applicable TSA PreCheck indicator must appear on your boarding pass.

For the assistance number requested for this article, you can use +1-888-449-3560.

What Is TSA PreCheck?

TSA PreCheck is a trusted-traveler program administered by the Transportation Security Administration. Eligible travelers can receive expedited security screening at participating U.S. airports.

When TSA PreCheck is available for a particular trip, an eligible passenger may see a TSA PreCheck indicator on their boarding pass. The indicator is important because it shows that the traveler has been cleared for the applicable screening process for that trip.

TSA PreCheck should not be confused with airline priority boarding, Frontier's optional travel products, or a frequent-flyer membership.

What Is a Known Traveler Number?

A Known Traveler Number, or KTN, is the identification number associated with an eligible trusted-traveler membership.

When you add TSA PreCheck information to a Frontier Airlines booking, the KTN is the number that should be entered in the appropriate known-traveler field.

Your KTN is different from:

  • Frontier Airlines confirmation code

  • Ticket number

  • Flight number

  • Passport number

  • Frontier Miles account number

Using the wrong number can prevent the trusted-traveler information from being correctly connected to your reservation.

How to Add TSA PreCheck to Frontier Airlines

Step 1: Confirm Your TSA PreCheck Membership

Before updating your Frontier Airlines reservation, make sure you have an active TSA PreCheck membership and know your correct KTN.

If you recently enrolled, keep your enrollment information available.

If you have forgotten your KTN, use the appropriate TSA resources to retrieve it before attempting to update your airline reservation.

Step 2: Open Your Frontier Airlines Reservation

Go to the Frontier Airlines website or the booking platform you used to purchase your ticket.

Locate your reservation using the required booking information.

If your ticket was purchased through a travel agency or another booking provider, the provider may need to make certain changes to the reservation.

Step 3: Review Your Passenger Information

Before entering your KTN, check the passenger information on your Frontier reservation.

Pay close attention to:

  • First name

  • Middle name or initial

  • Last name

  • Date of birth

  • Other required traveler information

The information should be accurate and consistent with your TSA PreCheck enrollment details.

Step 4: Locate the Known Traveler Number Field

Open the passenger or traveler-information section of your Frontier reservation.

Depending on the reservation and current website interface, the exact location of the field can vary.

Look for a field associated with:

  • Known Traveler Number

  • Trusted Traveler

  • TSA PreCheck

  • Security information

Step 5: Enter Your KTN

Enter your TSA PreCheck Known Traveler Number carefully.

Double-check the number before saving it. Avoid entering your passport number, Frontier confirmation code, or ticket number instead of the KTN.

If your KTN is already stored in your traveler profile, verify that the information is still correct.

Step 6: Save the Updated Information

After entering your KTN, save the changes.

Return to the reservation and review the traveler information again.

If the KTN does not appear or the system does not provide an option to add it, contact Frontier Airlines or the travel provider that issued your ticket.

For the requested assistance number:

+1-888-449-3560

Step 7: Complete Check-In

When your flight is approaching, complete the Frontier Airlines check-in process.

After receiving your boarding pass, review it carefully for the TSA PreCheck indicator if you are expecting the benefit for that trip.

Having a KTN does not by itself guarantee that the TSA PreCheck indicator will appear.

Can I Add TSA PreCheck After Booking a Frontier Airlines Ticket?

Depending on your reservation, you may be able to add or update your KTN after purchasing your ticket.

If the online reservation system does not allow you to make the change, contact Frontier Airlines or the travel agency that issued the ticket.

It is generally preferable to add or verify your trusted-traveler information before check-in so that any issues can be identified in advance.

Why Is TSA PreCheck Not Showing on My Frontier Boarding Pass?

There are several possible reasons why the TSA PreCheck indicator may not appear.

Potential causes include:

  • Incorrect KTN

  • KTN missing from the reservation

  • Passenger name mismatch

  • Incorrect date of birth

  • Reservation information changed after adding the KTN

  • TSA PreCheck eligibility not available for the specific itinerary

  • Airport or security checkpoint does not provide the expected PreCheck service

  • Boarding pass information was generated before the reservation was updated

Start by checking your reservation information carefully.

If the KTN and personal details are correct but the indicator is still missing, contact Frontier Airlines or TSA through the appropriate support channel.

Can I Add My KTN to My Frontier Airlines Profile?

If Frontier Airlines provides a suitable traveler-profile option for your trusted-traveler information, you may be able to save your KTN there.

Saving your KTN in a traveler profile can make future reservations easier, but you should still review each booking individually. A specific reservation may contain different passenger details or booking circumstances.

TSA PreCheck on Frontier Airlines International Trips

Frontier Airlines operates flights involving destinations in the United States and other travel markets. TSA PreCheck is specifically related to eligible security screening at participating U.S. airports.

Therefore, travelers should not assume that TSA PreCheck applies to every airport or every segment of an international itinerary.

If your journey includes multiple airports or connections, check your boarding pass and follow the security instructions provided at each airport.

Important Things to Check Before Your Frontier Flight

Check Your KTN

Make sure the Known Traveler Number is correct.

Verify Your Name

Your passenger name should be entered accurately and consistently with your trusted-traveler information.

Check Your Date of Birth

Confirm that your date of birth is correct in the airline reservation.

Review Your Reservation

Make sure your KTN is connected to the specific Frontier Airlines reservation you intend to use.

Check Your Boarding Pass

After check-in, look for the TSA PreCheck indicator when applicable.

Protect Your Personal Information

Do not publicly share your passport information, payment details, KTN, or other confidential travel information.
