Summary

The head of TSA can put Federal air marshals on passenger flights and must put them on any flights the head says are high security risks. The head must train, supervise, and equip marshals. Airlines must give a marshal a seat on those flights, even if no seats seem available, and at no cost to the marshal or the U.S. Government. Airlines can also be required to give an off-duty marshal a space‑available seat to the airport nearest the marshal’s home at no cost after duty. TSA can make agreements so trained federal, state, or local officers traveling on a flight may carry a firearm and assist marshals. TSA must have procedures to tell marshals about any armed or unarmed law enforcement on board. The agency can hire certain retirees and people furloughed from air carrier crews in the 1‑year period beginning on September 11, 2001, regardless of age, if they meet background and fitness rules. The Federal Air Marshal Service must use a risk‑based strategy to decide how many marshals to place and where, for both domestic and international flights, and must seat marshals in the places best able to meet current threats. Until these rules are fully put in place, the Under Secretary can, with agreement from other agency heads, use personnel from other federal agencies to provide air marshal service without paying those agencies. After consulting the Secretary of State, TSA can train foreign law enforcement, but only after checking their identities against all appropriate federal terrorist watchlist records. The TSA head must set reasonable fees to cover training costs, and money collected goes back to the Treasury account that paid the expenses and is available for the same account purposes.
