A mistake fare (error fare) is a published ticket price that is far below what the airline intended — usually from a system glitch such as a dropped zero, mapping error or missing surcharge — and may last only minutes.Keep reading: Mistake Fares & Error Fares: How to Find and Book Them

Mistake fares are not ordinary sales, Black Friday-style promos, or predictable midweek dips. They look absurd next to neighbouring dates. Honour after ticketing is common but not guaranteed; airlines may void some tickets. The practical playbook is book on a real checkout, do not phone the airline to “ask if it is allowed”, wait for e-ticket numbers, and delay non-refundable hotels. Full guide: mistake fares complete guide.

Error fares differ from hidden-city ticketing: you intend to fly the whole ticketed journey. They sometimes involve a dropped fuel surcharge. Everyday cheap-flight skill still matters more year-round — 21 ways to fly cheaper.

What should you do if you spot a mistake fare?

Screenshot the total, book passport-accurate names immediately, avoid calling the airline to confirm the glitch, wait for ticket numbers, then keep hotels cancellable for a few days.

Example: a long-haul economy checkout shows £180 while adjacent dates are £700 with the same stops. You complete payment, save the confirmation, and do not announce the PNR publicly before ticketing. If voided, stop non-refundable spend and read the OTA/airline refund path. Timing habits for normal fares: best time to book flights.

Award glitches exist too — same speed rules, plus transfer partner irreversibility if you already moved points.

What should you do in the 72 hours after booking a mistake fare?

Book instantly, then go quiet: no calls to the airline, no non-refundable hotels for at least a week, and watch for a cancellation email — most mistake fares are honoured, but the minority that die usually die within days.

Mistake fares reward speed and punish hesitation, because pricing errors live for hours, not days. Book first and analyse later — most jurisdictions give you a 24-hour free cancellation window anyway, which converts the decision into a free option. Pay by credit card, screenshot the confirmation and fare rules, and save the booking email in a folder you can find under pressure.

Then practise discipline. Do not phone the airline to “confirm it is real” — calls from excited buyers are how borderline errors get noticed and killed. Do not bolt non-refundable hotels, tours or positioning flights onto the trip immediately; give it one to two weeks. Airlines that cancel mistake fares almost always do so within the first few days, with a full automatic refund.

If the fare is honoured, it usually stays honoured — airlines swallow most errors because mass cancellations create worse press than the lost revenue. When a cancellation does come, know your leverage: some regulators require carriers to honour tickets after travel has begun or reliance costs were incurred, which is why the waiting period matters.
