Secret Flying & Error Fares: How to Book Ultra-Cheap Flights (2026)
✈️ Flight Hack Spec Card
Quick Steps & Summary
Full Flight Hack Guide
Quick Answer (TL;DR)
Error fares, also called mistake fares, happen when an airline or booking site publishes a ticket at a very low price by accident. Secret Flying is a deal site that finds these fares and alerts travelers. Error fares can disappear within minutes, so you need alerts turned on and a quick decision. After booking, keep all other plans refundable until you have a confirmed ticket number, because the airline can still cancel the fare.

What Are Error Fares and Why Do They Happen?
Airline pricing runs through complex systems that combine automated tools and manual input. Occasionally something goes wrong, and a fare appears at a fraction of its normal price.
Common causes include:

How Secret Flying Works
Secret Flying is not an airline and does not sell tickets itself. It tells you where cheap fares are and links you to booking partners, such as large booking sites.
When Secret Flying finds a deal:
1. It publishes the route, the dates, and the price.
2. It links to a booking site where you can reserve the fare.
3. It sends alerts through its website, email, app, and social channels.
Secret Flying's free plan includes access to economy error fares. Paid plans add more alert options, such as more departure cities and specific routes.

Step-by-Step Guide: How to Catch and Book Error Fares
Step 1: Turn On Real-Time Alerts
Error fares can last only minutes before the airline corrects the price. Sign up for Secret Flying alerts and choose the airports you can fly from. Secret Flying also runs a WhatsApp channel dedicated to error fares, so you can be alerted quickly.
Step 2: Check and Book Quickly
If a fare fits your dates, check the route, the dates, and the total price, then book. Do not wait for several days to decide, because the fare may disappear while you are thinking. Check the booking site's reviews if you have never used it.
Step 3: Pay with a Card
Use a credit card if you have one. Many card issuers offer dispute or chargeback protection, which can help if a booking goes wrong. Protection rules differ by country and card, so check your own terms first.
Step 4: Avoid Contacting the Airline
Many deal hunters advise against calling or emailing the airline to ask whether a fare is real, because it can draw attention to the error. Wait for your booking confirmation and ticket number instead.
Step 5: Wait Before Non-Refundable Plans
Secret Flying itself advises against booking hotels or other plans until the last minute, because there is a small chance the airline cancels the ticket. Wait until you have a confirmed e-ticket number, and many travelers wait a week or more before they book anything non-refundable.

Smart Booking Tactics and Pro Tips
1. Stay flexible: Error fares appear on specific routes and dates, so flexible travel plans give you more chances to use them.
2. Check entry rules first: Make sure your passport is valid and you meet any visa requirements for the destination before you book.
3. Consider nearby departure cities: If an error fare leaves from a city near you, a positioning flight can be worth it. Book that flight only after your error fare ticket is confirmed.
4. Save everything: Keep confirmation emails, the booking page, and screenshots of the fare and price. You may need them if the airline cancels the ticket.
5. Know that rules vary: In many cases airlines can cancel an obvious mistake fare and refund the ticket, but they are not always required to cover other costs. Rules differ by country. Flights that touch the United States may also offer a 24-hour free cancellation window, so check the fare rules.
6. Use more than one alert source: Secret Flying works well alongside Fly4free and Going, and our Skyscanner Price Alerts Guide covers alerts for routes you already have in mind.
