For U.S. travelers, the question that matters after a flight problem is usually what you can request next. If an airline cancels or significantly modifies a covered flight, you may generally accept an alternative or ask for a refund if you don't take that alternative. Canceling on your own, waiting out a delay, reporting baggage trouble, and filing a service complaint each follow a different path.
Save the booking record first and identify who caused the disruption. That classification often decides whether you're asking for a refund, a rebooking, extra-cost reimbursement, or a complaint.
Quick answer: what to do after an airline problem
- Airline cancellation or significant change: Check whether the U.S. Department of Transportation refund rules apply. If you decline the alternatives offered, ask for the refund option in writing.
- You cancel voluntarily: Read the fare conditions and the airline or ticket agent's policy. Don't assume the airline-cancellation refund rule applies.
- Flight delay: Ask about rebooking and check the carrier's terms. There isn't one U.S.-wide cash payment for every delay.
- Delayed or damaged baggage: Report it promptly, get a file reference number, track the bag, and keep receipts and photos.
- Airline service complaint: Keep the airline's case number and written response, then use the DOT Aviation Consumer Protection complaint route if you still need a federal complaint.
What rule or policy controls your situation?
| Situation | What usually needs to be checked first | Your next step |
|---|---|---|
| The airline canceled or significantly modified the flight | The applicable DOT refund rule and the disruption recorded on your booking | Decide whether to travel on the offered alternative or request a refund |
| You decided not to travel | Your fare conditions and the ticket seller's cancellation policy | Check refund, credit, expiration, and fee terms before canceling |
| Your bag is delayed or damaged | The airline's baggage-reporting process and itinerary-specific rules | File a report, save the reference number, and submit supporting documents |
| You want to complain about service | The airline's customer-care record and the DOT complaint route | Send a factual complaint with dates, documents, and the remedy requested |
| You booked through an agency or travel site | The airline's terms and the ticket agent's procedures | Contact both parties and identify who must process the request |
A refund and reimbursement aren't the same thing. A refund concerns the ticket. Reimbursement concerns extra expenses, such as replacement items, and it depends on separate rules, policies, or coverage.
If the airline cancels or significantly changes your flight
The Federal Register notice on airline refunds and consumer protections describes the DOT framework for cancellations and significant modifications. For a covered itinerary, the basic decision is whether you accept an alternative the airline offers.
If you still need to travel
Save the cancellation or schedule-change notice, including the original and replacement flight details. Check the airline's app and website for rebooking options before you wait in a long gate line.
If you bought the ticket through a travel agency or online booking platform, contact that seller too. It may have access to different rebooking systems or waivers, as noted in these flight-cancellation booking tips. Ask for written confirmation of the new itinerary, any fare difference, and any restrictions. Keep the original ticket receipt and every message about the change.
If the alternative doesn't work, say clearly that you decline it and want the refund that applies to the airline-initiated cancellation or significant modification. Don't assume a voucher or travel credit is your only option, and don't accept one before you check its expiration date and conditions.
A small schedule tweak and a significant modification may not be treated the same way. Ask the airline how it classified the change and review the applicable DOT rule instead of relying on a number you saw online.
If you no longer want to travel
Confirm that the airline, not you, initiated the disruption before you hit a voluntary-cancellation button. The same booking can show different options depending on whether it's recorded as an airline cancellation, a significant change, or a customer-initiated cancellation.
Use a written request such as:
I am declining the alternative offered for flight [number] on [date] and request the refund available for this airline-initiated cancellation or significant modification. Please confirm receipt and provide a case number.
Save the request, the response, and the date you sent it. If the airline says the ticket is only eligible for credit, ask it to identify the fare rule or disruption classification behind that decision.
A specific accessibility-related example
The Federal Register material states that, when an airline knows a passenger's personal wheelchair or scooter won't fit on the scheduled flight, DOT requires the airline to offer free rebooking on the next available flight of the same carrier or a partner carrier. That protection is discussed under 14 CFR 382.125(f)(2). Keep the airline's notice and ask for the accessibility-related rebooking option to be recorded in your case.
If you cancel the ticket yourself
A voluntary cancellation is a separate issue from an airline cancellation. There isn't one industrywide result for every fare, so check these items before you give up the booking:
- Whether the fare is refundable, nonrefundable, or subject to a credit policy
- The cancellation deadline and any stated fee
- The expiration date and restrictions on a travel credit
- Whether the ticket was sold directly by the airline or by an agent
- Whether travel insurance or a separate card benefit could apply
The airline's fare terms and the ticket seller's policy may control a voluntary cancellation. Don't describe a decision not to travel as an airline cancellation unless the airline actually canceled or significantly changed the flight.
