Can I add my known traveler number to an existing reservation?
You can also update existing reservations with your TSA PreCheck number. Go to Edit Traveler Information in the Manage Reservations section on the website, at an airport kiosk or in the United app.

Log into your flight reservation under the Traveler Info section and add your KTN there. You must have been approved for TSA PreCheck before you booked the flight in order for it to be used during a trip.
Most airlines instruct you to log in to your profile and edit your existing reservation in order to add your KTN. For Frontier Airlines, log in to My Trip and have your confirmation code ready. Likewise, you need to go to My Trips to update your existing reservation with Spirit.
How Do I Add My Known Traveler Number to An Airline Reservation? If you received your KTN after booking an existing airline reservation, you may add it at the boarding counter, or at the self-service kiosk at the airport.
Once you add it to your reservation, Expedia processes it just like the airlines would, guaranteeing that your KTN (and, through the transitive property, your Precheck status) shows up on your boarding pass for smooth sailing through TSA. So give it a try!
Yes, you will. I did the same thing a few months ago. My old TSA KTN will expire soon, but for the last 6 months or so, I've had two KTNs (Known Traveler Number). I've used the overlap period to make sure all of my travel accounts are updated with the new number to insure a smooth transition when my old one expires.
Technically your spouse can't go through the TSA PreCheck lane without their own account. In some instances, however, security may allow them through when it's clear that their boarding passes match yours as the primary account holder.
Go to the TSA PreCheck website and select the tab that says “Renewal” to begin the process. Provide your KTN, date of birth and legal last name. You'll then be guided through a series of screens that will ask you to confirm your address and passport information and answer some security questions.
If you still do not have a TSA PreCheck indicator on your boarding pass, please call the TSA Contact Center at (866) 289-9673, submit an online form, or contact us at @AskTSA on Twitter and Facebook Messenger.
Customers will be able to find the pre-notification indicator “TSA PRECHK” on the boarding pass underneath the passenger name field. On mobile boarding passes, the PreCheck logo will appear at the top-right corner above the barcode.
