Individuals employed as ramp workers who frequently handle cargo for an airline are "transportation workers" exempt from the Federal Arbitration Act (FAA), the U.S. Supreme Court has held.

Therefore, the employees are not required to arbitrate their wage-hour claims under the FAA, but may still be subject to arbitration under state law. The FAA's transportation worker exception excludes from FAA coverage "contracts of employment of seamen, railroad employees, or any other class of workers engaged in foreign or interstate commerce." 9 U.S.C. § 1. In recent years, the scope of the exception — particularly its "any other class of workers" catchall provision — has emerged as a significant issue in class action litigation.
