Federal air marshals are armed, undercover law enforcement officers who fly on commercial passenger flights to detect and neutralise security threats. They operate under the Federal Air Marshal Service (FAMS), a division of the Transportation Security Administration (TSA), which itself falls under the United States Department of Homeland Security (DHS). Their primary mission is to deter hijacking, terrorism, and criminal activity aboard domestic and international flights. They do this entirely in plain clothes, blending in with regular passengers.
The programme dates back to 1961, when President John F. Kennedy ordered armed federal law enforcement officers onto high-risk flights after a wave of hijackings to Cuba. Since then, it has grown from a small team of 18 volunteer inspectors to a classified, multi-thousand-strong force that flies an estimated 181 days a year, spending around 900 hours in the air annually. Today, air marshals are recognised globally as a standard component of layered aviation security, with parallel programmes in Australia, the United Kingdom, Canada, Germany, China, India, and several other countries.
What An Air Marshal Is And Why The Role Exists
An air marshal is a covert federal law enforcement officer deployed on commercial flights to provide in-flight security. The TSA describes the FAMS as the primary law enforcement entity within the agency. Air marshals carry firearms, hold arrest authority, and are trained to respond to hijackings, terrorist acts, and other serious crimes in the confined and pressurised environment of an aircraft cabin.
The need for the role stems from a core vulnerability in commercial aviation: once an aircraft is airborne, ground-based law enforcement cannot intervene. An air marshal closes that gap. Their presence, even when undisclosed to passengers, acts as a deterrent. The uncertainty about which flights carry a marshal is itself a security feature, as potential wrongdoers cannot be certain that a trained agent is not seated next to them.
Air marshals are often referred to as “quiet professionals.” Their effectiveness depends entirely on anonymity. They board flights early, sit in pre-assigned seats chosen for tactical advantage, and observe passengers throughout the journey without revealing their identity unless a threat requires them to act.
A Brief History of the Federal Air Marshal Service
The FAMS was formally established on March 2, 1962, under the Federal Aviation Administration (FAA). Its origins trace to a series of hijackings in 1961, when a man commandeered a National Airlines flight and demanded it land in Cuba. President Kennedy responded by assembling the first 18 volunteer Sky Marshals from the FAA’s Flight Standards Division. They received basic training from the U.S. Border Patrol at Port Isabel, Texas.
The programme expanded in the late 1960s and early 1970s as hijackings surged. At one point, the U.S. Customs Service ran the programme under the name “Sky Marshals.” After mandatory passenger screening was introduced at U.S. airports in 1973, the Customs force was disbanded and the programme shrank to a small group of 10 to 12 FAMs who rarely flew missions.
A second expansion came in 1985 after Hezbollah hijacked TWA Flight 847, brandishing grenades and guns shortly after takeoff from Athens. President Ronald Reagan signed the International Security and Development Cooperation Act, which expanded the statutes supporting the FAMS and extended coverage to international flights. The programme grew to nearly 400 marshals.
The most significant turning point came on September 11, 2001. Only 33 active air marshals were in service on that day, and none were assigned to domestic flights. President George W. Bush signed the Aviation and Transportation Security Act on November 17, 2001, creating the TSA and transferring the FAMS to the new agency. Within one month of the attacks, 600 new marshals were hired and trained. By 2013, the number had grown to an estimated 4,000.
What Air Marshals Do?
Air marshals carry out a range of duties, both in the air and on the ground. Their in-flight responsibilities include:
- Monitoring passengers for signs of suspicious or threatening behaviour
- Deterring and defeating hostile acts, including hijacking attempts and terrorism
- Protecting passengers and crew by intervening when a threat escalates
- Conducting undercover observation throughout the duration of a flight
- Exercising arrest authority and using force when legally required
On the ground, their work extends beyond the aircraft. Air marshals collaborate with FBI Joint Terrorism Task Forces, execute arrest warrants, conduct intelligence-gathering operations, and provide court testimony in national security cases. They also assist with security at major national events. After the September 11 attacks, marshals were deployed on flights near Salt Lake City during the 2002 Winter Olympics and on flights near cities visited by the president.
