In the United States, there are a number of regulations relating to travel and hospitality and the Department of Transportation (DOT) is the U.S. government agency to which Congress has assigned many functions which were formerly performed by the Civil Aeronautics Board. The functions of the Civil Aeronautics Board were transferred to the DOT by the Public Law 98-443 (October 4, 1984) the Sunset Act.
The Department of Transportation initiates and issues the majority of regulations for the travel industry and answers consumer complaints related to travel. Their DOTs duties includes including regulation of: (1) overbooking and denied boarding compensation; (2) liability for lost or damaged baggage; (3) protections on the sale of charters; (4) smoking; (5) discrimination against handicapped persons; (b) computerized reservations systems (CRS); (7) antitrust immunity; (8) unfair competitive practices; and (9) determination of an air carrier's financial and managerial fitness. The DOT has the authority to approve airline mergers and intercarrier agreements under the Federal Aviation Act 408, 409, 412, and 414. The DOT is also responsible for tracking and monitoring airline performance.
