A federal air marshal is an armed, plainclothes federal law enforcement officer who flies undercover on commercial flights to stop hijackings, attacks, and other serious crimes in the air. Air marshals work for the Transportation Security Administration’s Law Enforcement/Federal Air Marshal Service within the Department of Homeland Security, and their job extends beyond the cabin to ground investigations, task force work, and transportation security operations.1Transportation Security Administration. Law Enforcement The total number of marshals and the flights they cover are classified.
What Air Marshals Do on a Flight
The core of the job is blending in. Marshals board like any other passenger, dress in plain clothes, and sit in assigned seats chosen for tactical advantage. During the flight they watch for signs of criminal or hostile behavior, quietly assess the cabin, and stay ready to act. If a threat develops, they’re trained in close-quarters self-defense and, when necessary, firearms use inside the confined space of an aircraft cabin.2Transportation Security Administration.

One federal crime marshals are positioned to address is interference with flight crew. Anyone on an aircraft who assaults or intimidates a crew member in a way that disrupts that person’s duties faces up to 20 years in prison, and if a dangerous weapon is involved, the sentence can be life.3Office of the Law Revision Counsel. 49 USC 46504 – Interference With Flight Crew Members and Attendants A marshal who witnesses that conduct can arrest the passenger on the spot, without waiting for local police at the destination.
Air marshals don’t ride every flight. Federal law requires TSA to deploy them on every flight the agency determines to present a high security risk and permits deployment on any other passenger flight. Selection is intelligence-driven and risk-based, and airlines must provide a seat to a marshal on any covered flight at no cost to the government.4Office of the Law Revision Counsel. 49 USC 44917 – Deployment of Federal Air Marshals
What Air Marshals Do on the Ground
A significant portion of the work happens at ground level. Air marshals are assigned to FBI Joint Terrorism Task Forces across the country, where they collaborate with federal, state, and local investigators on terrorism-related cases. They also conduct their own investigations into suspicious aviation-related activity, execute arrest warrants, and testify in court.2Transportation Security Administration.

Marshals also work on Visible Intermodal Prevention and Response teams. Federal law authorizes TSA to build these teams using assets from across DHS, including air marshals, canine units, and screening technology, and deploy them at airports, train stations, bus terminals, and other transportation hubs, usually around major events or during periods of elevated threat.5Office of the Law Revision Counsel. 6 USC 1112 – Authorization of Visible Intermodal Prevention and Response Teams
Legal Authority
Arrest and Firearms
Federal law gives TSA’s Administrator authority to let air transportation security personnel carry firearms and make warrantless arrests for any federal offense committed in their presence, or for any federal felony when the officer reasonably believes the person has committed or is committing that felony.6Office of the Law Revision Counsel. 49 USC 44903 – Air Transportation Security That is a broad grant. A marshal who sees a passenger physically attacking a flight attendant can arrest that person immediately.
Use of Force
Air marshals, like all DHS law enforcement officers, are governed by DHS Policy Statement 044-05. The standard is “objective reasonableness”: force must be reasonable given the totality of what the officer is facing at the time. Deadly force is permitted only when the officer reasonably believes the subject poses an imminent threat of death or serious bodily injury to the officer or someone else, and the policy specifically prohibits using deadly force solely to prevent someone from fleeing unless that person also poses a significant threat of death or serious harm to others.7Department of Homeland Security. DHS Policy Statement 044-05 – Department Policy on the Use of Force
Carrying Off Duty
TSA encourages marshals to carry a TSA-authorized firearm even off duty, because they can be recalled at any time. They also qualify under the Law Enforcement Officers Safety Act, which allows qualified federal officers to carry a concealed firearm in any state regardless of that state’s own concealed-carry laws, as long as they carry their agency-issued photo identification and regularly qualify on their firearm.8Office of the Law Revision Counsel. 18 USC 926B – Carrying of Concealed Firearms by Qualified Law Enforcement Officers
How to Become an Air Marshal
Applicants must be U.S. citizens between 21 and 36 years old with a valid driver’s license. Veterans over 36 may qualify for an age exception, and the deployment statute separately permits TSA to appoint retired law enforcement officers and retired military members regardless of age.4Office of the Law Revision Counsel. 49 USC 44917 – Deployment of Federal Air Marshals Candidates must also pass a Physical Efficiency Battery testing endurance, strength, and agility, and they must hold a top-secret security clearance as a condition of employment.9U.S. Secret Service. Special Agent Recruitment Information for Federal Air Marshals
Training is a multi-phase pipeline widely considered one of the most demanding in federal law enforcement. New hires start at the Federal Law Enforcement Training Centers campus in Artesia, New Mexico, for basic law enforcement instruction, then move to the Federal Air Marshal Service Training Center near Atlantic City International Airport for aircraft tactics, behavior recognition, and close-quarters combat scenarios inside a pressurized cabin.10Federal Law Enforcement Training Centers.

FLETA Reaccredits the Federal Air Marshal Service Training Center and Training Program II
Firearms training is intense. According to TSA’s pre-training guide, trainees fire roughly 5,800 rounds with their issued semiautomatic pistol over approximately 155 hours of firearms instruction and must qualify on the Federal Air Marshal Service Practical Pistol Course before graduating.12Transportation Security Administration. Pre-Training Guide Federal Air Marshal Service The volume reflects the difficulty of accurate fire inside an aircraft cabin, where a miss can puncture the fuselage or hit a passenger.
Pay
Air marshals are paid under TSA’s SV pay-band system rather than the General Schedule that covers most federal employees. Entry-level positions typically start at Pay Band G. On top of base salary, marshals receive locality pay that varies by duty station and Law Enforcement Availability Pay, a supplement for officers expected to work unscheduled duty hours on short notice. Combined, base pay, locality adjustments, and availability pay make actual take-home meaningfully higher than the base band alone.1Transportation Security Administration. Law Enforcement
Filing a Complaint Against an Air Marshal
Because marshals operate with significant authority and minimal public visibility, complaints go through the DHS Office of Inspector General. Passengers, fellow officers, and airline employees can file through the DHS OIG Hotline online or by phone. The form allows anonymous complaints, though the OIG warns anonymity can limit its ability to investigate. Complainants who identify themselves can also request that their identity be kept confidential.13Department of Homeland Security Office of Inspector General. DHS OIG Hotline Complaint Form Internally, every use of force must be documented and reviewed against the objective-reasonableness standard.
