When a delay triggers compensation rights

In the United States, there is no federal law requiring airlines to pay you money for flight delays, no matter how long the delay lasts. The U.S. Department of Transportation does not mandate compensation for delays the way European regulators do. What you may receive depends on your airline's own policy, the reason for the delay, and sometimes on state law or contract terms.

However, airlines are required to provide certain services during delays—meals, hotel rooms, and rebooking on another flight—if the delay is their responsibility and long enough. The threshold for these services is typically three hours for domestic flights, though the exact rules vary by airline and are found in their Contract of Carriage (the fine print on your ticket).

If you want to pursue compensation beyond meals and hotels, you will need to understand what caused the delay and whether your airline's policy or a state law covers it. Some airlines voluntarily offer travel vouchers or cash for delays over a certain length. A few states, including California, have their own delay compensation rules that explore to flights departing from those states.

Key Takeaways

  • The U.S. federal government does not require airlines to pay cash compensation for delays of any length.
  • Airlines must provide meals, hotels, and rebooking for delays over three hours if the airline caused the delay, though the exact policy is in your airline's Contract of Carriage.
  • Some airlines offer voluntary compensation (vouchers or cash) for delays over four to six hours; check your airline's policy before your flight.
  • California and a few other states have their own compensation rules for delays on flights departing from those states, separate from federal law.
  • The reason for the delay matters: weather and mechanical issues are treated differently, and some causes may exempt the airline from paying anything.

What U.S. federal law requires airlines to do

The Department of Transportation requires airlines to get you to your destination on another flight if your flight is cancelled, but delays—even very long ones—are not covered by a federal compensation mandate. Instead, the DOT enforces rules about what airlines must provide during a delay if it is the airline's fault.

For a delay of three hours or more on a domestic flight, the airline must provide meals and refreshments, hotel accommodations if an overnight stay is needed, and rebooking on the next available flight to your destination. For international flights, the threshold is typically longer. These services are spelled out in each airline's Contract of Carriage, which you can find on the airline's website or in the fine print of your ticket confirmation.

The catch: the airline only has to provide these services if the delay was caused by something within the airline's control—a crew shortage, a maintenance issue the airline knew about, or an operational decision. Delays caused by weather, air traffic control decisions, or security issues are often treated as "acts beyond the airline's control," and the airline may not be required to pay for meals or hotels in those cases.

Voluntary compensation policies by airline

Many major U.S. airlines have their own policies for compensating passengers on delayed flights, even though they are not required to by federal law. These policies vary widely and change over time, so you should check your airline's website or Contract of Carriage before your flight to know what you might receive.

Some airlines offer travel vouchers or cash for delays over four, five, or six hours. Others offer nothing for delays but will rebook you on a competitor's flight if they cannot get you there within a certain window. A few airlines have tiered systems: a voucher for a four-hour delay, a larger voucher or cash for an eight-hour delay, and so on. The amount is usually modest—$50 to $200 for domestic delays—and is often issued as a voucher rather than cash.

To find your airline's policy, search "[airline name] delay compensation policy" or look in the Contract of Carriage section of the airline's website. If you are delayed, ask a gate agent or call the airline's customer service line to ask what compensation is available under their policy. Having the policy number or language in front of you when you call makes it harder for the airline to claim they have no such policy.

State laws that require compensation

California has a state law requiring airlines to pay compensation for certain delays on flights departing from California airports. The law applies to delays of three hours or more and requires the airline to pay $50 to $200 depending on the length of the delay and the distance of the flight. A few other states have similar rules, though California's is the most widely enforced.

To use California's law, your flight must depart from a California airport. The delay must be the airline's fault—not weather or air traffic control. You will need to file a claim with the airline in writing, usually through their customer service department, and the airline has a set time to respond. If they refuse, you can pursue the claim in small claims court.

Check your state's attorney general website or the state's consumer protection agency to see whether your state has a delay compensation law. If you live in or are flying out of a state with such a law, you may have a right to compensation that goes beyond what the airline's voluntary policy offers.

