The Railway Labor Act (RLA) guides contract negotiations in the airline industry in the United States. This act was established by the federal government in 1926 to avoid interruptions in interstate commerce by providing clear instructions for labor unions and railroads and, later, airlines to negotiate labor contracts.

Under the RLA, labor contracts do not expire. Instead, they have amendable dates when the union and the airline agree to discuss specific changes in the ongoing contract. Labor contracts remain in full effect for both parties until a new, amended contract takes effect.

The RLA established the National Mediation Board (NMB) as the federal body charged with overseeing contract negotiations.
