I have received a Known Traveler NumberKnown Traveler Number (KTN) from the TSA but do not know how to "activate" this pre-check authorization with various airlines. Is it possible to get this information into their systems when bookings for flights had preceded receipt of the KTN?

How does one inform airlines of one's KTN, if the KTN was issued after a booking had been made?
