A new U.S. Department of Transportation rule will take effect on October 19, 2026, reclassifying 10 specific events as outside an airline's control for the purposes of flight delay and cancellation reporting.

The change amends 14 CFR 234.4, the regulation governing how carriers classify the causes of disruptions, and was mandated by the FAA Reauthorization Act of 2024.

Under the rule, airlines will not be held responsible for circumstances including aircraft damage from extreme weather or foreign object debris, cybersecurity attacks, unscheduled maintenance, the removal of unruly passengers, and airport closures caused by volcanic ash, wind, or wind shear.

The DOT said the change is a "transfer of value from consumers back to air carriers," and passengers may receive reduced compensation, such as meal or hotel vouchers, for disruptions covered by the new categories.
