For years, getting money back after an airline scrubbed your flight meant digging through a carrier’s website, sitting on hold, or settling for a voucher you never asked for. Federal rules now say it should work differently. Still, the details matter, and a few of them have shifted since the rule was written.
The Department of Transportation’s refund rules cover more than the ticket price. They also cover when a changed flight counts as cancelled, how quickly the money has to arrive, and what happens with bag fees and add on services. Here’s what the rules require as of late 2026, and where they’re still in flux.
The Rule at a Glance
The DOT announced its final automatic refund rule on April 24, 2024, and published it in the Federal Register on April 26, 2024[1]. The timing of enforcement came in two steps. Key automatic refund requirements took effect on May 16, 2024, when the FAA Reauthorization Act of 2024 was signed, and the remaining protections became effective on October 28, 2024.[2]
The department summarized the standard in plain terms. Refunds must be automatic, prompt, in the original form of payment, and in the full amount paid.[2] Those four ideas run through everything else in the rule.
When a Cancellation Entitles You to Money Back
The rule gives cancellation a specific meaning. A cancelled flight is a covered flight with a specific flight number between a specific city pair, published in the airline’s reservation system at the time of sale, that the carrier doesn’t operate.[1] That definition is what ties your refund right to the flight you actually bought.
Your own choice matters too. You’re entitled to a refund if your flight is cancelled or significantly changed and you don’t accept the alternative transportation or travel credits the airline offers.[3] Before the rule, airlines were permitted to set their own standards for what kind of flight changes warranted a refund.[4]
What Counts as a Significant Change
A flight doesn’t have to be cancelled outright for you to qualify. The rule defines a significant change for the first time.[3] The DOT lists departure or arrival times shifted by more than three hours domestically and six hours internationally, a different airport, more connections, or a downgrade to a lower class of service.[4]
There’s also protection for travelers with disabilities. Connections at different airports, or flights on different planes that are less accessible or accommodating to a person with a disability, can qualify as well.[4] Airlines can be more generous than the minimum, since carriers are free to apply a shorter timeframe but can’t go beyond three hours domestically or six hours internationally.[5] If you accept the changed flight and fly it, DOT says you’re not entitled to a full ticket refund just because the itinerary changed.[6]
How Fast the Money Has to Arrive
The deadlines depend on how you paid. Airlines and ticket agents must issue refunds within seven business days of the refund becoming due for credit card purchases, and within twenty calendar days for other payment methods.[7] A notice should come first, because carriers must tell affected consumers they’re entitled to a refund when a cancellation or significant change occurs.[1]
Keep in mind that the deadline covers the airline’s processing. Some consumer guides note that it may take a few more days for the credit to appear on your statement, depending on your card issuer.[8] A refund that looks late on your statement may therefore still be on time under the rule.
Cash or Original Payment, Not a Voucher
The refund has to go back to where it came from. Airlines and ticket agents must refund in cash or the original payment method, such as a credit card or airline miles.[7] If you paid with miles, you should get miles back.
Vouchers are allowed only if you want one. Airlines may not substitute vouchers, travel credits, or other compensation unless the passenger affirmatively chooses to accept it.[4] The DOT pointed to the old problem directly, noting that many airlines gave a credit or voucher by default, so passengers couldn’t easily rebook on another carrier.[7]
How Much You Should Get Back
The standard is the full price you paid, with one adjustment. Airlines and ticket agents must refund the full ticket purchase price, minus the value of any portion of transportation already used.[4] So if you flew the first leg of a round trip before the return was cancelled, the used portion can be deducted.
One legal summary describes the refund as covering the full fare including taxes, bag fees, and ancillary fees.[9] The rule also expects airlines to speak up, since they must notify consumers of their entitlement to a refund of the ticket price and any ancillary fees, along with any alternative offer.[10]
Delayed Bags and Services You Paid For but Didn’t Get
The rule reaches past the seat itself. Passengers are entitled to a refund of the fee for an extra service, such as seat selection or inflight entertainment, if the airline doesn’t provide it.[3] The same logic applies to checked bag fees when luggage is badly late.
The bag timelines are specific. If you file a mishandled baggage report, you’re entitled to a refund of your checked bag fee if the bag isn’t delivered within twelve hours of a domestic flight arriving at the gate, or fifteen to thirty hours for an international flight, depending on flight length.[4] Under the rule, the airline that operated the last flight segment generally makes these refunds automatically under certain circumstances.[11]
Tickets Bought Through a Travel Agent
Booking through an agent changes who has to act and when. Airlines must provide prompt automatic refunds, while ticket agents must provide prompt refunds upon request when airlines cancel or significantly change flights and consumers don’t accept the alternatives.[12] In other words, the automatic part falls on the airline.
The agent’s duty depends on who took your payment. Ticket agents must provide refunds on request when they are the merchant of record, meaning their name appears on your credit card statement.[13] If you booked through an online travel site, check which name shows up on the charge.
The Flight Number Exception
This is the part of the rule that has moved the most. Under DOT’s refund rule, a flight given a different flight number than the one assigned at purchase is considered a new flight, and the original is treated as cancelled, making the consumer eligible for a refund.[14] Airlines objected, since renumbering happens often for operational reasons.
On December 5, 2025, DOT paused enforcement for renumbered flights through June 30, 2026, as long as the passenger is rebooked and the flight operates without significant change or delay.[15] Because the related rulemaking is still pending, the department extended the pause for an additional year from the date of its July 2026 notice.[16] DOT says the temporary enforcement discretion expires July 7, 2027.[6]
What Could Still Change
The pause is tied to a larger rulemaking. The DOT is working on a proposal called Refund III, which aims to reduce regulatory burdens by modifying the definition of a flight cancellation that entitles consumers to refunds.[16] It’s still pending, so the definition of a cancelled flight could be rewritten.
Some of the protections rest on firmer ground than others. One legal analysis notes that the statute contains the core refund obligations, including the seven business day and twenty day deadlines, and can’t be vacated through an Administrative Procedure Act challenge.[9] Separately, the DOT also shelved a proposed rule that would have required cash compensation for airline caused delays and cancellations in November 2025.[15] That proposal was about compensation, not refunds, so refund rights were unaffected.
What to Do if Your Refund Doesn’t Arrive
Start by checking the original form of payment and the deadlines above, then contact the airline in writing and keep a record of the cancellation notice, your receipt, and any offers you declined. If the airline doesn’t pay within the required window, you can file a complaint with the DOT’s Office of Aviation Consumer Protection through the department’s online consumer complaint form.
Include your booking details, the dates of the cancellation or change, and how you paid. If you paid by credit card, you can also dispute the charge with your card issuer for a service you didn’t receive.
