US air passenger rights organization FlyerRights filed a lawsuit against the Department of Transportation on October 30, 2026, challenging a rule that it says could shift the costs of flight disruptions from airlines to passengers. The DOT’s rule revises the categories airlines use when reporting the causes of flight delays and cancellations.
FlyerRights filed its petition with the US Court of Appeals for the District of Columbia Circuit, according to the group’s announcement.
The rule, titled “Cause of Airline Delay and Cancellation Categories under Section 511(b) of the FAA Reauthorization Act of 2024,” amends 4 CFR Part 234 and establishes 10 new categories of delays and cancellations. These categories include unscheduled maintenance and cybersecurity attacks.
The DOT has acknowledged the potential impact of the rule. Airlines currently provide meals, hotel accommodations, and transportation during disruptions within their control. The revised classifications could affect the assistance passengers receive during flight delays and cancellations.
The agency predicts that “the total value of amenities and compensation currently provided by air carriers to consumers will be reduced under this final rule because of the 10 delineated causes of delay and cancellation that will now be excluded from the Air Carrier category in 14 CFR 234.4.”
Consumer Rights Organizations Oppose DOT’s Rule
FlyerRights, along with three other consumer organizations, has previously asked the agency to withdraw the rule. FlyerRights says that the distinction could have consequences for passengers experiencing flight disruptions.
In a group announcement by FlyersRights President Paul Hudson, “A change in reporting classifications is not permission to reduce passenger rights.”
Not the Airline’s Fault?
The maintenance provision of the DOT rule covers unscheduled maintenance that should have been addressed before a flight. This includes maintenance work required by an airworthiness directive.
Other exclusions include delays caused by unruly passengers and medical emergencies. Cybersecurity-related delays also qualify for exclusion only if the airline complies with existing cybersecurity regulations.
The revised reporting requirements will apply to flights beginning January 1, 2027. The DOT said the additional time would allow carriers and the government to update their reporting systems.
