Short answer: You may qualify for a ticket refund, fixed delay compensation, practical care, or more than one of these—but the result depends on the itinerary, operating airline, delay at your final destination, reason for the disruption, and whether you accepted replacement travel or a voucher. There is no single worldwide rule.
This guide covers the United States, European Union, United Kingdom and a high-level Canadian overview. Other countries can apply different thresholds and remedies.

Refund, compensation and care are different remedies
Passengers often use “refund” and “compensation” as if they mean the same payment. They do not. Identify the remedy before contacting the airline.

|---|---|---|
| Refund | Returning money for qualifying unused air travel | You decline a cancelled or significantly changed itinerary instead of taking the offered alternative |
| Compensation | A separate statutory payment for inconvenience or delay | Only where the applicable jurisdiction’s conditions, delay threshold and cause rules are met |
| Care | Immediate assistance while you wait | Meals, communications, lodging or transport under the relevant airline or passenger-rights rules |
| Rerouting | Getting you to your destination on an alternative service | A cancellation or qualifying disruption where the law gives a choice between rerouting and reimbursement |
A refund does not automatically create a right to a cash delay payment, and accepting a replacement flight can affect whether a refund remains available. Conversely, a compensation claim can be separate from the cost of unused travel where the governing rules allow both.
#1 Best Overall
First identify which rules apply
Before calculating a claim, write down the departure airport, final arrival airport, operating carrier, ticketing carrier, each segment, and whether every segment was on one reservation. The airline that sold the ticket may not be the airline that operated the flight. For EU claims, the operating airline is generally the correct first contact.
- United States: flights to, from or within the U.S. are subject to U.S. Department of Transportation (DOT) refund rules.
- European Union: passenger-rights rules cover flights within the EU, flights departing the EU for a non-EU country, and flights arriving in the EU from outside the EU when operated by an EU airline. EU citizenship is not required.
- United Kingdom: UK261 generally covers flights leaving 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.
- Canada: the Air Passenger Protection Regulations (APPR) classify disruptions by whether they were within the airline’s control, within its control but required for safety, or outside its control.
If a journey crosses several regions, more than one regime may appear relevant. Apply the rule connected to the particular flight and operating carrier rather than assuming the country where you bought the ticket controls everything.
United States: when a delayed or cancelled flight must be refunded
Cancellation or significant schedule change
DOT rules provide a refund when an airline cancels a flight and you choose not to travel or accept travel credit, a voucher or another alternative. The reason for the cancellation does not remove that refund right. A refund can also be due after a significant delay or schedule change when you decline the changed itinerary and the alternatives offered.
DOT describes a late-arrival significant change as at least three hours for a domestic itinerary or at least six hours for an international itinerary. Other listed qualifying changes include an early departure of at least three domestic hours or six international hours, a change to a different origin or destination airport, an added connection, or an involuntary downgrade.
What happens if you accept the new flight?
The refund rule generally does not apply if you take the significantly changed flight or another alternative flight. Accepting travel credit can also move the transaction away from a cash-refund claim. Read the airline’s offer carefully and state in writing whether you reject the changed travel and request a refund.

Refund timing
For a qualifying credit-card purchase, DOT says the refund is due within seven business days after rejection of the alternative. For other payment methods, the stated period is 20 calendar days. The DOT page also gives timing rules tied to the departure of a changed or alternative flight when a passenger does not respond to an offer and does not fly; keep the notice and your response so the dates can be established.
Does the U.S. pay compensation for an ordinary delay?
The U.S. does not promise a universal cash payment for every late arrival, and there is no automatic federal hotel entitlement for every ordinary delay. The DOT dashboard records the meals, lodging and other services an airline has publicly committed to provide for controllable disruptions. DOT can hold an airline to that stated commitment, but those service commitments are separate from the right to a refund.

