Mistake Fares: How They Happen, How to Find Them, and How to Book

In January 2026, United accidentally published business class fares from the US to Tokyo for $300 round trip. The normal price? $5,000+. It lasted 3 hours before they caught it — and they honored every ticket.

This isn't rare. Mistake fares happen multiple times per month across different airlines.

Why Mistake Fares Happen

The most common causes:

• Currency conversion errors — An airline prices a fare in the wrong currency (e.g., pricing a USD fare as if it were in Indonesian Rupiah)
• Fuel surcharge glitches — Forgetting to add the fuel surcharge, saving you $500-1,000 on international business/first
• Routing errors — A connecting itinerary gets priced at the direct flight rate
• Manual data entry — Someone types $200 instead of $2,000

How to Catch Them

Speed is everything. Most mistake fares last 1-4 hours. You need:

1. Alerts — Set up fare alerts on your most-wanted routes. Pointify's alert system monitors prices and notifies you when something drops abnormally.
2. Flexibility — Mistake fares rarely happen on the exact dates you want. Be ready to adjust your schedule.
3. Fast booking — Don't overthink it. Book first, plan later. Most airlines allow free cancellation within 24 hours.

Will Airlines Honor Them?

The DOT requires US airlines to honor ticketed fares, even mistakes. International carriers are less predictable — some honor, some cancel. But the odds are in your favor: most mistake fares get honored because the PR cost of mass cancellation is worse than the revenue loss.

Book the ticket, wait 48 hours, then start planning your trip.
