How to Add TSA PreCheck to United Airlines?

 Add TSA PreCheck to United Airlines Call +1-888-449-3560 Travelers flying with United Airlines who are enrolled in TSA PreCheck can add their Known Traveler Number (KTN) to their United reservation or MileagePlus profile. Correctly providing your KTN and matching your personal information can help ensure that your TSA PreCheck eligibility is properly associated with your trip.

TSA PreCheck is administered by the Transportation Security Administration and is intended for eligible travelers using participating airport security checkpoints in the United States. Having a membership does not automatically guarantee expedited screening on every trip, so it is important to enter your information correctly and check your boarding pass before traveling.

For assistance with the reservation process, the requested helpline number is +1-888-449-3560.

What Is TSA PreCheck?

TSA PreCheck is a trusted-traveler program that allows eligible travelers to receive expedited security screening at participating U.S. airports.

When TSA PreCheck is available for a particular trip, the traveler normally receives a TSA PreCheck indicator on the boarding pass. The indicator tells the traveler that they can proceed to the designated TSA PreCheck screening lane, where available.

Simply having TSA PreCheck membership does not mean that every flight automatically receives the benefit. The traveler must meet the applicable requirements and have the correct information associated with the reservation.

What Is a Known Traveler Number?

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

Your KTN is different from your:

  • United Airlines confirmation number

  • Ticket number

  • Flight number

  • Passport number

  • MileagePlus number

When updating your United Airlines reservation, make sure you enter your actual KTN in the appropriate field.

How to Add TSA PreCheck to United Airlines

Step 1: Confirm Your TSA PreCheck Information

Before changing your United reservation, make sure you have your valid KTN available.

If you recently enrolled in TSA PreCheck, verify that your membership information is active and that you have the correct number.

If you have forgotten your KTN, use the appropriate TSA resources to retrieve it before updating your airline information.

Step 2: Sign In to Your United Airlines Account

Open the United Airlines website or mobile application and sign in to your account.

If you have a MileagePlus account, review the traveler information associated with your profile. Keeping your KTN in your traveler profile can make it easier to associate your trusted-traveler information with future reservations.

Step 3: Locate Your Reservation

If you have already booked a United Airlines flight, open the reservation through the booking-management section.

You may need your confirmation number and passenger information to retrieve the booking.

Choose the appropriate trip and review the passenger details.

Step 4: Open Traveler or Personal Information

Look for the section where United allows you to manage passenger or traveler information.

Depending on the booking and current United interface, the location and wording of traveler-information fields can vary.

Look for a field related to:

  • Known Traveler Number

  • Trusted Traveler information

  • TSA PreCheck

  • Security information

Step 5: Enter Your KTN

Enter your TSA PreCheck Known Traveler Number carefully.

Double-check every digit before saving the information. Do not enter your passport number, ticket number, or United confirmation number in the KTN field.

If your KTN is already stored in your United traveler profile, verify that it is correct and associated with the reservation.

Step 6: Check Your Personal Details

Your personal information should be accurate and consistent with your trusted-traveler enrollment.

Pay particular attention to:

  • First name

  • Middle name or initial

  • Last name

  • Date of birth

An incorrect or inconsistent name can interfere with the expected TSA PreCheck information being associated with your reservation.

Step 7: Save the Changes

After entering or updating your KTN, save the information.

Return to your reservation and review the traveler details to confirm that the update was retained.

If you booked through a travel agency or another travel website, you may need to contact the organization that issued the reservation.

Step 8: Complete United Airlines Check-In

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

After receiving your boarding pass, check whether the TSA PreCheck indicator is displayed if you are eligible for PreCheck on that journey.

Do not rely solely on your membership card or KTN. The boarding pass is important because it indicates whether the TSA PreCheck benefit is available for that particular trip.

Can I Add TSA PreCheck After Booking a United Flight?

Yes, travelers can generally provide or update trusted-traveler information after making an airline reservation, subject to the options available for the specific booking.

If the online reservation does not allow you to add or modify your KTN, contact United Airlines or the travel agency that issued your ticket.

For the requested assistance number:

+1-888-449-3560

When contacting support, keep your confirmation number and general flight information available. Avoid sharing sensitive information publicly.

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

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

Common issues include:

  • Incorrect KTN

  • KTN not attached to the reservation

  • Name mismatch

  • Incorrect date of birth

  • Traveler information changed after the KTN was added

  • Eligibility not available for the specific trip

  • The particular airport or security checkpoint does not provide the expected PreCheck service

  • Boarding pass information was generated before the reservation was properly updated

First, review your United reservation and verify your KTN and personal information.

If everything appears correct and the TSA PreCheck indicator is still missing, contact United Airlines or TSA for assistance.

Can I Add TSA PreCheck to My United MileagePlus Profile?

Travelers may store trusted-traveler information in their United traveler profile when the appropriate profile fields are available.

Adding your KTN to your profile can make it easier to associate the information with future reservations. However, you should still verify each individual booking because reservations can contain different passenger information or booking circumstances.

TSA PreCheck for United International Flights

United Airlines operates both domestic and international flights. TSA PreCheck relates to eligible security screening in the United States, so travelers should not assume that the benefit applies to every airport or every segment of an international itinerary.

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

Important Things to Check Before Your Flight

Before traveling with United Airlines, verify:

Your KTN

Make sure the Known Traveler Number is correct.

Your Name

Check that your first and last name are entered accurately.

Your Date of Birth

Verify your date of birth because incorrect personal information can cause traveler-information problems.

Your Reservation

Make sure your KTN is associated with the specific United booking you intend to use.

Your Boarding Pass

After checking in, review your boarding pass for the TSA PreCheck indicator when applicable.

Your Personal Information

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

If you have a United MileagePlus profile, you can also review the trusted-traveler information stored in your account when the relevant option is available. After updating your information, check the specific reservation rather than assuming that the profile update automatically guarantees PreCheck on every trip.

Before going to the airport, complete check-in and examine your boarding pass. If the TSA PreCheck indicator appears, follow the airport's instructions for the designated screening lane. If it does not appear, review your information and contact the appropriate airline or TSA support channel.