Who is covered?
EU passenger-rights rules cover an intra-EU flight, a flight departing an EU airport for a non-EU destination, or a flight arriving in the EU from outside the EU when the operating carrier is an EU airline. A passenger need not hold EU citizenship.
Three-hour final-arrival test
For a delay, the European Commission’s FAQ says arrival at the final destination at least three hours late may qualify for fixed compensation when extraordinary circumstances did not cause the disruption. The relevant measurement is arrival at the final destination, not merely the departure delay. If flights were on one reservation, a missed connection can qualify based on the delay at the final destination.
Cancellation choices and care
For a cancellation, passengers generally have a choice between reimbursement and rerouting, together with assistance while waiting where the regulation requires it. Compensation can depend on how much notice the airline gave and on the cause. Care and rerouting or reimbursement are separate questions from the fixed compensation test.
Possible fixed amounts
| Route distance category | Possible amount | Attribution and qualification |
|---|---|---|
| All flights of 1,500 km or less | €250 | Council of the European Union policy summary, accessed 2026; statutory eligibility and the applicable rule version still control |
| Intra-EU flights, or flights between 1,500 km and 3,500 km | €400 | Council of the European Union policy summary, accessed 2026; not an automatic payment |
| All other flights | €600 | Council of the European Union policy summary, accessed 2026; cause, route scope and delay conditions apply |
These are possible statutory amounts, not guarantees. An extraordinary circumstance can block compensation while leaving care or rerouting or refund rights in place.

2026 rule-change caution
On 13 July 2026, the Council of the European Union said: “The updated air passenger rules will enter into force 12 months and 20 days after the publication in the Official Journal.” The publication date was not established here, so do not treat the updated provisions as operative merely because the Council approved them. Check the Official Journal publication and calculate the commencement date before relying on any added right.
United Kingdom: UK261 delay compensation and refunds
When UK261 applies
UK261 covers a flight departing a UK airport on any airline; a flight arriving in the UK on a UK or EU airline; or a flight arriving in the EU on a UK airline.
Care during a qualifying departure delay
The UK Civil Aviation Authority (CAA) says care can include reasonable food and drink, two telephone calls or emails, and overnight accommodation plus transport between the airport and accommodation when an overnight stay is required. If the airline does not provide promised care, keep itemised receipts and ask for reimbursement of reasonable expenses.
Refund after five hours
When a delay exceeds five hours, a passenger can choose not to travel and claim a refund for the unused flights. That choice concerns the unused transportation; it is distinct from any compensation that might be available for the disruption.
Rank #4
Compensation after a three-hour arrival delay
Compensation may be available when you reach the destination airport more than three hours late, subject to extraordinary-circumstance rules. The CAA lists these amounts:
| Flight distance and arrival delay | Amount | Source context |
|---|---|---|
| Under 1,500 km | £220 | CAA guidance accessed 2026; distance-based amount |
| 1,500 km to 3,500 km | £350 | CAA guidance accessed 2026; distance-based amount |
| Over 3,500 km, arriving three to four hours late | £260 | CAA guidance accessed 2026; longest-route amount depends on delay length |
| Over 3,500 km, arriving more than four hours late | £520 | CAA guidance accessed 2026; longest-route amount depends on delay length |
The amounts are not tied to the ticket price. A qualifying cause and route must still be established.
Claim and escalation
Claim directly from the airline first. If its final response is unsatisfactory, or it has taken more than eight weeks to respond, you can use an approved alternative-dispute-resolution provider if the airline participates, or the CAA’s Passenger Advice and Complaints Team (PACT) under the CAA’s stated conditions.
Canada: classify the disruption before claiming
The Canadian Transportation Agency’s APPR overview separates disruptions into three broad categories:
Free tools Windows power users keep installed
One-click scans. No signup required.
- Within the airline’s control: examples include routine maintenance or operational decisions.
- Within the airline’s control but required for safety: a mechanical problem that must be addressed for safe operation is treated differently from routine maintenance.
- Outside the airline’s control: examples include weather that makes safe operation impossible, air-traffic instructions, airport issues, wildlife collisions and certain labour disruptions.
The category affects the airline’s obligations and the available remedy. The current APPR contains detailed conditions and timing rules, but this overview does not establish every current Canadian compensation amount. Do not assume a particular Canadian dollar figure without checking the CTA’s detailed rule for the date, route and disruption category.

