How To Add Known Traveler Number To Alaska Airlines

To add your Known Traveler Number to Alaska Airlines, go to "Profile and Settings" in the navigation menu, then click "Travel documents" under the "About you" section. You must first obtain a KTN by enrolling in a trusted traveler program like TSA PreCheck through the TSA website, which requires an application and an in-person appointment.

Step 1: Registering for a Known Traveler Number (KTN)

The most popular program is TSA PreCheck, which offers expedited security screening at participating airports across the United States.

To register for a KTN, follow these steps:

  1. Visit the Transportation Security Administration (TSA) website and click on the "Apply Now" button.
  2. Fill out the online application form with your personal information, including your full name, date of birth, and contact details.
  3. Pay the non-refundable application fee. Check the current fee on the TSA website, as it is subject to change.
  4. Schedule an appointment at an enrollment center near you. During the appointment, you will be required to provide identification documents, such as a valid passport or driver's license, and have your fingerprints taken.
  5. Once your application is approved and your background check is completed, you will receive a Known Traveler Number (KTN) via mail or email.

Obtaining a KTN does not guarantee TSA PreCheck on every flight, as eligibility is determined per flight. However, it significantly increases your chances of expedited screening. Once you have your KTN, proceed to add your known traveler number to an existing Alaska Airlines profile by navigating to "Profile and Settings," then "Travel documents" under the "About you" section.

Step 2: Accessing Alaska Airlines Website

To add your Known Traveler Number (KTN) to your Alaska Airlines profile, access the Alaska Airlines website. Follow these steps:

  1. Open your web browser on your computer or mobile device.
  2. Type www.alaskaair.com in the address bar and press Enter.
  3. You will be directed to the Alaska Airlines homepage.
  4. If you already have an Alaska Airlines account, proceed to Step 3. Otherwise, click "Sign in" at the top-right corner to create a new account.
  5. Enter your login credentials (username or Mileage Plan number and password) and click "Sign in".
  6. Once signed in, look for the "Profile and Settings" option in the navigation menu. Click on it, then navigate to "Travel documents" under the "About you" section to access your account details.

You must have a valid Alaska Airlines account to add your KTN. If you don't have one, create it by providing the required information. An account lets you manage your profile, access booking details, and add benefits like TSA PreCheck. To add your known traveler number to an existing profile, you will use the "Travel documents" section, not "Travel Preferences" or "Security Settings".

Step 3: Navigating to the "My Account" Section

Once signed into the Alaska Airlines website, navigate to your profile settings to add your Known Traveler Number (KTN). Follow these steps:

  1. On the Alaska Airlines homepage, locate the navigation menu at the top of the page or in a drop-down menu on mobile devices.
  2. Look for the "Profile and Settings" option in the navigation menu.
  3. Look for the "Travel documents" option under the "About you" section within your profile settings.
  4. Click to open "Travel documents," where you can view and modify your account information, including adding your Known Traveler Number.

It is worth noting that the specific layout and design of the website may vary, but the steps to navigate to the correct section should remain similar. If you encounter difficulties, refer to the website’s help or search for specific instructions.

With the "Travel documents" section now accessible, you are ready to proceed to the next step and add your Known Traveler Number.

Step 4: Locating the "Known Traveler Number" Option

After accessing the "Profile and Settings" section of the Alaska Airlines website, you need to locate the specific option to add your Known Traveler Number (KTN) to your profile. Follow these steps:

  1. Click on "Travel documents" to access the relevant settings.
  2. Scan through the available options and look for a section specifically related to TSA PreCheck, trusted traveler programs, or Known Traveler Numbers.
  3. Within that section, search for an option that allows you to add or edit your Known Traveler Number.
  4. Take note of any additional instructions or requirements provided on the page, as these may include important information on how to add your KTN correctly.

If you are having trouble locating the option, refer to the website's help section or search for instructions specific to Alaska Airlines' account settings related to known traveler programs. Alternatively, you can contact Alaska Airlines customer service for assistance.

Once you have located the "Known Traveler Number" option, it's time to move on to the next step and enter your KTN into your Alaska Airlines profile.

Step 5: Entering Your Known Traveler Number

Now that you have located the entry field, follow these steps to add your Known Traveler Number (KTN):

  1. Click on the "Known Traveler Number" option to access the entry field.
  2. Enter your 9-digit KTN in the provided text box. Double-check the number for accuracy.
  3. If prompted, fill in additional fields like your TSA PreCheck expiry date or membership details.
  4. Review your entries to ensure all information is correct.

Be mindful of formatting requirements: some websites require dashes or spaces between digits. Follow the specified format to ensure your KTN is accepted. If you have multiple KTNs from different trusted traveler programs, check if the system allows you to enter all relevant numbers to receive the appropriate benefits for each program.

Once you have entered your KTN and any additional information, save your changes to register the number with your Alaska Airlines profile. To add your known traveler number to an existing reservation, you may need to repeat these steps on the booking details page.

Step 6: Saving Your Changes

After entering your Known Traveler Number (KTN) into your Alaska Airlines profile, save your changes to ensure your KTN is successfully added. Follow these steps:

  1. Look for a "Save" or "Apply" button near the entry field where you input your KTN.
  2. Click the "Save" or "Apply" button to store your changes.
  3. Wait for a confirmation message or notification, such as a pop-up or green checkmark, indicating your changes were saved.
  4. Review your profile to confirm your KTN is displayed correctly.
  5. If any verification steps are required, follow the instructions provided, which may include verifying your identity or confirming your trusted traveler program participation.

Without saving, your KTN may not link to your account, and you may not receive PreCheck benefits. If you encounter an error, double-check your entries and try again. If the problem persists, contact Alaska Airlines customer service.

Once saved, you can verify your KTN is added to your profile. To add your known traveler number to an existing reservation, ensure you have saved it in your profile first.

Step 7: Verifying Your Known Traveler Number is Added

After saving your changes, verify your Known Traveler Number (KTN) is correctly linked to your Alaska Airlines profile:

  1. Verify that your 9-digit Known Traveler Number is displayed accurately and matches the number you entered.
  2. Click to view or edit your KTN to confirm it is saved correctly.
  3. Take a screenshot or note your KTN for future reference.

Confirming your KTN ensures your eligibility for expedited security screenings, such as TSA PreCheck. To add your known traveler number to an existing reservation, repeat this process for each booking.

If you find errors, use the editing options to make corrections. For assistance, contact Alaska Airlines customer service. With verification complete, your KTN is correctly associated with your profile for expedited screenings.

Adding your Known Traveler Number (KTN) to your Alaska Airlines profile is a straightforward process that can greatly enhance your travel experience. By following the steps outlined in this guide, you can ensure that your KTN is properly linked to your account, allowing you to enjoy the benefits of expedited security screenings and a smoother journey through airport checkpoints.
