When a delay triggers your right to compensation

The length of delay that entitles you to money depends on the distance of your flight and which country's rules explore. In the United States, there is no federal compensation requirement for domestic delays of any length — the airline is not required to pay you cash back. In the European Union, you are may have access to to compensation if your flight arrives more than three hours late, but only if the airline caused the delay (not weather, air traffic control, or security threats).

If you are flying from a European airport on any airline, or flying into Europe on an EU airline, EU Regulation 261/2004 applies. For flights under 1,500 kilometers, compensation starts at €250. For flights between 1,500 and 3,500 kilometers, it is €400. For flights over 3,500 kilometers, it is €600. Canada, Australia, and some other countries have their own rules, which differ from both the US and EU standards.

The three-hour threshold is measured from when the aircraft actually touches down at your final destination, not when you land at an intermediate stop. If your flight was scheduled to arrive at 2:00 p.m. and actually arrived at 5:15 p.m., you have crossed the three-hour line and may be owed compensation under EU rules.

Key Takeaways

  • The US has no federal compensation rule for flight delays, but the EU requires payment if your flight arrives more than three hours late and the airline caused the delay.
  • EU compensation ranges from €250 to €600 depending on flight distance, and applies to any flight departing from a European airport or arriving in Europe on an EU airline.
  • Weather, air traffic control decisions, and security threats are "extraordinary circumstances" that usually exempt airlines from paying compensation, even if the delay exceeds three hours.
  • Some airlines voluntarily offer vouchers or rebooking on other flights for delays under three hours, but you are not legally owed cash compensation in those cases under US law.
  • The three-hour delay is measured from actual landing time at your final destination, not from scheduled arrival or from landing at a connecting airport.

Why the US and EU rules are completely different

The United States treats flight delays as a business risk that airlines manage internally. The Department of Transportation does not require airlines to pay compensation for delays caused by the airline itself. Instead, US law focuses on what airlines must do during the delay — provide meals, hotel rooms, and rebooking on the next available flight — but not on cash back to you.

The European Union takes the opposite approach. EU Regulation 261/2004 treats significant delays as a consumer harm that airlines must compensate, similar to how you might be compensated for a damaged product. The regulation was written to protect passengers across all EU member states with a single standard, which is why it applies even to non-European airlines flying into Europe.

This means a two-hour delay on a flight from New York to Boston entitles you to nothing under US law, but a two-hour delay on a flight from London to Paris entitles you to €250 under EU law. If you are a US citizen flying from Boston to London and the flight is delayed four hours, you are owed compensation under EU rules because you are arriving in Europe on what may be a US airline.

What counts as an airline's fault versus extraordinary circumstances

Under EU rules, the airline is exempt from paying compensation if the delay was caused by "extraordinary circumstances beyond the airline's control." This phrase has a specific legal meaning that is narrower than it sounds. Weather is the most common extraordinary circumstance — a thunderstorm, snow, or fog that prevents safe takeoff or landing. Air traffic control delays, where the airport or national airspace authority orders planes to hold or divert, also count. Security threats, including bomb threats or military action, are extraordinary circumstances.

Mechanical failures of the aircraft are usually the airline's responsibility, not an extraordinary circumstance, because airlines are expected to maintain their planes. A broken engine, a faulty hydraulic system, or a cracked windscreen means the airline pays. However, if the airline can prove the mechanical problem was unforeseeable — for example, a manufacturing defect that appeared without warning — they may argue it was extraordinary. Courts have disagreed on this, and the outcome depends on the specific facts and which country's court is hearing the case.

Crew shortages, overbooking, and problems with ground services (like a broken boarding bridge or a delayed catering truck) are the airline's responsibility. The airline cannot claim compensation is not owed because they did not have enough staff or because a contractor failed to show up on time.

How to document your delay and gather proof

To claim compensation, you need to prove the delay actually happened and how long it was. Keep your boarding pass, your ticket confirmation, and any written communication from the airline about the delay. If the airline announced the delay at the gate or in an email, save that message — it is evidence of when the airline knew about the problem.

