Start with the airline that operated your flight. That's the first stop for a U.S. airline service complaint. If the carrier doesn't fix the problem, the Federal Aviation Administration directs consumers to the U.S. Department of Transportation's Aviation Consumer Protection website.
The remedy depends on what happened. A canceled flight, a long delay, a mishandled bag, and a poor customer-service experience follow different rules and company policies. Don't assume every disruption qualifies for cash.
Who should receive your complaint?
Check your confirmation for "operated by." The operating carrier is usually the best first contact for a delay, cancellation, onboard issue, or baggage problem. Bought the ticket through an online travel agency or another seller? Contact that company too when the dispute involves payment, ticketing, or a refund.
For a codeshare, send the complaint to both companies if you're unsure which one controls the issue. Include the flight number, date, and operating carrier so the complaint can be routed correctly.
| Problem | First contact | What to request |
|---|---|---|
| Cancellation or major schedule change | Operating airline and, if needed, the ticket seller | Rebooking or a review of your refund options |
| Flight delay | Operating airline's airport desk or customer relations team | Rebooking, an explanation, and any assistance available under the airline's policy |
| Lost, delayed, or damaged baggage | Airline baggage service office | A baggage report, tracking number, delivery, and review of eligible expenses or fees |
| Ticket, payment, or booking error | Ticket seller and airline | Written correction, refund review, or an explanation of who controls the transaction |
| Unresolved service complaint | Airline customer relations department | A written response and the specific resolution you want |
Airports generally don't control an airline's schedule, ticket terms, or baggage-claim decision. For ordinary service complaints, don't start there.
Refund, reimbursement, and compensation are different
Use the right term in your request:
- Refund: Money returned for a ticket or service you didn't use. If the airline cancels your flight or makes a significant schedule change, ask whether you can decline the alternative and receive a refund to the original payment method. Accepting a replacement flight or travel credit can affect the options still available, so state your preference before you accept.
- Reimbursement: Repayment for an eligible expense, such as a necessary purchase tied to a baggage problem or a disruption covered by the airline's policy. Keep receipts and ask for the policy in writing.
- Compensation: An extra payment for inconvenience or delay. A late arrival doesn't automatically mean cash is owed. The United States has no single payment formula for every ordinary flight delay, so check the airline's conditions of carriage and any rules that cover your itinerary.
A voucher isn't the same as a cash refund. Before you take one, check the expiration date, route restrictions, transfer rules, and whether accepting it closes another request.
What to do at the airport
Act before you leave whenever you can.
Save the evidence first: the original itinerary, delay or cancellation notices, rebooking offers, boarding passes, and baggage-tag details. Screenshot them.
Ask what caused the disruption, and request the reason in writing if possible. Weather, air-traffic restrictions, staffing, aircraft problems, and other causes may be treated differently under the airline's assistance policy.
Tell the agent the outcome you want: travel on the next available option, or a refund review instead of the proposed replacement. If you keep traveling, ask whether meals, a hotel, ground transportation, or other help is offered for this type of disruption. Get the answer and any voucher terms in writing.
Don't assume an expense will be repaid. Ask whether it's eligible before you spend, and keep an itemized receipt if you have to pay out of pocket. A phone conversation is easier to follow up when you have the agent's name, the date, and a case number.
If the airline cancels your flight and the proposed replacement no longer works, don't accept a credit and hope it can later become a refund. Say you are declining the substitute and ask for the applicable refund process.
How to report delayed or missing baggage
Go to the airline's baggage service office, usually near baggage claim, before you leave the airport. Ask the representative to create a mishandled baggage report, often called a Property Irregularity Report, and give you the reference number.
Photograph your baggage tag and keep that report number. Describe the bag accurately, including brand, color, size, and distinguishing marks. Provide a delivery address and a reliable phone number. Save receipts for necessary purchases and ask which expenses the airline's policy covers. Report damage immediately and follow the carrier's written claim instructions.
If there's no baggage desk, use the airline's online reporting form and save the confirmation. Deadlines can be short and can differ for damage, delay, and international travel. Don't wait for the bag to turn up before making the initial report.
Travel insurance or a homeowners policy may cover some losses on a separate track. That coverage doesn't replace the airline's baggage process.
How to write an effective airline complaint
Send it through the airline's official website, app, email channel, or customer-relations address. A clear chronological account is more useful than a long description of the frustration.
Include:
- Your name and contact information
- Confirmation code and ticket number, if available
- Flight number, date, route, and operating carrier
- The original and actual departure and arrival times
- A short timeline of what happened
- Names or descriptions of staff you spoke with
- Your requested resolution
- Receipts, screenshots, notices, and baggage-report information
Don't put your full credit-card number, account password, or extra identity documents in an ordinary email.
You can use this format:
Subject: Complaint about flight [number] on [date] - confirmation [code]
I was booked on [route]. The flight was [delayed, canceled, or affected by a baggage problem] at [time]. I contacted [airline or agent] on [date] and received [response].
I am requesting [refund review, reimbursement of a listed expense, baggage delivery, or another specific remedy]. Attached are [documents]. Please confirm the applicable policy and provide a written response.
Give the airline a reasonable chance to respond, then follow up in the same thread. If it denies the request, ask for the reason and the specific contract or policy provision it relied on.
Escalating an unresolved complaint
If the airline does not resolve a service complaint, submit it to the Department of Transportation's Aviation Consumer Protection system. FAA guidance says to use the DOT aviation consumer protection website for airline service complaints: FAA complaint guidance.
Attach your airline correspondence and identify the result you want. A DOT complaint can document a possible consumer-protection problem and help regulators monitor airline practices. It isn't a guaranteed refund or compensation process.
If a travel agency sold the ticket, copy the agency on the escalation. A credit-card billing dispute is a separate process with its own requirements. Preserve your airline requests and check the card issuer's rules before treating a card dispute as a substitute for an airline or DOT complaint.
Limits and jurisdiction exceptions
These complaint routes are for U.S. consumers and U.S. filings. A flight departing from another country may be subject to that country's passenger-protection rules, even if the airline is American. UK and European rules can use different tests for cancellation notice, replacement-flight timing, and compensation.
Don't mix a U.S. DOT complaint with assumptions about UK or European compensation. Check the regulator for the country connected to the itinerary, and identify the departure airport, operating carrier, and arrival delay.
Accessibility, discrimination, safety, and security concerns should be labeled clearly. Include the exact conduct, date, location, and people involved instead of describing the problem only as a general service failure.

Frequently asked questions
Who do I contact first about an airline service complaint?
Contact the airline that operated the flight. If you bought the ticket through a travel agency, notify the seller as well. For a codeshare, copy both carriers if responsibility is unclear.
Does every delayed flight qualify for compensation?
No. Don't assume a payment from a delay alone. Ask about rebooking and assistance under the airline's policy, then check whether a specific rule covers your route or situation.
Should I accept a voucher after a cancellation?
Only if it fits your needs. A voucher may expire, carry restrictions, and close off a refund. If you prefer a refund, say so before you accept a replacement or credit.
Is the FAA the right place to file an airline service complaint?
The FAA's service-complaint guidance directs consumers to the Department of Transportation's Aviation Consumer Protection website. Start with the airline, keep its response, and use the DOT route if the issue remains unresolved.
Pull up your confirmation, note the operating carrier, and send a written request that states the outcome you want. Keep that thread, then use DOT Aviation Consumer Protection only after the airline has had a chance to respond.
