The TSA employs roughly 60,000 people across the United States

The Transportation Security Administration has approximately 60,000 employees spread across airports, regional offices, and headquarters. The exact number shifts slightly year to year based on federal budget decisions and staffing needs, but this figure has remained relatively stable for the past decade. The largest group—about 45,000 people—works as Transportation Security Officers (TSOs), the uniformed staff you see at airport checkpoints screening passengers and baggage.

The remaining workforce includes supervisors, federal air marshals, canine handlers, intelligence analysts, administrative staff, and managers. Each role supports the core mission of screening travelers and cargo before they board aircraft. The TSA also employs officers at rail stations, ports, and highways, though the majority of positions are airport-based.

Key Takeaways

  • The TSA employs approximately 60,000 people, with about 45,000 working as Transportation Security Officers at airport checkpoints.
  • The remaining staff includes federal air marshals, supervisors, canine handlers, intelligence analysts, and administrative personnel.
  • Staffing levels vary by airport size and passenger volume, so larger hubs like Atlanta and Los Angeles have significantly more TSA employees than regional airports.
  • TSA employment numbers are set by Congress through annual budget appropriations, which is why staffing can change from year to year.

Where TSA employees work

The vast majority of TSA staff work at commercial airports, stationed at security checkpoints, baggage screening areas, and behind-the-scenes operations. Larger airports like Hartsfield-Jackson Atlanta International, Los Angeles International, and Chicago O'Hare have hundreds of TSA employees each. Smaller regional airports may have only a handful of officers on duty at any given time.

Beyond airports, the TSA maintains a smaller presence at train stations, bus terminals, and maritime ports. The agency also operates a headquarters in Arlington, Virginia, where policy makers, budget analysts, and administrative staff work. Federal air marshals—a specialized unit within the TSA—fly on commercial flights and are stationed at various hub cities across the country.

Transportation Security Officers: the largest job category

Transportation Security Officers make up the bulk of the TSA workforce. These are the employees who operate X-ray machines, conduct pat-downs, check identification, and screen carry-on and checked baggage. TSOs work in shifts to cover early morning, afternoon, and evening flights, and they staff checkpoints seven days a week.

The job requires a high school diploma or equivalent, U.S. citizenship, and the ability to pass a background check and medical screening. TSOs receive on-the-job training after hire and must stay current with security procedures and equipment updates. Staffing levels at each checkpoint are determined by passenger volume and time of day—peak travel hours require more officers than off-peak periods.

Specialized TSA roles beyond checkpoint screening

Federal Air Marshals are armed officers who fly on selected flights to prevent and respond to security threats. The program employs several hundred marshals who work in teams and rotate through different routes. These positions require law enforcement training and firearms certification.

Canine handlers work with dogs trained to detect explosives and other threats. These teams patrol terminals, baggage areas, and sometimes accompany officers to gate areas. Intelligence analysts review security data and threat information to inform TSA operations. Supervisors and managers oversee checkpoint operations, staff scheduling, and compliance with federal security standards. Administrative and support staff handle hiring, payroll, training coordination, and facility management.

How TSA staffing levels are decided

Congress sets the TSA budget each year, and that budget determines how many employees the agency can hire and retain. When Congress increases the TSA appropriation, the agency can hire more officers. When budgets are tight, hiring freezes or attrition (employees leaving without being replaced) can reduce staffing. This is why you may hear news reports about TSA staffing shortages during busy travel periods—the agency is limited by the number of positions Congress has funded.

Individual airports also have staffing plans based on their passenger volume and security risk assessment. A major international hub will have a much larger TSA presence than a small regional airport. The TSA uses historical passenger data and seasonal trends to forecast how many officers each checkpoint needs during different times of year.

Staffing challenges and turnover

The TSA faces ongoing challenges with employee retention. The job involves standing for long shifts, dealing with frustrated travelers, and working holidays and weekends. Pay for entry-level TSOs is modest compared to other federal positions, which contributes to turnover. When officers leave, it takes time to hire and train replacements, which can temporarily reduce checkpoint capacity.

During peak travel seasons—summer vacation, Thanksgiving, Christmas, and spring break—airports often experience longer security lines because staffing cannot always keep pace with passenger surges. The TSA has experimented with hiring bonuses and pay increases to attract and keep officers, but these changes depend on congressional funding.

Regional variations in TSA employment

TSA employment is not evenly distributed across the country. The busiest airports employ hundreds of TSA staff, while smaller airports may have fewer than 20. Atlanta's Hartsfield-Jackson, which handles over 100 million passengers annually, has one of the largest TSA workforces in the nation. By contrast, a regional airport serving 2 to 3 million passengers per year might have 30 to 50 TSA employees total.

Staffing also reflects the type of airport. International hubs require more officers because international passengers undergo additional screening. Airports with significant cargo operations employ officers dedicated to cargo screening. Military installations with civilian air service have TSA staff but may also work alongside military security personnel.

Frequently Asked Questions

Do all TSA employees work at airport checkpoints?

No. While about 45,000 of the 60,000 TSA employees work as Transportation Security Officers at checkpoints, the remaining staff includes federal air marshals, canine handlers, supervisors, intelligence analysts, and administrative personnel. Some work at train stations, ports, and the TSA headquarters in Arlington, Virginia.

Why are security lines sometimes long if the TSA has 60,000 employees?

Staffing is distributed across thousands of airports nationwide, so any single checkpoint may have only a few officers on duty at once. During peak travel times, passenger volume can exceed what the scheduled staff can process quickly. Additionally, not all 60,000 employees work at checkpoints—many work in support roles or at non-airport locations.

How much do TSA employees earn?

Entry-level Transportation Security Officers typically start around $30,000 to $35,000 per year, depending on location and experience. Supervisors and specialized roles earn more. Federal employees also receive benefits like health insurance, retirement plans, and paid leave, which add to total compensation.

Can you become a TSA employee without prior security experience?

Yes. The TSA hires Transportation Security Officers who have a high school diploma or equivalent, U.S. citizenship, and can pass a background check and medical screening. The agency provides on-the-job training after hire. Specialized roles like federal air marshal require law enforcement experience or military background.
