As directed by the Aviation and Transportation Security Act, the major responsibilities of airline passenger and baggage screening is now handled by our agency. To assist in paying for the increased aviation security, Congress provided us with the authority to charge airlines a fee equal to their costs of passenger and baggage screening in 2000, to the extent that the September 11 Security Fee was insufficient to cover the agency's costs for aviation security. Airlines pay one-twelfth per month of their 2000 screening costs to TSA.
