From February 1, 2027, the US Department of Transportation will stop counting 10 types of flight disruption as within an airline's control. The change will not remove the refund right for a canceled flight, but it will narrow the meal and hotel help that airlines promise when they cause a delay.
Congress directed the change in the FAA Reauthorization Act of 2024. Section 511(b) told the Transportation Department to exclude 10 specific events from the Air Carrier causal code, the code used in government delay and cancellation reporting for circumstances within a carrier's control. The department published a final rule on September 3, 2026, to carry out that direction, and it created a new reporting category for the 10 events.
The rule was first set to take effect on October 19, 2026. Airlines for America asked on September 21 for more time to update reporting systems, and the department agreed in a Federal Register notice on October 15 to delay the effective date to February 1, 2027. The department said applying the new reporting categories to flights starting with the new calendar year would give clearer information for consumers and industry.
A delay in January will be reported under the new categories, even though the delayed effective date is in February.
The 10 disruptions
- Aircraft cleaning necessitated by the death of a passenger.
- Aircraft damage caused by extreme weather, foreign object debris, or sabotage.
- A baggage or cargo loading delay caused by an outage of a bag system not controlled by a carrier or its contractor.
- Cybersecurity attacks, provided that the air carrier is in compliance with applicable cybersecurity regulations.
- A shutdown or system failure of government systems that directly affects the ability of an air carrier to conduct flights safely and is unexpected.
- Overheated brakes due to a safety incident resulting in the use of emergency procedures.
- Unscheduled maintenance, including work in response to an airworthiness directive, manifesting outside a scheduled maintenance program that cannot be deferred or must be addressed before flight.
- An emergency that required medical attention through no fault of the carrier.
- The removal of an unruly passenger.
- An airport closure due to the presence of volcanic ash, wind, or wind shear.
The maintenance item is the one most likely to surprise a passenger at the gate. A broken airplane looks like an airline problem, and in many cases it still is. Scheduled maintenance, crew scheduling, and routine cleaning or restocking remain airline responsibilities. The new category covers only unscheduled work outside a scheduled maintenance program that cannot be deferred. If a defect could have been deferred under an acceptable deferred defect process, the delay should still count as carrier controlled. That distinction will matter when a passenger disputes a denied voucher, because the airline's own record of whether the work could wait becomes part of the argument.
What stays the same
Refunds are separate from meal and hotel promises. If an airline cancels a flight or makes a significant change and a passenger declines the alternative offered, the passenger is still entitled to a refund for the unused ticket. For a domestic flight, a significant change includes departing three or more hours earlier than scheduled or arriving three or more hours later. For an international flight, the threshold is six hours.
Meal and hotel help in the United States is not a cash compensation law like the system in Europe. It comes from customer service plans that airlines file with the Transportation Department and that the department can enforce. The department's Airline Cancellation and Delay Dashboard lists what each airline promises for controllable cancellations and delays. All 10 large airlines listed there promise a meal or meal voucher after a controllable delay of three hours or more. Nine promise a hotel for an overnight controllable delay. Frontier is the exception on the hotel promise.
Under the new categories, those promises will apply to fewer delays. The department said in its rulemaking that the total value of amenities and compensation provided by air carriers to consumers is expected to fall. The department also said the change would ensure government delay data accurately reflects what airlines can and cannot control.
Disruptions coded under Section 511(b) will also no longer show up as airline caused in Bureau of Transportation Statistics data. An airline's reported controllable delay figure can therefore improve without any change in how often its flights actually run late. Readers comparing figures from before and after January should check which code was used, not only the headline rate.
What to do at the airport
Ask the airline for the stated reason for a delay and keep a record of it. Request the explanation in writing, or take a screenshot of the airline app notification at the time. Save receipts for meals, transport, and a hotel, even if help is refused at first. Then check the airline's entry on the Transportation Department dashboard before arguing at the counter, because the promise that applies depends on the airline, the length of the delay, and whether the cause is still counted as controllable.
If the flight is canceled or significantly changed, decide about the alternative before accepting it. Accepting a rebooking ends the refund entitlement for that ticket, even if meals or a hotel later depend on the cause. If the airline will not provide help it promised for a controllable delay, the dashboard commitment and the written reason are the two pieces of evidence a complaint will need.
For February travel, the practical question at the gate is simple to state and harder to answer on the spot: which category did the airline put on this delay. That category, more than the length of the wait alone, will decide whether a meal voucher or a hotel room is part of the promise.
