There is no single passenger-rights code for every international flight. Which rules may apply depends on each flight leg, where it departs and arrives, and sometimes the airline that operates it. Before you travel, map your itinerary, check the official rules for the relevant countries, and save the rules and complaint details with your booking.

1. Map the flight leg by leg

Do not check only the country where your trip begins or the airline whose name appears on your ticket. A connection can introduce another jurisdiction, and the operating carrier can matter even when a different airline sold or marketed the flight.

Record for each leg What to write down
Departure and arrival Airport, country, and scheduled date and time for each end of the leg.
Connections Every connection airport and country, including whether you change flights or airlines.
Airline Both the marketing airline shown on the booking and the operating airline, if different.
Booking details Booking reference, ticket number, fare conditions, and any separate ticket or package-travel information.

Keep the itinerary as booked; if the airline later changes a leg or reroutes you, save that version too. The route and operating-carrier tests differ by jurisdiction, so a change can affect which rules are relevant.

2. Check the official rules for each jurisdiction

Start with official passenger-rights guidance from the departure country, arrival country, and any country whose rules may cover a connection or the operating carrier. Confirm important details on the regulator’s website or in the applicable legislation rather than relying only on an airline summary or a general travel article.

The International Civil Aviation Organization (ICAO) maintains a country-by-country aviation consumer-protection database that can help you locate national rules. ICAO describes it as non-exhaustive, and some linked material may not be available in English. Treat it as a directory, then verify the rule with the relevant national authority.

United Kingdom

UK Department for Transport guidance says the UK disruption rules cover flights departing a UK airport on any airline; flights arriving in the UK on a UK or EU airline; and flights arriving in the EU on a UK airline. For eligible cases, the guidance describes care and support after a qualifying delay of at least two hours. Delay compensation generally requires arrival at the final destination more than three hours late and airline responsibility. A cancellation may give you a choice between a refund and rerouting, and may also qualify for compensation depending on notice and the alternative flight. These are general conditions, not a decision on an individual claim.

European Union

The Council of the European Union says EU passenger rights apply to flights within the EU, flights departing the EU for a non-EU country, and flights arriving in the EU from outside it on an EU airline. The test described by the Council is not based on the passenger’s citizenship.

For qualifying cancellation or long-delay cases, the Council’s 2026 summary lists possible compensation of €250 for flights of 1,500 km or less; €400 for intra-EU flights and flights between 1,500 and 3,500 km; and €600 for other flights. Those amounts are not automatic: check the applicable conditions and the facts of your disruption in the EU passenger guide, Your Europe, and the governing legislation.

EU rules have also been revised. In a notice dated 13 July 2026, the Council said the revised rules had received final clearance and would enter into force 12 months and 20 days after publication in the Official Journal. The notice does not state that publication date, so it does not establish a calendar date when the revised provisions begin to apply. Check the Official Journal and current official guidance before relying on the amendments; do not assume that final clearance means they already apply.

Canada

Canada’s Air Passenger Protection Regulations cover flights to, from, and within Canada, including connections. The Canadian Transportation Agency says the regulations set minimum standards of treatment and, in some circumstances, compensation. For a cancellation or lengthy delay caused by a situation outside the airline’s control that prevents it from completing the trip within a reasonable time, the Agency describes a refund or rebooking choice under provisions in force since 8 September 2022. Check the Agency’s current guidance for the specific circumstances and remedy.

United States and other countries

The US Department of Transportation publishes consumer-protection resources, passenger-rights summaries, rulemaking updates, and enforcement notices. The available general guidance does not establish a complete route-and-carrier coverage test for every US-linked international flight. Check the current DOT Air Consumer resources and the rules of any other relevant jurisdiction instead of assuming a particular compensation or coverage rule applies.

The UK, EU, and Canadian examples do not determine the law for a flight through another country. For other jurisdictions, use ICAO’s database to find official material, then confirm the applicable rule with that country’s regulator.