The TSA reports that a typical air marshal flies approximately 15 days per month, spending around five hours a day airborne. Domestic flights typically carry one or two marshals. Higher-risk international flights may carry up to four.
Flight assignments are not random guesswork. FAMS uses risk-assessment software that analyses factors including aircraft type, departure city, flight path, destination, and fuel load to determine deployment. With approximately 45,000 daily U.S. flights and a force of around 3,000 marshals, only a fraction of all flights carry a marshal at any given time.

Air Marshals Around the World
The United States is not alone in deploying in-flight security officers. Sky marshal programmes operate in numerous countries, with varying names and organisational structures. Israel’s national carrier, El Al Airlines (LY), is widely regarded as operating the most intensive programme, with armed plainclothes guards placed on every flight.
Australia operates an Air Security Officer (ASO) Programme under the Australian Federal Police, introduced in December 2001 following the September 11 attacks. Officers are armed and deployed on both domestic and international flights based on risk intelligence. Austria has operated armed air marshals since 1981 through its Einsatzkommando Cobra unit.
Canada launched its Air Carrier Protection Programme on September 17, 2002, through a memorandum of understanding between the Royal Canadian Mounted Police (RCMP) and Transport Canada. Germany deploys in-flight security officers through the Federal Police. China began placing Aviation Safety Officers on flights in 1973, and in 2004 established a dedicated China Air Marshal Command with over 1,200 sworn officers.
India recruits its sky marshals from the elite National Security Guard (NSG) commando force. The United Kingdom operates a classified programme administered by the Home Office, with details of deployment criteria not publicly disclosed.
Qualifications Required to Become a Federal Air Marshal
The selection process for becoming a Federal Air Marshal is rigorous and multi-staged. Candidates must meet a specific set of baseline requirements before they are considered:
- Be a U.S. citizen
- Be between the ages of 21 and 37 at the time of application
- Hold a valid U.S. driver’s licence
- Be in excellent physical health
A bachelor’s degree from an accredited institution is required for candidates who do not have sufficient qualifying experience. Accepted degree fields include criminal justice, homeland security, law, aviation management, and public administration. Alternatively, three years of progressively responsible work experience in administrative, professional, technical, or investigative roles is accepted in lieu of a degree. A combination of education and experience is also considered.
Candidates must also pass:
- A drug screening test
- A comprehensive criminal and credit background check
- Medical and physical fitness evaluations
- A panel interview and assessment by a supervisory air marshal
- A polygraph examination
- A psychological evaluation
- A top-secret security clearance review
Applications are submitted through the TSA careers portal or the USAJOBS federal employment website. Candidates who advance are invited to take an assessment battery that tests situational judgement, logical reasoning, and written communication skills.
The Air Marshal Training Programme
Candidates who pass all selection stages enter a mandatory 16-week training programme split across two facilities. The first phase consists of 36 days at the Federal Law Enforcement Training Center (FLETC) in Artesia, New Mexico. The second phase takes place at the William J. Hughes Technical Center in Atlantic City, New Jersey, where the FAMS maintains a specialised tactical training facility.
The training curriculum covers:
- Firearms proficiency: 155 hours of lectures and shooting, including the Practice Pistol Course (PPC), which requires firing 60 rounds at targets up to 25 yards away from multiple positions and with both hands
- Aircraft-specific tactics: Movement, positioning, and response protocols inside narrow-body and wide-body aircraft
- Behavioural detection: Identifying pre-attack indicators and anomalous passenger conduct before a threat becomes active
- Close-quarters self-defence: Hand-to-hand combat techniques suited to the confined environment of a passenger cabin
- International law and aircraft medicine: Including first aid procedures that may need to be administered mid-flight
- Criminal and terrorist behaviour recognition: Understanding the patterns and indicators that precede hostile acts
The training facility in Atlantic City includes a 360-degree live-fire shoot house with computer-controlled targets, reflecting the scenario-based nature of FAMS preparation. Recruits are paid throughout training at the entry-level rate.
