Yes, you can sue an airline for not refunding your money, and small claims court is where most passengers win that fight. Federal rules that took effect in 2024 require airlines to issue automatic cash refunds when they cancel a flight or make a significant schedule change, and those rules apply even to non-refundable tickets. A lawsuit is usually the last step. Before you file, confirm the airline actually owes you the money, then push through a Department of Transportation complaint and, if you paid by card, a chargeback. Court is what you use when those fail.
Confirm the Airline Owes You a Refund
A federal regulation now spells out when an airline must return your money. If the airline cancels your flight for any reason and you decline rebooking or a voucher, the refund is automatic. You do not have to ask. The DOT has declared it an unfair business practice to withhold a refund in that situation, and the rule reaches non-refundable tickets.1Federal Register. Refunds and Other Consumer Protections
A “significant schedule change” also triggers a refund if you decline the new itinerary. The regulation defines that as:2eCFR. 14 CFR Part 260 – Refunds for Airline Fare and Ancillary Service Fees
- A departure or arrival that shifts by three or more hours domestically, or six or more hours internationally.
- A change to a different departure or arrival airport.
- An itinerary with more connections than you originally booked.
- A downgrade to a lower class of service.
Refunds also apply to services you paid for but didn’t get. A checked bag that arrives more than 12 hours after your domestic flight reaches the gate entitles you to a refund of the bag fee. Paid extras like seat upgrades or Wi-Fi the airline never delivered work the same way.3U.S. Department of Transportation. What Airline Passengers Need to Know About DOT’s Automatic Refund Rule
If none of these apply — you changed your mind, you missed the flight, the weather was fine and the plane left on time — federal law does not force the airline to refund you, and your only argument is whatever the airline’s own contract of carriage promises.
Cash, Not Vouchers, and the Deadlines That Matter
When a refund is owed, the airline must return the money in the original form of payment. Credit card charges go back on the card. Cash purchases get cash. A travel credit is not a default substitute. The airline can offer a voucher, but only alongside a clear statement of your right to cash, and you have to affirmatively accept it. Silence does not count as agreement. A voucher you do accept must be good for at least five years.2eCFR. 14 CFR Part 260 – Refunds for Airline Fare and Ancillary Service Fees
The refund must be processed within seven business days for credit card purchases and 20 calendar days for other payment methods.3U.S. Department of Transportation. What Airline Passengers Need to Know About DOT’s Automatic Refund Rule Once those deadlines pass, the airline is out of compliance with federal rules, and that fact becomes part of your case.
File a DOT Complaint First
Before suing, complain to the DOT. It costs nothing, it puts the airline on notice from its federal regulator, and it creates the paper trail a small claims judge will want to see.
The complaint goes through the DOT’s online consumer protection portal. Have your booking confirmation, flight numbers and dates, and any correspondence with the airline ready. Describe the problem specifically: what happened, why federal rules require a refund, and what the airline said when you asked.4U.S. Department of Transportation. OACP Form – Aviation Consumer Protection
The DOT forwards your complaint to the airline, which must acknowledge it within 30 days and provide a written response within 60 days.5eCFR. 14 CFR 259.7 – Response to Consumer Problems A lot of disputes end here, because most airlines would rather pay than explain themselves.
Dispute the Charge With Your Card Issuer
If you paid by credit card, a chargeback is often faster than court. A flight that was canceled without a refund is a textbook “services not rendered” dispute.
The deadline is strict. You must send a written dispute to your card issuer within 60 days of the statement date showing the charge.6Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors That clock runs from the statement with the original charge, not from the travel date. If you booked six months ahead and the cancellation just happened, you may already be past this window. Some issuers give more time than the law requires, but do not assume it.
The issuer must acknowledge the dispute within 30 days and resolve it within two billing cycles, and generally applies a provisional credit while it investigates.6Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors Attach your DOT complaint and the airline’s response. One thing to watch: if the airline offered you a voucher and you never explicitly rejected it, some issuers will treat that as a remedy already provided.
Sue for Breach of Contract, Not Consumer Fraud
This is where passengers get tripped up. You cannot sue an airline under most state consumer protection laws. The Airline Deregulation Act bars states from enforcing laws “related to a price, route, or service of an air carrier,”7Office of the Law Revision Counsel. 49 USC 41713 – Preemption of Authority Over Prices, Routes, and Service and courts read that language broadly enough to knock out most state-law theories.
The Supreme Court left one important door open. In American Airlines, Inc. v. Wolens, the Court held that passengers can sue airlines for failing to honor their “self-imposed undertakings” — meaning the promises the airline made in its own contract of carriage.8Justia. American Airlines, Inc. v. Wolens Your suit has to live inside that contract and the federal regulations that fill it out. You cannot ask a court to impose obligations on the airline based on state ideas of fairness.
Every airline posts its contract of carriage online. Read the sections on cancellations, refunds, and schedule changes before you draft anything. The federal automatic-refund rule sets a floor the contract cannot go below, but the contract may promise more, and the more the airline promised, the more you can ask for.
File in Small Claims Court
Small claims court is built for this: a specific dollar amount, no lawyer required, simplified procedure.
Pull Your Documentation Together
Collect the ticket confirmation, credit card statements, screenshots of the cancellation or schedule change notice, every email or chat transcript with the airline, and your DOT complaint with the airline’s reply. Write out any phone calls: date, time, agent name or ID, and what was said. Save the relevant sections of the contract of carriage.
Find the airline’s official legal name, which may differ from its brand name and is usually on the contract of carriage or your ticket. Then look up its registered agent for service of process on your state’s Secretary of State website. That’s the entity the court papers get delivered to.
File, Then Serve
File in the county where you live or where the airline does business, and make sure your claim is within the court’s dollar limit. Caps range from $2,500 to $25,000 by state, with most between $5,000 and $10,000. Filing fees run from about $15 to a few hundred dollars.
Get the complaint form (some courts call it a “statement of claim”) from the clerk or the court’s website. Name the defendant, state the amount, and explain the claim in plain terms: the flight was canceled, federal regulation requires a refund, the airline refused, and the documentation is attached.
Then serve the airline’s registered agent. Most courts allow certified mail; some require a process server or the sheriff’s office for a small fee. Once service is complete, the airline has a set window to answer, and the court schedules a hearing.9U.S. Department of Transportation. Air Travelers – Tell It to the Judge
What You Can Actually Recover
The refund is the core of the claim, but it isn’t necessarily the ceiling. Small claims judges award money damages, and that can include out-of-pocket costs the airline’s refusal forced on you. A hotel room you paid for after being stranded overnight, meals, ground transportation you had to arrange, and the price difference on a last-minute replacement flight are all recoverable if the airline should have covered them and didn’t.9U.S. Department of Transportation. Air Travelers – Tell It to the Judge
Keep the receipts. Judges want documented costs, not estimates. Do not pad the claim with speculative losses; a shaky number attached to a real one weakens both. The strongest cases are simple: here is what the airline owed under its contract and federal rules, here is what it refused to pay, and here is exactly what that refusal cost you.
