Cause of Airline Delay and Cancellation Categories Under Section 511(b) of the FAA Reauthorization Act of 2024
Key claim: Airlines must stop labeling ten specific delay and cancellation events as the carrier’s fault and instead report them in a new category so public delay statistics match what Congress said is outside an airline’s control.
Abstract
(Rule · Transportation Department) 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.
Why this matters
Public delay and cancellation statistics drive both consumer choice and enforcement priorities at DOT, so how causes are coded materially shapes perceptions of airline reliability. This rule narrows what counts as carrier-caused by carving out ten Congressionally-specified events, without altering any operational or passenger-protection obligation.
