How to Find Cheap Flights: Save EXTRA 5.7% On Every Booking!

I’ve tried countless flight booking platforms, but Kiwi.com is hands down my favorite. Their user-friendly interface, flexible search options, and unique multi-city itineraries make it super easy to find the best flights and secret airfare deals. If you haven’t used it yet, I highly recommend trying it!

And just to be clear — this article is NOT sponsored by Kiwi.com. I’m sharing this because I genuinely love their platform, and I discovered a flights travel hack that lets you save 5-6% every time you book an air ticket.

It works like a charm, and I want you to take advantage of it too! Families or business and first-class travelers can easily save 100-200 dollars on a single trip! Read on to find out how to find discounted flights in 2025.

How to unlock an extra 5-6% discount on flights

This method works best on desktop computers, but not so much on smartphones:

1. Visit Kiwi.com and search for your perfect flight.
2. Start the booking process – select your flight, enter your passenger details, and move toward checkout.
3. Flight hack - Just before you confirm your payment, try to close the browser tab (just hover your mouse over the closing X).
4. 💥 BOOM! A pop-up will appear, offering you an instant 5-6% discount if you subscribe to their newsletter and complete the booking within 24 hours.
5. Accept the offer, complete your booking, and enjoy your cheap air ticket!

What if the discount doesn’t show up right away?

This trick may not work on the first try. Sometimes, when you attempt to close the tab, the pop-up won’t appear immediately. But don’t worry!

If the discount doesn’t show up, simply go back to the Kiwi.com homepage, start your search again, and repeat the process. It might take two or three tries, but in most cases, the pop-up will eventually appear, offering you the discounted plane ticket.

Visit the website directly by typing Kiwi.com in the address bar, or try clicking on this link. You never know what prompts Kiwi.com to offer the hacks to get cheap flights.

Two important tips to trigger the cheap air ticket:

1. Make sure you spend enough time on the site: Go through the booking process as if you’re serious about completing the purchase — select your flight, enter your personal details, and reach the payment section at the bottom of the page. Kiwi.com needs to think you’re right on the edge of booking and just need one final push to commit. That’s when they’re most likely to offer you the discount!
2. Try logging out and booking as a guest: Sometimes, logged-in users don’t get the pop-up because Kiwi.com already knows they’re frequent customers. By browsing as a guest, you increase your chances of triggering the exit-intent discount offer.

Check other retailers to find the cheapest air ticket

Even with the 5-6% discount, other websites may have even lower prices. Check the most popular air ticket booking sites to find the lowest price possible.

It's worth trying smaller sites too, as each booking platform uses different algorithms to find the cheapest air ticket. Sometimes, I find a ticket hundreds of dollars cheaper than even on Kiwi, using an alternative route.

• Skyscanner: Best known for quickly comparing prices across hundreds of airlines and travel agencies, excelling at finding the lowest prices through its flexible, easy-to-use search tools.
• Trip.com: Provides a competitive advantage through its extensive coverage of the Asian market, offering localized service, competitive prices, and strong customer support, particularly for flights within or to Asia.
• Expedia: Offers a comprehensive travel-booking experience by bundling flights, hotels, car rentals, and activities, providing convenience through its robust, trusted platform and frequent deals.
• CheapOair: Specializes in budget-friendly fares, often providing exclusive discounts and promotional codes, particularly attractive for last-minute bookings and budget travelers.
• eDreams: Stands out by offering dynamic package deals and flight-hotel combinations, often displaying significant savings through flexible itinerary management tools.
• Cheapflights: Primarily excels at aggregating deals and discounts from multiple travel agencies, providing quick access to the latest low-cost and last-minute flight offers.
• Momondo: Differentiates itself through its strong emphasis on price transparency, using a user-friendly interface that clearly highlights cheaper travel dates and alternative routes.
• Kayak: Excellent at aggregating and comparing extensive travel data with powerful filtering tools, and it uniquely predicts airfare trends, helping travelers determine the optimal booking time.
• Bravofly: Offers a streamlined user experience with a strong focus on European low-cost airlines, making it particularly appealing for budget travelers in Europe.

