Whether a delayed flight pays anything depends on the route, the operating carrier, and whether you completed the trip. In the United States, a late arrival alone usually does not create a federal cash payment. A covered significant change can support a DOT refund if you reject the replacement travel and do not fly. EU261 can provide fixed amounts of EUR 250, EUR 400, or EUR 600, while other international claims generally require proof of actual financial loss.
Start with the itinerary. The alert on your phone is not the rule. The same delay can mean no federal payment, a ticket refund, or fixed European compensation.
Identify the rule before contacting the airline
First, identify the framework. The airline's logo isn't enough.
| Itinerary or problem | Main framework | What it may provide |
|---|---|---|
| U.S. domestic trip or flight to or from the United States | U.S. Department of Transportation refund rules | A ticket refund after a qualifying significant delay or change, if you reject alternative travel and do not fly |
| Flight leaving an EU airport | EU261 | Fixed compensation, care, rerouting, or reimbursement, depending on the facts |
| Flight entering the EU from outside the EU on an EU carrier | EU261 | Similar EU261 rights |
| Flight covered by UK routes or carriers | UK261 | A separate regime with similar concepts, but different route and deadline questions |
| International carriage between countries covered by the treaty | Montreal Convention | Possible recovery of proven financial damage, rather than a fixed delay payment |
Canada has its own passenger-protection system. Don't apply EU or U.S. figures to a Canadian itinerary without checking the Canadian rules.
What a delayed flight usually means in the United States
U.S. consumers often call every remedy compensation. A refund and compensation aren't the same thing.
For refund purposes, the DOT significant-change standard uses these arrival thresholds:
| Itinerary | Significant delay threshold | Main condition |
|---|---|---|
| Domestic U.S. itinerary | At least 3 hours later at arrival | You do not accept the changed transportation and do not travel |
| International itinerary | At least 6 hours later at arrival | You do not accept the changed transportation and do not travel |
These are refund thresholds. They are not guaranteed inconvenience payments.
The refund generally covers unused transportation and qualifying services the airline did not provide. To get it, you must reject the changed transportation and stay off the replacement flight.
Read the DOT refund information and its automatic refund rule guidance before accepting a voucher. Refunds generally go to the original form of payment unless you choose another option. Credit-card refunds generally must be processed within seven business days; other payment methods generally have a 20-calendar-day deadline.
Weather or air-traffic problems can still satisfy the refund rule if the delay is significant and you decline the changed travel. The airline usually does not need to have caused the event for this refund question.
If you take the delayed flight and reach your destination, the DOT refund rule usually does not turn that completed trip into a cash compensation claim. Check the carrier's customer-service commitments instead. Travel insurance and credit-card benefits may also matter.
EU261 compensation for a delayed flight
EU261 follows the route and operating carrier. Your nationality doesn't decide coverage.
A flight departing from an EU airport is generally covered, regardless of the airline. A flight arriving in the EU from outside the EU is generally covered when an EU carrier operates it. A UK departure or qualifying UK carrier flight may fall under UK261 instead.
The official EU261 regulation and the Your Europe passenger-rights page set out the main framework.
| Covered flight distance | Fixed compensation when final arrival is at least 3 hours late |
|---|---|
| Up to 1,500 km | EUR 250 |
| More than 1,500 km within the EU, or other flights from 1,500 km to 3,500 km | EUR 400 |
| Other covered flights | EUR 600 |
The amount doesn't depend on your fare or lost wages. The airline can avoid fixed compensation if it proves that extraordinary circumstances caused the delay.
Under EU261, the three-hour test concerns arrival at the final destination. A missed connection on one reservation is therefore usually assessed by the final arrival time, not just the delay on the first flight. Separate tickets are usually assessed separately.
Rerouting can reduce the compensation in some cases. Check the actual final arrival time before assuming the full table amount applies.
Care, rerouting, and reimbursement under EU261
Fixed compensation is only one EU261 remedy. Care is separate.
Depending on the distance and departure delay, the airline may need to provide reasonable meals and refreshments. If the delay requires an overnight stay, hotel accommodation and transport between the airport and hotel may also be required.
A departure delay of at least five hours can give you a choice between continuing the journey and receiving reimbursement for the unused part of the ticket. It isn't a blanket percentage refund for every long delay.
If the airline doesn't provide required care, keep receipts for reasonable expenses. Explain what was missing when you file the claim.
When an airline can deny fixed EU compensation
An airline cannot end the analysis with a one-word label.
Severe weather, air-traffic management decisions, security risks, and political instability may qualify as extraordinary circumstances. An ordinary technical fault, routine maintenance problem, or internal crew-planning issue is not automatically extraordinary.
