Security lines at airports are surging due to staffing issues stemming from the ongoing partial government shutdown, making TSA PreCheck a lifeline for travelers. While standard security waits can exceed three hours at major hubs like Houston Hobby Airport (HOU), PreCheck members can often get through in under 10 minutes. However, this speed advantage only works if your Known Traveler Number (KTN) is correctly linked to your flight reservation.
The Problem: Missing KTN on Boarding Passes
Many travelers with active PreCheck or Global Entry memberships find that their boarding passes don’t display “TSA PreCheck,” denying them access to expedited lanes. This is a common but easily avoidable issue.
What is a Known Traveler Number?
Your KTN is a series of digits assigned by the U.S. Department of Homeland Security to members of Trusted Traveler Programs like TSA PreCheck and Global Entry. It’s distinct from frequent flyer numbers or confirmation codes. The KTN must be added to either your airline reservation or your profile to ensure it appears on your boarding pass.
How to Find Your KTN
You can locate your KTN in several places:
- Department of Homeland Security portal: Log in to your PreCheck or Global Entry account online.
- Global Entry card: The number is printed directly on your physical card.
- Airline profiles: Check the secure traveler information section within your frequent flyer profile for airlines you’ve used PreCheck with previously.
Adding Your KTN to Reservations
Once found, add your KTN to both your airline profile (for future bookings) and any current reservations through the airline’s website, a kiosk at the airport, or by contacting customer service.
Why This Matters Now
Under normal circumstances, these steps might seem excessive. But with extended security delays and the shutdown continuing, ensuring your KTN is linked could be the difference between catching your flight or missing it. The situation is unlikely to improve quickly, making preparation essential.
The bottom line: In the current climate, verifying and adding your KTN is no longer optional — it’s a practical necessity for smooth travel.
