Flight Delayed or Canceled: What the Airline Owes You

Updated September 2026 · Vacation Checklists

Flight delayed or canceled by the airline? In the United States you have exactly one guaranteed right, and it is a refund, not a payout. If the airline cancels your flight or changes it significantly and you decide not to travel on what it offers instead, it owes you your money back in the way you paid. That is federal law. Almost everything else you may have heard about, the meal voucher, the hotel room, the goodwill miles, comes from the airline's own published promises, and promises can be rewritten.

Knowing which is which before you reach the desk is the difference between asking for something you are owed and asking for a favor. Both are worth asking for. They just work differently.

Updated September 2026. US passenger rules are in an unusually active period, with a refund rule in force since late 2024, an enforcement pause on one narrow piece of it, an open rulemaking on the definition of a canceled flight, and a separate reporting rule taking effect in October 2026 that reshapes which disruptions count as the airline's fault. Confirm the current position at the Department of Transportation's aviation consumer protection site before you rely on anything here. Nothing on this page guarantees a specific outcome.

A note on numbers. No dollar figures on this page. Fares, refund values and the ceilings written into federal rules are adjusted over time and differ by route, fare and carrier, so any amount printed here would be wrong for somebody. What you get instead is the rule, the trigger, the deadline and the document that decides your claim.

The Short Version, in One Table

Read that table twice. The two columns that matter are not "delay" and "cancellation." They are required and promised. Required survives a bad mood at the gate. Promised does not always survive a policy update.

Flight Delayed or Canceled: The Refund Rule in One Page

The current federal refund rule took effect on October 28, 2024 and it changed the mechanics more than the principle. Airlines already owed refunds. What changed is that the refund is now supposed to arrive without you chasing it.

The core of it:

• It applies to scheduled flights to, from, or within the United States, including foreign carriers on those routes, and it covers nonrefundable tickets. A nonrefundable ticket is refundable when the airline is the one that broke the itinerary.
• The refund is automatic when the airline cancels and offers you nothing you accept, or when you reject a significantly changed flight and the rebooking offered, or when you reject a voucher offered instead.
• It is the full fare, including taxes and the ancillary fees you paid on top.
• It goes back in the original form of payment. Card purchases return to the card. Miles return as miles. The airline cannot substitute a voucher and call it done.
• The clock is defined. Card refunds are due within seven business days. Refunds for cash, check, debit and other methods are due within twenty calendar days.
• No processing fee may be deducted from a refund that is owed.
• A voucher only counts if you actually said yes to it. A carrier is not allowed to treat silence, a clicked rebooking, or a default option as acceptance.
• If you do accept a voucher instead, it has to stay valid for at least five years from issue, and the airline has to tell you the expiration date and disclose blackout dates, advance purchase rules and other restrictions at the time it makes the offer.

One practical wrinkle that trips people up: the refund obligation follows the merchant of record, meaning whoever actually charged your card. Book direct and the airline refunds you. Book through an online travel agency and the agency is often the one that has to send the money back, with the airline required to tell it promptly that you qualify. If an agency stalls, say the words "merchant of record" and ask which party is holding the funds.

What Counts as a "Significant" Change

This is the part worth memorizing, because airlines will happily move you two hours and fifty minutes and call it a schedule adjustment. The federal definition is specific.

There is also a separate set of triggers for a passenger with a disability: a downgrade that removes a needed accessibility feature, a rerouting through different connecting airports, or a substitute aircraft that lacks an accessibility feature the original had.

Two things follow from that table. First, an airport swap has no time threshold at all. If they move you from the close airport to the far one, that is a significant change however convenient the new time looks. Second, an added connection is a trigger on its own. A nonstop turned into a one stop is a significant change even if you land at the same minute.

If any trigger is met, you have a choice, not an obligation. Take the new flight, take a voucher, or take the refund. Only the refund is guaranteed to be there in the form you paid.

The Renumbered Flight Gap, and Why It Matters Right Now

Under the rule as written, a flight that operates under a different flight number than the one you bought is a canceled flight, which would trigger refund rights even if the aircraft leaves at the same time from the same gate.

Airlines pushed back, arguing that renumbering is routine and usually invisible to passengers. The Department of Transportation responded by pausing enforcement rather than changing the text. The pause first ran from December 5, 2025 through June 30, 2026, and was then extended by a notice published July 7, 2026, running to July 7, 2027. It applies only where the passenger is rebooked onto the renumbered flight and that flight operates without a significant change or delay as defined above.

At the same time the Department opened a rulemaking, informally "Refund III," to consider redefining a canceled flight outright.

What this means for you, as of September 2026:

• If your flight number changed but nothing else did, do not expect a refund, and do not build a claim on it.
• If the flight number changed and the timing, airport, connections or cabin also moved past a trigger, the ordinary rule still applies and the pause does not protect the airline.
• The definition itself may change. Check the current status before citing it, because an enforcement pause is a policy choice that can be revisited.

