An angry passenger used his mother's old Air France employee documents to con his way into the cockpit of a US Airways flight last week, according to the criminal complaint filed against him Monday in U.S District Court in Philadelphia.

Philippe Jeannard, 61, had become disruptive Wednesday after being told that the airline could not accommodate his request to move up to business class during a stopover in Philadelphia. FBI Special Agent Brian L. Jones described Jeannard in an affidavit as difficult and verbally abusive to a flight attendant and gate supervisor.

Jeannard was wearing a white button-down shirt with an Air France logo over the pocket and a black jacket with four gold stripes on the epaulets, similar to one worn by pilots, the complaint said. He identified himself to the gate supervisor as an Air France pilot.
