A delayed flight doesn't automatically create a right to cash. The answer usually turns on four details: where the flight departs or arrives, whether you were waiting at the gate or on the aircraft, why the delay happened, and whether your connecting flights are on one reservation.

Start by preserving the record. Then protect any connection, ask the airline what it will provide, and decide whether you want to continue or seek a refund. EU and UK rules can require meals, hotels, refunds, and fixed compensation. For an ordinary U.S. delay, federal law generally doesn't require cash compensation, although tarmac protections and refund rights can apply.

Flight delay checklist: what to do first

Before leaving the gate area, collect enough information to show what happened:

• [ ] Screenshot the original itinerary, boarding pass, airline app, gate screen, and each delay notification.
• [ ] Record the scheduled and revised departure and arrival times.
• [ ] Save the airline's stated reason, even if it later changes from weather to an operational problem or another explanation.
• [ ] Ask whether your connection is protected and whether all segments are on the same ticket or reservation.
• [ ] Ask what the airline will provide: meals, hotel, ground transport, rebooking, or a refund.
• [ ] Before paying for anything, request written instructions or confirmation where possible.
• [ ] Keep itemized receipts for reasonable expenses the airline doesn't cover.
• [ ] Photograph your boarding pass, baggage tag, and any written notice before the trip changes again.

The first explanation may be provisional. Keep the original message alongside any later update.

Which passenger-rights law applies?

The operating carrier and the airports on the itinerary matter more than the airline logo on the booking. Check the airline that is actually flying the disrupted segment, especially when the booking is a codeshare.

EU261 and UK261 are similar, but they're separate regimes. A trip can involve different rules on different legs. A connection on one reservation can also be treated differently from two flights bought on separate tickets.

The Your Europe air-passenger-rights guidance is a useful starting point for an EU-covered flight.

EU261 and UK261 delay rights

There are three separate questions under the EU and UK systems:

1. Is the airline required to provide care while you wait?
2. Is fixed compensation due after you arrive?
3. Do you want to continue the trip or take a refund after a long departure delay?

Care at the airport

For a covered flight, the airline generally must provide reasonable care after these departure-delay thresholds:

Care can include meals and refreshments, two communications, and hotel accommodation plus transport when an overnight stay is necessary.

The care threshold isn't the cash-compensation test. A two-hour departure delay on a short flight may require meals, while a delay that is later made up in the air may produce no compensation because the final arrival was less than three hours late.

Ask the airline to arrange care before spending your own money. When that isn't practical, choose a reasonable option and keep the itemized receipt. A luxury hotel, alcohol, or unrelated purchases may not be reimbursed.

Care can still be due when fixed compensation isn't. Bad weather, air-traffic restrictions, or another extraordinary circumstance may remove the compensation entitlement without removing the airline's obligation to provide meals or overnight accommodation.

Fixed compensation

EU261 or UK261 compensation generally requires each of these conditions:

1. The applicable regulation covers the flight.
2. You reach your final destination at least three hours later than scheduled.
3. The airline can't rely on an extraordinary circumstance for the delay.
4. No rerouting rule reduces the standard amount.

For a connecting itinerary on one reservation, the important delay is usually the time you reach the final destination, not merely the delay on the first segment. Compensation distance is generally measured from the first departure to the final destination, so don't assume that each flight is assessed separately. Separate tickets may not give you the same protection for a missed connection.

Rerouting can reduce compensation by 50% when you reach the final destination within the relevant window:

• Up to 2 hours late for the shortest distance band.
• Up to 3 hours late for the middle distance band.
• Up to 4 hours late for other flights over 3,500 km.

A four-hour long-haul delay therefore isn't automatically worth the full EUR 600 or GBP 520. The route, final arrival time, operating carrier, and reason for the disruption still matter.

Refund after a long departure delay

Once a covered EU or UK flight has a departure delay of at least five hours, you can generally choose not to travel and request a refund for the unused journey. When the trip no longer serves its purpose, the rules can also require a return flight to your original departure point where relevant.

Tell the airline plainly whether you want to continue or want a refund. Don't accept a travel credit by mistake if your request is for money back. A credit, a normal fare-rule cancellation, and a statutory refund can be treated as different things.

U.S. flight delay rights

For an ordinary U.S. gate delay, federal law generally doesn't require the airline to pay cash compensation, provide a meal, or book a hotel. The airline's contract of carriage and customer-service plan may offer more generous help.

Some carriers make commitments for controllable disruptions, including certain mechanical or crew-related delays. The DOT airline customer-service dashboard lists carrier commitments for meals, hotel rooms, rebooking, and other assistance in specified situations. Those commitments have their own conditions; they aren't one universal federal delay benefit.

U.S. tarmac delays

A tarmac delay is different from waiting in the terminal. When passengers are held on an aircraft at a U.S. airport, the airline generally must provide:

• Adequate food and drinking water no later than two hours after the tarmac delay begins, unless safety or security considerations prevent it.
• Operable toilets and medical attention when needed.
• An opportunity to deplane within three hours for a domestic flight or four hours for an international flight, subject to safety, security, and air-traffic-control exceptions.

These protections don't create a cash-compensation claim. They also don't apply simply because you have been waiting at the gate for several hours. The DOT Fly Rights guidance covers these protections and the complaint process.

U.S. refunds

When an airline cancels a flight or makes a significant change and you don't accept the alternative itinerary, DOT rules generally require a refund rather than forcing you to take a voucher. A long delay may count as a significant change, but not every delay does; the itinerary and the precise change matter.

Ask for a refund if you no longer want to travel. Accepting a substitute flight and completing the trip can affect whether you still qualify for a refund for the transportation. A refund is also different from compensation: a refund returns money for transportation you didn't accept, while compensation is an additional payment available under some non-U.S. regimes.

