Yes, 1996. The ID check was not at the security checkpoint but at the check-in counter, where most passengers would exchange a paper ticket (the first e-tickets rolled out in 1994 or 1995, but the vast majority of tickets were still paper in 1996) for a paper boarding pass and need to show ID as part of that process.
