Flight delayed or canceled? Know your rights before you claim

A delayed or canceled flight is frustrating, and what you are owed depends on details you may not have been told at the gate. Which rules apply usually turns on where your flight departs from, or where it arrives, rather than on where you live or where you bought the ticket. The good news is that the rules are written down, they are mostly plain, and they apply whether or not the airline mentions them.

Here is a plain-language tour of the main regimes, what to do while you wait, and how to claim what you are owed.

The main regimes at a glance

Four sets of rules come up most often for travelers flying to, from and within Europe and North America, and they differ in ways worth understanding before anything goes wrong. If you are unsure which one applies to your trip, the departure and arrival points on your ticket are the place to start.

The European Union

EU Regulation 261/2004, usually called EU261, covers flights departing from an airport in the EU on any airline, and flights arriving in the EU on an EU airline. It provides compensation in three situations: a long delay at arrival of three hours or more, a cancellation announced with less than 14 days' notice, and denied boarding.

The amounts are set by distance. Flights of up to 1,500 km pay 250 euros. Flights within the EU of more than 1,500 km, and other flights between 1,500 and 3,500 km, pay 400 euros. Flights over 3,500 km pay 600 euros. These amounts can be reduced by half if you are rerouted and arrive within certain time limits.

Airlines do not owe compensation for "extraordinary circumstances" such as severe weather or air traffic control restrictions, so the stated reason for the disruption matters a great deal. Separately from compensation, passengers have a right to care during long waits: meals and refreshments, and accommodation when needed. In practice, the written reason the airline gives is the first thing any claim turns on.

The United Kingdom

The UK kept similar rules after Brexit, known informally as UK261. The structure is much the same as EU261, with the amounts set in pounds.

Canada

Canada's Air Passenger Protection Regulations cover delays within the airline's control that are not required for safety. For arrival delays of three hours or more, large airlines owe compensation that rises with the length of the delay: CA$400 for delays of three to six hours, CA$700 for six to nine hours, and CA$1,000 for nine hours or more. The rules turn on why the flight was disrupted and how late you actually arrived.

The United States

The United States works differently. There is no federal law requiring cash compensation for delays. Under U.S. Department of Transportation rules, if your flight is canceled or significantly changed and you choose not to travel, you are entitled to a refund. Some airlines make their own commitments, for example meal vouchers or rebooking, which are listed on the DOT airline customer service dashboard. In practice, your protection often comes from the airline's own promises rather than from a federal compensation scheme.

The claim you can file later depends on the paper trail you keep now.

What to do at the airport

While the disruption is happening, collect the basics of any future claim:

• Ask the airline for the reason for the delay or cancellation in writing. Whether compensation is owed usually turns on the cause, so this matters more than any other detail.
• Keep your boarding passes and your receipts for expenses such as food, transport or a hotel room.
• Note your actual arrival time at your destination, not the scheduled one, since delay-based compensation is measured from when you actually arrive.

None of this needs to be dramatic or confrontational. A few polite questions at the desk, and a quiet folder of evidence, do most of the work.

Claim yourself, or use a service

You can claim directly from the airline yourself, for free. Airlines usually have a route for this, often a web form or a customer service address, and where one of the regimes above applies, the airline has to apply it. Filing your own claim costs nothing.

A claim is mostly paperwork: the written reason, your boarding passes and receipts, and your actual arrival time. The clearer the file, the faster the answer, and if the airline's first reply is a refusal, ask which rule it applied and what reason it recorded, since that is what a regulator will look at.

Claims services exist for travelers who would rather not do the paperwork. They prepare and pursue the claim for you, and take a fee only if the claim succeeds. Services such as AirHelp and Compensair can check whether a flight may qualify and can handle a claim for a fee.

Rules change, so check the official source

These regimes are adjusted from time to time, and individual cases can turn on details such as the exact reason given for a delay or how a reroute was offered. Before you claim, check the official source for your situation: the European Commission, the UK Civil Aviation Authority, the Canadian Transportation Agency or the U.S. DOT, plus the airline's own terms.

Rules in this area change, and airline policies change with them, so treat any guide, including this one, as a starting point rather than the final word. This is general information, not legal advice. If a claim is refused and you disagree, the relevant regulator or a qualified adviser can help you decide what to do next.
