TSA Precheck

Hello!

 

I just got approved for TSA Pre and got a KTN but I already have booked 3 trips couple weeks ago. Will the KTN work on these flight although I didn't provide a KTN number when booking? or the KTN will work from this day one?

 

Thanks,

First, add your KTN to your Southwest profile. This should allow it to automatically populate whenever you make a new reservation.

 

Then, add it manually if necessary to each existing reservation.

Thank you for the reply, but how can you add the KTN number to an existing flight?
