AI-generated conceptual illustration of choosing rebooking or a refund; it does not depict a specific flight disruption.
A canceled flight can leave you making an expensive decision on a small phone screen. The most useful first question is whether you still want the airline to get you to your destination, or whether the trip no longer works and you want the eligible fare returned.
Those choices lead to different outcomes. This guide covers the United States framework for scheduled passenger flights to, from or within the US, including covered foreign airlines. It is general consumer information, not advice about an individual legal claim. Rules checked October 6, 2026.
Start with the trip you still need
Before accepting an app’s proposed replacement, check its arrival date, airports and connections. An overnight arrival might save the ticket but defeat the purpose of the trip. An airport change can add ground transport costs. A new connection may be unrealistic for a traveler who needs assistance.
Write down your latest useful arrival time. Then compare the airline’s actual offer against that deadline. This keeps a tempting button labeled “accept” from making the decision for you.
Most airlines rebook canceled passengers on an available flight without an additional fare charge. You can ask about another carrier, but there is no blanket federal requirement that your airline place you on a competitor. Ask what is available before buying a second ticket yourself. DOT’s cancellation guidance.
When a refund becomes an option
If the airline cancels, the reason does not remove your refund entitlement when you decline travel and the offered alternatives to a refund. That includes a nonrefundable ticket. A significant schedule change can also qualify. Taking the changed or replacement flight generally means you do not also receive the airfare refund under these DOT rules. DOT refund guidance.
For a covered itinerary, the regulation defines significant changes to include:
- Departure from the origin at least three hours earlier domestically, or six hours earlier internationally
- Arrival at the destination at least three hours later domestically, or six hours later internationally
- A different origin or destination airport
- More connections or a downgrade in cabin class
- For a passenger with a disability, a changed connecting airport, or a substituted aircraft missing an accessibility feature they need
The arrival test concerns the itinerary’s destination, not simply a departure-board delay. The rule covers scheduled service to, from and within the US, including qualifying international itineraries with brief incidental foreign stops. It is not a worldwide rule for every flight on a US airline. 14 CFR Part 260.
For example, compare the original and replacement arrival times in the same destination time zone. Keep the original itinerary available; the current app view may show only the revised version.
A voucher is a separate decision
A future-travel credit may suit someone who already expects to fly again. Before choosing it, read the expiration, transferability and booking restrictions, and check whether the offered amount really compensates for those limits.
You do not have to take a voucher instead of a refund you are entitled to receive. Airlines must tell you about that refund right when offering an alternative. If you still want the replacement flight, respond before the airline’s acceptance deadline rather than assuming an automatic rebooking will remain available indefinitely. DOT’s explanation of alternative offers.
Know who should return the money
Look at the payment statement to identify the merchant of record. For an airline sale, qualifying refunds are automatic; when a travel agency is the merchant, request the eligible airfare refund from that agency.
DOT’s guidance specifies seven business days for credit-card refunds and 20 calendar days for other payment methods. The triggering point depends on the circumstances; for an agency, its clock starts when the airline confirms eligibility. Refunds normally return to the original payment method unless you agree otherwise. Save the rejection or refund confirmation and the promised processing date. DOT’s refund compliance guide.
If part of the trip has already been flown, ask for an itemized calculation of the unused transportation. Do not assume an interrupted journey produces a refund of every completed segment. Ask separately about paid extras that were not delivered.
Meals and hotels need another check
A fare refund and overnight assistance answer different questions. DOT’s dashboard compares airlines’ commitments for disruptions within their control, such as crew or maintenance problems. The promises vary, and airlines must follow the commitments in their customer-service plans. Weather-related disruptions do not automatically receive the same treatment. Airline cancellation and delay dashboard.
Ask the agent what caused the disruption, which assistance applies and whether the airline will arrange the hotel or approve reimbursement. If you pay out of pocket, keep receipts and written authorization where available. A refund does not itself promise to reimburse a more expensive replacement ticket or every expense caused by the interruption.
Save a small evidence packet
Keep the booking confirmation, original and revised itineraries, cancellation notice, accepted or rejected offers, payment record and receipts together. If the promised resolution fails, contact the airline or agency with the flight details, the outcome you requested and supporting copies. DOT also accepts unresolved air-travel complaints. DOT’s complaint guidance.
The aim is to make one informed transportation decision first, then track the refund or assistance that follows from it.
