Error Fare Flight Deals: How to Score Accidentally Cheap Flights

Airlines occasionally price flights by mistake, creating once-in-a-while deals like Europe for $200 round trip. Here is what error fares are, how to find them, whether they get honored, and how to book one safely.

Every so often, an airline accidentally prices a ticket far below what it intended — and travelers who move fast score flights at unbelievable prices. Europe round trip for $200, Hawaii for $150, even business class for the price of economy. These are error fares (also called mistake fares), and learning how they work can land you the cheapest trip of your life.

What Causes an Error Fare

Error fares are genuine pricing mistakes, and they happen in a handful of predictable ways:

•Currency conversion errors — an automated system miscalculates an exchange rate, often pricing a fare in the wrong currency.

•Missing fuel surcharges or taxes — international fees are accidentally omitted from the total.

•Coding mistakes — a fare loaded into the system drops a digit or applies the wrong rule.

•Fare-class mix-ups — business or first class is mistakenly published at economy pricing.

Because so much airfare is generated automatically across countless systems, these slip through more often than you might think.

Should You Book an Error Fare?

Book it if:

•✅ You can afford to potentially lose the fare value if the airline cancels

•✅ Your travel dates are flexible

•✅ The discount is substantial — 50 percent or more off normal pricing

Be cautious because:

•❌ Airlines can sometimes cancel error fares, though US Department of Transportation rules have made honoring them more common than it used to be

•❌ You might receive a travel credit instead of the flight at the error price

•❌ Booking non-refundable hotels or connections before the fare is confirmed is risky

The Golden Rules for Booking Safely

1. Book the flight first, ask questions later. Error fares vanish in hours, sometimes minutes. You can always cancel within the 24-hour window US carriers are required to offer.

2. Do not call the airline to "confirm." That only flags the mistake. Hold the reservation and wait.

3. Avoid non-refundable add-ons. Keep hotels and onward travel refundable until the airfare is rock solid — ideally until you have been ticketed and a week has passed.

4. Pay with a credit card for the protection it provides if the fare is cancelled.

5. Be flexible. Error fares rarely match your ideal dates exactly; flexibility is what makes them usable.

How to Find Error Fares

Error fares are unpredictable by nature, so the key is to be notified the instant one appears rather than hunting for them. FlyNYC monitors all three NYC airports around the clock and alerts subscribers within minutes of detecting an error fare or an unusually steep drop. Keep an eye on our live deals page and set an alert so you never miss one.

What to Do After You Book

•Wait until the airline ticket is issued (you will receive a ticket number, not just a reservation).

•Give it several days — most airlines that honor a fare do so within about a week.

•Only then book your non-refundable hotel, tours, or onward flights.

•If the airline cancels, US rules generally entitle you to a full refund; know your broader delay and cancellation rights too.

The Bottom Line

Error fares are real, they are thrilling, and a little patience plus the right alerts can turn one into the trip of a lifetime. Book fast, keep everything refundable until the fare confirms, and stay flexible.
