On May 31, during Frontier Airlines Flight 3345 from San Juan, Puerto Rico, to Chicago, former MMA fighter Josh Longood intervened when a fellow passenger attempted to open an emergency exit door and assaulted a flight attendant. Longood, a Brazilian jiu-jitsu black belt, noticed the passenger behaving erratically and sprang into action when the situation escalated. He managed to restrain the man for approximately 10 minutes before the passenger broke free, prompting Longood to re-secure him for another 20 to 30 minutes until the flight was diverted to Miami for an emergency landing. A Frontier spokesperson confirmed the incident, stating that law enforcement boarded the aircraft in Miami to remove the disruptive individual. Longood expressed gratitude for being in a position to help and emphasized his confidence in handling such situations due to his martial arts training. He reassured that he would not hesitate to intervene again if necessary. Additionally, it was noted that modern aircraft doors are designed to prevent opening at cruising altitude, ensuring passenger safety.
