Air Passenger Rights 2026: What You Get for a Delayed, Cancelled or Overbooked Flight (DOT, EU261 and What Changed)

Airlines run on a quiet advantage: most passengers do not know they are owed money, and those who do rarely know how much or how to ask. The result is billions in compensation left unclaimed every year.

The good news is that the rules are public, standardized by region and, in most cases, fixed in amount. You usually do not have to prove a loss. If the flight ran past the threshold, the sum is set.

This guide separates what applies in the United States (the newly strengthened DOT rules), in Europe (EU261, the most generous regime in the world) and under the Montreal Convention for baggage. And it shows, step by step, how to turn a ruined flight into money in your pocket.

US DOT: automatic cash refunds and the 2025 rules

TL;DRSince 2024-2025, the US Department of Transportation requires an automatic cash refund when a flight is cancelled or significantly changed and the passenger declines the alternative. The trigger is objective: a 3-hour domestic or 6-hour international delay. There is no fixed disruption compensation like EU261, but forced overbooking has its own denied-boarding payout.

The United States historically had weak rules compared to Europe, but that has changed. The DOT rules that took effect in 2024-2025 created a clear right to an automatic cash refund — not a voucher — whenever:

• A flight is cancelled or significantly changed and you reject the rebooking offered.
• Checked baggage arrives more than 12 hours late (refund of the bag fee).
• A paid extra service (Wi-Fi, seat, entertainment) is not delivered.

"Significant change" is now objective: a delay of 3 hours or more on a domestic flight, 6 hours or more international, a change of departure or arrival airport, or added connections.

What the US still does not have is the flat disruption compensation of EU261. You get your money back, but not the European €250-600 for simply being delayed. For involuntary denied boarding, however, there is a denied-boarding compensation table that can reach up to four times the fare, capped by the DOT.

EU261: the European rule that pays up to €600 per flight

TL;DRRegulation (EC) 261/2004 pays a flat sum for a delay over 3 hours at the destination, a cancellation without 14 days' notice and overbooking: €250 for flights up to 1,500 km, €400 between 1,500 and 3,500 km, and €600 above 3,500 km. It applies to any flight leaving the EU and arriving in the EU on a European carrier.

EU261 is the gold standard of passenger rights. It applies to every flight that departs an EU airport (on any airline) and to every flight that arrives in the EU operated by a European carrier. It also covers Iceland, Norway, Switzerland and the United Kingdom (which kept the rule as "UK261" after Brexit).

Delay compensation depends on two things: the distance of the flight and how late you arrived at the final destination.

Flight distance	Minimum arrival delay	Compensation
Up to 1,500 km	3 hours	€250
1,500-3,500 km (or intra-EU > 1,500 km)	3 hours	€400
Over 3,500 km	4 hours	€600

Note the detail most people miss: what counts is the delay on arrival, not departure. If the flight left 5 hours late but the crew made up time and you arrived only 2h40 late, there is no compensation. Conversely, a small departure delay that becomes 3h05 at the destination earns the full amount.

On flights over 3,500 km, if the delay falls between 3 and 4 hours, the compensation is halved (€300 instead of €600).

Overbooking: the situation that pays the most (and how to negotiate)

TL;DROverbooking is when the airline sells more seats than the aircraft holds and denies boarding to someone with a reservation. In the US, the DOT denied-boarding table can reach four times the fare. In Europe, it triggers the full EU261 band plus rebooking. Airlines must seek volunteers before bumping anyone by force.

Overbooking, or "denied boarding", is the practice of selling more tickets than seats, betting that some passengers will not show. When everyone shows up, someone gets left behind — and that is where the passenger holds the strongest hand.

In the US: involuntary denied boarding triggers the DOT compensation table, which can reach up to four times the one-way fare with a cap, paid in cash. The airline must first ask for volunteers willing to give up the seat for a negotiated benefit.

In Europe: being bumped against your will triggers immediate EU261 compensation in the same bands (€250, €400 or €600), plus rebooking and assistance. The airline must look for volunteers first.

The smart move: if the airline announces overbooking and asks for volunteers, negotiate. The first offer is rarely the ceiling. Ask for cash (not just a voucher), confirmation of the next flight, and assistance in writing before accepting.

When the airline does NOT have to pay: extraordinary circumstances

TL;DREU261 exempts the airline from the flat compensation when the delay results from an "extraordinary circumstance" beyond its control: severe weather, an air traffic control strike, a security risk, an airport closure. A technical fault on the aircraft, a crew shortage and a strike by the airline's own staff do NOT count as extraordinary.

The defense every airline tries is the "extraordinary circumstance". But the concept is narrower than they claim, and EU case law has closed the loopholes.

Counts as extraordinary (exempts the compensation, not the assistance):

• Severe weather preventing the flight
• A strike by air traffic controllers or airport staff (third parties)
• Political instability, security risk, closed airspace
• A bird strike requiring inspection

Does NOT count as extraordinary (you get the compensation):

• A technical/maintenance fault on the aircraft (the EU Court ruled it is part of normal operations)
• A crew shortage or rostering error by the airline
• A strike by the airline's own staff
• A "knock-on" delay from an earlier flight in the same fleet

Even in an extraordinary circumstance, the airline is still obliged to provide care — food, a hotel if you stay overnight, transport and communication. It only escapes the flat compensation payment.

