Thank You for the info. I was also able to add my known traveler #.

All the links to previous responses do not work.  I have added my KTN to my profile for future flights, but I need to add to an existing flight.

Hi!  I'm apparently incompetent and entered in my KTN number incorrectly!  I just got it and was trying to add it to an existing flight.  I tried to repeat the process using the above links, but I can no longer type in my KTN.  It just says "on file."  How can I correct this error?  I already added it to my Southwest account (correctly, I might add).

Hi @Catherine543,

 

We're here to help! Have you checked your reservation to see if the KTN is already entered? It sounds like it might be, and that's why the system isn't giving you the option to enter it.

Hi @tgichikawa,

 

You can fix this pretty easily. You just need to make sure that your KTN is entered, and then re-check in. 

 

Step 1) Visit southwest.com > Click "Flight" in the upper right corner > Manage Reservation > Add Secure Traveler Information

 

Step 2) Check in for your flight on Southwest.com

 

This should remedy the issue!

Lindsey's answer is false!  You can't do it once you've checked in.  You have to call SWA.
