So, a little help here.
I got the e-mails from DL when they first sent them out but never responded to them - yeah, my stupidity. Deleted the e-mails and I keep a pretty clean deleted folder so I don't have access to any of the e-mails.
What did I need to do to sign up to start using pre-check, other than keeping my secure flight passenger data updated and allowing DL to share the data with tsa?
I heard somebody say that after registering / responding to the initial e-mail that DL sent out that you got a phone call from somebody at TSA who asked you a bunch of questions, etc to get "approved".
thanks
