How to Find Cheap Flights Using Error Fares

How I Scored $200 Flights to Europe Using Error Fares (And You Can Too)

The golden hour view from a seat I snagged for just $220 round-trip to Iceland.

✈️ Best time to monitor: Late night/early morning (12am-6am local time)
💰 Estimated savings: 60-90% off regular fares (round-trip deals from $150-400)
⏱️ How long to search: 10-15 minutes daily for 2-3 weeks
🎯 Difficulty level: Moderate (requires patience and speed)
📍 Recommended season: Year-round, but peak booking windows are January-February and September-October
👥 Best for: Solo travelers, digital nomads, flexible couples, and adventure seekers

I still remember the morning. My alarm went off at 4:47 AM. I groaned, checked my phone, and saw a notification from Scott's Cheap Flights (now Going.com). Subject line: "Mistake Fare Alert – New York to Milan, $180 round-trip." I blinked, rubbed my eyes, and assumed the price was a typo. It was. But that typo was a perfectly legitimate airfare glitch that lasted 3 hours before the airline caught it. I booked, and eight weeks later, I was eating the best gelato of my life in a piazza in Florence—for less than the cost of my weekly grocery bill.

I’m not a travel agent or a programmer who scrapes fare data. I’m just a guy who figured out that error fares—sometimes called mistake fares—are the single best-kept secret in budget travel. Over the last five years, I've used them to fly to Reykjavik for $220, Tokyo for $340, and Costa Rica for $120. Every single one was a pricing error the airline had to honor by law (in most jurisdictions).

In this guide, I’ll show you exactly how to find these glitches before they disappear, which tools to use, and how to avoid the common pitfalls that leave many travelers empty-handed. By the end, you’ll have a step-by-step system to book flights at 70-90% off—without luck or insider connections. Let me prove that those ridiculously cheap flights you see on Twitter aren't scams. They're real, and they're waiting for you.

The Essentials at a Glance

• ✈️ Best seats are in the first 15 minutes: Error fares disappear in under 8 hours. You must book immediately—not tomorrow.
• 🔔 Your phone is your weapon: Enable push alerts from Going.com (formerly Scott's Cheap Flights) and turn off "do not disturb" during peak glitch hours.
• 🧠 Don't check luggage initially: Cheap mistake fares often vanish if you add a bag. Book a basic fare first; add bags later at the airline's counter.
• 🌍 Be flexible with your departure city: A glitch from Newark (EWR) might not exist from JFK. Check airports within a 4-hour drive.
• 📅 Travel dates are non-negotiable: Airlines rarely honor error fares if you change the dates. Accept the given window or lose the deal.

The Complete Guide

Why This Matters / Why You Should Go

Let’s be honest: flying is absurdly expensive for most people. A round-trip to Europe from the US often costs $800-$1,200. That single ticket can eat up your entire travel budget before you’ve even booked a hostel. Error fares change that equation entirely. I’ve seen a mistake fare to Bali for $250 from the West Coast—that’s a price that effectively halves the cost of the whole trip. The reason these fares exist is simple: human error. An airline pricing analyst mistypes a currency conversion, forgets to add fuel surcharges, or sets a fare class to the wrong value. The system then sells tickets at that wrong price until someone catches it.

Why should you care? Because in the last three years alone, airlines have honored over 95% of valid error fare bookings (per the US Department of Transportation and similar EU regulations). That means if you book fast, you are almost guaranteed to fly. It’s not a loophole—it’s a technical oversight that becomes your legal ticket. This matters for anyone who wants to see the world without going into debt. Whether you’re a solo adventurer, a cash-strapped student, or a family of four trying to take one big trip, error fares can make destinations financially accessible that otherwise seem out of reach.

When to Visit (Seasonal Guide for Error Fare Hunting)

Error fares don’t follow traditional seasons, but the frequency of glitches does. I’ve tracked this for years. Here’s the breakdown:

Low season (January-February): This is the golden age of error fares. Airlines are recovering from holiday traffic, systems are updated carelessly, and human error spikes. I found my Milan deal on a January Tuesday at 3 AM. Expect 2-4 major mistake fare alerts per week during this period.

Shoulder season (September-October): After summer demand drops, airlines run less experienced staff and often mismanage fare uploads. Good window, but deals are 30% less frequent than winter.

High season (June-August): Fewer glitches. Airlines are more vigilant because demand is high. However, transpacific mistake fares (US to Asia) appear more often here due to complex route codes. I snagged a $330 flight to Japan in July this way.

Pro tip: The absolute best day of the week for error fares is Tuesday between midnight and 6 AM Eastern Time. Why? New fare sheets are uploaded Monday night, and errors are caught Tuesday morning. Book in that window.

