After you book a ticket on delta.com, for example, the purchase thank you screen appears and there is link to provide your secure flight data .. but they don't force you to provide it.
I've given it a couple of times until I realized it isn't mandatory at this point.
But this is just my corporate TA. I have no clue if their system is actually transmitting anything. I don't even think it's mandatory to have filled in on their site, but if the agency tells my manager it's not filled in I get in trouble even though it's not mandatory with TSA