How late does a flight have to be to get compensation?
There is no single worldwide threshold. Under the official rules summarized here, the U.S. thresholds of three domestic hours and six international hours concern a refund after a significant change when you decline travel; they are not a universal U.S. compensation trigger. EU guidance uses arrival at the final destination at least three hours late as the usual starting point for compensation, subject to cause and other conditions. UK261 generally uses arrival more than three hours late for compensation, while a delay exceeding five hours gives a choice not to travel and seek a refund for unused flights.
Always measure the delay at the point specified by the applicable rule. A long departure delay can end with a shorter final-arrival delay, and a connection missed on separate tickets may be treated differently from a connection protected on one reservation.
Can you receive both compensation and a refund?
Potentially, but not automatically. A refund pays back unused transportation when you reject a qualifying cancellation or significant change. Compensation is a separate statutory remedy that depends on route, delay, notice and cause. In the EU or UK, a passenger who does not take a cancelled service may have a reimbursement or rerouting right and may also meet a compensation test; the airline can still rely on an applicable extraordinary-circumstance exception. In the U.S., accepting the replacement flight generally removes the significant-change refund route, and ordinary delay compensation is not universally required.
What if the airline says weather caused the delay?
Weather can be an extraordinary or outside-control circumstance under European, UK or Canadian frameworks when it genuinely prevents safe operation, which may defeat fixed compensation. It does not erase every other remedy: care, rerouting or reimbursement can remain available under the applicable rules. In the U.S., the reason does not remove the refund right after a qualifying cancellation or significant change if you decline travel, although it does not create a general cash payment for a normal delay. Ask the airline to identify the specific event and rule it is relying on rather than accepting “weather” as a complete explanation.
How to claim flight delay compensation or a refund
- Map the itinerary. Record every airport, operating carrier, scheduled and actual arrival time, and whether all segments share one booking reference.
- Preserve the paper trail. Keep the confirmation, ticket, itinerary, boarding passes, airline notices, proof of actual final arrival and receipts for reasonable expenses. No single evidence checklist applies universally, so retain anything that shows what the airline offered and what you accepted.
- Choose the remedy. State whether you are rejecting changed travel and requesting a refund, seeking rerouting, claiming care expenses, or requesting statutory compensation. In the U.S., accepting a changed flight or credit can affect the refund route.
- Write to the airline. Include the route, booking reference, flight date, disruption, actual final-arrival time, remedy requested and receipts. Ask the airline to explain the cause if it denies compensation.
- Keep proof of submission. Save the web-form confirmation, email thread and any case number. Record the date by which the airline says it will respond.
- Escalate to the correct authority. In the UK, use ADR or CAA PACT after the CAA’s stated conditions are met. In the EU, contact the national enforcement body for the relevant country. In the U.S., submit an aviation-consumer complaint to DOT. For Canada, use the CTA complaint process after checking the applicable APPR category.
Common mistakes that weaken a claim
- Claiming against the ticket seller when the operating airline handles the passenger-rights obligation.
- Using departure delay instead of final-destination arrival time where the rule requires the latter.
- Accepting a voucher or replacement flight without checking whether that choice changes a refund right.
- Combining separate tickets and assuming a missed connection receives the same treatment as a connection on one reservation.
- Submitting meal or hotel costs without itemised receipts or without showing that the expense was reasonable.
- Assuming a disruption label such as “technical issue” or “weather” automatically decides compensation; the airline should identify the relevant rule and facts.
- Quoting an EU or UK amount without checking the route distance, cause, notice and law in force on the travel date.
Bottom line for a delayed-flight claim
Start with jurisdiction, operating carrier and final-arrival delay. Then separate the question of unused-ticket money from fixed compensation and from care while waiting. Decline unwanted replacement travel before requesting a U.S. or UK refund, document every offer and expense, claim in writing to the airline, and escalate through DOT, the relevant EU enforcement body, UK ADR or PACT, or the CTA as appropriate. A paid claim-assistance service is optional; no service can guarantee eligibility, speed or recovery.
