Airline Delay Rule Due to Start Today Is Pushed to February 2027

WASHINGTON. A federal rule that was due to change how airlines explain delays and cancellations on Monday will not take effect until February 1, 2027. The Transportation Department pushed back its October 19 start date.

The rule carries out a section of the FAA Reauthorization Act of 2024, in which Congress told the department to stop counting 10 kinds of flight disruption as the airline's fault. Those causes move out of the Air Carrier category, which covers problems within an airline's control, and into a new reporting category created by the law. Airlines report delay and cancellation causes to the Bureau of Transportation Statistics.

Why the start moved

The department published the final rule on September 3 and set October 19 as the start. On September 21, Airlines for America, the big carriers' trade group, asked for a delay to February 1, 2027. The group said the bureau and the carriers needed time to update their reporting systems, and the department needed approval for the revised information collection under the Paperwork Reduction Act. The department agreed. In a notice published in the Federal Register on October 15, it said applying the change to flights from January 1, 2027 would give clearer information for consumers and the industry. January flights will be the first reported under the new categories.

The 10 causes that move

The reclassified causes are unscheduled maintenance that cannot be deferred or must be fixed before flight, including work ordered by an airworthiness directive; removal of an unruly passenger; a medical emergency that was not the carrier's fault; cleaning an aircraft after the death of a passenger; damage from extreme weather, foreign object debris or sabotage; a cyberattack, if the carrier follows federal cybersecurity rules; an unexpected shutdown or failure of government systems that affects safe flying; a baggage or cargo delay from an outage in a bag system the carrier does not control; overheated brakes after a safety incident that required emergency procedures; and an airport closure caused by volcanic ash, wind or wind shear.

What it means for passengers

Airlines promise meals, hotel rooms and ground transport in their customer service plans for disruptions within their control, and the department can hold them to those promises. A delay sorted into the new category may no longer trigger that help. In the September rule, the department said the number of delays and cancellations for which carriers provide amenities and compensation is expected to fall, and it described the value of the lost vouchers and rooms as a transfer from consumers back to carriers. It also said it could not estimate the size of that transfer.

"This is going to impact passengers in a very direct way," William J. McGee, a senior fellow for aviation and travel at the American Economic Liberties Project, told USA Today. "You're going to be given fewer rights in terms of compensation through meals, hotels and things like that."

Erika Josefsson, an air passenger rights expert at AirHelp, told USA Today the biggest effect is likely to come from unscheduled maintenance. She advises passengers to ask why a flight was delayed, keep the airline's notifications, and check each carrier's promises on the department's delay dashboard. Airlines can still offer help voluntarily after February 2027.

One protection does not change. A separate 2024 rule still gives passengers a refund when a flight is canceled or significantly changed and they decline to travel. For anyone flying today, the old definitions still apply, and they will keep applying through the holiday season.
