A five-hour delay doesn't automatically mean a U.S. airline owes you cash. Federal U.S. rules generally require a ticket refund when an airline cancels or significantly changes a flight and you reject the alternative instead of traveling. They don't set compensation for an ordinary late arrival.

EU261 and UK261 work differently. A qualifying passenger who reaches the final destination at least three hours late may be entitled to a fixed payment unless the airline proves an extraordinary circumstance. Meals, hotels, ticket refunds, travel insurance, and fixed compensation are separate remedies, so identify the one you want before sending a claim.

Start with these questions:

Don't copy an EU261 template into a U.S. domestic delay claim. The available remedy may be entirely different.

U.S. flight-delay disputes: what you can actually claim

The U.S. has no general federal law requiring airlines to pay passengers a set amount for arriving late. A mechanical delay, crew problem, or aircraft-rotation issue may be frustrating, but it doesn't automatically produce USD 250, USD 400, or USD 600.

The key U.S. question is whether you traveled:

• Canceled or significantly changed flight: If you reject the airline's alternative and don't travel, you can generally request a refund under U.S. Department of Transportation rules.
• Delayed flight that you completed: A federal ticket refund usually isn't available solely because you arrived late. Check the airline's contract, disruption policy, travel insurance, and credit-card benefits for possible expense coverage.
• Meals or hotel: Some airlines promise meals, hotel rooms, or ground transportation for disruptions within the airline's control. Those commitments vary by airline and aren't a universal federal compensation schedule.
• Voucher or miles: An airline may offer a goodwill credit, but read the conditions before accepting it as a full settlement. If a refund is required, the airline generally shouldn't replace it with a voucher unless you agree to that form of payment.

The DOT's Air Consumer portal and refund guidance are useful when an airline refuses a refund that should be due. A DOT complaint can document a possible violation, but it isn't a court judgment awarding compensation for inconvenience.

When a U.S. delay becomes a refund issue

A significant change can include, among other situations:

• An arrival at least three hours later for a domestic itinerary.
• An arrival at least six hours later for an international itinerary.
• A change to a different departure or arrival airport.
• An added connection or another material change to the itinerary.

These are examples of the DOT's significant-change standards, not a promise of cash for a late arrival. If you accept the new flight and complete the trip, record that clearly. A request for reimbursement of reasonable expenses or a goodwill payment is different from a demand for a full fare refund.

EU261 and UK261 delayed-flight compensation

EU261 generally covers:

• Flights departing from an airport in the EU, Iceland, Norway, or Switzerland, regardless of the airline.
• Flights arriving in one of those countries from outside them when operated by an EU, Icelandic, Norwegian, or Swiss carrier.

UK261 generally covers:

• Flights departing from a UK airport, regardless of the airline.
• Flights arriving in the UK from outside the UK when operated by an eligible UK carrier.

The exact scope can be more complicated for routes between the EU and the UK, codeshares, and connecting itineraries. A journey can be covered by one regime, both regimes in limited circumstances, or neither. Passengers can't recover the same compensation twice.

For a qualifying arrival delay of at least three hours, the standard amounts are:

These amounts are per eligible passenger. The airline may avoid fixed compensation by proving an extraordinary circumstance and showing that reasonable measures couldn't have prevented the delay.

For a flight over 3,500 km, the amount can be reduced by 50% when the arrival delay falls in the three-to-four-hour band. That produces EUR 300 under EU261 or GBP 260 under UK261. A 50% reduction may also apply after rerouting when the replacement flight arrives within the applicable statutory limit: two hours for the shortest distance category, three hours for the middle category, or four hours for a longer flight. The route distance, final arrival time, and rebooking details all matter.

The European Parliament's passenger-rights factsheet and European Consumer Centre guidance provide useful background. For UK flights, the Civil Aviation Authority's delays guidance explains the principal UK261 amounts and care rights.

Compensation is separate from care

EU and UK rules can provide care while you wait, even when the cause defeats a fixed-compensation claim. Depending on the route and waiting time, care can include:

• Reasonable meals and refreshments.
• Two communications, such as calls or emails.
• Hotel accommodation when an overnight stay is necessary.
• Transportation between the airport and hotel.