Ask the airline to identify the exact event that affected your flight. It should also explain why the event could not have been avoided with all reasonable measures.
Turns out, the cause can block fixed compensation without removing the right to care. A weather delay may still leave you with a claim for reasonable meals or a hotel.
Ryanair, easyJet, and other airline claims
On a qualifying EU261 flight, the carrier's brand does not change the statutory compensation bands. Ryanair and easyJet do not have lower EU261 amounts.
The operating carrier matters. If a booking site sold the ticket, copy it on your correspondence, but start with the airline that operated the delayed flight.
Send the claim through the carrier's official channel. Include the flight number, travel date, departure airport, final arrival airport, scheduled and actual arrival times, booking reference, and amount requested. State whether the journey was on one reservation.
If the airline rejects the claim because of a technical problem, ask for the specific event rather than accepting a general label. Keep the case number and written response.
What a delay calculator can and cannot tell you
A delay calculator can screen for the likely distance band. It can't decide route coverage or the operating carrier.
It also won't resolve extraordinary circumstances, separate tickets, or the correct final arrival time. Use the table above as a second check.
Thing is, the estimate is only as good as the facts entered. A claimed success rate is not evidence that your claim qualifies. Save the itinerary before relying on the result.
A practical claim workflow
A clean record beats a long story.
- Save the booking documents. Keep the confirmation, boarding passes, ticket receipt, rebooking messages, and airline emails.
- Build a timeline. Record the scheduled departure and arrival, actual departure, final arrival, gate announcements, and messages received during the delay.
- Identify the operating carrier. Check whether the trip used one reservation, a codeshare, or separate tickets.
- Choose the remedy. Ask for a U.S. refund, EU261 compensation, reimbursement of required care, or documented international losses. Don't combine unrelated requests.
- File in writing. Use the airline's official claim or customer-service channel. Name the rule, describe the facts, and request a specific amount.
- Challenge a vague denial. Ask whether the airline relies on extraordinary circumstances and request the precise cause affecting your flight.
- Escalate carefully. For an EU itinerary, use the enforcement or alternative-dispute route identified for the relevant country. For a U.S. refund issue, a DOT complaint can create a regulatory record. A complaint is not the same as a court filing.
International flights and the Montreal Convention
Outside the U.S. and EU systems, no single worldwide three-hour payment rule applies.
The Montreal Convention may apply to international carriage between countries covered by the treaty. A claim under it concerns actual damage caused by the delay, not a preset award. A reasonable hotel bill, ground transportation cost, or other necessary expense may be relevant.
You must connect the loss to the delay and support it with records. The carrier may contest the claim if the loss was not proven or if it took the measures reasonably required to avoid the damage.
There is no automatic EUR 600 or USD payment simply because an international flight arrived late. Domestic U.S. flights are ordinarily not Montreal Convention claims.
Travel insurance and card benefits are separate contracts. Check their terms rather than treating them as airline compensation.
Four examples
| Situation | Likely result |
|---|---|
| A domestic U.S. passenger completes a trip and arrives four hours late | No automatic federal delay payment under the DOT refund rule; check separate benefits or policies |
| A domestic U.S. passenger faces a four-hour significant delay, declines the new travel, and does not fly | A refund may be due under the DOT rule, generally to the original payment method |
| A covered EU flight of 2,000 km reaches its final destination 3 hours and 20 minutes late, with no extraordinary circumstance | EUR 400 may be available |
| An international flight arrives eight hours late and causes a USD 350 hotel bill | A documented damages claim may be possible if the Montreal Convention applies; there is no automatic fixed payout |
Deadlines and escalation
Deadlines are not interchangeable. Don't rely on a universal two-year or six-year deadline for every flight claim.
EU261 time limits can depend on national law. UK261 is a separate regime with its own route and deadline questions.
The DOT refund processing deadline is not the same as a deadline for bringing a separate damages claim. Montreal Convention claims have their own treaty time rules. File promptly, then check the applicable country, contract, and court before waiting.
To be honest, an online form is not a substitute for checking the applicable deadline. Keep a copy of the submission, attachments, confirmation number, and rejection.
Mistakes that weaken a claim
At the airport, departure delay is usually the easiest number to see. Under EU261, final arrival delay is often the number that matters.
Passengers also count separate tickets as one journey, contact only the booking site, or accept a voucher before deciding whether a refund is more appropriate. Those choices can change the remedy available.
One airport board can point to three different outcomes: a refund, a fixed EU payment, or a receipt-heavy damages claim. Not neat, but that's the system.
Your next step
Open the booking confirmation now. Write down the operating carrier, departure airport, final destination, scheduled arrival, and actual final arrival. Then match those facts to the rule above and submit one precise request with the supporting records.
