If you fight on a plane, you can face federal criminal charges carrying up to 20 years in prison, FAA civil fines of up to $43,658 per violation, a permanent ban from the airline, loss of TSA PreCheck and Global Entry, a bill from the carrier for a diverted flight, and a personal injury lawsuit from anyone you hurt. All of those tracks can run at the same time from a single incident.
What Happens in the Cabin and at the Gate
Flight attendants are trained to separate and restrain violent passengers. Crews carry plastic flex-cuffs and can direct other passengers to help hold someone down. Once the crew steps in, anything that makes their job harder counts as interfering with a crewmember under federal aviation regulations.
The captain is notified right away and decides whether to divert to the nearest suitable airport. Either way, police meet the aircraft. The FAA refers unruly-passenger incidents to the FBI when warranted, which is common for in-flight violence because the cabin falls under federal jurisdiction.1Federal Aviation Administration. Unruly Passengers Officers typically board before anyone else is allowed off, take statements from the crew and witnesses, and escort those involved for questioning.
Federal Criminal Charges
The interior of a U.S. civil aircraft “in flight” sits within the special aircraft jurisdiction of the United States. That jurisdiction attaches from the moment all external doors close after boarding until a door opens again to let passengers off.2Office of the Law Revision Counsel. 49 US Code 46501 – Definitions Everything in between is federal territory, and two statutes cover most in-flight fights.
Interfering With a Crewmember
If your fight forces a flight attendant to intervene, you can be charged with interfering with a crewmember’s duties. The statute covers assaulting or intimidating any flight crew member or attendant in a way that disrupts or reduces their ability to do their job. Conviction carries up to 20 years in federal prison. If a dangerous weapon is involved, the sentence can be any term of years, including life.3Office of the Law Revision Counsel. 49 US Code 46504 – Interference With Flight Crew Members and Attendants You don’t have to swing at the attendant. Starting a brawl that pulls them away from their safety duties is enough.
Assault on Another Passenger
A separate statute extends federal assault law to acts committed aboard aircraft, including fights between passengers that never involve the crew.4Office of the Law Revision Counsel. 49 US Code 46506 – Application of Certain Criminal Laws to Acts on Aircraft The penalties scale with the harm:
- Simple assault: up to six months in prison and a fine.
- Assault resulting in serious bodily injury: up to 10 years in prison.
- Assault with a dangerous weapon with intent to cause bodily harm: up to 10 years in prison.5Office of the Law Revision Counsel. 18 US Code 113 – Assaults Within Maritime and Territorial Jurisdiction
A fistfight between two passengers who never touch a crewmember still carries federal criminal consequences.
FAA Civil Fines
The FAA runs on a separate track from criminal prosecutors. It has civil authority only, so it cannot send you to prison, but it can fine you whether or not criminal charges are filed.1Federal Aviation Administration. Unruly Passengers Federal regulations explicitly prohibit assaulting, threatening, intimidating, or interfering with any crewmember performing their duties.6eCFR. 14 CFR 91.11 – Prohibition on Interference With Crewmembers
Under its zero-tolerance policy, the FAA can propose fines of up to $43,658 per violation, and one incident often involves several.1Federal Aviation Administration. Unruly Passengers Throwing a punch, refusing to sit down, and swearing at the attendant trying to restrain you can each be charged separately. Because these are civil penalties, there is no public defender and the burden of proof is lower than in criminal court.
Airline Bans and Lost PreCheck
Airlines keep their own internal no-fly lists, and a fight virtually guarantees a ban. Some carriers impose lifetime bans for violent incidents, and affiliated airlines sometimes share these lists, which can effectively lock you out of multiple carriers at once.
Your government travel credentials are also exposed. The Department of Homeland Security has said enforcement against disruptive passengers includes revoking or denying eligibility for TSA PreCheck and other trusted traveler programs like Global Entry.7Transportation Security Administration. Statement by DHS Secretary Alejandro N. Mayorkas Regarding Actions Taken to Combat Threats Posed by Unruly Passengers to Air Transportation Security The FAA confirms that unruly behavior can affect PreCheck eligibility.1Federal Aviation Administration.

Paying for a Diverted Flight
If your fight causes the pilot to divert, the airline will likely come after you for the cost. Industry estimates for a domestic narrow-body diversion run around $15,000 to $20,000, and a wide-body international flight can exceed $100,000.
Federal courts have ordered passengers to pay restitution in these cases, sometimes as part of criminal sentencing. Amounts have ranged from roughly $9,000 for a short domestic diversion to nearly $100,000 for a long-haul international turn-back. The airline doesn’t need a criminal conviction to pursue these costs; it can file a civil lawsuit on its own.
Alcohol Stacks More Violations
Alcohol factors into a large share of in-flight altercations, and the rules around it create extra violations. Federal regulations prohibit airlines from boarding visibly intoxicated passengers, and passengers are not allowed to drink any alcohol on board unless the airline served it to them.8eCFR. 14 CFR 121.575 – Alcoholic Beverages Opening a bottle you brought through security and then getting into a fight adds a regulatory violation to everything else. Being drunk is not a defense to any of the criminal charges above.
Civil Lawsuits From Anyone You Injure
Anyone you injure during a fight, whether a crewmember or another passenger, can sue you for damages. These personal injury claims are separate from criminal prosecution and FAA penalties, so you could face all three at the same time. Injured parties typically seek medical expenses, lost income, and pain and suffering. A crewmember who hurts their back restraining you, or a bystander struck by a stray elbow, has the same right to sue as any assault victim on the ground.
Add up criminal fines, FAA penalties, airline restitution for a diversion, and a personal injury verdict, and total exposure from one in-flight fight can reach six figures before any prison time is counted.