The usual care thresholds are two hours for flights up to 1,500 km, three hours for certain medium-distance flights, and four hours for longer flights. If the airline doesn't provide the promised care, buy reasonable items rather than luxury alternatives and keep itemized receipts.

If the departure delay reaches at least five hours and you decide not to continue, EU and UK rules may provide a refund for the unused journey. That reimbursement right is separate from fixed compensation. Accepting a replacement flight also doesn't automatically waive a possible compensation claim if the final arrival delay and other conditions meet the applicable rule.

Common denial reasons and practical responses

"The delay was caused by a technical problem"

An ordinary technical defect discovered during normal airline operations isn't automatically an extraordinary circumstance under EU261 or UK261. In Wallentin-Hermann v Alitalia, C-549/07, and van der Lans v KLM, C-257/14, the Court of Justice of the European Union treated many unexpected technical problems as part of an airline's normal activity.

That doesn't mean every maintenance event qualifies. An airline may rely on a genuinely external event, such as sabotage or a defect identified by the manufacturer, if it can show the event caused the delay and that reasonable measures were taken.

Ask the airline to identify the specific event rather than accepting "technical issue" as a complete explanation.

"The weather was extraordinary"

Severe weather can be an extraordinary circumstance when it directly prevents the flight from operating safely. The airline still needs to connect the weather to your delay. A later staffing, maintenance, or aircraft-rotation problem may require separate analysis.

Weather usually doesn't remove the EU or UK duty to provide care. Keep receipts even if the airline says fixed compensation isn't payable.

"Air traffic control caused the delay"

A genuine air-traffic-control restriction may be outside the airline's control. Ask for the affected flight segment, approximate time, and explanation of how the restriction caused your final delay. The airline's own late aircraft or crew shortage shouldn't be treated as an ATC event without supporting facts.

"You accepted the rebooking"

Under EU261 and UK261, accepting an alternative flight doesn't by itself waive a possible compensation claim. Compare the original scheduled arrival with your actual arrival at the final destination.

In the U.S., accepting and using an alternative flight usually means you can't later demand a full refund merely because the original flight was delayed. You may still have a claim under an airline promise, insurance policy, or card benefit.

"The travel agent sold the ticket"

For EU or UK fixed compensation, identify the airline that operated the disrupted flight. A travel agency may be relevant to a ticket refund or booking error, but it usually doesn't replace the operating carrier as the first destination for a flight-delay compensation claim.

Real legal cases that clarify delayed-flight disputes

These are court precedents, not guarantees that every passenger with similar facts will win.

• Folkerts v Air France, C-11/11: Compensation can depend on the arrival delay at the final destination of a single-booking connection. An initial segment delayed by less than three hours can still lead to compensation when the passenger reaches the final destination three or more hours late.
• Germanwings v Henning, C-452/13: For EU261 purposes, arrival is generally measured when at least one aircraft door opens and passengers can leave, not when the aircraft touches down.
• Wallentin-Hermann v Alitalia, C-549/07: A technical problem arising from normal airline operations isn't extraordinary merely because it was unexpected.
• van der Lans v KLM, C-257/14: An unexpected technical failure doesn't automatically excuse fixed compensation.
• Pešková and Peška v Travel Service, C-315/15: A bird strike can be extraordinary, but the airline must still consider reasonable measures and the precise cause of the resulting delay.
• McDonagh v Ryanair, C-12/11: Extraordinary circumstances can excuse fixed compensation, but they don't eliminate the duty to provide necessary care during a prolonged disruption.

Use the case name or number to explain your position, but keep the claim focused on your route, arrival time, cause, and evidence.

Worked delayed-flight examples

Example 1: Five-hour United delay within the U.S.

A passenger completes a domestic United itinerary five hours late after a mechanical problem.

There is no automatic federal payment for the late arrival and no automatic refund simply because the passenger traveled. The passenger should check the airline's written commitments, submit reasonable documented expenses if the policy covers them, and review any qualifying travel-insurance or credit-card trip-delay benefit.

