What is a mistake fare?

Updated 2026-06-22 · 5 min read · Magellan Flights

Every so often a flight pops up at a price that looks like a typo — New York to Milan for $180, business class to Asia for the price of economy. Sometimes it is a typo. These are mistake fares, and catching one is the closest thing travel has to winning a small lottery. Here's how they work — and the catch.

Quick answer

A mistake fare (or “error fare”) is a flight accidentally priced far below normal — from a currency slip, a missing fuel surcharge, or a plain typo. They're real and often bookable, but rare, gone within hours, and not always honored, so book a refundable fare and don't make other plans until it's confirmed.

Mistake fare, in plain English

A mistake fare is exactly what it sounds like: a fare an airline (or its software) published by accident, priced well below what the route should cost. “Error fare” means the same thing. They can be 50%, 70%, even 90% off normal — which is why deal hunters chase them.

How mistake fares happen

Currency slip-ups — a fare loaded in the wrong currency or a bad conversion.
Missing fuel surcharge — a big chunk of the price simply doesn't get added.
Typos — a fare filed with a digit dropped.
System glitches — promo codes or pricing rules misfiring.

Are mistake fares legal? Will the airline honor it?

Booking one is perfectly legal — you're accepting a price the airline published. The catch is whether they'll honor it. Sometimes airlines quietly let mistake fares stand as goodwill; other times they cancel and refund them, and the rules around this have shifted over the years. So the golden rule: book a refundable fare, pay with a card, and don't buy non-refundable hotels or onward flights until the ticket is confirmed. If an airline cancels on you, the DOT's aviation consumer protection office is the place to understand your options.

How to catch one

Move fast — mistake fares often last only hours before they're pulled.
Watch a deal tracker rather than hunting manually — by the time a fare trends on social media, it's usually dead.
Don't add non-refundable plans until the airline confirms the ticket.
Be ready to be flexible on dates — you take the error fare's terms, not your ideal schedule (and if it's international, confirm your passport is valid).