3. Identify which problem each rule covers

Passenger protections can overlap, but they do not all provide the same remedy. Check the rule for the problem you might face rather than treating “passenger rights” as one universal benefit.

  • Delay, cancellation, or denied boarding: Regional or national rules may provide care, a refund, rerouting, or fixed compensation, subject to their coverage and eligibility conditions.
  • Baggage or injury: The Montreal Convention is an international carrier-liability framework. ICAO describes it as addressing qualifying passenger death or bodily injury, loss, destruction, or damage to checked baggage while it is in the carrier’s charge, and damage occasioned by delay. It is not the same thing as a fixed regional cancellation-compensation schedule.
  • Accessibility: Check the rules of the relevant jurisdiction and arrange assistance with the airline or airport before travel. UK guidance, for example, describes free assistance and carriage of medical equipment and up to two pieces of mobility equipment under UK rules; do not assume those exact entitlements apply elsewhere.
  • Package travel and insurance: Package-travel protections and optional insurance may address different losses or obligations from flight-disruption rules. Read the applicable package terms and insurance policy; insurance does not establish which statutory flight rights apply.
  • Fare and baggage conditions: Read the carrier’s terms and booking information for baggage, seat selection, and other charges. GOV.UK says booking information should clearly explain travel conditions and mandatory charges, as well as optional charges such as baggage and seat selection.

4. Save the rules and prepare a claim record

Before departure, save a screenshot or PDF of the relevant official guidance, legislation or claim page, and regulator contact details alongside your itinerary. Note the date you checked the information, especially where the law is changing.

If disruption occurs, preserve records that show what happened, when it happened, what the airline offered, and what you spent because of it. Useful records include:

  • Booking confirmation, ticket, boarding passes, and any revised itinerary.
  • Airline texts, emails, app notifications, and written explanations of the disruption or offered remedy.
  • Receipts for necessary expenses and notes of conversations, including dates and staff or case-reference details where available.
  • Baggage tags and photos of damaged bags or belongings.

If baggage is missing or damaged

Report a missing or damaged bag to the airline at the destination airport. For delayed baggage, provide the baggage-tag information and keep receipts for essential purchases. GOV.UK’s accessed guide says a written claim is required for loss or damage and gives a seven-day deadline for damage claims. Confirm the current deadline and requirements with the airline and relevant authority before acting, since claim time limits matter.

5. Use the complaint route in the right order

  1. Contact the airline first. Use its formal complaint or claim channel, describe the flight and disruption, state the remedy you are seeking, and attach relevant records. Keep a copy of your submission and any response.
  2. Escalate through the applicable official route. If the airline does not resolve the issue, follow the regulator’s complaint guidance for the jurisdiction that covers your flight. In the UK, GOV.UK says unresolved complaints may, depending on the case and airline membership, go to an alternative dispute-resolution provider, the Civil Aviation Authority, or the Consumer Council for Northern Ireland for relevant flights.
  3. Check deadlines and eligibility before escalation. Follow the official instructions for the relevant claim type; a baggage claim, disruption complaint, and liability claim may have different requirements.

The European Commission’s air-passenger-rights information links to Regulation 261/2004, Montreal Convention and related carrier-liability rules, reduced-mobility legislation, relevant case law, and national enforcement bodies. For a practical EU claim path, start with Your Europe and follow its guidance for the relevant country. The Canadian Transportation Agency likewise provides information on passenger rights and complaints.

A quick pre-flight check

  1. Write down every leg, airport and country, connection, marketing airline, and operating airline.
  2. Check official passenger-rights guidance for each relevant jurisdiction; use ICAO’s database only as a starting point.
  3. Look up the relevant rules for delay, cancellation, denied boarding, baggage, accessibility, and complaint routes.
  4. Read fare, baggage, and package conditions, and arrange any required accessibility assistance with the airline or airport.
  5. Save the official guidance and claim links with your booking records so they are available if your plans change.