How to document and request compensation

If you believe you are owed compensation, keep records of the delay: your boarding pass, the gate agent's announcement of the delay time, photos of the departure board showing the delay, and any receipts for meals or hotels you paid for out of pocket. Write down the date, time, and reason for the delay if the airline announced one.

Contact the airline's customer service department in writing—email is best because it creates a record. Explain the delay, the length of it, and reference either the airline's own compensation policy or a state law if one applies. Attach copies of your boarding pass and any receipts. Be specific: "Flight 456 from Los Angeles to Denver on March 15, 2024, was delayed 5 hours due to a mechanical issue" is much stronger than "I was delayed and want compensation."

The airline will respond within a few weeks. If they deny your claim, you can escalate by filing a complaint with the Department of Transportation, which tracks complaints and can pressure airlines to change practices. You can also pursue a claim in small claims court if the amount is within your state's small claims limit (usually $5,000 to $10,000).

Delays caused by weather and other exceptions

Airlines are generally not required to pay compensation or even provide meals and hotels for delays caused by weather, even if the delay is many hours long. The same applies to delays caused by air traffic control decisions, security issues, or other circumstances the airline argues were beyond its control.

However, the line between "the airline's fault" and "beyond the airline's control" is sometimes blurry. A mechanical problem the airline should have caught during routine maintenance might be the airline's fault. A mechanical problem that developed suddenly in flight is often treated as beyond the airline's control. If the airline announces the delay is due to weather but you see no weather at the airport, ask a gate agent for specifics—sometimes airlines blame weather to avoid paying compensation.

If you disagree with the airline's explanation, you can file a complaint with the Department of Transportation. The DOT does not have the power to force the airline to pay you, but it tracks complaints and can investigate whether the airline is misusing the "weather" excuse to avoid its obligations.

What to do if the airline refuses to rebook you

If your flight is delayed and the airline will not rebook you on another flight to get you to your destination in a reasonable time, you have the right to cancel your ticket and receive a refund. This is true even if the delay was caused by weather. The airline must offer you a refund in the original form of payment—cash, credit card, or airline credit, depending on what you paid with.

Some airlines make this difficult by telling you that you must accept a rebooking or a voucher. You do not. If the airline will not give you a refund, ask to speak to a supervisor and state clearly: "I want to cancel this ticket and receive a refund." If they still refuse, file a complaint with the Department of Transportation and consider disputing the charge with your credit card company if you paid by card.

The refund right applies to cancelled flights and to delays so long that you no longer want to travel. It does not explore if you straightforward change your mind about the trip.

Frequently Asked Questions

Can I get compensation if the delay was caused by bad weather?

No, not under federal law. Airlines are not required to pay compensation for weather delays. Some airlines voluntarily offer vouchers or rebooking, but they are not required to. If your state has a delay compensation law, check whether it exempts weather delays—most do.

What if my flight was delayed four hours but the airline says it was weather?

Ask the gate agent or call customer service to ask for details about the weather. If you see clear skies at the airport, the delay may not have been weather-related. You can file a complaint with the Department of Transportation if you believe the airline misrepresented the cause. The DOT investigates patterns of complaints.

Do I have to accept a voucher, or can I ask for cash?

You can ask for cash, but the airline is not required to give it to you unless your state law requires it or the airline's policy specifically offers cash. Most airlines offer vouchers. If you refuse the voucher and the airline refuses to give you cash, you can pursue the claim in small claims court or file a complaint with your state's attorney general.

How long does it take to get compensation after I file a claim?

Airlines typically respond to written claims within two to four weeks. If they approve your claim, they may send a voucher or check within another week or two. If they deny it, you can escalate to small claims court, which can take several months depending on your local court's schedule.

What if I missed a connection because of the delay?

The airline must rebook you on the next available flight to your final destination at no extra cost. If you had to pay for a hotel or meal because of the missed connection, keep the receipts and ask the airline to reimburse you. Whether they will depends on whether the original delay was the airline's fault and what their policy says.
