The short answer: when a carrier stops flying, run the ladder in order — automatic refund where one is still possible, then chargeback, then DOT complaint, then bankruptcy claim — and let your booking channel pick the route. Direct card purchase: the dispute names the airline charge. Travel-site booking: the dispute names whoever is on your card statement, because that entity is the merchant of record. Points booking: there is no card fare charge to dispute, so the bankruptcy claim queue is the main route. Measure the filing window from the scheduled service date, not the purchase date, but file as soon as possible anyway, because the written-notice window on your statement can close earlier. No rung on this ladder promises money back, and no date on this page is a refund date.
First, the automatic refund. For a carrier that is still operating, DOT requires it automatically; for a carrier in bankruptcy, DOT states the carrier may be temporarily prohibited from providing refunds or vouchers to conserve assets — so watch a promised refund, but do not let waiting for it eat the filing deadline. Second, the chargeback: for a card-paid ticket, a services-not-received dispute with your card issuer, filed in writing to the billing-dispute address on your statement, with the ticket or receipt, the used and unused segments if you flew part of the trip, and a statement that the airline is in bankruptcy and ceased all operations and the service was not received, requesting a credit under the Fair Credit Billing Act. Third, the DOT complaint, filed in writing with the Aviation Consumer Protection division, kept by reference number — a record, not a refund mechanism. Fourth, the bankruptcy claim, for whatever the earlier rungs did not return. The order is the advice: each rung narrows what the next rung can still claim, and keeping two recoveries for one loss is never allowed — if one rung pays, update the others at once.
Direct. The airline charged your card, so the airline is the merchant of record and the dispute names the airline charge. This is the strongest card route in a collapse, because nothing stands between you and the merchant that failed to fly.
Travel site or agent. Check the card statement first. DOT defines the merchant of record as the entity shown on the financial charge statement, and a merchant-of-record ticket agent is required to make proper airfare refunds when a flight is cancelled or significantly changed. Agent name on the statement means the dispute names the agent for the airfare. Airline name on the statement means the dispute names the airline charge, even though an agent arranged the booking. The split to keep exact: DOT states ticket agents are not responsible for ancillary or baggage fees even when the agent is the merchant of record for the fee — those fees must be requested from the airline, which for a stopped carrier means the bankruptcy claim rung for the fee portion. Filing the airfare dispute against the wrong name wastes the filing window, so the statement check comes before the filing, not after.
Points or miles. See the points section below — the short version is that miles are not a card charge, so the claim queue, not the card dispute, is the route for them.
Two clocks run on a collapse case, and they do not agree. The network clock, for services not received under Visa dispute condition 13.1 and Mastercard dispute condition 4853, is 120 calendar days from the transaction processing date or from the last date the service was expected, capped at 540 calendar days from the transaction processing date. For a flight, the expected-service date is the scheduled flight date — a ticket bought months ahead is measured from the flight, not the purchase, and the checker on the carrier-collapse checker computes exactly that date, including the 540-day cap when a purchase date is given. The second clock is the statement clock: DOT's bankruptcy guidance says the credit-card claim must generally reach the issuer within 60 days of the first statement listing the charge, although issuers sometimes waive that deadline for future transportation. For a flight booked months ahead, the statement clock can close before the network clock does. No waiver is assumed anywhere on this site. The practical rule is blunt: file as soon as possible, and never wait for either date to arrive.
Two more clock notes. Debit cards have no promised window in DOT's guidance at all: DOT states only that some debit issuers voluntarily provide protections, so the issuer's answer, not a calendar, decides a debit case. And a non-card payment has no card dispute at all — the complaint and the claim are the whole ladder there.
Bankruptcy does not automatically mean collapse. DOT's bankruptcy guidance draws the line explicitly: a carrier may reorganize and keep operating, or stop operations through liquidation. For an operating carrier, the DOT automatic-refund rule applies in full — refund due within 7 business days for credit-card purchases and 20 calendar days for other payment methods after the refund becomes due, for a flight to, from, or within the United States that is cancelled or significantly changed where the passenger declines to travel or accept credits, vouchers, or other compensation. For a liquidated carrier, DOT states bankruptcy law may temporarily prohibit refunds or vouchers to conserve assets. Treating a stopped carrier as if the 7-day rule still bound it — waiting a fixed number of days for money from a company that no longer flies — is the most expensive mistake in a collapse case. If your carrier is still operating and cancelled one flight, stop here and use the cancelled-flight guide, which covers that case including its significant-change definitions; this guide deliberately does not repeat them, because collapse cases do not turn on them.
A points booking splits into two amounts that must never be merged. The miles portion has no card charge behind it, so no card dispute can return it: the route is the bankruptcy process, where DOT states passengers rank as general unsecured creditors and, after priority debts are paid, each may receive only a small fraction of what was owed. No figure beyond that phrase is stated here, because DOT states no figure beyond it. The card-paid portion — taxes or fees charged to a card on the award ticket — is a card charge for a service not received, and the issuer question applies to that portion only, measured from the scheduled service date like any other card charge. Keep the two amounts apart in every filing: miles in the claim, card-paid fees in the issuer question. A dispute filed for the miles value can be rejected on the ground that no card charge exists for it.
File the DOT complaint in writing with the Aviation Consumer Protection division, against the carrier and, where relevant, the agent, and keep the reference number. A complaint does not itself extract money from a liquidated carrier, and waiting for a DOT reply before filing a chargeback lets the filing deadline run — the complaint and the chargeback run in parallel. The bankruptcy claim is the last rung: find the carrier's official bankruptcy case and claims process, and claim only the amount not recovered by refund or chargeback. DOT's warning about the queue is the whole story in one sentence: your claim is considered alongside many other creditors, some of higher priority, and the remaining money goes to general unsecured creditors such as passengers, each of whom may receive only a small fraction of what was owed. If a chargeback later pays, update the claim at once. If you bought travel insurance, contact the insurer in parallel — DOT lists insurance as a parallel route, under the same no-double-recovery rule.
Watch for one, but do not wait for it past the filing deadline. DOT states a carrier in bankruptcy may be temporarily prohibited from providing refunds to conserve assets, so a promise from a liquidated carrier is not the same as a refund from an operating airline — and the operating-airline 7-day timing does not apply here.
Whoever is on your card statement. DOT defines the merchant of record as the entity shown on the financial charge statement, and the merchant of record is responsible for issuing the refund when one is due. Agent name means the dispute names the agent for the airfare; airline name means it names the airline charge. Ancillary and baggage fees go to the airline in either case.
Under the network framing, generally 120 calendar days from the scheduled service date, capped at 540 calendar days from the transaction processing date — but DOT's bankruptcy guidance says a credit-card claim must generally reach the issuer within 60 days of the first statement listing the charge, sometimes waived for future transportation. File as soon as possible; do not rely on a waiver, and never treat the computed date as a refund date.
Not for the miles: there is no card charge behind them. The bankruptcy claim queue is the route for the miles, where DOT states passengers may receive only a small fraction of what was owed. Only a card-paid taxes-or-fees portion can go to the card issuer as a separate question.
No. That timing applies to operating airlines. For a carrier in bankruptcy proceedings, DOT states bankruptcy law may temporarily prohibit refunds — the 7-day rule is not a lever against a liquidated carrier, which is why the chargeback and claim rungs exist.
