Starting Oct. 19, 10 kinds of flight delays stop counting as the airline's fault. That could cost you a hotel

On Oct. 19, a new federal rule changes who gets blamed when your flight is late. Ten kinds of delays and cancellations will no longer count as the airline's fault in government data. The Department of Transportation says that will likely mean fewer free meals, hotel rooms and other perks for stranded travelers.

Your right to a cash refund does not change. But if you count on the airline to cover dinner during a long delay, this rule matters.

What the rule actually does

Since 2002, large US airlines have reported the cause of every delay of 15 minutes or more, and of every cancellation, to the government. Each one goes into a bucket. One of them is "Air Carrier," which covers problems the airline controls, like crew shortages or maintenance.

The final rule, published in the Federal Register on Sept. 3, adds a new bucket called "Section 511(b)." It takes effect Oct. 19, 2026. Ten events must go into this new bucket instead of the airline's:

1. Cleaning a plane after a passenger dies
2. Damage to a plane from extreme weather, debris on the ground or sabotage
3. Bag or cargo loading delays from a baggage system outage the airline and its contractors don't control
4. Cyberattacks, if the airline follows the cybersecurity rules that apply to it
5. Sudden shutdowns or failures of government systems that affect safe flying
6. Overheated brakes after a safety incident that needed emergency procedures
7. Unscheduled maintenance that shows up outside the normal maintenance program and can't wait, including fixes ordered by an airworthiness directive
8. A medical emergency that was not the airline's fault
9. Removing an unruly passenger
10. An airport closure because of volcanic ash, wind or wind shear

DOT did not pick these. Congress wrote the list into Section 511(b) of the FAA Reauthorization Act of 2024, which became law on May 16, 2024. The law says these events "shall not be included" in the Air Carrier code. Because the agency had no choice, it skipped the usual public comment period.

Why your dinner voucher is at risk

Here is the part travelers should care about. DOT says every large airline that reports this data and sells tickets has promised, in its customer service plan, to give free amenities during long delays and cancellations that are within its control. Some also promise non-cash compensation, like travel credits.

DOT says outright that the rule will shrink those handouts. In its own analysis, the agency writes that "the number of delays and cancellations for which air carriers provide amenities and compensation to consumers is expected to be reduced." It says it can't estimate by how much, because it doesn't know how often these 10 events happen. It calls the lost value a "transfer of value from consumers back to air carriers."

The list matters because some of these events are common. A sick passenger, an unruly flyer or a surprise repair can ground a flight for hours. Before, the airline would usually report that as its own delay. After Oct. 19, those cases go into the new bucket.

What does not change

Refunds are a separate rule. Under federal refund rules, an airline must give a full cash refund if it cancels your flight or delays it significantly and you choose not to fly. A significant delay means three hours or more on a domestic trip, or six hours or more on an international one. The refund rule does not depend on whose fault the delay was. If you turn down the late flight, rebooking and any voucher, you are owed your money back, taxes and fees included.

The rule also doesn't change which airlines report data or which flights count.

Our take: the airline-friendly part is the small print

DOT and the airlines' main trade group say the old data blamed airlines for things they could not stop. DOT calls that "overreporting." That argument has some weight for volcanic ash or a cyberattack.

But the list also includes unscheduled maintenance, and an airline's own fleet is hard to call outside its control. DOT's analysis lists "the reduction in negative reputational impacts" for airlines as a benefit. Travelers get cleaner-looking delay stats. Airlines get to hand out fewer meals and hotel nights. That trade deserves more attention than it got.

More may be coming. DOT says it will write a separate rule for delays caused by air traffic control. An airline trade group has also asked for more changes, and DOT says those will go through public comment.

How to protect yourself

• Ask why you're delayed. The reason now decides whether you get a voucher. Write down what the gate agent and the app say.
• Know your refund line. Three hours domestic, six hours international. Past that, you can turn down the flight and get your money back.
• Check your card. Some premium cards include trip delay insurance that pays for meals and hotels no matter who caused the delay. Read your card's benefit guide before you fly.
• Have a place to wait. A lounge membership or card that gets you in turns a long wait into a free meal and a quiet seat. If your hub is crowded, see our look at the 80-minute line at Delta's LaGuardia Sky Club before you count on getting in.