Budget Breakdown

Let’s talk real numbers from my actual purchases. These aren’t theoretical averages; these are prices I paid:

• Flight (error fare): $180-$350 round-trip (international). Compare to typical $600-$1,200. Savings: $400-$900 per ticket.
• Accommodation (low/mid/high): Since you saved on flights, you can afford better lodging. Low: $30/night hostel; Mid: $80/night Airbnb; High: $180/night hotel.
• Food: $20-$50/day depending on destination. I often splurge because my flights were so cheap.
• Activities: $10-$40/day. Museums, walking tours, local experiences.
• Transport: $5-$15/day using public transit or rideshares.
• Total weekly cost (mid-range): $180 (flight) + $560 (7 nights lodging at $80) + $245 (food at $35/day) + $105 (activities) + $70 (transport) = $1,160 for a week abroad. Compare that to $1,500+ without the error fare.

Getting There & Getting Around

Error fares are usually offered by major international airlines (Delta, United, British Airways, Qatar Airways, etc.) at hub airports. You’ll most likely fly from a big city like New York, Chicago, Los Angeles, London, or Dubai. My experience: I drove 4 hours from my small town to Newark (EWR) because the glitch was available from that specific airport, not my local regional one. It was worth it. The flight cost me $180 round-trip to Milan vs. $700 from my local airport.

Once you land at your destination, getting around depends on the city. For European error fares, I always buy a regional rail pass in advance (like Eurail or individual country passes—about $50-100 for a week). For Asian error fares (like Tokyo), the metro and bullet train network is cheap and punctual. I use Google Maps offline and a local SIM card ($15 for 30 days with unlimited data from providers like Airalo). Driving is rarely necessary for error fare trips because you’re usually arriving in a major metropolitan hub.

Important note: When booking a mistake fare, avoid adding any domestic connecting flights onto the same itinerary until the price is ticketed. Agents often catch errors during multi-segment bookings. Book the international leg first, then separately book your domestic positioning flight.

Top Recommendations / Must-Do Activities

Because error fares make destinations suddenly accessible, here are my top three favorite trips I've taken using them, complete with personal perspective:

1. My $220 Reykjavik Trip: I landed at Keflavik International at 6 AM on a Thursday. The Blue Lagoon was overcrowded, so I rented a used car ($35/day from a local dealer) and drove to the secret hot springs at Reykjadalur—a 45-minute hike to a natural river hot tub. No crowds, no entry fee, just me and the steam. The mistake fare made this spontaneous adventure possible. Don’t just go to the tourist traps. Ask locals for the "hidden" geothermal spots.

2. My $340 Tokyo Adventure: I had 5 days. Jet lag hit hard, but I woke at 4 AM and walked to Tsukiji Outer Market before the crowds. The fresh tuna and tamagoyaki cost $8 total. The best part: I used Google Flights' "explore" mode to see where else I could fly from Tokyo for cheap. I ended up booking a separate $50 flight to Osaka for a day trip to see the deer at Nara. Error fares are a springboard for unexpected side trips.

3. My $120 Costa Rica Escape: This was a domestic mistake fare (San Francisco to Liberia) for $120. I rented a 4x4 and drove to Nosara. The surf was perfect, but the real magic was a night walk through the jungle with a guide I found on a WhatsApp group. Cost: $25 for a 2-hour tour. I saw tree frogs and a sleeping sloth. Error fares don't just save money; they remove the barrier to experiences you'd otherwise talk yourself out of.

Traveler’s Pro Tips

Tip 1: Use a dedicated error fare alert service with a trial: I've tried them all. The premium version of Going.com (formerly Scott's Cheap Flights) has a 14-day free trial. Use it, book a deal, then cancel. I paid $0 for the membership that got me my $180 Milan flight. The free tier works, but the paid version (about $49/year) alerts you within minutes—critical for glitch fares.

Tip 2: Always book directly with the airline, not third-party sites: If the airline makes a mistake and later refuses to honor the fare, you have more leverage if you bought directly from them. Third-party sites often refund you but won't fight for the ticket. I always use the airline's website or app.

Tip 3: Keep a "go bag" packed at all times: Error fare windows are often for travel within 2-6 weeks. I have a small duffel with three days of clothes, toiletries, and a universal adapter. When I booked my $220 Iceland trip, the travel dates were in 10 days. I was ready in 30 minutes.

Tip 4: Use a credit card with travel protection and no foreign transaction fees: If the airline cancels the error fare, a good travel card (like Chase Sapphire Preferred) can help you dispute charges. Also, you'll need immediate payment. I've had alerts at 3 AM, clicked "book," and my card was charged instantly. No hesitation.

Tip 5: Join private Facebook groups for mistake fares: Groups like "Error Fares and Flight Deals" often have humans posting finds faster than bots. I've gotten 3 deals from community posts that automated alerts missed. Speed is everything.

