Is it time for take off... again?


In the coming weeks, the Transportation Security Administration (TSA) will make changes to its Pre® program, which may affect frequent flyer eligibility. SkyMiles members who previously “opted-in” to receive TSA Pre®may notice a significant reduction in the number of times they are chosen for expedited screening. This is due to an increase in the number of passengers who are eligible, as well as an increase in the number of passengers who pay to participate in Trusted Traveler Programs.

SkyMiles Members

SkyMiles members who are currently enrolled in a trusted traveler program (TSA Pre®, Global Entry, NEXUS, SENTRI) and/or have been issued a Known Traveler Number (KTN)/PASSID which is included in their reservations will continue to receive TSA Pre®on a consistent and predictable basis and no further action is required. 

Delta encourages all customers, including SkyMiles members, who are not currently enrolled in a Trusted Traveler Program to consider enrolling. This includes SkyMiles Members who had received an invitation from Delta to participate as a frequent flyer in TSA Pre® but who do not have a Known Traveler Number (KTN)/PASSID. Customers who already have a KTN/PASSID should be sure to log in at and add it to “My Profile.” 

Trusted Traveler Programs 

The Department of Homeland Security (DHS) has four Trusted Traveler programs, which are customized based on travel needs. For guidance on which program may be best for an individual, please click here for acomparison chart. For details and application forms for each program, click on the links below:

1. TSA Pre® application program is valuable for travelers who primarily fly within the U.S.
2. Global Entry – for travelers who fly both within the U.S. and internationally
3. NEXUS – for travel primarily between the U.S. and Canada
4. SENTRI – for those who travel primarily by land into the U.S. from Mexico

Information for Travel Partners

The name, date of birth and gender used in the Trusted Traveler program application is the information that must match that which is used in the Secure Flight Passenger Data (SFPD) when booking travel. While the passenger name field in the PNR may vary due to name field restrictions on number of characters, the SFPD information must match and is used for vetting by the TSA.

Frequently Asked Questions 

What is a Known Traveler Number (KTN)/PASSID?
After completion of the vetting process or a background check, as part of their employment or via a DHS Trusted Traveler program, when determined eligible, the passenger will be issued a KTN/PASSID (also may be referred to as a PASSID) by TSA or Custom Border Patrol (CBP). Since the TSA knows more about these passengers they are more likely to be eligible for TSA Pre®screening more often than passengers the agency knows less about.

Due to differences in the Trusted Traveler programs, the Known Traveler Number (KTN) may be referred to as a PASSID, or TT (Trusted Traveler) number. The number of digits may vary from seven to 10 digits.

I have a KTN/PASSID, what do I need to do? 

1. When confirming reservations on, provide the KTN/PASSID in the ‘Known Traveler Number’ field. When confirming reservations with a travel agency, corporate travel department or Delta Reservations, provide the KTN/PASSID to the representative.

SkyMiles Account
2. Log in to your SkyMiles account and visit Basic Info in your profile. Add your KTN/PASSID, and it will then be stored for future reservations. Your KTN/PASSID must be saved to each of any existing reservations prior to check-in for each flight to be considered for TSA Pre®.

Prior to Travel
3. Prior to traveling, to confirm, go to, log in to your account, enter your passenger information, and verify if “Passenger Information and Secure Flight Passenger Data” is correct.

I book my travel with my agency or corporation, what should I do? 
Customers who are enrolled in a Trusted Traveler Program should ensure that their KTN/PASSID has been added to their company travel profile or reservation. It is also recommended to verify that the name, Date of Birth (DOB), gender and KTN/PASS ID is correctly entered in the profile and in the reservation.
