The man passed through security in Terminal 8 without being screened at about 4:15 p.m. Saturday, according to the Port Authority of New York and New Jersey.

Passenger screening at the terminal was halted for about 90 minutes while authorities investigated the breach, Port Authority spokesman Joe Pentangelo said.

The breach has caused delays of up to an hour on all American Airlines flights at the terminal.

Authorities had no other information on the man or how he bypassed security.

Kennedy is one of the most heavily trafficked airports in the U.S., handling tens of millions of passengers each year.
