The 100-mile rule that decides whether US cardholders can claim a flight refund

What you recover when a flight is cancelled or an airline fails depends less on the carrier than on the card you paid with and where you bought the ticket. Section 75 makes a UK credit card issuer jointly liable on qualifying purchases over £100, with no geographic limit.

The US splits protection in two: a billing-error procedure with a 60-day notice window, and a claims-and-defenses route capped at the cardholder’s home state or within 100 miles. For most Asia-Pacific bookings, that cap is the difference between a statutory right and a voluntary one.

When an airline collapses, cancels a route, or simply never delivers the flight you paid for, the instinct is to chase the carrier.

That instinct is usually wrong. By the time an airline is in trouble it is often insolvent, unreachable, or beyond the reach of the courts in the country where you bought the ticket. The party that actually owes you money is the one you never think to call: your card issuer.

Both the UK and the US built a system on that idea. They built it very differently.

Britain went statutory. Section 75 of the Consumer Credit Act 1974 makes a credit card issuer jointly and severally liable alongside the merchant on a qualifying purchase, and it applies whether the problem is breach of contract or misrepresentation. No geographic test is attached.

The US split the same problem into two provisions that consumer guides routinely blur: a billing-error procedure with a 60-day clock, and a narrower claims-and-defenses route that only reaches purchases made in your own state or within 100 miles of your address.

Why the UK safety net is a statutory right, not a favour

Section 75 of the Consumer Credit Act 1974 does something no US provision does: it puts the credit card issuer on the hook jointly and severally with the merchant. Not a goodwill gesture, not a dispute process — a liability written into statute, covering breach of contract and misrepresentation alike.

The trigger is the price of the item, not the size of the payment. Anything priced above £100 and no more than £30,000 per single item qualifies, according to the Financial Ombudsman Service. Even a deposit paid on a credit card can pull the whole item into cover, so long as the item itself clears the threshold.

That word — item — does more work than most travelers realise.

Debit, prepaid and charge cards fall outside Section 75 altogether. Those cardholders are not left with nothing: chargeback is a voluntary scheme run by the card networks, and how long a transaction can be reversed depends on the scheme’s rules rather than a fixed statutory clock. Voluntary is the operative word.

Timing is generous by comparison. A Section 75 claim is not bound to a short statutory notice window, though issuers will want it raised sooner, and the longer you wait, the harder the evidence gets.

Then there is the chain. Section 75 depends on a link running from debtor to creditor to supplier. Drop an intermediary into the middle — a travel agent, a payment processor, a BNPL provider — and that link can weaken or break.

How readily it breaks is contested rather than settled, and it is the point where a UK claim that looked solid can stop being solid.

The US answer is two mechanisms, and only one has a map

American coverage gets described as though there were a single protection. There are two, and they do different jobs.

The first is the billing-error route. Under 12 CFR 1026.13 — part of Regulation Z, which implements the Fair Credit Billing Act — a cardholder who spots a mistake on a statement has 60 days from the first statement showing the alleged error to file written notice with the creditor. Miss that window and the procedural right is gone.

The second is claims and defenses, under 12 CFR 1026.12(c). This is what lets you raise against the issuer a claim or non-tort defense you could have raised against the merchant. It carries two gates: credit extended above $50, and a transaction made in the cardholder’s own state or within 100 miles of their address.

Both gates must be cleared; failing either one closes the federal claims-and-defenses route. Nothing inside Regulation Z picks up the slack.

That distinction matters more than it sounds. A billing error is a mistake in how the account was billed. Claims and defenses is a merchant-side failure the merchant would not resolve — an undelivered flight, a service never provided.

Consumer literature tends to run the two together, and travelers then file the wrong kind of notice against the wrong clock.

Read the two US statutory rows together and the split is plain: the billing-error provision carries no geographic condition at all, while claims and defenses is the only route in the whole comparison tied to where the purchase happened.

What the 100-mile rule does to an Asia-Pacific booking

A UK cardholder buying a Tokyo or Singapore flight is not undone by the carrier’s foreign base. The claim is brought against the UK credit provider, and that provider — not the airline — is the defendant.

