How to Add KTN to DELTA After Booking Flight

How to Add KTN to DELTA after Booking Flight

Are you a frequent flyer? Do you wish to escape the long queues of airport security checks? If yes, then you need to enroll yourself in the Trusted Traveller Program. 

This program allows you to carry your luggage with you without taking everything out while going through the security line. Also, you will be allowed to keep on your jackets or light outerwear and belts. 

After enrolling in the Trusted Traveller Program, you will be receiving a KTN, i.e. Known Traveller Number. 

You need to enter this number whenever you are booking your flights through American Airlines or Delta airlines, or any other participating airlines for a TSA precheck security screening line. If you don’t do that, you will not be allowed to enter these security lines. 

Well, sometimes you might forget to add your known Traveller Number or give your KTN to the travel agency while booking your tickets. In that case, there are many ways you can add your KTN to your airlines after booking the tickets and in this article, we will learn about the same.

To make your journey comfortable and easy, we have provided you different options for adding your ‘Known Traveler Number’ to your account. Before jumping to the ways, let us first understand what KTN is and what are the benefits.

What is a Known Traveller Number (KTN)?

A Known Traveller Number (KTN) is also known as Trusted Traveller Number, which is issued by the U.S Transportation Security Administration, Department of Defence, or Department of Homeland Security. 

This number specifies that you have undergone a screening or pre-flight background check before boarding a flight. The preflight background check makes your airport visit more comfortable and convenient.

There, you will have a different screening lane at participating U.S airports, wherein you don’t have to remove your jackets, shoes, belts, and laptops from the carry-on bag. Your KTN even permits you to take benefits of expedited customs processing at the participating airports.

These aspects of the traveler program are very beneficial for making the screening process quicker and easier especially on busy travel days.