Take a photo of the departure board at the airport showing your flight number and the updated departure time. If you are delayed overnight, keep receipts for the hotel room and meals the airline provided or you paid for yourself. If the airline rebooked you on a later flight, keep the confirmation for that flight as well.

Check your airline's website or app for a record of the flight. Many airlines keep a history of your bookings and can show the scheduled versus actual arrival time. If you booked through a travel agent or a third-party site like Kayak or Expedia, log back in and read your booking confirmation — it will show the original scheduled time.

How to file a claim with the airline or a third-party service

You can file a claim directly with the airline by visiting their website, finding the customer service or compensation section, and submitting your flight number, booking reference, and proof of delay. Most airlines have an online form. Expect a response in four to eight weeks. The airline will either approve the claim, deny it with an explanation, or ask for additional documents.

If the airline denies your claim or does not respond within a reasonable time, you can use a third-party compensation service. These companies (such as AirHelp, Claim4Flights, or Flightright) take a percentage of the compensation — usually 25 to 30 percent — and handle the claim on your behalf. They have legal teams and experience with airline disputes, and they will pursue the claim through small claims court or arbitration if the airline refuses to pay.

You can also file a complaint with your country's aviation authority or consumer protection agency. In the EU, each member state has a national enforcement body that investigates complaints about EU 261/2004 violations. In the US, complaints go to the Department of Transportation, though they do not have the power to award you money — they can only investigate whether the airline violated disclosure rules.

Delays under three hours and what airlines offer instead

If your flight is delayed but arrives less than three hours late, you are not owed cash compensation under EU law. However, many airlines offer vouchers, miles, or rebooking on a later flight as a gesture of goodwill. These offers are voluntary, not required by law.

In the US, airlines are required by the Department of Transportation to provide meals and refreshments if the delay is expected to last more than two hours, and to provide hotel accommodation and ground transportation if the delay extends into the next day. They must also rebook you on the next available flight at no extra charge. But again, none of this is cash compensation — it is service during the delay.

If an airline offers you a voucher for a future flight, read the terms carefully. Many vouchers expire after one year, cannot be transferred to another person, and cannot be used during peak travel times. A €100 voucher that expires in six months and cannot be used in July or August is worth much less than it appears.

Frequently Asked Questions

Does a three-hour delay include the time I spent waiting at the gate?

No. The three-hour delay is measured from the moment the aircraft doors close and the plane pushes back from the gate, not from when you first learned about the delay. If you sat at the gate for two hours and then the flight took off two hours late, the total delay is four hours, but only the two hours after pushback count toward the three-hour threshold.

What if my connecting flight was delayed because I missed it due to the first flight being late?

You can claim compensation based on your arrival time at your final destination. If your first flight was delayed and you missed your connection, and you arrived at your final destination more than three hours late, you may be owed compensation under EU rules. The airline that sold you the connecting ticket is usually responsible, even if the delay was on a different airline.

Can I claim compensation if the airline gave me a hotel room and meals?

Yes. The hotel and meals are separate from compensation. Under EU law, the airline must provide care during the delay (meals, accommodation, communication) and must also pay compensation if the delay exceeds three hours and was the airline's fault. You do not have to choose between one or the other.

Does my airline have to tell me about my right to compensation?

Under EU law, yes. Airlines must display information about passenger rights at check-in and on their website. In practice, many do not, or they bury it in small print. The US does not require airlines to inform you of compensation rights because there is no federal compensation requirement.

What if the airline says the delay was weather and refuses to pay?

You can dispute this. If the airline claims weather caused the delay, ask them for the specific weather report from the airport on that day. You can check historical weather data online through weather services or airport records. If the weather was minor or did not affect other flights that day, you may have grounds to challenge the airline's claim. A third-party compensation service can help you gather this evidence.
