Error Fares Explained: How to Find Mistake Fares

Error fares (also called mistake fares) are the holy grail of flight deals—prices so low they seem impossible. And they are... until you book one.

What is an Error Fare?

An error fare occurs when an airline accidentally prices a flight far below its intended cost. These mistakes can happen due to:

• **Currency conversion errors:** Pricing in the wrong currency
• **Missing digits:** $890 instead of $8,900
• **Fuel surcharge glitches:** Accidentally removing or reducing fees
• **Human input errors:** Typos during fare filing
• **System glitches:** Technical errors in pricing software

Real Error Fare Examples

Here are some legendary mistake fares from recent years:

• **United Airlines to Hong Kong:** $50 roundtrip (normally $1,200+)
• **Singapore Airlines Business Class to Europe:** $800 (normally $6,000+)
• **Delta First Class to Hawaii:** $100 (normally $2,500+)
• **Lufthansa US to Africa:** $240 (normally $1,500+)

Will Airlines Honor Error Fares?

Here's the reality:

Most Airlines Honor Them

The Department of Transportation used to require airlines to honor ticketed prices, but rules have changed. However, most airlines still honor error fares because:

• Bad PR from canceling isn't worth it
• Legal challenges in some countries
• Customer goodwill matters

Tips to Increase Your Chances

1. **Book immediately**—don't wait
2. **Don't call the airline** to ask if it's an error
3. **Wait to book hotels/cars** until the ticket is confirmed
4. **Book flexible accommodation** in case it's cancelled
5. **Check your reservation** after 24-48 hours

How to Find Error Fares

1. Follow Deal Aggregators

Sites like NomadSteals, SecretFlying, and The Flight Deal catch error fares fast. The key is speed—most disappear within hours.

2. Set Up Alerts

• Google Flights for specific routes
• Scott's Cheap Flights or similar services
• NomadSteals newsletter for daily deals

3. Check at Odd Hours

Error fares often appear when US airlines are asleep:

• Late night Eastern Time
• Early morning before business hours
• Weekends

4. Monitor Social Media

Deal hunters share finds on:

• Reddit r/flights and r/churning
• FlyerTalk forums
• Twitter deal accounts

5. Use ITA Matrix

Google's ITA Matrix can help you spot pricing anomalies on specific routes.

Booking Strategies

When you find a potential error fare:

1. **Don't overthink it**—book first, ask questions later
2. **Use a credit card with travel protection**
3. **Screenshot everything** during booking
4. **Book one-way if nervous** (easier to dispute)
5. **Check multiple OTAs**—some might have the error, others might not

Warning Signs It's an Error

• Price is 70-90% below normal
• Other fare classes are normal but one is extremely low
• Only available on a few dates
• Appears suddenly and disappears quickly
• Multiple deal sites are reporting it

If the cheap price comes from exiting at a connection city instead of an airline pricing mistake, treat it as a different tactic. Read the hidden city ticketing guide before booking because the baggage, roundtrip, and disruption risks are not the same as a true error fare.

What If It Gets Canceled?

If your error fare is cancelled:

• You'll receive a full refund
• Consider filing a DOT complaint (rarely helps but worth trying)
• Learn from it and keep hunting

The Value Score Connection

At NomadSteals, error fares typically score 95-100 on our Value Score. When you see scores this high, it's often because we've detected pricing anomalies that could indicate a mistake fare.

For a deeper decision framework, compare the fare against our Value Scores guide before you book. If the same route also has normal fares available, use the flight price prediction tools guide to decide whether the non-error price is worth waiting on. If you want the fastest signal when a mistake fare appears, pair this strategy with our flight deal alerts setup guide.

FAQ: Error Fares

Are error fares legal to book?

Yes. Travelers can book publicly available fares, including fares that appear to be pricing mistakes. The risk is that the airline or booking site may later cancel the ticket and refund you, so wait for confirmation before booking nonrefundable hotels or tours.

How fast do mistake fares disappear?

Many mistake fares disappear within a few hours, and the best ones can vanish faster once deal communities start sharing them. Have your traveler details, passport information, and payment method ready so you can act quickly when a high-value fare appears.

Should I call the airline after booking an error fare?

No. Calling attention to the mistake can increase the chance that the fare gets reviewed before your ticket is fully confirmed. Book first, save your confirmation, then wait 24-48 hours before making other nonrefundable travel plans.

Stay Ready

Error fares reward the prepared:

• Keep your passport current
• Have flexible vacation days available
• Maintain credit card points as backup
• Be ready to travel on short notice

If the fare is for a departure within the next few weeks, use the last-minute travel deals guide to check baggage fees, schedule quality, refund risk, and hotel availability before you commit.

The next error fare could appear any moment. Will you be ready?