The airline must prove it took "all reasonable measures" to avoid the delay. A generic weather claim is not enough. If other flights left the same airport at the same time, the weather argument weakens. Always ask for the reason in writing.

Lost, damaged or delayed baggage: the Montreal Convention

TL;DRLost, damaged or delayed baggage is governed by the Montreal Convention on international flights, with compensation up to about 1,288 SDR (≈ US$ 1,700 / €1,500) per passenger. The claim window is 7 days for damage and 21 days for delayed delivery, counted from the date you received (or should have received) the bag.

Baggage is governed by an international treaty, the Montreal Convention, which applies to virtually all international flights. The compensation limit is 1,288 Special Drawing Rights (SDR) per passenger — an IMF unit worth roughly US$ 1,700, €1,500 or the equivalent in local currency.

The deadlines are short, and missing one kills the right:

• Damaged baggage: claim in writing within 7 days of receiving the bag.
• Delayed baggage: claim within 21 days of delivery.
• Lost baggage: officially declared lost after 21 days of delay, then you claim the full amount.

The first step is always the PIR (Property Irregularity Report) at the airline desk, still at the airport, before you leave the baggage area. Without the PIR, the claim is weak. Keep every receipt for emergency purchases (clothes, toiletries) during the delay — they are reimbursable within the limit.

Tip: declaring a special value at check-in (for a fee) or buying travel insurance with baggage cover raises the ceiling above 1,288 SDR. Fragile items, expensive electronics and cash are usually not covered in checked baggage — always carry them on. Without a receipt, the airline tends to pay the minimum.

Connecting flights: when the late leg decides everything

TL;DROn a connection booked on a single ticket (one PNR), EU261 looks at the delay on arrival at the final destination, even if only the second leg was late and the original connection was outside the EU. Separate tickets break the protection: each leg becomes an isolated contract and you lose the combined cover.

The connection is where most people lose their right through ignorance. The golden rule: a single ticket (same record locator/PNR) treats the whole journey as one.

If you bought a single New York-Lisbon-Berlin ticket and missed the Lisbon connection because the first leg was late, what counts for EU261 is how late you arrived in Berlin (the final destination). If it was over 3 hours, compensation is due — and the distance considered is that of the full journey, which can push it into the €600 band.

The opposite is the separate-ticket trap. If you bought New York-Lisbon on one airline and Lisbon-Berlin on another, with independent bookings, those are two isolated contracts. If the first is late and you miss the second, the first airline owes nothing for the second flight and you pay the rebooking. Saving money on standalone legs can cost you dearly right here.

Another protection of the single ticket: if the connection is at an EU airport and the airline is European, even a flight originating outside Europe can fall under EU261 cover on the intra-EU portion.

How to claim without a lawyer and without losing a percentage

TL;DRThe initial claim is free and you do it yourself: gather your boarding pass, proof of the delay and the booking confirmation, send a formal complaint to the airline citing the DOT or EU261, and set a deadline to reply. Refund companies charge 25% to 50% — worth it only if the airline refuses and the case goes to court.

You do not need to pay anyone for the first request. The process is direct:

1. Gather the evidence: boarding pass, confirmation email, photos of the board showing the delay, and any airline communication. Photograph the departure board showing "delayed" or "cancelled".
2. Calculate the amount: identify the flight distance and the arrival delay to find the band (EU261) or the refund/care rights (DOT).
3. File a formal complaint with the airline: in writing, on the official channel, explicitly citing the applicable rule (DOT or EU261). Be precise: flight number, date, delay, amount requested.
4. Set a deadline and escalate: if the airline refuses or goes silent, in the US file with the DOT (transportation.gov/airconsumer); in Europe, with the National Enforcement Body of the airport's country.
5. Only then consider third parties: refund companies (AirHelp, ClaimCompass and similar) charge 25-50% and make sense only if you do not want to handle a refusal and the court route.

Deadlines to claim: up to 6 years in the UK, 2-3 years in most of the EU, and in the US within the carrier's contract statute. Do not let it lapse.

One detail that raises the success rate: cite the rule by number and be specific about the amount. A letter that says "I was wronged, I want my rights" earns less than one that says "flight XX1234 on 12 March, 4h10 late on arrival in Frankfurt, distance 9,800 km, I request €600 under Art. 7 of Regulation 261/2004". Precision signals that you know the rule and makes a generic refusal harder. If the first reply rejects it citing an extraordinary circumstance, ask for documentary proof of the reason — many airlines drop the defense when confronted, because they lack the document.

Finally, keep everything in writing. A phone call is not evidence. Email, official chat and case numbers are what sustain the claim if it goes to court or a regulator.

Practical appendix — the problem-flight checklist

At the airport, immediately:

• Photograph the board showing the status (delayed/cancelled).
• Demand the reason for the delay in writing (ask at the desk).
• Keep the boarding pass and do not throw away any receipt.
• For baggage: open the PIR before leaving the baggage area.
• Keep receipts for food, hotel, transport and emergency purchases.

Documents for the claim:

• Boarding pass + booking confirmation (PNR).
• Proof of the actual arrival time.
• Airline communications (email, SMS, app).
• Receipts for extra expenses.

Where to complain:

• US: airline → DOT (transportation.gov/airconsumer).
• Europe: airline → National Enforcement Body of the airport's country.
• UK: airline → CAA or an ADR scheme.
