You may be owed money for a delayed flight, but the amount and your right to it depend on where you flew, how long the delay was, and why it happened

If your flight arrived more than three hours late, you may have a right to cash compensation under U.S. Department of Transportation (DOT) rules or European Union regulations, depending on where your flight departed and landed. The airline does not automatically send this money — you have to request it, and the airline can refuse if the delay was caused by weather, mechanical problems they claim were unforeseen, or air traffic control issues. Compensation ranges from $250 to $750 per passenger under DOT rules, or €250 to €600 under EU rules, but only if specific conditions are met.

Key Takeaways

  • The U.S. Department of Transportation requires airlines to compensate passengers for delays over three hours caused by the airline's own actions, but not for weather or mechanical failures.
  • European Union rules are stricter: airlines must pay €250 to €600 even for some weather delays, depending on flight distance, unless the delay was truly extraordinary.
  • You must submit a written claim to the airline within the timeframe stated in their contract of carriage, usually 30 to 60 days after the flight.
  • If the airline denies your claim, you can file a complaint with the DOT or take the airline to small claims court, but you cannot force them to pay through a government agency.
  • Airlines often deny claims by saying the delay was caused by weather or maintenance, so keeping your boarding pass, flight records, and proof of the delay helps your case.

How U.S. compensation rules work

Under DOT rules, an airline must compensate you if your flight arrived at your final destination more than three hours late and the delay was within the airline's control. The airline's control means things like crew scheduling, mechanical problems the airline should have caught during routine maintenance, or overbooking. The compensation is 100% of your one-way ticket price, up to $775, or 50% of that amount if the airline gets you to your destination between one and three hours late.

The airline does not have to pay if the delay was caused by weather, air traffic control decisions, security threats, or mechanical problems the airline says were not foreseeable. This is where most denials happen: the airline claims the delay was weather-related or a sudden mechanical failure, and you have to prove otherwise. If you booked through a third party like Expedia or Kayak, you still claim from the airline that operated the flight, not the booking site.

The airline's contract of carriage — the fine print you agree to when you buy a ticket — sets the important date for filing a claim, usually 30 to 60 days after the flight. Check your airline's website or your confirmation email for the exact important date and the address or online form where you submit the claim. Missing the important date usually means the airline can reject your claim without reviewing it.

How European Union compensation rules work

If your flight departed from an EU airport or arrived at an EU airport on an EU airline, EU Regulation 261/2004 applies. Under this rule, the airline must pay you €250 to €600 depending on the flight distance, even if the delay was caused by weather — unless the airline can prove the weather was so extreme that no airline could have prevented the delay. This is a much higher bar than U.S. rules set.

The compensation amounts are: €250 for flights up to 1,500 kilometers, €400 for flights between 1,500 and 3,500 kilometers, and €600 for flights over 3,500 kilometers. The delay must be at least three hours at your final destination. The airline can reduce the compensation by 50% if they offer you a flight to your destination within two hours of your original arrival time, but they must still pay something.

Airlines can refuse to pay only if they prove the delay was caused by extraordinary circumstances — severe weather, volcanic ash, air traffic control strikes, or security risks — that they could not have avoided even with reasonable care. A mechanical failure, crew shortage, or fuel issue does not count as extraordinary unless the airline can show it was truly unforeseeable. You submit your claim directly to the airline, and if they refuse, you can file a complaint with your national aviation authority or take them to court in your home country.

What counts as a delay for compensation purposes

The delay is measured from when your flight actually touched down at your final destination, not when it was supposed to land. If you were scheduled to arrive at 2:00 p.m. and landed at 5:15 p.m., that is a three-hour-and-15-minute delay. If you missed a connecting flight and arrived at your true final destination hours later, the delay is still measured from when the delayed flight landed, not from when you finally reached your destination.

If the airline rebooks you on another flight and you arrive more than three hours late, you are still owed compensation for the original delay. The compensation does not change based on how much you paid for the ticket — a passenger who paid $100 and a passenger who paid $1,000 on the same flight get the same compensation under DOT rules. Under EU rules, compensation is the same for all passengers on the same flight, regardless of ticket price.

How to file a claim with the airline

Start by finding your airline's contract of carriage on their website, usually under "Terms and Conditions" or "Legal." Look for the section on denied boarding, delays, or compensation. This section will tell you the important date for filing, the address or online portal where you submit your claim, and what documents you need to include.

