For years, an airline that canceled a flight could steer a passenger toward a travel credit or voucher by default, leaving many travelers to assume that was the only option on the table. A Department of Transportation rule changes that assumption directly: when an airline cancels a flight, the passenger is entitled to a refund in cash or their original form of payment, and the airline cannot substitute a voucher or credit unless the passenger affirmatively agrees to take one instead.
What actually counts as a refund-triggering cancellation
DOT’s consumer guidance states plainly that a consumer is entitled to a refund “if the airline cancelled a flight, regardless of the reason,” as long as the passenger declines to travel or to accept the credits, vouchers, or other compensation the airline offers instead. The “regardless of the reason” language matters: the entitlement doesn’t depend on whether the cancellation stemmed from weather, a mechanical issue, or a staffing shortage — if the airline canceled the flight and the passenger doesn’t want the alternative being offered, cash is owed.
The same refund right extends beyond outright cancellations to flights the airline significantly changes, with DOT defining specific thresholds rather than leaving “significant” to each carrier’s discretion: a departure or arrival shifted three hours or more domestically, or six hours or more internationally, a change to a different departure or arrival airport, an itinerary with more connections than originally booked, or an involuntary downgrade to a lower class of service. Any one of those triggers the same underlying refund entitlement as a full cancellation.

Before this rule, the practical burden fell on the passenger to track down a refund request, often through a maze of website forms or lengthy phone holds. DOT’s rule flips that: if a passenger rejects an airline’s rebooking or credit offer, or simply doesn’t respond to it, the refund “must be issued to you automatically without you having to make a request,” and it has to land within 7 business days for a credit card purchase or 20 calendar days for other payment methods, counted from when the airline learns the passenger isn’t taking the alternative.
The “cash or original form of payment” requirement closes off the industry’s previous default of steering passengers toward store-credit-style vouchers. DOT’s original 2024 rule announcement was explicit that airlines “may not substitute vouchers, travel credits, or other forms of compensation unless the passenger affirmatively chooses to accept alternative compensation,” a reversal of the prior dynamic where a credit was often what a passenger got unless they specifically pushed back and asked for money.
The refund also has to be complete, not partial. DOT requires airlines to return the full ticket price for the unused portion of the trip, including government-imposed taxes and fees and any airline-imposed fees, regardless of whether those fees are separately refundable to the airline itself. A passenger isn’t supposed to absorb a partial loss on taxes or add-on charges just because the airline, not the passenger, caused the disruption.
Even when an airline does offer a voucher or travel credit instead of cash, and a passenger chooses to accept it, DOT’s rule sets a floor on how usable that credit has to be: it must remain valid for at least five years from the date it’s issued, and the airline has to disclose any material restrictions or conditions attached to it. A credit that expires in 90 days or carries hidden blackout dates doesn’t satisfy the rule just because the passenger technically agreed to take it over cash.
Where the refund right narrows, and what stays on the passenger to prove
The entitlement isn’t universal. A passenger who chooses to fly on a significantly delayed or changed flight rather than seeking a refund isn’t owed one under this rule, and someone who simply misses a flight or holds a non-refundable ticket that operates as scheduled has no refund claim tied to this provision at all. The right is built around airline-caused disruption specifically, not traveler-caused changes of plan or ordinary dissatisfaction with the flight experience.
Baggage fees follow a related but separate track: a passenger is entitled to a refund of a checked-bag fee if the bag is declared lost or is significantly delayed, defined as more than 12 hours after a domestic flight’s arrival, but only after the passenger files a mishandled-baggage report with the airline. That paperwork step is the passenger’s responsibility, and DOT’s guidance is direct that the refund clock and eligibility both depend on that report being filed rather than assumed automatically the way a cancellation refund is.
Tickets booked through a travel agency add one more layer worth knowing before a cancellation happens: refund responsibility falls on whichever party is the “merchant of record” on the original charge, which can be the airline or the booking site depending on how the purchase was structured. A traveler who booked through a third party and assumes the airline alone owes the refund may find the agency, not the carrier, is who actually has to process it — a distinction worth confirming before a disruption occurs rather than during one.