Extra travel hacks for flying in 2025

Finding inexpensive flights isn’t just about luck — it’s about knowing where, when, and how to book. While the Kiwi.com hack is an excellent trick to find affordable flights, there are plenty of other insider tips and strategies that can help you save hundreds of dollars on airfare. Here’s how to find the cheapest flights to anywhere every time you book in 2025:

1. Be flexible with your travel dates and destination

If you want to know how to search for cheap flights, one of the easiest ways to find affordable airfare deals is to stay flexible with your travel dates. Airfare fluctuates daily, and prices can drop drastically depending on demand. Instead of picking exact dates first, try this method:

• Use Google Flights, Skyscanner, or Kiwi.com to search flights for an entire month and see which dates are cheapest.
• Consider traveling midweek (Tuesdays, Wednesdays, and Saturdays) — these are often the cheapest days to fly.
• If you’re open to different destinations, use the ‘Everywhere’ search on Skyscanner to find the best deals worldwide.

2. Book at the right time (Goldilocks Window)

The best time to book a flight varies depending on whether you’re flying domestic or international:

• Domestic flights: 1–3 months in advance (or 3–7 months for peak seasons like summer and holidays).
• International flights: 2–8 months in advance (or 4–10 months for peak travel periods).
• Avoid last-minute bookings: Prices usually skyrocket within three weeks of departure. If you want to know how to get cheap flights last minute, read the next point.
• DO last-minute!: Yes, it's a contradiction but you can find amazing flight deals if you book just 1-3 days in advance and the planes need to be filled up. This is a great trick for anyone wanting to know how to get cheap flights same day.

3. Set up flight alerts and track prices

Flight prices fluctuate daily, so don’t book blindly. Use Google Flights, Kayak, or Skyscanner to set price alerts. These tools notify you when fares drop for your selected route, ensuring you book at the lowest possible price.

4. Mix and match airlines & airports

Instead of booking a round-trip ticket with one airline, consider booking two separate one-way flights with different airlines — it can often be cheaper.

• Check nearby airports: Sometimes flying into or out of a nearby airport (instead of the main airport in a city) can save you money.
• Use positioning flights: If international fares are high, try to find a cheap domestic flight to a bigger hub (like New York or Los Angeles) and then grab a cheaper international flight from there.

5. Consider hidden city ticketing

Known as skiplagging, this is one of the sketchy airline hacks. It involves booking a cheaper flight with a layover in your actual destination and skipping the final leg. Use with caution:

• This only works with carry-on luggage — checked bags will be sent to the final destination.
• Airlines don’t like this flight trick and may cancel your frequent flyer account if caught.
• Use Skiplagged.com to find hidden city fares.

6. Use budget airlines & error fares

Low-cost carriers often have unbeatable deals, especially for short-haul and regional flights.

• Check budget airlines like Ryanair, Spirit, JetBlue, and AirAsia.
• Sign up for deal alerts from Going (Scott’s Cheap Flights), Secret Flying, and Dollar Flight Club to catch mistake fares and flash sales.

7. Consider alternative routes & layovers

Flying direct is usually more expensive. Instead:

• Book a layover: Sometimes, a flight with a stop in another city can be significantly cheaper.
• Use land travel: Instead of flying directly into a major city, fly to a cheaper nearby city and take a bus or train. Do not do this in the UK, though! Land travel is more expensive than flying.

8. Pay in a foreign currency

Sometimes, booking a flight in the airline’s local currency (instead of your home currency) can result in lower fares.

• Use Google’s currency converter to compare prices.
• Make sure your credit card has no foreign transaction fees before trying this.
• Get Revolut or Wise bank cards for the best international rates.

9. Take advantage of frequent flyer programs & credit card rewards

Frequent flyer miles and travel credit cards can help you fly for free:

• Join airline loyalty programs and accumulate points.
• Use travel credit cards to earn miles on everyday purchases.
• Look for bonus point promotions to maximize your miles.

10. Book flights as a single passenger first

One of the most common airline ticket hacks is when traveling in a group, search for one ticket at a time instead of all at once. Airlines sell tickets in fare classes, meaning if there’s only one cheap ticket left, the airline will bump the entire group up to the higher-priced tier.

11. Look for promo codes and airline sales

Many airlines and booking platforms offer discount codes:

• Check airline newsletters and social media for limited-time promo codes.
• Sign up for airline sales events, like Black Friday, Travel Tuesday, and Cyber Monday.

12. Book flight & hotel together

Some platforms, like Expedia, offer discounts when you book flights and hotels together. For example, you may find Caribbean vacation deals from the United States for as low as $249 USD per person, including a plane ticket and hotel for one week!

13. Book refundable tickets and rebook if prices drop

Many airlines allow free cancellations within 24 hours. If prices drop, cancel and rebook at the lower fare.
