Cause of Airline Delay and Cancellation Categories Under Section 511(b) of the FAA Reauthorization Act of 2024
What happened
The U.S. Department of Transportation (DOT) is amending its regulations (14 CFR Part 234) for how air carriers report flight cancellation and delay causes. This final rule, signed by Donald Trump, implements Section 511(b) of the FAA Reauthorization Act of 2024, which mandates excluding ten specific events from the 'Air Carrier' reporting code. A new 'Section 511(b) category' is created for these ten events, effective October 19, 2026.
Why it matters
This change ensures that data reported to the DOT and shared with the public more accurately distinguishes between delays airlines can control and those Congress identified as outside their control. The previous 'Air Carrier' category included events now being moved, which could change how airline performance data is perceived.
Who it affects
- ›U.S. air carriers reporting flight delay and cancellation causes.
