How to add TSA PreCheck to Delta +1-888-760-1051 Airlines booking? Learn simple steps to update your KTN and secure faster screening by for quick assistance.
Adding TSA Precheck to your Delta Airlines booking is one of the best ways to speed up your airport experience and reduce the hassle of long security lines. TSA Precheck allows eligible travelers to use dedicated security lanes, keep shoes and belts on, leave laptops and liquids inside bags, and clear security much faster than regular passengers. If you have already received your Known Traveler Number (KTN) from the Transportation Security Administration, the next step is to make sure it is added correctly to your Delta reservation. If the KTN is not attached to your booking, the TSA Precheck indicator will not appear on your boarding pass, and you will not be able to use the expedited lanes. Therefore, understanding the correct steps to add TSA Precheck to your Delta Airlines itinerary is essential. Whether you booked directly through Delta, used a travel agent, or added your SkyMiles information later, the process is straightforward once you know where to look.
How to Add TSA Precheck to an Existing Delta Airlines Booking
When you already have a Delta reservation but notice that your TSA Precheck is not showing on your boarding pass, you can manually enter your Known Traveler Number through the airline’s website, mobile app, or customer support. This method ensures your details are updated instantly.
Add TSA Precheck via Delta Website
The Delta Airlines website is one of the easiest ways to add your KTN to an existing booking. To begin, visit the official Delta site and sign in to your SkyMiles account if you used it during your booking. After signing in, go to the “My Trips” section and select the reservation that needs TSA Precheck added. Inside the trip details menu, look for the passenger information or profile update options. Here, you will find a field labeled “Known Traveler Number.” Enter your valid KTN exactly as provided by TSA. Once saved, Delta automatically updates your booking. After adding the number, check whether your boarding pass shows the TSA Precheck symbol, usually displayed with the word “TSA PRE” or a designated checkmark. This confirmation ensures that your information is synced properly with the TSA database.
Add TSA Precheck via Delta Mobile App
Many travelers find the Delta app more convenient because it allows quick updates without using a computer. To add TSA Precheck through the Delta app, open it and log into your SkyMiles account. Navigate to the “Trips” tab and choose the upcoming flight. Look for the passenger information section. You will see an option to edit your details. Inside the edit menu, enter your Known Traveler Number in the appropriate field. After saving the changes, refresh your itinerary and check your mobile boarding pass to ensure the TSA Precheck indicator appears. If not, try closing and reopening the app or re-adding the number. The mobile app is especially helpful for last-minute updates before heading to the airport.
Add TSA Precheck by Calling Delta Airlines Customer Service
If you booked your ticket through a travel agency, third-party website, or if the system does not allow online changes, calling Delta customer service is the best option. A representative can manually enter your Known Traveler Number into your booking. When contacting customer service, have your confirmation number and KTN ready. The agent will process the update and advise you to check your boarding pass before arriving at the airport. Adding TSA Precheck through a phone call is useful in cases where your booking has restrictions or code-share flights.
How to Add TSA Precheck to a New Delta Airlines Booking
When booking a new flight on Delta, you should always enter your Known Traveler Number during the booking process. Doing this prevents last-minute problems at the airport and ensures your boarding pass automatically includes the TSA Precheck logo.
Entering KTN During Online Booking
When booking a new Delta flight online, follow the regular steps—select your travel dates, choose flights, and proceed to passenger information. During the personal information section, Delta provides fields for full name, date of birth, gender, and other identification details. This is also where you will find the “Known Traveler Number” field. Simply enter your KTN before moving to the payment page. When the ticket is issued, TSA Precheck will already be associated with your itinerary. It is highly recommended to double-check your boarding pass after completing the booking.
Adding TSA Precheck When Booking Through the Delta App
If you prefer booking through the mobile app, the process is similar. As you enter your passenger details during booking, you will see an option to enter your Known Traveler Number. Make sure the name on the ticket perfectly matches the name associated with your TSA account. Any mismatch may prevent TSA Precheck from appearing. If submitted correctly, your digital boarding pass will show the TSA Precheck indicator when check-in opens.
Ensure Your SkyMiles Profile Contains Your Known Traveler Number
To avoid repeatedly entering your KTN for every trip, Delta allows you to save it directly in your SkyMiles profile. Once saved, Delta will automatically attach your Known Traveler Number to all future bookings as long as you are logged in while booking.
How to Update Your SkyMiles Profile
Sign in to your Delta SkyMiles account through the website or app. Navigate to your profile settings and look for the “Secure Flight Information” section. Here, you will see fields including full name, gender, date of birth, and Known Traveler Number. Enter your KTN and save the information. By saving it once, every new Delta reservation you make will include TSA Precheck automatically.
Common Reasons TSA Precheck Does Not Appear on Your Delta Boarding Pass
Sometimes, even after entering your KTN, the TSA Precheck symbol may not appear. There are several reasons this can happen, and understanding them helps you fix the issue quickly. One common reason is that the name on the booking does not exactly match the name associated with your TSA account. Even a small difference like a missing middle name or an extra hyphen can cause mismatches. Another reason is that TSA occasionally conducts random screenings where some eligible travelers may not receive TSA Precheck for a particular flight. If your KTN was entered after the booking was created, the system may take a few minutes to update, so checking your boarding pass again after some time is recommended. Code-share or partner flights operated by another airline may also affect TSA Precheck availability. Finally, ensure your KTN is still valid and correctly entered.
Tips for a Smooth TSA Precheck Experience with Delta Airlines
To ensure the smoothest experience, always verify your boarding pass before leaving home. If the TSA Precheck indicator is missing, recheck your Known Traveler Number in your booking. Ensure your identification documents match your reservation exactly. Arrive early at the airport, even though TSA Precheck reduces wait times, because busy travel periods can still result in delays. Keeping your KTN permanently saved in your SkyMiles profile also avoids unnecessary repeated steps. If traveling with family members, remember that children 12 and under automatically accompany eligible adults through TSA Precheck, but older children need their own KTN.
Conclusion
Adding TSA Precheck to your Delta Airlines booking is a simple yet essential step for a faster and more comfortable airport experience. Whether you add your Known Traveler Number through the Delta website, mobile app, or by contacting customer service, ensuring it appears correctly on your boarding pass is the key to accessing expedited security lanes. By saving your KTN in your SkyMiles profile and double-checking your reservation details, you can enjoy a smooth, stress-free journey every time you fly with Delta.
