Error fares are real. In 2024, a bug on Air Canada's website accidentally listed roundtrip flights from Vancouver to Tokyo for $287 — that's 70% off the normal $950 price. Hundreds of travelers booked before the airline realized the mistake. In 2023, a currency conversion glitch let people fly from Australia to the US for just $189 on what should have been a $1,200+ ticket.
These deals are rare, but they happen. And when they do, they sell out in hours — sometimes minutes. This guide teaches you exactly what error fares are, where to find them, and how to act fast enough to actually score one.
What Exactly Is an Error Fare?
An error fare (also called a "mistake fare" or "glitch fare") is a discounted ticket price that exists because of a mistake, not a promotion. The airline didn't mean to sell that $287 Tokyo flight. They made an error.
Error fares happen three main ways:
- Airline IT glitches: A software bug in the airline's booking system displays a lower price. Sometimes the data is corrupted, sometimes there's a database sync error.
- Currency conversion mistakes: An airline accidentally publishes a price in the wrong currency. They meant $950 but it shows as £287 (roughly $362 USD), or vice versa.
- Human error: A person at the airline incorrectly enters a fare into the system — they type $289 instead of $2,289, or forget to load the correct pricing for a new flight route.
Why Do Airlines Honor Error Fares?
Most of the time, airlines DO honor error fares once the ticket is issued. Why? Because:
- Legal compliance: In many countries, if a price is displayed on a website and a customer completes the purchase, that's a binding contract. Airlines can't unilaterally cancel.
- Brand reputation: If an airline cancels tickets from angry customers who booked an error fare, they face PR backlash. Reddit threads blow up. News outlets cover it. It's bad for business.
- It's rare enough: The financial impact of a few hundred error fare bookings is tiny for a major airline.
That said, airlines sometimes do cancel error bookings before the ticket is issued. The key is booking fast enough that the reservation goes through and you get a confirmation email before they realize the mistake and disable the price.

How to Spot Error Fares Fast
The hard truth: spotting error fares manually is nearly impossible. You'd need to check dozens of routes every hour. By the time a human sees an error, it's usually fixed.
Your best bet is automated alerts. Here's the hierarchy of tools:
1. Dedicated Error Fare Alert Services (BEST)
Aviasales is the gold standard. You can set up price alerts for your preferred routes, and they'll email you the moment a price drops to your threshold. Many error fares are caught this way because the system is continuously scanning.
Other services: Secret Flying, Going.com, The Flight Deal, Scott's Cheap Flights (now Cheap Air Scout). These sites have dedicated teams that monitor error fares and post them the second they're found.
2. AI-Powered Deal Platforms (BETTER)
This is where SnapClaps comes in. We scan 12 major airports every 15 minutes and flag anything 35%+ below the 90-day average price. Error fares are by definition 40–90% off, so they light up immediately on our system. You get an alert before the deal disappears.
3. Google Flights + Price Alerts (OKAY)
Set a price alert on Google Flights for your route. You'll get an email when the price drops significantly. It's not specifically for error fares, but it can catch them.
4. Manual Checking (RARELY WORKS)
If you manually check flight prices every day, you might spot an error fare. But by the time you notice it, it's probably already fixed. Error fares sell out in 1–6 hours.
How to Book an Error Fare (Before It's Fixed)
When you spot an error fare, you have a narrow window. Here's the playbook:
- Click immediately. Don't think, don't compare. Click the airline's website and add to cart.
- Fill in passenger details FAST. Use autofill if you have it saved. Don't make typos.
- Pay instantly. Use a saved credit card or Apple Pay / Google Pay for speed. Don't go back to check other options.
- Confirm the booking. Wait for the confirmation email. Screenshot it. Save the confirmation number.
From finding the deal to confirming the booking should take under 5 minutes if you're fast.
What if the Airline Cancels Your Booking?
If you got a confirmation email and then the airline cancels the booking, here's what to do:
- Contact the airline. Call their customer service with your confirmation number. Be polite. Explain that you booked at the price their website displayed, and you have a confirmation email proving it.
- Ask for a voucher or rebooking. Some airlines will honor the original price. Others will offer a flight voucher for the difference. Some will try to guilt you into canceling ("our mistake, we can't honor this"). Don't cave.
- Escalate if needed. If the agent says no, ask for a supervisor. Be firm: "I have a valid confirmation. Your system completed the transaction. This is a legal binding contract."
- Dispute the charge (last resort). If they refund but won't rebook, you can dispute the charge with your credit card company, claiming "unauthorized transaction" or "merchant error." The airline will probably give in rather than deal with a chargeback.
Most airlines honor error fares to avoid the headache. But some don't. Going in, understand the risk.
Best Routes for Error Fares
Error fares don't happen on every route. They're most common on:
- Long-haul international flights: Tokyo, London, Paris, Sydney, Dubai (high base price = big savings when it's wrong)
- Premium cabin: Business class error fares are rarer but bigger jackpots
- Less common routes: An error on LAX–JFK might get lost in noise. An error on SFO–Manila stands out more.
What NOT to Do
- Don't call the airline to "confirm" the price before booking. The moment you tip them off, they'll fix it.
- Don't brag about error fares publicly before you've flown. It attracts airline attention.
- Don't try to book multiple error fare tickets in different names. That's fraud. Book for yourself or immediate family only.
- Don't assume the airline will honor it. It usually will, but not always. Understand the risk going in.
The Bottom Line
Error fares are the Holy Grail of travel hacking. They're rare, they're fast, and they require you to act instantly. But if you're subscribed to the right deal alerts and you move fast, you can score a trip that would normally cost $1,000 for $300. That's real money.
The key is early notification + instant action. Use Aviasales or similar tools to get alerts the moment an error appears. The difference between booking in the first minute versus the fifth minute can be the difference between a confirmed trip and a cancelled booking.
