How To Add Known Traveler Number To Delta Air Lines

To add your Known Traveler Number to Delta Air Lines, sign in to your account, go to Profile Settings, and enter the number in the Secure Flight Passenger Data section. You can only add your personal KTN to your own Delta account, not to group or corporate reservations. Once signed in on the Delta homepage, click your name or the Profile link, find the TSA PreCheck/Global Entry section, and type in your nine-digit KTN—then save the change to apply it to future bookings.

Step 1: Sign in to your Delta Air Lines account

The first step to adding your Known Traveler Number (KTN) to your Delta Air Lines account is to sign in. If you don't have an account yet, you can create one on the Delta website.

On the Delta Air Lines homepage, look for the "Sign In" option at the top right corner of the screen. Click on it, and proceed to the sign-in page.

On the sign-in page, enter your SkyMiles Number or username and password. If you have a SkyMiles Number, use it in the designated field. Otherwise, use the username and password associated with your account. Click "Sign In" to access your account.

If you forget your SkyMiles Number or username, use the "Forgot SkyMiles Number" or "Forgot Password" links on the sign-in page. Follow the on-screen instructions to recover your account details.

Your Known Traveler Number can only be added to your personal Delta account. If you are part of a group reservation or using a corporate travel account, contact the appropriate entity to add your KTN to the reservation. If you need to add your Delta SkyMiles number to an existing reservation, you can often do so during the booking process or by contacting customer service.

Once signed in, you're ready to proceed to the next step of adding your Known Traveler Number.

Step 2: Go to your profile settings

Now that you've signed in to your Delta Air Lines account, the next step is to navigate to your profile settings. This is where you can make various updates and additions to your account information, including your Known Traveler Number.

To access your profile settings, navigate to your account's main page. This will take you to the main page of your account, where you can manage your bookings, view your miles, and make changes to your profile settings.

On this page, look for the "Profile" or "Account Settings" section, as the exact labeling may vary slightly. Once you've located it, click on it to reveal the different profile settings available.

Within the profile settings, you may find options to update your contact information, email preferences, and security settings. However, for adding your Known Traveler Number, you need to locate the section specifically related to security.

This section may be labeled as "Secure Flight Passenger Data" or "TSA PreCheck/Global Entry". Click on this section to access the settings related to your travel information and security clearances.

This step is crucial because it takes you to the section where you can add and manage your Known Traveler Number. Once you've reached the appropriate page, you're ready to advance to the next step and add your KTN to your Delta Air Lines account.

Step 3: Navigate to the Known Traveler Number section

Now that you've accessed the profile settings page of your Delta Air Lines account, it's time to locate the section for your Known Traveler Number (KTN). This section allows you to add, update, or remove your KTN from your account.

Scroll through the options and settings within the profile settings until you find a subsection related to your security clearances or Trusted Traveler Programs. This is where you can manage your KTN and other similar travel-related information.

Depending on the layout of the page and the specific design of Delta Air Lines' website at the time, this section may be labeled as "TSA PreCheck/Global Entry". Look for any option that indicates the management of your KTN. If you're unsure, you can use the search function on the page to quickly locate the desired section.

Once you've found the section, click on it to access the corresponding settings page. This is where you'll be able to add your KTN to your Delta account and take advantage of TSA PreCheck benefits. To add your known traveler number to an existing reservation, you would also use this same section.

It's worth noting that some airlines may have a separate subsection for Global Entry members, so if you're a Global Entry participant, explore that section as well to ensure your information is correctly associated with your account.

Now that you've navigated to the Known Traveler Number section, you're ready for the next step of actually adding your KTN. Let's proceed!

Step 4: Add your Known Traveler Number

Now that you've located the section dedicated to your Known Traveler Number (KTN) within your Delta Air Lines account, it's time to add your KTN. This step ensures that your KTN is associated with your account, allowing you to enjoy the benefits of TSA PreCheck.

Within the Known Traveler Number section, you'll typically find a designated field or input box where you can enter your KTN. Click on this field to activate it and ensure your cursor is positioned correctly.

Next, retrieve your Known Traveler Number from your TSA PreCheck membership card, Global Entry card, or any other official document confirming your participation in a Trusted Traveler Program. Carefully enter your KTN in the input box, double-checking that you've entered the correct characters and numbers. It's crucial to enter your KTN accurately to ensure a seamless experience during security screening.

If you're having trouble locating your Known Traveler Number, check your Trusted Traveler Program account online. They often provide access to your KTN information, making it easier to ensure accuracy and avoid issues during the boarding process.

Once you've entered your KTN, review the information you've provided. Ensure your KTN is accurate and complete. If you need to make adjustments, use the backspace or delete key to erase the existing entry and retype it correctly.

Additionally, some airlines may offer an option to provide additional details or add remarks related to your Known Traveler Number. If such an option is available, you can use it to include any relevant notes for Delta Air Lines regarding your KTN.

After you've added your Known Traveler Number to the designated field and reviewed your entry, you're ready to move on to the next step and save your changes.

Step 5: Save your changes

After adding your Known Traveler Number (KTN) to your Delta Air Lines account, look for a "Save" or "Update" button within the section where you entered your KTN. This button is typically located at the bottom of the page or near the input box.

Click the "Save" or "Update" button to apply the changes. The system will validate the entered KTN and update your profile accordingly. During the saving process, avoid navigating away from the page or closing the browser tab or window, as doing so prematurely may result in the changes not being saved.

Once saved, a confirmation message or notification will usually appear on the screen, verifying that your Known Traveler Number has been added to your Delta profile successfully. Take a moment to verify the accuracy of the added KTN and double-check that it matches the information on your TSA PreCheck or Trusted Traveler Program documentation.

By saving your changes, you have completed the process of adding your Known Traveler Number to your Delta Air Lines account. The next step involves verifying that your KTN has been added correctly, ensuring a smooth travel experience with TSA PreCheck benefits. If you need to add your known traveler number to an existing reservation, you may also need to update that booking separately.

Step 6: Verify your Known Traveler Number is added

Once you have saved your changes and added your Known Traveler Number (KTN) to your Delta Air Lines account, it's crucial to verify that it has been added correctly. Verifying your KTN ensures that you'll enjoy the benefits of TSA PreCheck during your travels.

To verify your KTN, navigate back to your profile settings or account overview page within your Delta Air Lines account. Look for the section where you added your KTN in Step 4.

Within this section, you should see your Known Traveler Number displayed. Take a moment to carefully read and confirm that the KTN matches the one you entered earlier. Verify that all the characters and numbers are accurate.

If you have multiple accounts, such as a SkyMiles account and a profile for a corporate travel program, ensure that your KTN is associated with the correct account. Double-checking this information is important to prevent any confusion during the airport security screening process.

If you notice any discrepancies or errors in your Known Traveler Number, you can go back to the Known Traveler Number section and make the necessary corrections. Simply follow the steps outlined in Step 4 to edit or update your KTN.

Additionally, it's advisable to print or take a screenshot of your KTN confirmation page or take note of your KTN for your records. Having this information readily available can be helpful, especially if you need to provide your KTN to the airline at a later stage or during check-in.

With the verification process complete, you can have peace of mind knowing that your Known Traveler Number is correctly associated with your Delta Air Lines account. This ensures a hassle-free experience with TSA PreCheck, allowing you to breeze through airport security lines and enjoy a smoother travel journey.
