Several outlets report that an American Airlines flight approaching Philadelphia Sunday experiences onboard disruption after a passenger allegedly bites another traveler. CBS News says the incident is described in reports from the flight crew on a flight from Charlotte to Philadelphia. According to the pilot’s account, the passenger becomes dangerously disruptive, including biting a fellow passenger and acting aggressively toward others aboard. The pilot also reports statements in radio transmissions indicating the person was “trying to fight everybody.” American Airlines characterizes the situation as involving a medical emergency, and the airline’s statement is reflected in the coverage.

The New York Post and Mint also describe the mid-air chaos based on the pilot’s reported communications. Across the reports, the central points are that a passenger bites another traveler, the crew describes escalating aggression, and the airline attributes the incident to a medical emergency.
