How to add Known Traveler Number(KTN) delta ?

To add your Known Traveler Number (KTN) to your Delta Air Lines reservation, you can follow these steps:

1. Access Your Reservation: Log in to your Delta Air Lines account on the official Delta website.
2. Retrieve Your Reservation: Locate your upcoming flight reservation for which you want to add the Known Traveler Number.
3. Manage Your Booking: Once you’ve found your reservation, look for an option to manage or view the details of your booking. This may be labeled as “Manage My Booking” or “My Trips.”
4. Enter Passenger Information: Navigate to the section where you can view or edit passenger details. Here, you should find an option to add or update Secure Flight Passenger Data, which includes your Known Traveler Number.
5. Add Known Traveler Number: Enter your Known Traveler Number (KTN) into the appropriate field. Double-check the number to ensure accuracy.
6. Save Changes: After entering your Known Traveler Number, save the changes to your reservation. Delta may prompt you to confirm the updates before proceeding.
7. Verify Information: Review your reservation details to confirm that your Known Traveler Number has been successfully added. You may also receive a confirmation email from Delta with the updated information.
8. Check-In: When it’s time for your flight, complete the check-in process either online or at the airport. Your Known Traveler Number will be included in your Secure Flight Passenger Data, allowing you to potentially enjoy expedited security screening through TSA PreCheck lanes if eligible.

It’s important to note that while Delta offers the option to add your Known Traveler Number online, you should also ensure that your TSA PreCheck membership is active and that your KTN is associated with your TSA PreCheck eligibility. This will help you enjoy the benefits of expedited security screening during your travels.
