A delayed flight does not come with one universal payout. The route, operating carrier, final-arrival delay, and your decision to travel usually control the result.
US passengers usually have a refund question, not a fixed federal cash claim. A qualifying EU or UK trip may also bring fixed compensation when you reach the final destination at least three hours late.
Your choice after the delay matters. If you fly, refund rights can change; EU and UK compensation may still be available. Keep those claims separate.
Start with the route and operating carrier
Check the operating carrier before you claim. Your ticket may show a marketing partner, while another airline actually flew the aircraft.
Look at each leg of a connection. The applicable rule can change midway through one itinerary.
| System | Starting coverage | Main issue |
|---|---|---|
| US DOT | Covered air travel to, from, or within the United States | A significant delay can create a refund right if you decline the alternative |
| EU261 | A flight leaving an EU airport on any airline, or an inbound flight from outside the EU on an EU airline | Care, rerouting or a refund, and sometimes fixed compensation |
| UK261 | A flight leaving a UK airport on any airline; some inbound routes depend on the carrier and departure country | Care, rerouting or a refund, and sometimes fixed compensation |
| Canada APPR | Flights covered by Canada's passenger protection rules | Eligibility depends on the cause, carrier size, and delay length |
A round trip can fall under different systems. Nationality normally does not decide EU or UK coverage. Check each leg of a connection.
US flight delay rules: usually a refund, not compensation
US federal rules generally point to a refund, not a delay payout. Under the Department of Transportation's significant-change refund rule, you usually must reject the alternative and decide not to travel.
| Trip type | Significant arrival delay used for the federal refund rule | Likely result |
|---|---|---|
| Domestic itinerary | 3 hours or more | Refund if you do not accept the alternative |
| International itinerary | 6 hours or more | Refund if you do not accept the alternative |
These are refund thresholds. They do not create cash compensation.
Board a flight that arrives three hours late, and federal law does not require a USD 600 check simply because the flight was delayed. Other options may exist, including an airline customer service promise, travel insurance, a credit card benefit, or another country's law on a different flight leg. Those are separate from the DOT refund.
When the federal refund rule applies, the money should return to the original form of payment. A credit card refund is generally due within seven business days. If the airline cancels the flight and you decline rebooking, the same basic refund choice applies.
Meals and hotels follow a different track. US federal law does not create one universal meal or hotel entitlement for every delayed flight. Airlines covered by 14 CFR 259.5 must publish customer service plans, and the DOT can enforce the promises those plans contain, so read the policy for the disruption.
Write to the airline first if it refuses a refund that appears to qualify. You can then submit a DOT complaint. That may support enforcement, but it is not the same as a private damages award.
EU261 separates care, refunds, and cash
EU261 divides a disruption into separate rights. The European Commission's air passenger rights guidance is a useful place to check route coverage.
A flight leaving an EU airport can be covered whatever the airline's nationality. An inbound flight from outside the EU can also fall under EU261 when an EU airline operates it.
For a connection on one reservation, the relevant delay is usually the delay at the final destination. Separate tickets can produce a different result.
Fixed EU compensation amounts
Cash compensation normally requires arrival at the final destination at least three hours late, with no qualifying extraordinary circumstance.
| Route distance | Fixed amount if eligible |
|---|---|
| Up to 1,500 km | EUR 250 |
| 1,500 to 3,500 km | EUR 400 |
| More than 3,500 km | EUR 600 |
Distance, not ticket price, sets the amount. On some long-haul rerouting cases, EUR 600 can be reduced to EUR 300 when you reach the final destination less than four hours late.
Care starts earlier than compensation.
Care during a long wait
The airline's care duty generally starts after these departure delays:
| Route distance | Departure delay that usually triggers care |
|---|---|
| Up to 1,500 km | 2 hours |
| EU flights over 1,500 km, and other flights from 1,500 to 3,500 km | 3 hours |
| More than 3,500 km | 4 hours |
Care can cover meals, refreshments, and communications. An overnight delay can also mean a hotel and transport between the airport and hotel.
Once the departure delay reaches five hours, you may choose a refund instead of continuing the journey. If the airline does not provide care, pay only for reasonable alternatives and keep itemized receipts.
When extraordinary circumstances matter
Severe weather or air traffic restrictions may qualify as extraordinary circumstances. Airport closures and strikes by people outside the airline may qualify too.
Those events can remove the fixed compensation payment. They do not normally erase the right to care or rerouting.
Routine technical defects and ordinary airline staffing or maintenance problems are not automatically extraordinary. Ask the airline to identify the specific event, when it occurred, and how it caused your delay. The EU passenger rights FAQ addresses several of these disputes.
There is no single EU-wide claim deadline. National law can control the time limit, so file promptly rather than relying on an online calculator or comment.
