Traveling can be hectic, especially when navigating long airport security lines. Fortunately, if you're a member of TSA PreCheck, you can breeze through designated security lanes without removing your shoes, belt, light jacket, laptop, or liquids. If you’re flying with Delta Air Lines, it’s important to ensure your TSA PreCheck status is correctly attached to your booking. In this comprehensive guide, you’ll learn how to add TSA PreCheck to your Delta Airlines reservation, whether you’re booking a new ticket or updating an existing one.


What Is TSA PreCheck?

TSA PreCheck is a U.S. government-run program designed to speed up airport security for low-risk travelers. Once approved, you’ll receive a Known Traveler Number (KTN), which must be included in your airline profile or booking to access the expedited lanes at over 200 U.S. airports.

TSA PreCheck is valid for five years and is accepted by more than 85 airlines, including Delta.


Step 1: Enroll in TSA PreCheck

If you haven't enrolled yet, you need to start here. The process is straightforward and typically quick.

How to Apply:

  1. Online Application: Visit www.tsa.gov/precheck and fill out the online form.

  2. In-Person Appointment: Schedule and attend an appointment at a nearby enrollment center.

  3. Provide ID and Fingerprints: Bring valid government-issued ID, submit fingerprints, and answer a few background questions.

  4. Fee: Pay the $78 application fee (valid for 5 years).

  5. Receive KTN: After approval, you’ll receive your Known Traveler Number by mail or email.


Step 2: Add Your KTN to Your Delta Profile or Booking

Once you have your KTN, you need to make sure it’s added to your Delta reservation or SkyMiles profile. Here are all the ways to do that:


Option A: Add KTN While Booking a New Flight

If you're booking a new flight on delta.com or via the Fly Delta app, follow these steps:

  1. Go to www.delta.com and begin the flight booking process.

  2. During the passenger information section, look for the field labeled “Known Traveler Number.”

  3. Enter your KTN exactly as it appears in your TSA PreCheck approval.

  4. Complete the booking.

This ensures that your PreCheck information is linked to your ticket from the start.


Option B: Add KTN to an Existing Delta Reservation

If you’ve already booked a Delta flight, don’t worry—you can still update your reservation to include your KTN.

Via Website:

  1. Visit www.delta.com and click on “My Trips.”

  2. Log in using your SkyMiles number or enter your confirmation number and last name.

  3. Select the reservation you'd like to update.

  4. Click "Add/Edit Passenger Information."

  5. Input your KTN in the designated field and save the changes.

Via Mobile App:

  1. Open the Fly Delta app.

  2. Tap on “Trips” and select your flight.

  3. Scroll to find “Passenger Info” or “Edit traveler details.”

  4. Enter your KTN and save.


Option C: Add KTN to Your SkyMiles Profile (For All Future Bookings)

To save time on future bookings, add your KTN to your Delta SkyMiles profile:

  1. Log into your SkyMiles account at www.delta.com.

  2. Click on “My Profile” under your account.

  3. Navigate to the Basic Info or Secure Flight section.

  4. Enter your Known Traveler Number in the correct field.

  5. Click “Save.”

Now, every flight you book while logged in to your account will automatically include your TSA PreCheck eligibility.


Step 3: Verify That TSA PreCheck Is Applied

Once you’ve added your KTN, always check your boarding pass to confirm that TSA PreCheck is activated.

You should see a “TSA Pre✓” indicator on your boarding pass (digital or printed). If it doesn’t appear:

  • Double-check that the name on your ticket exactly matches the name used during TSA PreCheck enrollment.

  • Ensure the KTN was entered correctly.

  • Contact Delta’s customer service for help: +1‑833‑341‑3894


Benefits of TSA PreCheck on Delta

Here’s why adding TSA PreCheck to your Delta booking is worth the effort:

  • Dedicated PreCheck security lanes at most U.S. airports.

  • No need to remove shoes, belts, light jackets, laptops, or compliant liquids.

  • Shorter wait times, especially during peak hours.

  • More predictable and stress-free airport experience.


Troubleshooting: Common Issues and Fixes

KTN Not Showing on Boarding Pass?

  • Check spelling: Your name on the ticket must match your TSA PreCheck registration exactly.

  • Late updates: Make sure you enter your KTN at least 72 hours before your flight.

  • Wrong booking portal: If you booked through a third-party site, you might need to call Delta to manually add your KTN.

Still No PreCheck Access?


Tips for Using TSA PreCheck with Delta

  • Check-in early: Even with PreCheck, arrive at least 90 minutes before your flight.

  • Children 12 and under traveling with you are automatically allowed through PreCheck lanes.

  • Combine with CLEAR: For an even faster airport experience, Delta partners with CLEAR, which can be used alongside TSA PreCheck.