From 1992 to 2001, the FAMS used the Tactical Pistol Course (TPC), considered one of the most demanding firearms qualifications in global law enforcement. A classified report from the Joint Special Operations Command (JSOC) placed pre-9/11 air marshals among the top one percent of combat shooters in the world. After the rapid post-9/11 expansion, the TPC was replaced with the standard Practice Pistol Course because more than 70 percent of new recruits could not pass the original test under the accelerated hiring timeline.
Air Marshal Salaries And Career Progression
The FAMS uses the TSA’s unique SV pay band system rather than the standard government GS pay scale. Entry-level marshals begin at the SV-G pay band, with a base salary range roughly equivalent to GS-7 to GS-9. Including base pay, locality adjustments, and Law Enforcement Availability Pay (LEAP), a new marshal’s starting total compensation in 2024 was realistically in the $59,000 to $82,000 range, depending on duty location.
With experience, marshals advance to the H and I pay bands, equivalent to GS-11 through GS-13. At these levels, total compensation including LEAP typically ranges from $95,000 to over $150,000. Senior and supervisory marshals in GS-14 and GS-15 equivalent roles can earn in excess of $160,000, particularly in high cost-of-living locations such as New York or Washington D.C. The federal pay cap for senior marshals in 2024 stood at $183,500, in line with Level IV of the Executive Schedule.
Locality pay adds a significant premium. The New York City and Northern New Jersey area attracts an additional 36.16% on top of base pay. Federal benefits include health and dental insurance, retirement through the Federal Employees Retirement System (FERS), and paid leave.
Career advancement paths within FAMS include supervisory field roles, instructor positions at the FAMS Training Center, intelligence analyst positions, and cross-agency assignments with organisations including the FBI and the Department of State.

The Air Marshal and the Broader Aviation Security Architecture
The Federal Air Marshal Service does not operate in isolation. It forms one layer of a multi-tiered aviation security system that also includes TSA checkpoint screening, the Federal Flight Deck Officer (FFDO) programme (which trains volunteer pilots to carry firearms in the cockpit), reinforced cockpit doors mandated after 9/11, and ground-based law enforcement at airports.
The FAMS has also faced scrutiny over the years. A Government Accountability Office (GAO) report released in January 2021 found that while the FAMS had taken steps to assess individual marshal health — including mandatory medical exams — it had not comprehensively evaluated the overall health of its workforce, given the demands of irregular schedules, disrupted sleep, and frequent time-zone changes. The GAO recommended that the FAMS develop a plan to monitor workforce health systematically.
Budget pressures have also shaped the programme. In 2003, FAMS leadership proposed removing marshals from long-haul flights to reduce hotel costs, a plan that was cancelled following congressional objections. The Aviation and Transportation Security Act explicitly requires that long-distance, nonstop flights — the type targeted on September 11 — receive priority in marshal deployment.
Notable Incidents Involving Air Marshals
Active interventions by air marshals have been infrequent, a reflection of the deterrent effect of the programme rather than a lack of vigilance. The most well-documented incident occurred in December 2005, when marshals at Miami International Airport (MIA), Miami shot and killed passenger Rigoberto Alpizar after he ran off a flight claiming to have a bomb in his backpack. Alpizar had a history of mental illness. It was the first shooting by air marshals since the September 11 attacks.
In August 2006, three air marshals took control of a flight from Amsterdam to Mumbai after observing suspicious behaviour among 11 Indian passengers. The aircraft landed safely and the passengers, following investigation, were determined not to pose a threat.
The programme has also drawn criticism unrelated to in-flight conduct. A ProPublica investigation found that between 2002 and 2012, air marshals were arrested 148 times and committed 58 instances of criminal conduct, in addition to over 5,000 minor incidents including missing flights and losing equipment. These findings led to internal reviews and changes in conduct standards.