If you already canceled by mistake, contact the airline or ticket agent promptly, explain what happened, and ask for the applicable policy in writing. A support representative may mention options, but don't treat an informal promise as confirmation until it appears in the booking record or written correspondence.
What to do when a flight is delayed
A delay raises a different question from a cancellation. There isn't a single U.S.-wide cash-compensation amount that applies to every delayed flight, so treat automatic-payment claims with caution.
At the airport, check the airline app and departure screens for the current status. Ask whether the airline can rebook you and whether the new itinerary changes your destination, connection, or fare conditions. If a third party issued the ticket, contact it as well as the airline. Save notices, chat messages, and the names or employee numbers of representatives when you can get them. Keep receipts for necessary expenses, but a receipt doesn't guarantee reimbursement.
If the delay later becomes a cancellation or a significant modification, ask the airline to explain what refund or rebooking options now apply. Get that answer in writing rather than relying on a verbal statement at the gate.
How to handle delayed or damaged baggage
Report a missing or damaged bag at the airline's baggage service desk as soon as possible, preferably before you leave the airport. Ask for a written report and the file reference number. Many airlines provide online tracking, and baggage claim guidance explains why that reference number matters.
Keep:
- Your baggage report and file reference number
- The baggage tag and boarding pass
- Photos of damage and the bag's condition
- Receipts for necessary replacement purchases
- Delivery updates and every message from the airline
- A copy of the claim you submit
Follow the airline's stated reporting and claim deadlines. Those can differ depending on whether the bag is delayed, damaged, or considered lost. International itineraries may also involve different treaty-based baggage rules, so don't assume a domestic claim procedure covers every trip.
Receipts and photographs support a claim; they don't guarantee that every expense will be paid. Ask the airline which expenses it considers eligible and keep its response.
How to file an airline service complaint
Use the airline's official customer-service channel first when you need a booking correction, refund explanation, baggage update, or other direct response. Write a short timeline instead of a general complaint.
Include the passenger name and confirmation number; the ticket number, flight number, route, and travel date; what the airline changed or failed to provide; the date and method of each contact; case numbers and copies of replies; receipts or baggage documents; and the specific remedy you want.
For a federal airline service complaint, the FAA's complaint guidance directs consumers to the Department of Transportation's Aviation Consumer Protection website. Use that official route rather than an unverified claims service.
A DOT complaint is separate from an airport rebooking request. If you still need to travel, handle the immediate booking problem with the airline or ticket agent while you preserve the documents for the complaint.
If the airline refuses your request
Ask the airline for the reason for the denial, the fare rule or policy it applied, whether the booking is recorded as an airline-initiated or voluntary cancellation, and the case number plus the next escalation option.
Send the same documentation to the ticket agent if an agency issued the ticket. Keep the request focused on one outcome, such as a refund, a corrected baggage claim, or a written explanation, so the response is easier to evaluate.
If the airline or agent doesn't resolve the service issue, submit a complaint through the DOT route and attach the relevant correspondence. Keep copies of everything you upload.
Frequently asked questions
Can an airline give me a voucher instead of a refund?
If a covered airline cancellation or significant modification gives you a refund option and you don't accept the alternative, don't assume a voucher is your only choice. Ask for the applicable refund in writing and review any credit terms before you accept them.
Do I automatically get a refund if I decide not to fly?
Not necessarily. A voluntary cancellation is generally evaluated under the fare conditions and the policy of the airline or ticket agent. Check those terms before you cancel.
Should I contact the airline or the travel website?
Contact both when a third party sold or issued the ticket. The airline controls the flight, while the seller may control parts of the booking or refund workflow.
Where do I complain about poor airline service?
Start with the airline's customer-service channel for an immediate response. For a federal service complaint in the United States, follow the DOT Aviation Consumer Protection route identified by the FAA.
What should I do first if my bag doesn't arrive?
Report it to the airline's baggage desk promptly, obtain the file reference number, track the bag, and preserve receipts and communications. Then follow the airline's claim instructions and deadline.
Open the booking, confirm whether it shows an airline cancellation, a significant modification, or a customer cancellation, and send a written request that matches that record before you accept a credit or walk away from the ticket.
