People search both "error fare" and "mistake fare" expecting two different things. They're not - they're the same phenomenon. Here's what's really going on and how to act on one without getting burned.
Are they actually different?
No meaningful difference. Both describe a fare published far below its intended price because of a mistake. If anyone draws a line, it's loose:
| Term | Loosely used for | Reality |
|---|---|---|
| Error fare | Currency conversion or technical glitches | Same outcome: an underpriced ticket |
| Mistake fare | Any airline/agency pricing slip | Same outcome: an underpriced ticket |
In day-to-day deal hunting, use whichever word you like - they point to the same opportunity. Our full playbook is in the mistake fares guide.
What causes them
- Currency conversion errors - a fare loaded in the wrong currency or with a bad exchange rate.
- Missing fuel surcharges or taxes dropped from the total by a filing glitch.
- Human keystroke errors - an extra zero in the wrong place, or a decimal slip.
- Technical/feed bugs between airlines and booking systems.
The result is the same: a ticket priced like a domestic hop that's actually a business-class long-haul. Which is exactly the territory of business-class mistake fares.
Will the airline honor it?
Sometimes yes, sometimes no. Airlines can cancel an obvious pricing error, and policies vary by carrier and country. Many fares are honored - especially smaller errors or ones the airline decides aren't worth the goodwill hit to cancel - but you should never assume. The safe mindset: treat the ticket as unconfirmed until it's issued and has held for a few days.
How to book one safely
- Move fast. Error fares get fixed within hours, sometimes minutes.
- Book directly with the airline when possible, and pay by card for protection.
- Don't add non-refundable extras - no hotels, tours, or hard-to-change connecting tickets yet.
- Wait for the ticket to issue and stabilize (a few days) before planning the rest of the trip.
- Don't call the airline to "confirm" - that can flag the error. Let it ride.