The Hard Truth About Plain Delays

There is no US equivalent of a compensation check for a late flight. A domestic flight can leave five hours late for a reason entirely of the airline's making, deliver you tired and furious, and owe you nothing in cash. What it owes you is transportation, and if the delay crosses the significant threshold and you walk away instead, a refund.

Two honest caveats.

Airlines often pay anyway. Goodwill miles, a travel credit, or a partial refund are common outcomes of a polite written complaint, especially for a controllable failure. That is a business decision, not an entitlement, and it varies by carrier, route and how the complaint reads.

Rules elsewhere are genuinely different. Some jurisdictions do require cash for delay. If any part of your trip touched Europe or the UK, the framework there is a separate system with its own thresholds and exclusions, and our missed flight guide walks through how that regime treats a disrupted journey. Do not assume it applies to a purely domestic US ticket. It does not.

Meals and Hotels: Promises, Not Statutes

Whether you eat and where you sleep is decided by a phrase you will hear over and over at the gate: controllable or uncontrollable.

Controllable means the airline created the problem. Maintenance, crew scheduling, an IT failure of its own making. Uncontrollable means something outside it: weather, air traffic control, a security event. US carriers publish customer service plans that commit to meals for long controllable delays, and most commit to a hotel and ground transport for a controllable overnight. The Department of Transportation maintains an airline customer service dashboard that shows, carrier by carrier, which commitments each one has actually made. That dashboard is the thing to check, not a general article, because the commitments are not identical and they are not law.

A change worth knowing about. A final rule published September 3, 2026 and effective October 19, 2026 implements a section of the 2024 FAA reauthorization by creating a new reporting category for ten kinds of events that are formally excluded from the "air carrier" cause code. The excluded events include things like unscheduled maintenance that shows up outside a scheduled maintenance program and cannot be deferred before flight, cybersecurity attacks where the carrier was in compliance with applicable cybersecurity regulations, government system failures, medical emergencies not caused by the airline, removal of an unruly passenger, and airport closures from volcanic ash or wind.

Because most carrier commitments are written against the word "controllable," moving events out of that bucket can move them out of the promise. The Department itself acknowledged that the total value of amenities provided to passengers could decline. Practical effect from late October 2026 onward: ask, do not assume, and read the carrier's own customer service plan rather than a summary of what airlines used to do.

Three habits that help on the night itself:

• Ask at the desk before you leave the terminal. Chasing a voucher afterward is much harder than getting one in person.
• Ask the precise question: are you providing the room, or reimbursing me for one? Those are different answers and the second one needs receipts.
• Keep everything. Receipts, the boarding pass, a photo of the departure board showing the status. Paper is what an insurer or a card benefit administrator pays against.

Bag Fees and Paid Extras You Can Get Back

Separate from the fare, the federal rule also covers money you paid for things you did not receive.

Checked bag fees. A bag fee must be refunded when the bag is lost, or significantly delayed. Significantly delayed is defined by clock: 12 hours after arrival for a domestic itinerary, 15 hours for an international itinerary whose nonstop segment between the US and a foreign point is 12 hours or less, and 30 hours where that segment is longer than 12 hours. The refund is not automatic on its own. You have to file a mishandled baggage report with the operating carrier, or with the carrier that flew the last segment on a multi carrier itinerary. No report, no bag fee refund. Our guide on lost luggage: what to do covers the report itself and the claim that sits on top of it.

There are carve outs. The refund is not owed if the delay happened because you did not pick up and recheck the bag at the first international entry point into the US, if you did not collect a bag that arrived on time, or if you agreed to travel without the bag on that flight. That last one has a guardrail: an airline can ask a late arriving or standby passenger to agree to a new delivery time for a bag, but it cannot require you to waive your right to a bag fee refund if the bag is lost, your right to compensation if the bag is damaged or pilfered, or your right to reimbursement of incidental expenses if the bag misses even the new agreed delivery time.

Everything else you bought. Seat selection, extra legroom, priority boarding, an inflight meal, paid wifi. If the service was not provided through no fault of your own, the fee is refundable. This is the quietest money on the whole ticket and almost nobody claims it. Itemize it in the complaint.

Rebooking on Another Airline

No US rule requires an airline to buy you a seat on a competitor. What exists instead is interline agreements, commercial arrangements that let one carrier endorse your ticket over to another, plus a lot of agent discretion.

How to improve your odds without annoying anyone:

• Use the word "protection." Asking to be "protected on another carrier" is the industry phrase and it lands better than a general complaint.
• Bring a specific flight. Agents move faster when you hand them a flight number on a partner airline than when you hand them a problem.
• Know the limits. Ultra low cost carriers typically have few or no interline agreements, which means when they cancel, the next seat is their own next seat. That may be days out in peak season.
• Do not buy your own replacement ticket first. Buying a separate ticket usually ends your claim against the original carrier and can void the unused portion of your itinerary. Ask the agent to note the file before you spend anything.

Worked Example: Reading Your Own Situation

Your nonstop is canceled at 6:00 pm. The airline offers you a flight the next morning that connects through a second city and lands seven hours later than your original arrival.

