How Do I Add My Known Traveler Number on Delta?

Are you looking to breeze through airport security on your next Delta flight? Adding your Known Traveler Number (KTN) to your Delta account is the key. SIXT.VN understands that international travel, especially to vibrant destinations like Vietnam, should be as smooth as possible. Let’s explore how to add your KTN and enjoy the benefits of TSA PreCheck, ensuring a more relaxed and efficient travel experience with SIXT.VN’s seamless travel solutions. This includes faster security lines and not having to remove shoes or laptops.

1. What is a Known Traveler Number (KTN) and Why Does it Matter?

A Known Traveler Number (KTN) is a unique identifier assigned to individuals approved for trusted traveler programs like TSA PreCheck, Global Entry, NEXUS, or SENTRI. These programs, administered by the U.S. Department of Homeland Security, expedite security screening at airports.

According to the Transportation Security Administration (TSA), TSA PreCheck members experience significantly shorter wait times at airport security checkpoints. Enrolling and adding your KTN to your airline reservations can save you valuable time and reduce stress during your travels.

1.1 Benefits of Using a KTN

• Expedited Security: Access dedicated TSA PreCheck lanes, often resulting in faster processing times.
• Reduced Hassle: No need to remove shoes, belts, or light jackets. You can also leave laptops and compliant liquids in your carry-on bag.
• Convenience: Enjoy a more streamlined and predictable security experience.
• Peace of Mind: Knowing you can navigate airport security quickly and efficiently reduces travel anxiety.

1.2 Who Needs a KTN?

• Frequent Travelers: If you fly multiple times a year, a KTN is a worthwhile investment.
• Travelers Seeking Convenience: Anyone who values a faster, less stressful airport experience.
• Families: TSA PreCheck benefits extend to children aged 12 and under when traveling with an enrolled parent or guardian.
• Business Travelers: Time is money. A KTN helps you stay on schedule.

2. Step-by-Step Guide: Adding Your KTN to Delta Airlines

Adding your KTN to Delta Airlines is a straightforward process that can be done online or through the Fly Delta app. Here’s a detailed guide for both new and existing bookings:

3. Proceed to Passenger Information: After selecting your flights, you’ll be prompted to enter passenger details.

Even after adding your KTN, there are instances where “TSA Pre” may not appear on your boarding pass. Here’s what to do:

3.1 Verify Your Information

• Double-Check Your KTN: Ensure you entered your KTN correctly in your Delta account and reservation. Even a single digit error can prevent TSA PreCheck from appearing on your boarding pass.
• Name Matching: Make sure the name on your airline ticket exactly matches the name you used when applying for TSA PreCheck. Any discrepancies can cause issues.
• Check TSA PreCheck Status: Log in to the TSA website to verify that your TSA PreCheck membership is still active.

3.2 Contact Delta Airlines

If your information is correct and your TSA PreCheck membership is active, contact Delta Airlines customer service. They can investigate why your KTN isn’t being recognized and attempt to resolve the issue.

3.3 Contact TSA

If Delta is unable to resolve the problem, contact TSA directly. They can help troubleshoot technical issues or provide further guidance.

3.4 What If It Still Doesn’t Work?

In some cases, TSA PreCheck may not appear on your boarding pass due to random security checks. Even if you have a KTN, you may occasionally be directed to the standard security lanes.

4. Addressing Common Issues and FAQs

4.1 My KTN Isn’t Working. What Should I Do?

• Verify Accuracy: The most common issue is an incorrectly entered KTN. Double-check every digit.
• Check Expiration Date: TSA PreCheck and other trusted traveler programs have expiration dates. Ensure your membership is current.

Yes, you can add your KTN to an existing reservation through Delta’s website or the Fly Delta app.
