SIXT.VN understands the importance of a smooth travel experience, and this guide will walk you through the process of adding your KTN, explaining the benefits, and answering frequently asked questions to ensure your journey in Vietnam is as seamless as possible. Let SIXT.VN help you navigate the world of travel, ensuring a stress-free and enjoyable experience every step of the way with these insider tips.
1. What Is a Known Traveler Number (KTN) and Why Do I Need It?
A Known Traveler Number (KTN) is a unique identification number assigned to individuals who have been pre-approved for expedited security screening programs like TSA PreCheck or Global Entry. According to the Transportation Security Administration (TSA), TSA PreCheck allows eligible travelers to go through security faster at participating U.S. airports. This includes leaving on shoes, light outerwear, and belts, as well as keeping laptops and 3-1-1 compliant liquids in carry-on bags.
1.1. Benefits of Having a KTN
- Expedited Security Screening: The primary benefit is access to faster security lines at the airport.
- Reduced Hassle: You don’t have to remove shoes, belts, or light jackets. You can also leave laptops and compliant liquids in your carry-on.
- Improved Travel Experience: Overall, it makes the airport security process more efficient and less stressful.
- Global Entry Benefits: If your KTN is from Global Entry, you also get expedited entry into the United States upon arrival from international destinations.
1.2. Who Needs a KTN?
- Frequent Flyers: If you travel multiple times a year, the time savings can be significant.
- Families: Traveling with children is easier when you can all go through the PreCheck line together.
- Business Travelers: Time is money, and expedited security can help you make your flights on time.
- International Travelers: Global Entry, which provides a KTN, is invaluable for those frequently entering the U.S. from abroad.
2. How To Add Your Known Traveler Number To Delta After Booking
Adding your KTN to your Delta reservation after booking is straightforward. Here’s a step-by-step guide:
2.1. Step 1: Retrieve Your Booking
- Go to the Delta Website: Navigate to Delta’s official website (https://www.delta.com/).
- Find Your Trip: Look for the “My Trips” or “Find Your Trip” section.
- Enter Confirmation Details: Enter your confirmation number (also known as a record locator), your first name, and your last name. This information can be found on your booking confirmation email.
2.2. Step 2: Access Your Passenger Details
- View Your Reservation: Once you’ve entered your details, click on the button to view your reservation.
- Edit Passenger Information: Look for an option to “Edit Passenger Details” or “Manage Passenger Information”. This might be under a “Modify Flight” or similar section.
2.3. Step 3: Add Your KTN
- Find the KTN Field: Within the passenger details, you should find a field labeled “Known Traveler Number” or “TSA PreCheck/Global Entry Number.”
- Enter Your KTN: Enter your KTN carefully and double-check for accuracy. It’s usually an 8-12 character alphanumeric code.
2.4. Step 4: Save Your Changes
- Save Updates: After entering your KTN, make sure to save the changes you’ve made to your reservation.
- Confirmation: You should receive a confirmation message or email indicating that your KTN has been successfully added.
2.5. Alternative Method: Contact Delta Customer Service
- Call Delta: If you are unable to add your KTN online, you can call Delta’s customer service.
- Provide Booking Information: Provide your booking details and KTN to the agent.
- Confirmation: The agent will add the KTN to your reservation and confirm that it has been updated.
2.6. Adding KTN via Delta App
- Open the App: Open the Delta Airlines app on your smartphone or tablet.
- Go to My Trips: Find and tap on the “My Trips” section.

3. What If I Forget To Add My KTN Before Flying?
Forgetting to add your KTN before your flight can be frustrating, but here’s what you can do:
3.1. Add at the Airport
- Check-In Kiosk: Some airport check-in kiosks allow you to add your KTN at the time of check-in.
- Check-In Counter: If the kiosk doesn’t allow it, ask the Delta agent at the check-in counter to add it.
3.2. Possible Outcomes
- Success: If added successfully, your boarding pass will be marked with the TSA PreCheck indicator.
- No Guarantee: Adding your KTN at the last minute doesn’t guarantee TSA PreCheck access. The TSA uses unpredictable risk-based assessment, and sometimes even with a KTN, you may be directed to the standard security line.
3.3. Future Prevention
- Update Your Delta Profile: To prevent this in the future, update your Delta SkyMiles profile with your KTN. This way, it will automatically be added to all future reservations.
4. Troubleshooting Common Issues When Adding Your KTN
Sometimes, adding your KTN doesn’t go as smoothly as planned. Here are some common issues and how to resolve them:
4.1. KTN Not Recognized
- Check Accuracy: Ensure you’ve entered your KTN correctly. Even a small typo can cause it to be rejected.
- KTN Expiration: Verify that your TSA PreCheck or Global Entry membership hasn’t expired.
- System Delay: Sometimes, there may be a delay in the system updating. Try again later or contact Delta customer service.
4.2. Name Mismatch
- Name Consistency: The name on your airline ticket must exactly match the name on your TSA PreCheck or Global Entry application.
- Update Information: If your name has changed due to marriage or other reasons, update it with both the TSA and Delta.
4.3. Technical Issues
- Website/App Problems: If you’re having trouble adding your KTN online, try using a different browser or device.
- Clear Cache: Clear your browser’s cache and cookies, or try using a private browsing window.
4.4. Contacting Delta for Support
- Customer Service: If you’ve tried the above steps and are still having issues, contact Delta customer service for assistance.
- Provide Details: Be ready to provide your booking details and KTN to the agent.
