How Do I Add My Known Traveler Number to Delta Flight?

Adding your Known Traveler Number (KTN) to your Delta flight ensures a smoother and faster airport security experience through TSA PreCheck. This allows eligible travelers to enjoy expedited screening lanes. TRAVELS.EDU.VN guides you through the simple steps of adding your KTN, ensuring you benefit from quicker security checks and a more relaxed travel experience. You’ll get through the airport faster, keeping your trusted traveler programs like Global Entry benefits.

1. What is a Known Traveler Number and Why Do I Need It for Delta Flights?

A Known Traveler Number (KTN) is a unique identifier assigned to individuals who have been approved for trusted traveler programs like TSA PreCheck, Global Entry, NEXUS, or SENTRI. This number verifies your eligibility for expedited security screening at airports. By adding your KTN to your Delta flight reservation, you ensure that the TSA PreCheck indicator appears on your boarding pass, granting you access to the faster security lanes.

1.1 What Are the Benefits of Adding a KTN?

Adding your KTN to your Delta flight comes with several benefits:

Expedited Security Screening: Access to TSA PreCheck lanes, which typically have shorter wait times.
No Need to Remove Shoes, Belts, or Light Outerwear: Streamlined screening process allowing you to keep these items on.
Laptop and Liquids Stay in Your Bag: No need to remove these items from your carry-on luggage.
Faster Overall Airport Experience: Reduced time spent in security lines, making your journey more efficient.

1.2 Trusted Traveler Programs: Which One is Right for You?

Several trusted traveler programs offer a KTN, each catering to different travel needs:

TSA PreCheck: Ideal for frequent domestic travelers. It costs $85 and is valid for five years.
Global Entry: Best for international travelers. It includes TSA PreCheck benefits and costs $100, valid for five years.
NEXUS: Designed for travelers between the U.S. and Canada. It costs $50 and is valid for five years.
SENTRI: For frequent travelers entering the U.S. from Mexico. The cost is $122.25, valid for five years.

The right program depends on your travel frequency and destinations. According to the U.S. Department of Homeland Security, Global Entry members spend significantly less time in customs lines, making it a popular choice for international travelers.
