The most jaw-dropping flight deals aren't cheap economy seats - they're business-class tickets accidentally priced like economy. Fly lie-flat across an ocean for a few hundred dollars. Here's how these premium mistake fares happen and how to land one.
What is a business-class mistake fare?
It's a premium-cabin ticket published far below its intended price because of a pricing error - the same family as any error/mistake fare, just in business or first. Because premium fares are so expensive normally, the dollar saving is enormous: a $4,000 business fare slipping to $900 isn't unusual when one of these appears.
Where they come from
- Currency conversion errors on premium fares loaded in the wrong currency.
- Missing fuel surcharges or taxes - which are a huge chunk of a business-class total, so dropping them craters the price.
- Keystroke errors in fare filings (a misplaced digit on a high-value fare).
- Promo or fare-combination bugs that stack discounts they shouldn't.

How to book one safely
- Move immediately. High-value errors are corrected the fastest.
- Book direct with the airline when possible, and pay by card for protection.
- No non-refundable extras until the ticket is issued and stable for several days.
- Don't call to "confirm." Drawing attention can trigger a cancellation.
- Expect the higher cancellation risk - the bigger the error, the more likely the airline voids it. Stay flexible.