Work it in order:

1. Is there a trigger? Yes, twice over. The arrival moves more than three hours on a domestic itinerary, and the itinerary gains a connection. Either one alone would be enough.
2. What are the options? Fly the new itinerary, accept a voucher if one is offered, or take the refund. You pick.
3. What is the cause? If the agent says maintenance or crew, that is controllable, so ask for the meal voucher and the hotel and check what your carrier's plan commits to. If the agent says weather, expect a rebooking and the offer of a discounted distressed passenger rate instead.
4. What did you pay for that you will not get? The seat you selected on the canceled flight, the wifi pass, the checked bag if you now go home instead. Itemize it.
5. What do you document? The cancellation notice with its timestamp, the stated cause in writing, the alternative offered, and the moment you declined it.

Step five is the one people skip and later need. Take screenshots of the app at every stage, because the airline's own messages are the cleanest evidence you will ever have.

If the Airline Says No

Escalate in this order, and do it in writing.

1. The airline's own consumer office. Federal rules require carriers to acknowledge a written complaint within 30 days and to send a substantive response within 60. State what happened, state which rule or which published commitment you are relying on, and attach the documents. Ask for a specific remedy.

2. The Department of Transportation. Complaints go through the Office of Aviation Consumer Protection's complaint form. A filed complaint does not act as a court and will not force a settlement in your case, but the office enforces these rules against carriers and a pattern of complaints is how enforcement starts.

3. Your card issuer, carefully. A chargeback is a real option for a refund the airline owes and has refused. Do not start one while an airline claim is still open, because dueling processes tend to freeze both.

4. Your insurance or card benefits. This is where the money for the hotel, the meals and the missed hotel night actually lives, because none of it is required of the airline. Our guide to travel insurance explained covers which coverages pay out, which ones you already have through a card, and the filing deadlines that quietly kill claims.

Reduce the Odds Before You Fly

• Take an earlier flight than you need. A morning departure gives the day room to recover. An evening departure is the last chance of the day.
• Do not schedule the unmissable thing for arrival day. A cruise departure, a wedding, a connection to a tour. Arrive the day before.
• Turn on airline alerts and check in at 24 hours. You want to learn about a change while seats on the alternative still exist.
• Fly with your essentials on you. A change of clothes, chargers, medication and documents in the carry on.
• Plan around the worst weeks. Peak holiday periods compress everything, and our holiday travel checklist covers the timing decisions that keep a busy travel week from collapsing.

Frequently Asked Questions

Does the airline have to pay me if my flight is delayed?

In the United States, no. There is no federal cash compensation for delay. If the delay crosses the significant change threshold, three hours domestic or six hours international, and you choose not to fly, you are entitled to a refund of what you paid. Any payment beyond that is the airline's own goodwill and varies by carrier.

My flight was canceled and they rebooked me. Can I still get a refund?

Yes, if you decline the rebooking. The refund right applies when the airline cancels or significantly changes the flight and you choose not to travel on the alternative. Accepting the new flight ends the refund claim, and accepting a voucher ends it too, which is why the rule requires you to affirmatively agree to a voucher rather than have one assigned to you.

How long does an airline have to refund me?

Refunds to a credit card are due within seven business days. Refunds for cash, check, debit and other payment methods are due within twenty calendar days. The refund must go back in the original form of payment, and the airline is not permitted to keep a processing fee out of it.

Will they pay for my hotel if I am stuck overnight?

Only if they promised to. Hotels and meals are commitments in an airline's customer service plan, not obligations in law, and they generally apply to delays within the airline's control. Check your carrier's entry on the Department of Transportation's customer service dashboard, and be aware that a rule effective October 19, 2026 moves several categories of disruption out of the "air carrier" cause code, which can narrow those commitments.

Can I get my checked bag fee back if my bag was late?

Yes, once the delay passes the defined threshold, which is 12 hours for a domestic itinerary and 15 or 30 hours for international itineraries depending on the length of the nonstop segment. The catch is that you must have filed a mishandled baggage report with the operating carrier. Without that report, the refund obligation does not start.

My flight number changed but the flight still operated. Is that a cancellation?

Under the text of the rule, yes. In practice, the Department of Transportation has paused enforcement for renumbered flights where the passenger is rebooked and the flight operates without any significant change or delay, with the current pause running to July 7, 2027 while a rulemaking considers redefining the term. Treat a pure renumbering as not producing a refund, and check the current position before claiming.

Does the airline have to put me on a different airline?

No US rule requires it. Many carriers do it anyway under interline agreements, and asking to be protected on another carrier with a specific flight in mind is the way to make it easy for the agent to say yes. Ultra low cost carriers often have no interline agreements at all, so their next available seat is genuinely their own.

What should I do first when a flight cancels?

Get in the physical line and open the app at the same time, and take screenshots as you go. Decide early whether you want to travel at all, because that single decision determines whether you are asking for a rebooking or claiming a refund. If you are trying to recover a broken connection rather than a canceled outbound, our guide to what to do after a missed flight covers the recovery sequence in detail.