Common Mistakes to Avoid

Mistake 1: Waiting to "think about it." I once saw a $150 round-trip to Dublin. I told myself, "I'll book it after my meeting at 10 AM." By 9:30 AM, the fare was gone. Error fares have a half-life of about 2-4 hours. Book first, plan later. You can always cancel within 24 hours for a full refund (most airlines allow this).

Mistake 2: Checking luggage during booking. On my first error fare attempt, I added a checked bag during the booking process. The total jumped from $180 to $260. I hesitated, and the fare disappeared. Now, I always book the basic "personal item only" fare, then add bags later at the airport kiosk (usually $30-40 checked). Do not let the bag option eat your time.

Mistake 3: Not checking alternative nearby airports. I missed a $200 round-trip to Paris because I only searched from my local airport (Philadelphia). The glitch was from Newark (EWR), 90 minutes away. The consequence: I paid $700 a month later. Always search "All airports within 200 miles" on Google Flights before giving up.

Mistake 4: Booking with small, unknown airlines. A mistake fare on a major carrier like Delta or United is almost always honored. But a mistake fare on a budget foreign airline (like Wizz Air or Air Asia) is riskier. They may cancel and refund you without liability. I only book error fares on legacy carriers to minimize risk.

Your Travel Checklist

Before you start hunting error fares, set yourself up for success with this checklist:

• Documents: Scan your passport (make sure it's valid 6+ months from travel date). Keep a digital copy in your email.
• Packing: Pre-pack a small "go bag" with basics: underwear, socks, a light jacket, phone charger, universal adapter, travel-sized toiletries.
• Research: Know which airports near you are hubs for major airlines. Make a list: your top 3 departure airports and top 3 dream destinations.
• Bookings: Sign up for Going.com (free or trial). Register for at least 2 private Facebook error fare groups. Enable browser notifications.
• Health & Safety: Keep a travel insurance plan on file (like World Nomads) that you can activate instantly after booking an error fare.
• Local Currency: Pre-load currency on a Wise card. Moves at market rates, no fees. Do not rely on airport exchange booths.
• Apps: Download Google Flights, Going.com app, WhatsApp (for group alerts), and FlightAware (to track your booked error fare status).

Traveler FAQ

Q: Are error fares legal? Can the airline cancel my ticket?

A: Yes, they are legal. In the US and EU, once you have a confirmation number and the airline has processed payment, they are generally obligated to honor the ticket. I've had 8 error fares, and only 1 was cancelled (small airline). The airline refunded me, but I kept arguing and eventually got a voucher. Major carriers rarely cancel.

Q: How do I find error fares if I don't want to pay for alerts?

A: Use the free tier of Going.com and follow accounts like @SecretFlying and @Airfarewatchdog on Twitter. Turn on notifications for those accounts. Also, check Google Flights' "Explore" map and sort by "Cheapest." Sometimes error fares appear there before being flagged.

Q: Can I use error fares for a family trip with specific dates?

A: It's harder but possible. Error fares have fixed travel windows (often 1-3 weeks). If you need a specific week, you'll be less lucky. However, I've seen family fares (e.g., $400 round-trip to Mexico for 4 people) during off-peak windows. Book one ticket first, then try adding family members on the same confirmation—sometimes the glitch still works for multiple passengers.

Q: What's the difference between a mistake fare and a normal sale?

A: A normal sale is intentional. A mistake fare is an error—like a flight priced at $10 instead of $500, or a business class ticket costing less than economy. Sales are predictable (Black Friday, Cyber Monday). Error fares are random, last 2-8 hours, and generate 70-90% savings vs. 20-40% for sales.

Q: What happens if I book and the airline cancels my ticket the next day?

A: You get a full refund. But don't just accept that. Call the airline and ask for compensation: vouchers, miles, or rebooking at the error fare price. I once argued for 45 minutes and got a voucher worth $200 plus a free upgrade on a later booking. Persistence pays off.

Ready for Your Adventure?

There’s a paradox at the heart of error fare travel: the cheaper the ticket, the more valuable the experience. Because I paid only $220 to Iceland, I felt no pressure to cram my itinerary full of expensive tours. I sat in a geothermal pool for three hours, did nothing, and loved it. The freedom of a ridiculously cheap flight is the freedom to travel slowly, without the anxiety of "I have to make this worth the $1,000 I spent."

I know the hesitation. You think, "This is too good to be true." But I’m here to tell you: it’s true. I’ve done it over and over. The only real obstacle is speed. The next time your phone buzzes at 4 AM with a flight to somewhere absurdly cheap for a price that seems impossible, don’t overthink it. Open your wallet, book the seat, and ask questions later. The world is waiting, and it’s never been more affordable. Go get that error fare—I’ll see you at the gate.