UK261 uses similar rules with GBP amounts
UK261 broadly retains the EU-style structure for covered flights. A qualifying arrival delay is generally three hours or more, unless an extraordinary circumstance caused it.
| Route distance | Arrival delay | Amount per passenger |
|---|---|---|
| Under 1,500 km | 3 hours or more | GBP 220 |
| 1,500 to 3,500 km | 3 hours or more | GBP 350 |
| More than 3,500 km | 3 to 4 hours | GBP 260 |
| More than 3,500 km | More than 4 hours | GBP 520 |
UK261 generally covers flights leaving a UK airport on any airline. Inbound coverage depends on the departure country and operating carrier. A flight leaving the EU may instead be governed by EU261, so check the leg rather than the booking as a whole.
Ryanair, easyJet, and other airlines use their own claim forms. An airline's form does not replace a statutory UK or EU right. The UK Civil Aviation Authority's delay guidance sets out the main compensation and care rules.
Claim deadlines can depend on the UK nation and the route used to enforce the claim. An airline's internal form deadline is not automatically the legal deadline, but waiting can make the evidence harder to prove. Submit the claim soon and save the response.
Canada and baggage claims follow different tracks
Canada's Air Passenger Protection Regulations are separate from US and European rules. For large airlines, a qualifying delay of at least three hours can lead to compensation of up to CAD 1,000, but the cause, carrier size, safety issues, and the airline's control over the disruption all matter.
Start with the airline. If it doesn't resolve the complaint, the Canadian Transportation Agency may provide a further complaint route. Don't transfer EU thresholds to a Canadian itinerary.
A delayed bag is a separate claim. An international baggage problem may fall under the Montreal Convention, which has its own liability limits and notice deadlines. Report the problem at the airport, obtain a mishandled-baggage report, and keep receipts for necessary purchases.
Neither IATA nor an airline's global policy creates one worldwide delay payout. The departure country and operating carrier still drive the main passenger-rights analysis.
A flight delay calculator needs more than minutes
Delay minutes alone won't answer the claim. A useful estimate needs the route, carrier, final arrival, and what you did after the disruption.
| Information to collect | Why it matters |
|---|---|
| Departure and arrival airports | Identifies the likely legal system |
| Operating carrier | Can determine EU or UK coverage |
| Scheduled and actual final arrival | Measures the relevant delay |
| One reservation or separate tickets | Affects connection analysis |
| Delay reason and airline messages | Helps assess extraordinary circumstances |
| Travel choice and receipts | Separates refund, compensation, and care claims |
Use the actual final arrival, not only the departure delay. For EU and UK disputes, arrival is generally tied to when passengers can leave the aircraft, not simply when the wheels touch the runway.
Treat a calculator's result as an estimate. It isn't an admission by the airline or a legal finding.
How to file a stronger delay claim
A clear timeline usually helps more than a long complaint. Work through these steps:
- Save the evidence. Keep the booking confirmation, boarding pass, delay notices, screenshots, and airline messages. Download them before the airline app removes old trip information.
- Build a short timeline. Record the scheduled departure and arrival, actual departure and arrival, connection details, and the explanation the airline gave you.
- Request care at the airport. Ask for meals, refreshments, a hotel, or transport when the applicable rules require them. If you pay yourself, choose a reasonable option and keep the itemized receipt.
- Use the airline's official channel. Include the flight number, date, route, operating carrier, scheduled and actual final arrival, and the remedy you want. Say whether you are requesting a refund, fixed compensation, care expenses, or more than one remedy.
- Challenge a vague denial. If the airline cites weather, staffing, or a technical problem, ask for the specific event, its duration, and its direct effect on the flight. Attach your timeline and relevant receipts.
- Escalate through the correct route. In the US, use a DOT complaint for an unresolved refund issue. In the EU, the relevant national enforcement body or a European Consumer Centre may help with a cross-border dispute. In the UK, check the CAA-approved alternative dispute resolution route. In Canada, consider the CTA process after contacting the airline.
A claims company is optional. Filing directly first lets you see the airline's position without giving up part of any eventual payment.
Common assumptions that fail
Three hours in the US does not equal a cash award. A departure delay alone does not settle an EU or UK compensation claim, because cash usually depends on final arrival. A booking site does not decide which airline operated the flight, and a voucher does not automatically replace a statutory cash remedy.
Four details that often change the outcome
You flew after the delay
In the US, boarding and completing the flight usually ends the federal refund claim for the used ticket. Under EU or UK rules, you may still qualify for fixed compensation if the final-arrival delay and cause meet the requirements.
The airline blamed weather
Weather may be extraordinary, but the label alone tells you little. Ask for the specific weather or air traffic event and keep any airport notices. Care can still be due while you wait.
The trip came through a travel site
The travel site may have handled payment or rebooking, while the operating carrier handled the aircraft and delay explanation, so keep both sets of messages - and, yes, the seller's receipt too. Send the delay claim to the airline and involve the seller if it controls the refund transaction.
The airline offered a voucher
Read the offer before accepting it. If you prefer money, ask whether accepting the voucher changes the remedy the airline is offering under the applicable rule.
Your next move
Open the booking confirmation and note the operating carrier and scheduled arrival. Add the actual final arrival, the airline's stated reason, and any care receipts.
Then submit the claim through the correct airline channel. If the response stays vague, use the regulator or dispute-resolution route for the jurisdiction covering that flight leg.