A DOT complaint may be appropriate if the airline refuses a refund triggered by a cancellation or significant change, but it isn't a claim for a fixed delay payment.

Example 2: Three-hour, 45-minute Amsterdam delay

A passenger departs Amsterdam and reaches the destination three hours and 45 minutes late after an ordinary technical problem. If the route is within 1,500 km and no extraordinary circumstance is established, the likely EU261 amount is EUR 250 per eligible passenger.

The passenger should also claim reasonable meals or other care expenses that the airline failed to provide. The technical explanation alone isn't enough to reject the compensation claim.

Example 3: Four-hour, 10-minute Paris-to-New York delay

A passenger departs Paris and reaches New York four hours and 10 minutes late because of a routine technical fault. Because the flight departs the EU, EU261 generally applies regardless of the operating airline. Assuming the distance exceeds 3,500 km and the airline can't establish an extraordinary circumstance, the standard amount is EUR 600 per passenger.

A delay in the three-to-four-hour band can lead to a 50% reduction, so record the exact arrival time rather than relying on a rounded airline notification.

Example 4: Glasgow-to-Amsterdam delay

A passenger departs the UK for Amsterdam and arrives three hours and 20 minutes late. If the route is under 1,500 km and the airline can't prove an extraordinary circumstance, UK261 may provide GBP 220 per passenger.

If severe weather caused the delay, fixed compensation may not be payable, but the passenger can still ask for the meals, refreshments, or overnight accommodation required by the care rules.

Build a stronger claim before you send it

Collect these records:

1. Booking confirmation, ticket number, and boarding passes.
2. Flight number, operating carrier, scheduled arrival, and actual arrival.
3. Proof of the final arrival time, such as an airline message or airport record.
4. Screenshots of delay notices, gate changes, and rebooking messages.
5. The airline's stated reason for the disruption.
6. Receipts for reasonable meals, hotel rooms, local transport, and communications.
7. Copies of every complaint, response, and promised reimbursement.
8. Travel-insurance or credit-card benefit terms if you're making a separate claim.

For EU or UK purposes, the relevant arrival time may be when a usable aircraft door opens, not when the wheels touch down. Keep the airline's arrival record and any other time evidence.

A baggage report or property irregularity report number is for a baggage complaint. It doesn't replace evidence for a flight-delay claim.

For a connecting itinerary, keep both boarding passes and confirm whether every segment was on one reservation. For a codeshare, note both the marketing airline and the operating airline.

Step-by-step dispute process

1. Calculate the correct remedy

Don't start with a dollar amount. First decide whether you're requesting:

• A U.S. refund after a cancellation or significant change.
• EU261 or UK261 fixed compensation.
• Reimbursement for care expenses.
• Reimbursement under an airline policy.
• A travel-insurance or credit-card benefit.

One disruption can support more than one of these, but each has different conditions. Don't submit the same expense twice to different programs.

2. Send the claim to the right party

For EU or UK compensation, start with the airline that operated the delayed flight. Include every eligible passenger, the booking reference, and the operating carrier.

For a U.S. refund, use the airline or ticket seller's refund process and state whether you rejected the replacement itinerary. Save the confirmation number.

Submit promptly. Internal expense-submission deadlines can differ from legal limitation periods, and court deadlines are set by the applicable national or state law. There is no universal "two-year EU deadline" for every claim.

3. Challenge a vague rejection

If the airline says "weather," "ATC," or "technical issue," ask it to state:

• The exact event it relies on.
• Which flight segment was affected.
• How that event caused your final arrival delay.
• What reasonable measures it took to avoid or reduce the delay.

Keep the follow-up focused. Leave out unrelated complaints, unsupported estimates, and social-media claims.

4. Escalate through the correct route

• United States: File a complaint with the DOT Air Consumer portal if the airline appears to have violated refund rules or another federal requirement. A DOT complaint can support regulatory review, but it isn't a court order awarding compensation for inconvenience. Use a state consumer-protection office or court only when appropriate for the specific dispute.
• European Union: After contacting the airline, consider the relevant national enforcement body, an approved alternative-dispute scheme where available, or the appropriate court. The European Consumer Centre can help explain cross-border options.
• United Kingdom: Check whether the airline belongs to an approved aviation ADR scheme. The CAA provides passenger guidance, but it generally doesn't act as a court awarding every individual compensation claim.

