Only one of the three carriers commonly named has a verified case. Etihad Airways let $187 round-trip U.S.-Abu Dhabi mistake fares stand in December 2014, before the rules shifted.
Since the DOT’s May 8, 2015 policy statement, an airline that cancels a mistake fare can avoid enforcement by proving the fare was a mistake and reimbursing verifiable reliance expenses. It must also refund the full purchase price. The Norwegian and South African Airways honored-fare claims remain unverified.
Many travelers who follow mistake fares can name three airlines that supposedly honored famous ones. Trouble is, only one of those names survives contact with a source. Etihad Airways is the name that holds up.
The other two carriers float through forums and deal sites without a single authoritative reference confirming an honored ticket. The story that actually holds up is one verified case, followed by a policy change that reshaped everything after it.
The more durable story sits one layer down. Etihad’s famous decision came before the U.S. Department of Transportation changed the ground rules. On May 8, 2015, the DOT announced it would stop enforcing the post-purchase price-increase ban for qualifying mistake-fare cases.
From that date, whether a traveler keeps an accidentally cheap ticket or gets a refund has depended less on an airline’s goodwill. It now turns on the fine print of a policy built on prosecutorial discretion.
The one honored case the record actually proves
In December 2014, Etihad Airways’ U.S.–Abu Dhabi fares fell as low as $187 round trip — a price that looked more like a domestic weekend hop than a Gulf itinerary. The airline let those tickets stand.
What mattered next was the airline’s call. Etihad absorbed the shortfall months before the DOT’s May 8, 2015 policy shift rewrote the playbook. That timing matters: the 2014 episode is a verified case of an airline choosing to eat a mistake, not one forced to by a regulator.
Two names that keep circulating — without a confirmed case
The working title of this idea originally named three carriers. Two of them fail the evidence test.
No authoritative source reviewed verifies that Norwegian ever honored a named 2015 mistake fare. The same gap applies to South African Airways: the widely repeated $300 Johannesburg fare has no confirmed honored outcome. The only related SAA example the research surfaced is a $72 business-class fare that reports say was not honored — which cuts against the premise rather than supporting it.
None of this proves an SAA or Norwegian honor case never happened. It means the record does not support presenting one as established fact. And no official tally exists that sorts which airlines voluntarily absorbed mistake fares and which cancelled under the 2015 policy. That remains an open question, not a figure anyone can responsibly print.

What happens if an airline cancels your mistake fare
Two separate obligations sit on the airline when it voids a mistaken ticket.
First, the money comes back. If an airline cancels a purchase because of a pricing error, it must refund the full purchase price, according to the U.S. Department of Transportation. No partial-credit dodge sits anywhere in the policy language.
Second, to keep the DOT from treating the cancellation as a violation of the post-purchase price-increase ban, the airline has to prove the fare was a mistake and reimburse consumers for out-of-pocket expenses they relied on. Those expenses must be reasonable, actual, and verifiable — the policy cites non-refundable hotel costs as a qualifying example, and the seller can ask for documentation.
The legal hinge that changed the default
Few consumers read the statute underneath these fights. 14 C.F.R. § 399.88(a) makes it an unfair or deceptive practice for any seller of scheduled air transportation — inside the United States, to it, or from it — to raise the price after purchase. That is the quiet reason a mistake fare’s survival so often turns on whether the itinerary touches U.S. soil.
The Mistaken Fare Policy Statement issued on May 8, 2015 operates inside that statute. The DOT’s Office of Aviation Enforcement and Proceedings framed the move as prosecutorial discretion, not a repeal: § 399.88 stays on the books, and a sale that does not qualify as mistaken remains bound by it.
The clearest documented precedent is the United Airlines Danish Krone episode. On February 11, 2015, United’s Denmark website listed fares at extremely low converted prices, as USA TODAY reported.
After United cancelled the tickets, thousands of consumers asked the DOT to review the matter. The Enforcement Office declined to act, citing among other things how many U.S. purchasers had worked the search process and set their billing location to Denmark. The May 8 statement, issued roughly three months later, answered the same question the United case had raised.
What this means for a traveler who books a mistake fare
The defensive read is simple. If an itinerary begins or ends in the United States, the DOT’s ban on post-purchase price increases applies, and the 2015 policy statement dictates how much latitude an airline has to cancel an erroneous price. Geography, not goodwill, tends to decide the outcome.
The forward picture is quieter than the 2015 headlines suggested. The notice remains listed in DOT aviation-consumer guidance as of September 28, 2026, and no final rule has replaced it in the reviewed record. Nor does any later DOT enforcement order deal with a carrier cancelling or honoring a mistaken fare. For now, a policy the DOT itself labeled temporary reads as the agency’s standing guidance.
Key terms
- Mistake fare
- A mistake fare is an airline ticket sold at a price far below what the carrier intended, the result of a pricing error rather than a deliberate discount. Such fares surface through airline booking systems and spread quickly across deal sites before the carrier can correct them. Under the DOT’s 2015 policy, whether a traveler keeps one now turns on whether the airline treats the price as a genuine error and refunds the purchase.
- 14 C.F.R. § 399.88(a)
- 14 C.F.R. § 399.88(a) is the federal rule that makes it an unfair or deceptive practice for a seller of scheduled air transportation to raise the price after a ticket is purchased. It applies to routes inside the United States, to it, or from it, and it carves out an exception for government-imposed taxes or fees that were properly disclosed. Its scope is why the DOT’s 2015 policy had to be written as enforcement discretion rather than a repeal — the rule itself never left the books.
- Mistaken Fare Policy Statement
- The Mistaken Fare Policy Statement is the DOT guidance, issued May 8, 2015, that tells the agency when it will decline to enforce the post-purchase price-increase ban against an airline that cancels a mistaken fare. It sets two conditions: the seller must show the fare was a mistake, and it must refund the purchase price and reimburse reasonable, actual, and verifiable reliance costs. Its practical reach is narrow: it changes only how the DOT enforces § 399.88, not the rule itself.
- Prosecutorial discretion
- Prosecutorial discretion is an enforcement agency’s power to choose which violations of a rule it will pursue and which it will let pass. The DOT used that framing in its 2015 mistaken-fare policy, declining to enforce § 399.88 in qualifying cases instead of repealing it. The practical effect is that an airline’s obligation to honor a mistaken fare depends on the agency’s willingness to act, not on any change to the underlying regulation.
Questions? Answers.
Do airlines have to honor mistake fares?
Under 14 C.F.R. § 399.88, a seller generally cannot raise the airfare once a consumer completes the purchase. But the DOT’s May 8, 2015 policy statement lets the agency decline to enforce that rule when the seller demonstrates the fare was a mistake and reimburses consumers for qualifying reliance expenses. It’s enforcement discretion, not a repeal — and a sale that doesn’t qualify as mistaken still binds the seller under § 399.88.
Which mistake fares have actually been honored?
The record verified here supports one name: Etihad’s December 2014 U.S.-Abu Dhabi error, with round trips as low as $187. The claims that Norwegian honored a 2015 mistake fare, and that South African Airways honored a $300 Johannesburg fare, aren’t confirmed by any authoritative source reviewed.
Does EU261 or UK261 require an airline to honor a mistake fare?
The evidence reviewed doesn’t establish that. EU261 and UK261 cover passenger rights when a flight is cancelled, delayed, or boarding is denied; nothing in the retrieved material creates a parallel requirement to honor an obviously erroneous fare.
