FlyersRights Sues DOT Over Rule That Moves 10 Delay Causes Out of Airline Control

WASHINGTON, D.C., 30 October 2026 – Airline passenger group FlyersRights has filed a petition in the US Court of Appeals for the District of Columbia Circuit challenging a Department of Transportation (DOT) rule on how airlines report the causes of delays and cancellations. The group announced the case, No. 26-1303, in a press release on Friday.

The rule, published on 3 September 2026, creates a new reporting category for 10 types of disruption that Congress said in the FAA Reauthorization Act of 2024 should not be counted as the airline’s fault. FlyersRights says the change shifts the cost of some delays, including mechanical problems, from airlines to passengers.

What the rule changes

Since 2002, the largest US airlines have reported every delay of 15 minutes or more under one of five causes: air carrier, extreme weather, National Aviation System, security or late-arriving aircraft. The “Air Carrier” code covers problems within the airline’s control. The new rule, issued by DOT’s Bureau of Transportation Statistics, moves these 10 events into a new “Section 511(b)” category:

• Cleaning the aircraft after a passenger dies
• Aircraft damage from extreme weather, foreign object debris or sabotage
• Baggage or cargo delays caused by an airport bag system the airline does not control
• Cyberattacks, if the airline follows cybersecurity rules
• An unexpected shutdown or failure of government systems
• Overheated brakes after an emergency
• Unscheduled maintenance, including for an airworthiness directive, that cannot be deferred
• A medical emergency that was not the airline’s fault
• Removing an unruly passenger
• Airport closures due to volcanic ash, wind or wind shear

The rule was due to take effect on 19 October 2026. After a request from the industry group Airlines for America, DOT delayed it to 1 February 2027, so the new categories apply to flights from 1 January 2027.

Why it matters for passengers

The big US airlines promise free meals, hotel rooms and rebooking when a long delay or cancellation is within their control, and some also offer non-cash compensation. In the rule, DOT says that “the total value of amenities and compensation currently provided by air carriers to consumers will be reduced” because the 10 causes will no longer count as airline-controllable. It says it cannot estimate by how much, and it calls this a transfer of value from consumers back to airlines.

DOT’s own case for the rule is that the current data overstates airline-caused delays, which it says harms airlines’ reputations and affects which airline travelers pick. It used the Administrative Procedure Act’s “good cause” exception to skip public comment, saying the 10 exclusions come straight from the law and leave it no discretion.

Part of this is already in place. In December 2025, after an emergency FAA directive forced repairs on some Airbus jets, DOT said it would not treat delays from unscheduled airworthiness-directive maintenance as within airline control for these customer service promises, until the new rule was finished.

What FlyersRights argues

FlyersRights says Section 511(b) lets DOT collect and sort delay data, not change what airlines owe passengers, and that the rule needed public comment. “A change in reporting classifications is not permission to reduce passenger rights,” said Paul Hudson, president of FlyersRights, in the release. The group says it and three other consumer organizations had earlier asked DOT to withdraw the rule.

AeroTime, which reported the lawsuit on 31 October, notes that ticket refund rights are separate from meals, hotels and other assistance and are not affected. Under DOT’s refund rule, passengers are still owed a cash refund if a flight is cancelled or significantly changed and they choose not to travel, whatever the cause; see our US airline refund rules guide.

What happens next

The petition now goes through the DC Circuit, and no hearing date has been announced. Unless the court acts first, the rule takes effect on 1 February 2027. DOT has also said it will write a separate rule, with public comment, on new delay codes for air traffic control and on wider changes that airlines have asked for. FlyingFuel had not seen a public response from DOT to the lawsuit at the time of publishing.
