Steps to Add Your Known Traveler Number Across Airlines

Locate Your Known Traveler Number (KTN)
Log in to your Trusted Traveler account. Find your 9-digit KTN on the dashboard.
The KTN is listed on your Global Entry, PreCheck, NEXUS, or SENTRI dashboard. Copy it carefully—letter/number confusion is common.
Sign Into Each Airline Profile
Access every major airline’s frequent flyer account you use.
Go to the official airline website or app and sign in. Don't forget partner and smaller carriers if you fly them occasionally.
Update Personal Information
Navigate to your profile or traveler information section.
Most systems list KTN under Profile, Security, Travel Documents, or Traveler Info. Look for a field labeled 'Known Traveler Number,' 'Trusted Traveler Number,' or 'PASS ID.'
Paste and Save Your KTN
Enter your KTN exactly as shown in your TTP account.
Check for case sensitivity, automatic spaces, and accidental typos. Ensure your name in the airline profile matches your TTP account.
Confirm Existing and New Reservations
Double-check that your KTN now appears on all future bookings.
For older bookings, manual addition to each reservation might be necessary.

| Method | Profile Entry | Per-Reservation Entry |
|---|---|---|