For a US cardholder, the geography is decisive. A long-haul Asia-Pacific ticket is almost never bought in your home state, and it is almost never bought within 100 miles of your address. Both gates fail, and the federal route closes before you start.

So the protection a US cardholder enjoys is strongest exactly where the risk is lowest. A short domestic purchase can qualify for the federal route; the long-haul ticket that is most likely to go wrong usually cannot.

What is left is chargeback — the card networks’ own dispute process, administered by the issuer under network rules rather than statute.

A US traveler who fails the geographic test may still have chargeback available, though the scheme, the reason code and the issuer’s process — not a single federal clock — decide whether it applies and how long they have.

Nor does any of this guarantee recovery when the counterparty is an Asia-Pacific carrier or a regional agent. Nothing in the federal claims-and-defenses provision promises a refund when the booking crosses a border. Beyond chargeback, the practical answer often sits in contract law, an insolvency process, or a travel-protection policy.

Where these rights actually come from

The rules here come from statute and regulation, not from airline policy. Section 75 has sat in UK law since 1974, and when an issuer and a cardholder disagree about it, the argument can end up in front of the Financial Ombudsman Service rather than a court.

The US side is administrative. The Consumer Financial Protection Bureau writes and enforces Regulation Z, and both tracks sit inside it — one covering how a billing-error notice is filed and investigated, the other preserving qualifying merchant claims and defenses against the issuer.

The two sit a few lines apart in the same rule, which is exactly why they get conflated. But the conditions attached to the second are not terms an issuer chose to adopt. They are written into the regulation, and no airline, agent or card company can wave them out of the way.

What this means before you book

The practical ranking starts before you pay. If a fare might ever need to be disputed, put it on a credit card rather than a debit or prepaid card — and put it there directly, not through an intermediary whose role in the payment chain you cannot see.

UK readers have one more thing to watch: the per-item threshold. A booking assembled from separately priced components can clear the £100 bar in total and still fail it piece by piece. Check what the individual item costs, not what the invoice says.

US readers need to know which route they are on. A billing mistake goes through the notice procedure. A failed flight goes through claims and defenses, and if the purchase happened outside your home state, expect to be pushed onto chargeback.

File early rather than waiting for the airline to answer.

Then there is the unresolved part. From 15 July 2026, the FCA regulates covered interest-free BNPL as Deferred Payment Credit, with firms given six months from Regulation Day to apply for full authorisation. Being supervised is not the same as being liable.

The FCA’s own material stops short of promising blanket cover, and merchant-run deferred-payment agreements sit outside the lender scope altogether. How far that protection reaches depends on the structure of the arrangement, and the position is not yet settled.

Key terms

Section 75

Section 75 is a provision of the UK’s Consumer Credit Act 1974 that makes a credit card issuer jointly and severally liable with the merchant on a qualifying purchase. It covers breach of contract and misrepresentation, and applies to items priced above £100 and no more than £30,000. For a traveler, the value is that the claim runs against the card issuer rather than the airline, so a carrier’s collapse or foreign base does not by itself remove the right.

Regulation Z

Regulation Z is the US federal regulation, administered by the Consumer Financial Protection Bureau, that governs credit-card billing and consumer credit. It carries two separate protections: the billing-error procedure at 12 CFR 1026.13 and the claims-and-defenses provision at 12 CFR 1026.12(c). For a traveler, the two tracks are not interchangeable — one addresses how an account was billed, the other a merchant-side failure the merchant refused to resolve.

Chargeback

Chargeback is a dispute procedure run by the card networks, not a statutory right, through which a cardholder can ask the issuer to reverse a transaction. It is governed by network rules and the issuer’s process rather than by a single fixed legal clock. For a traveler, its weakness is that it is voluntary — the network and issuer decide, where a statutory claim would be a matter of right.

Deferred Payment Credit

Deferred Payment Credit is the UK regulatory label for buy-now-pay-later arrangements, in which a lender funds a purchase the customer repays later. From 15 July 2026 the FCA regulates covered third-party-lender agreements under this regime, with firms given six months from Regulation Day to apply for full authorisation. For a traveler, the distinction that matters is who funded the agreement, since merchant-run and brokered arrangements sit outside the lender scope.
