Discover how to effortlessly add your trusted traveler information and unlock faster security lines, enhancing your overall travel experience. Improve your air travel convenience with these simple steps, ensuring your next flight is as stress-free as possible.

1. Understanding the Known Traveler Number (KTN)

A Known Traveler Number (KTN) is a unique identifier assigned to individuals who have been pre-approved for expedited security screening programs like TSA PreCheck or Global Entry. These programs are designed to enhance airport security while making travel more efficient for low-risk passengers. According to the Transportation Security Administration (TSA), passengers with a KTN often experience shorter wait times and a more streamlined screening process at airport security checkpoints.

1.1. Benefits of Having a KTN

Having a KTN provides several advantages, primarily centered around expedited security screening. Here’s a detailed look at the benefits:

Expedited Security Screening: Passengers with a KTN can use dedicated TSA PreCheck lanes, which typically have shorter wait times.
Reduced Screening Requirements: TSA PreCheck passengers often don’t need to remove shoes, belts, or light jackets. Additionally, laptops and compliant liquids can remain in carry-on bags.
Faster Processing: The overall security process is faster, allowing you to get to your gate more quickly.
Increased Convenience: Streamlined security procedures make the pre-flight experience more convenient and less stressful.

1.2. Who Needs a KTN?

A KTN is beneficial for frequent travelers, business professionals, and anyone who values time and convenience at the airport. Here are the primary groups who should consider obtaining a KTN:

Frequent Flyers: If you travel multiple times a year, the time savings from expedited screening can add up significantly.
Business Travelers: Time is often of the essence for business travelers, making the faster security process highly valuable.
Families: Traveling with children can be challenging, and expedited screening can help make the airport experience smoother for families.
Individuals Seeking Convenience: Anyone who wants to reduce stress and save time at the airport can benefit from having a KTN.

1.3. TSA PreCheck vs. Global Entry: Which is Right for You?

Both TSA PreCheck and Global Entry provide a KTN, but they cater to different travel needs. Here’s a comparison to help you decide which program is right for you:

Feature	TSA PreCheck	Global Entry
Primary Benefit	Expedited security screening for domestic flights.	Expedited customs and immigration processing for international travel, plus TSA PreCheck benefits.
Eligibility	U.S. citizens, U.S. nationals, and lawful permanent residents.	U.S. citizens, U.S. nationals, lawful permanent residents, and citizens of certain other countries.
Application Process	Online application and in-person enrollment, including fingerprinting.	Online application and in-person interview, including fingerprinting.
Cost	$85 for a five-year membership.	$100 for a five-year membership.
Use Cases	Ideal for those who primarily travel domestically and want to expedite security screening within the U.S.	Best for those who travel internationally frequently and want to expedite both security screening within the U.S. and customs/immigration processing upon re-entry.
Additional Benefits	Access to TSA PreCheck lanes at participating airports.	Includes TSA PreCheck benefits, plus expedited entry into the U.S. through automated kiosks at airports.
Renewal	Online renewal available.	Online renewal available.
Website	TSA PreCheck Official Website	Global Entry Official Website

Choosing between TSA PreCheck and Global Entry depends on your travel patterns. If you mainly fly within the U.S., TSA PreCheck is likely the better option. If you frequently travel internationally, Global Entry offers more comprehensive benefits, including TSA PreCheck.

2. Finding Your Known Traveler Number

Before you can add your KTN to your United Airlines reservation, you need to locate it. Your KTN is typically provided by the program you enrolled in, such as TSA PreCheck or Global Entry.

Check Your TSA PreCheck Card: Your KTN is printed on the front of your TSA PreCheck card.
Review Your Approval Email: When you were approved for TSA PreCheck, you should have received an email containing your KTN. Search your email inbox for messages from the TSA or the Department of Homeland Security.

Log into Your Trusted Traveler Program (TTP) Account: You can log into your TTP account on the Department of Homeland Security website to view your PASSID.
