Mistake Fares Flight Deals

✎ RoamLight Editorial📅 2026-01-01⏰ 7 min read

If you’re a budget traveler looking for the best deals on flights, you’ve probably heard of mistake fares, where airlines accidentally publish significantly lower prices. These fares can save you hundreds—even thousands—of dollars on your next adventure.

What Are Mistake Fares?

Mistake fares occur when airlines publish incorrect pricing due to technical errors, human mistakes, or unintentionally misconfigured systems. For example, a flight from New York to Tokyo might be listed at $100 instead of the typical $1,000, attracting savvy travelers who are quick enough to book before the error is fixed. The key to snagging these deals is being vigilant and acting fast, as these fares can disappear within hours.

To maximize your chances of finding these deals, you should set up fare alerts on platforms like Google Flights and Skyscanner. Consider joining fare alert communities on social media, such as the “Secret Flying” Facebook group, where members share the latest fare mishaps. Bookmark websites like Scott's Cheap Flights, which offer both free and premium alerts about mistake fares and other travel deals, ensuring you're among the first to know when a deal pops up.

How to Book Mistake Fares

Once you spot a mistake fare, act quickly. Most errors are corrected within hours, so it’s crucial to book immediately. Use a reliable payment method like a credit card that offers travel protections. This can be beneficial if the airline cancels your flight or attempts to refund your ticket instead of honoring the fare.

When booking, always double-check the airline’s policy regarding cancellations or changes. Some low-cost airlines might have stricter policies, while others may allow you to make changes for a fee. Make sure to note the fare conditions before you purchase. If you're unsure about the flight or the airline, consider booking directly through the airline's website, as this often provides better customer service in the event of issues.

Destinations to Seek Out Mistake Fares

Certain destinations are more prone to mistake fares, especially major international hubs. For example, cities like Bangkok, Barcelona, and Mexico City frequently feature round-trip mistake fares that can be snagged for under $300. Recent examples include flights from Los Angeles to Bangkok for just $290 (¥43,000) or from London to Barcelona for £50 (about $65). The best part? These prices often include taxes and fees, making them a total steal!

To catch these deals, monitor fare trend reports on websites like Kayak or Hopper, which can help you understand when to expect the best prices for specific routes. Additionally, consider traveling during off-peak seasons; for example, flying to Europe in late winter or early spring often yields better fare finds compared to the summer months when travel is at its peak.

Are mistake fares guaranteed to be honored by airlines?

Not necessarily. Airlines are legally allowed to cancel flights if the fare was published in error. However, many airlines choose to honor the fare as a gesture of goodwill, especially if you book quickly after the mistake is made. If you get a confirmation email, there’s a good chance your ticket will be honored, but it’s not guaranteed.

How do I know if a fare is a mistake?

Typically, if a fare is significantly lower than the usual price for that route (often by 50% or more), it may be a mistake. You can cross-check prices on multiple websites like Kayak or Expedia to see if the fare appears consistently. If you see an unbelievable deal, act fast—you could be on to a rare mistake fare!