Write a letter or fill out the airline's online form with the following information: your name, confirmation number, flight number, scheduled departure and arrival times, actual arrival time, and the reason you believe you are owed compensation. Attach a copy of your boarding pass, your ticket receipt, and any proof of the delay — a photo of the departure board, an email from the airline about the delay, or a screenshot of your flight status from the airline's app. Keep copies of everything you send.

Send your claim by email or mail, depending on what the airline's contract says. If you use email, request a read receipt so you have proof the airline received it. If you use mail, send it certified mail with return receipt requested. The airline has 30 to 60 days to respond, depending on their policy. If they deny your claim or do not respond within that time, you can file a complaint with the DOT or pursue the claim in small claims court.

What to do if the airline denies your claim

If the airline refuses to pay, you have two main options: file a complaint with the U.S. Department of Transportation, or take the airline to small claims court. The DOT does not have the power to force the airline to pay you directly, but a complaint on record can pressure the airline and may help other passengers. You file a DOT complaint on their website at transportation.gov. The DOT will forward your complaint to the airline, and the airline must respond within 30 days.

Small claims court is often faster and more effective. You sue the airline in the small claims court in your county for the compensation amount plus court costs. The limit for small claims varies by state, usually between $5,000 and $25,000, so most flight compensation claims fit within the limit. You do not need a lawyer, and the process is designed for people without legal training. Bring your boarding pass, ticket receipt, proof of the delay, and a copy of the airline's denial letter.

Some passengers use third-party claim services that file the claim on your behalf and take a percentage of the compensation if they win. These services can be useful if you do not want to handle the claim yourself, but they typically take 25% to 50% of the payout. If you file the claim yourself, you keep 100% of what you recover.

Why airlines often deny delay compensation claims

The most common reason airlines deny claims is that they say the delay was caused by weather. Weather is a legitimate reason to deny compensation under U.S. rules, but under EU rules, the airline still has to pay unless the weather was truly extraordinary. If the airline says the delay was weather-related, ask them to provide the specific weather data or National Weather Service report that caused the delay. If the weather was minor or localized, you may have a case that the airline should have planned around it.

Mechanical failures are another common reason for denial. The airline will say the delay was caused by an unexpected mechanical problem that they could not have foreseen. If the aircraft had a history of the same problem, or if the airline failed to perform required maintenance, you may be able to argue the failure was foreseeable. Request the aircraft's maintenance records if you pursue the claim in court — the airline may have to produce them.

Crew scheduling issues, fuel delays, and air traffic control delays are also common reasons for denial. Under U.S. rules, crew scheduling and fuel issues are usually the airline's responsibility, so denials based on these reasons are often wrong. Under EU rules, the airline must pay regardless. If the airline blames air traffic control, ask for documentation from the FAA or the relevant air traffic control facility confirming the delay was their fault.

Frequently Asked Questions

Do I get compensation if I booked a cheap ticket or used a voucher?

Under DOT rules, compensation is based on your ticket price, up to $775. If you paid $50 for the ticket, your compensation is capped at $50. If you used a voucher or frequent flyer miles, the airline may argue you did not pay a cash price and owe you nothing, though this is disputed. Under EU rules, compensation is the same regardless of what you paid, so a voucher ticket gets the same €250 to €600 as a full-price ticket.

What if the airline offers me a voucher instead of cash?

Under DOT rules, the airline must offer you cash compensation, not a voucher. If they offer a voucher, you can refuse it and demand cash. Under EU rules, the airline must offer cash, but you can choose to accept a voucher or other compensation if you prefer. Always ask for cash unless you are certain you will use the voucher.

Can I claim compensation if I missed my connection because of the delay?

Yes, if the delay on your first flight caused you to miss a connecting flight and you arrived at your final destination more than three hours late, you can claim compensation for the original delayed flight. The compensation is based on the delay to your final destination, not the delay to the connection point.

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

If the airline approves your claim, they typically pay within 30 to 60 days. If you file a complaint with the DOT or take the airline to small claims court, the process can take several months. Small claims court usually schedules a hearing within two to four months, and the judge's decision is usually final.

Do I need a lawyer to file a claim or go to small claims court?

No, you do not need a lawyer to file a claim with the airline or to appear in small claims court. Both processes are designed for people without legal training. A lawyer can help, but the cost of hiring one usually exceeds the compensation amount, so most people handle these claims themselves.
