Cause of Airline Delay and Cancellation Categories Under Section 511(b) of the FAA Reauthorization Act of 2024

Official abstract (Federal Register)

The U.S. Department of Transportation (Department or DOT) is amending its regulations governing how air carriers report the causes of flight cancellations and delays. This action implements Section 511(b) of the FAA Reauthorization Act of 2024, which mandates that ten specific types of events be excluded from the "Air Carrier" causal reporting code. That code is reserved for circumstances that are within the carrier's control. This final rule creates a new reporting category to capture these ten specific events, ensuring that the data reported to the Department and shared with the traveling public accurately reflects the statutory distinction between carrier-controllable events and the specific exclusions identified by Congress.
