A traveler does not have to accept an airline’s substitute flight after a significant delay or change. When the passenger rejects the alternative and does not travel, the unused ticket must be refunded to the original payment method. For a credit-card purchase, federal rules require the airline to issue that refund within seven business days.
The refund depends on declining the alternative trip
The Department of Transportation’s current refund page says a passenger is entitled to a refund when the airline cancels or significantly changes a flight and the passenger chooses not to accept the offered alternative. Taking the rebooked flight generally ends the right to a full refund based on that disruption.
The domestic significant-delay threshold is generally three hours, while the international threshold is six hours. Other changes can qualify, including a different arrival or departure airport, additional connections in some circumstances, or a cabin downgrade. The itinerary and airline notice should be saved before accepting or rejecting the new plan.

Seven business days applies to credit-card purchases
Airlines must issue credit-card refunds within seven business days after a refund is due. For cash, check or another form of payment, the federal period is 20 calendar days. The rule concerns the airline’s issuance; a bank’s posting process can add time before the credit appears on the statement.
The refund should cover the unused transportation and fees for unused optional services. A paid seat assignment, checked-bag fee or upgrade that was not provided because the passenger rejected the changed trip belongs in the request. A voucher is not the same as a refund to the original form of payment.
The passenger should make the choice explicit
An airline app may automatically display a substitute itinerary. The traveler should state in writing that the significant change is rejected, no alternative transportation will be taken and a refund to the original payment method is requested. Screenshots of the original itinerary, changed schedule and confirmation preserve the trigger.
DOT’s airline dashboard summarizes additional customer-service commitments, but those voluntary promises are separate from the refund right. Meal or hotel commitments may depend on whether the disruption was within the airline’s control; the unused-ticket refund does not require the same cause.
A travel credit can carry restrictions that cash does not
Credits may expire, be limited to the named traveler or require booking directly with the carrier. Accepting one voluntarily can make sense when it carries added value, but a traveler entitled to a refund should compare the conditions before clicking. An airline should not substitute a voucher merely because it is operationally easier.
Tickets purchased through an online travel agency can involve an intermediary, yet the payment record still identifies who charged the card. The passenger should send the request through the seller’s documented channel and keep both the airline and agency responses when each points to the other.
Missing refunds can be escalated with a clean timeline
After seven business days, the traveler can follow up with the carrier using the original case number and credit-card statement. A card billing dispute may have its own deadline, so it should not be postponed indefinitely while the airline promises to investigate. The requested amount should be itemized by fare and unused fees.
DOT accepts complaints through its air-travel complaint form. A strong submission includes flight numbers, dates, the schedule change, proof that rebooking was rejected, the payment method and the unanswered refund request.
The travel decision controls the money right
The federal rule gives a passenger a choice after a qualifying disruption: accept the airline’s alternative and continue the trip, or reject it and receive the unused value back. It does not ordinarily allow both the substitute transportation and a full refund for the original ticket.
The DOT page confirms the important household deadline attached to that decision. When a significant delay is rejected and the ticket was bought by credit card, the refund is due within seven business days. Making the rejection clear and preserving the itinerary prevents the core facts from being lost in customer-service exchanges.
Travelers with connecting flights should ask whether the refund covers the entire unused itinerary or only a segment, especially when continuing the trip no longer serves its purpose. DOT guidance recognizes refunds for the unused portion; the original ticket and rebooking proposal show what transportation was actually declined.
