I take it in days past, you would pick up a ticket at the travel agent and get a BP at the counter?

I've never flown without getting a BP. I'm flying AC for the first time in 10 years so I don't know the procedures?

Am I stressing about nothing? Also, at a very small airport where I'm flying out of, is there a security checkpoint? Or do I just walk in, get my BP and get on the plane?

BTW, I reviewed the times on the e-ticket. They are identical to prior notices. I think I got the email as a courtesy.