Before filing in court, check the applicable limitation period, court fees, service rules, and whether a pre-action letter is required. A high-value or disputed cross-border claim may justify local legal guidance.

Delayed-flight dispute templates

EU261 or UK261 initial claim

Subject: Flight-delay compensation claim - [flight number] on [date]

I was a passenger on [flight number] from [departure airport] to [final destination] on [date]. The scheduled arrival time was [time], and the actual arrival time was [time]. The itinerary was booked under reference [reference]. The operating carrier was [airline].

I am requesting [EUR 250, EUR 400, or EUR 600 / GBP 220, GBP 350, or GBP 520] per eligible passenger under [EU261 / UK261], subject to the applicable route-distance and delay rules. The reason given for the delay was [airline's stated reason].

Please also reimburse the attached reasonable expenses for meals, accommodation, or transport that were necessary because care wasn't provided.

If you reject this request, please identify the specific extraordinary circumstance, explain its causal connection to the delay, and describe the reasonable measures taken to avoid the delay. Please send your written decision and the payment method available for this claim.

Passenger name: [name]
Booking reference: [reference]
Contact details: [email and mailing address]

Response to an unclear denial

Subject: Request for details about rejected delay claim - [flight number]

Thank you for your response dated [date]. You attributed the delay to [weather, ATC, technical issue, or other reason], but the response doesn't explain which event affected the flight or how it caused the arrival delay of [time].

Please provide the specific factual basis for the decision, including the affected flight segment and the measures taken to prevent or reduce the delay. If the reason was an ordinary technical problem, please reconsider the claim under the applicable EU261 or UK261 rules and relevant court decisions.

I reserve my rights regarding fixed compensation and documented care expenses. Please treat this message as a request for a reasoned review.

U.S. refund request after cancellation or significant change

Subject: Refund request for canceled or significantly changed flight - [flight number]

My itinerary [booking reference] for [flight number] on [date] was [canceled / significantly changed]. The replacement itinerary would arrive [number] hours later or would otherwise materially change the trip. I didn't accept the alternative transportation and didn't use the ticket.

I am requesting a refund for the unused transportation and eligible taxes or fees to the original form of payment under applicable U.S. DOT refund rules. Please don't issue travel credit or miles instead unless I expressly agree to that option.

Attached are my confirmation, the original itinerary, the change notice, and proof that I didn't use the replacement flight. Please confirm receipt and provide the refund status in writing.

If you completed a replacement flight, don't use this template to demand a full fare refund merely because the arrival was late. Request only the reimbursement or benefit supported by the airline's policy, your insurance, or your card's terms.

Frequently asked questions

Can I claim compensation for a U.S. flight delayed five hours?

Usually not under a federal fixed-compensation rule. You may have a refund right if the flight was canceled or significantly changed and you declined to travel, or an expense claim under an airline policy, insurance policy, or card benefit.

Does a mechanical problem qualify for EU261 compensation?

Often, an ordinary technical defect isn't extraordinary under EU case law. The result depends on the specific event and whether it caused the delay. Ask the airline for a reasoned explanation instead of relying on a generic delay code.

Does bad weather always defeat a claim?

No. Severe weather may defeat fixed compensation when it directly caused the delay, but the airline still owes required care under EU or UK rules. A later, independent operational problem may need separate analysis.

Can I claim after accepting a new flight?

Under EU261 or UK261, possibly. Compare your actual arrival at the final destination with the original scheduled arrival. In the U.S., accepting and taking the replacement flight generally ends the ticket-refund route for that disruption.

What if the airline never explains the denial?

Send a short written follow-up requesting the exact cause, causal connection, and steps taken to limit the delay. Then use the relevant regulator, ADR process, or court route for the jurisdiction that governs the flight.

How long do I have to file?

The deadline depends on the country and the type of claim. Airline submission windows, insurance deadlines, and court limitation periods aren't interchangeable. File promptly and verify the local deadline before waiting for a final airline response.