Rebooking, refunds, and overnight stays

Don't independently buy a replacement flight before asking what the airline can do unless time or safety leaves no practical alternative. In the U.S., self-booked replacement travel is often reimbursed only when the airline authorizes it or its policy allows it. Under EU261 or UK261, an airline's failure to provide required rerouting or care may support a reasonable expense claim, but the receipt and the record of what you asked for still matter.

How the delay reason affects a claim

The reason usually matters most when you're seeking EU or UK fixed compensation.

An airline shouldn't defeat an EU or UK claim with only a vague label such as "operational reasons." Ask which event caused the delay and why the airline considers it extraordinary. A routine mechanical problem isn't automatically extraordinary, although unusual technical events can require a case-by-case assessment.

Airline policies are separate from legal rights

An airline may offer more help than the law requires. The terms can vary by route, fare, operating carrier, and whether the disruption was within the airline's control. A company policy can fill a gap in federal law, but it doesn't automatically replace a statutory refund or EU or UK compensation right.

For example, Delta's published delayed-or-canceled-flight guidance describes possible options for a significant delay, missed connection, or cancellation caused by factors within Delta's control. The page uses discretionary wording, so treat it as Delta policy rather than a guarantee of federal compensation.

Check the airline app, website, kiosk, or help desk for rebooking options. Save the offer before accepting it. A goodwill voucher, eCredit, mileage award, or meal coupon isn't automatically a substitute for a refund or fixed compensation.

Evidence and the claim process

Keep the records that connect the disruption to your request:

• Booking confirmation, ticket number, and boarding passes.
• Flight number, operating carrier, route, and travel date.
• Scheduled and actual departure and arrival times.
• Screenshots of delay notices, gate boards, emails, and app messages.
• The airline's stated reason for the disruption.
• Receipts for meals, accommodation, transport, and communications.
• Proof that you asked for a voucher, hotel, rebooking, or refund, together with the airline's reply.
• A baggage report and baggage receipts if checked luggage was also delayed or lost.

Separate requests can make the result clearer:

1. Care expenses: List each expense, explain why it was necessary, and attach the receipt.
2. EU261 or UK261 compensation: State the final-arrival delay and the rule you believe applies.
3. Refund: State that you didn't accept the replacement itinerary and want the unused fare returned.
4. Goodwill request: Keep this separate from a legal compensation claim so the airline knows which payment you're seeking.

Start with the operating airline's official claim form or customer-relations channel. A short claim with exact times is easier to review:

Flight [number] on [date] arrived at [final destination] at [actual time], compared with the scheduled arrival of [time]. I request [expense reimbursement, EU261 or UK261 compensation, or a refund]. My booking confirmation, delay notices, and receipts are attached.

When an airline rejects an EU or UK claim, ask for the exact reason and the evidence supporting its extraordinary-circumstances defense. You can then consider the relevant national enforcement body or an approved alternative-dispute-resolution scheme where available. In the UK, check the airline's ADR route and the Civil Aviation Authority's consumer guidance.

For a U.S. complaint, use the DOT Fly Rights page. A DOT complaint is a regulatory complaint, not a guaranteed individual compensation award. Court deadlines and ticket-contract terms can differ, so don't rely on a generic claims website's deadline. EU261 has no single filing deadline across every EU country, and UK limitation periods differ by legal system. File promptly.

Other payments that are easy to confuse

• Refund: Money returned for an unused ticket when the applicable refund rule is met.
• Expense reimbursement: Reasonable costs for required care, such as meals or a hotel.
• Fixed compensation: An additional payment available mainly under EU261 or UK261 when the legal test is met.
• Voucher or credit: An airline offer that may have expiration dates or other restrictions.
• Travel insurance or card benefit: A separate contract with its own delay threshold, exclusions, and proof requirements.

For some international carriage, the Montreal Convention may provide a separate route for documented financial losses caused by a flight delay, subject to its conditions and liability limits. It isn't an automatic fixed payment for inconvenience.

A delayed checked bag is a separate baggage claim. Report it promptly and keep the baggage report and receipts for necessary purchases.

Frequently asked questions

Do weather delays qualify for compensation?

Usually not for fixed EU261 or UK261 compensation when the weather is an extraordinary circumstance. Care, such as meals or a hotel when required, can still be due in the EU or UK. In the U.S., there's generally no federal cash payment for a weather delay.

Does a two-hour flight delay qualify?

In the EU or UK, two hours may trigger care for a flight in the shortest distance band, but it doesn't by itself trigger fixed compensation. Compensation generally depends on arriving at least three hours late at the final destination. In the U.S., a two-hour terminal delay usually creates no federal meal or cash entitlement, while a two-hour tarmac delay triggers the aircraft food-and-water rule.

What if I miss a connecting flight?

Tell the airline immediately and confirm whether every segment is on one reservation. For EU or UK-covered travel, the final arrival delay on a single booking may support compensation. With separate tickets, the second airline can usually apply its own missed-flight terms.

Can I claim a hotel I booked myself?

For EU or UK-covered travel, a reasonable hotel and necessary transport may be reimbursable when the airline failed to provide required care. In the U.S., reimbursement usually depends on the airline's policy, authorization, travel insurance, or a card benefit. Ask first and keep the written response.

Is a four-hour delay worth EUR 600 or GBP 520?

Not automatically. The flight must fall under EU261 or UK261, the final-arrival delay must meet the compensation test, and no extraordinary circumstance can apply. Rerouting can reduce the standard amount. A U.S. flight doesn't receive that fixed payment under federal delay rules.

Before leaving the airport, save the final delay notice, ask for a written decision about care or rebooking, and keep every receipt. Those records give the airline or regulator something concrete to assess.
