Passengers can get a cash refund, not a voucher, under U.S. Department of Transportation rules for canceled or significantly changed flights. The airline must pay promptly, and only if the passenger declines the alternative offered.

What Counts as a Significant Change
A flight change becomes a significant change — and triggers refund rights — when the departure or arrival time moves by more than 3 hours for domestic flights or 6 hours for international. A change in airport or increase in connections also counts, as does a downgrade in class of service.
Refund Timing and Form
Under DOT regulations, airlines must provide automatic refunds "promptly" for canceled or significantly changed flights that the passenger declines to take. For credit card payments, that means within 7 business days. For other payments, the DOT allows up to 20 days. Refunds for payments made by cash, check, or other non-credit card methods must be provided in the same form as paid.
Rebooking, Vouchers and the Passenger’s Choice
When an airline cancels a flight or makes a significant change, it may offer alternative compensations such as rebooking on a different flight, vouchers, or travel credits. However, the DOT says passengers are entitled to a cash refund "if the passenger chooses not to travel or to accept the airline's alternative" — even for flights booked with non-refundable tickets.
How to Ask for the Refund
If your schedule allows and you want to assert your right to a refund, one approach is to write directly to the airline asking them to provide a refund to the original form of payment, with no delays. Get the full refund by refusing any alternative transportation or compensation offered the DOT says. The DOT materials focus on refund entitlement rather than specific request processes for each carrier. Passengers may wish to check the airline’s own published refund policy.
What to Watch For in Airline Responses
In handling cancellations, airlines sometimes present voucher or credit offers as alternatives to refunds, without highlighting the right to an actual refund with a cancelation or significant change. The DOT warns passengers that if they proactively choose a credit or voucher without understanding their rights, the airline is allowed to give a credit that is good for five years before a cash refund is owed. Keep in mind that the airline’s obligation for an automatic refund, and the passenger’s right to decline other compensations, comes from federal law, not the airline’s stated policy.
