In what year was the Railway Labor Act amended to include airlines engaged in interstate travel?

The Railway Labor Act was amended to include airlines engaged in interstate travel in 1934. This amendment was a significant development in aviation labor relations, as it extended the legal framework that governed labor relations in the railroad industry to the airline industry. The inclusion of airlines under this act meant that the same processes for handling labor disputes, collective bargaining, and the resolution of grievances were applied to airlines, which was crucial as the aviation industry was rapidly growing.

This change reflected the increasing importance of air travel in the nation's transportation infrastructure and recognized the need for uniform labor relations standards across different modes of transportation. The amendment helped ensure more structured and efficient handling of labor negotiations within the aviation sector, ultimately contributing to the development of a more organized labor landscape in airlines.
