15 proven strategies to find cheap flights every time. From flexible date searching to error fares, learn how to save hundreds on your next flight booking.
Finding cheap flights isn't about luck — it's about knowing where to look, when to book, and which tools to use. After years of tracking flight prices and booking deals across dozens of platforms, these are the 15 strategies that consistently save travelers hundreds of dollars. Whether you're booking a weekend city break or a round-the-world trip, these tactics work.
This is the single biggest factor in flight pricing. Moving your departure or return by just one or two days can save 20-40%. Use the flexible date search on Google Flights or Skyscanner's whole-month view to spot the cheapest combinations. Midweek flights (Tuesday-Thursday) are typically cheapest for leisure routes, while weekend flights are cheapest for business routes.
No single search engine finds every deal. Start with Google Flights for speed and accuracy, check Skyscanner for broader OTA coverage, and use Kiwi.com for creative multi-carrier routing. Each platform has different airline and OTA partnerships, so comparing across all three catches deals the others miss.
Rather than checking prices obsessively, set up alerts on Google Flights and Skyscanner for your target routes. You'll get notified when prices drop. Google Flights' price tracking is particularly good — it monitors your route and emails you when fares decrease significantly. For maximum coverage, set alerts on both platforms.
The mythical 'best day to book' doesn't exist in a universal sense, but research consistently shows that booking 6-8 weeks ahead for domestic flights and 2-3 months ahead for international flights yields the best average prices. Last-minute bookings are almost always more expensive for leisure travel. The exception: last-minute deals on tour operator flights can be excellent.
Shoulder season (the weeks between peak and off-peak) offers the best combination of reasonable weather and lower prices. For Europe, this means April-May and September-October. For Southeast Asia, May-October (rainy season) brings the lowest fares. School holidays and major events always spike prices — avoid them if possible.
Flying into or out of a secondary airport can save significantly. London has six airports; New York has three; Tokyo has two. Budget carriers often use secondary airports (Stansted instead of Heathrow, Beauvais instead of CDG). Factor in ground transportation costs — sometimes the savings disappear when you add a €30 bus transfer.
Direct flights command a premium. If you're willing to add a stop, connecting flights can be 30-50% cheaper. Kiwi.com excels at finding self-transfer connections that combine different airlines. Just make sure to leave adequate connection time (minimum 2-3 hours for international self-transfers) and understand that self-transfers mean you're responsible for rebooking if you miss your connection.
Airlines occasionally publish fares with pricing errors — dramatically lower than intended. Secret Flying, The Points Guy, and Jack's Flight Club track these deals. Error fares can disappear within hours, so you need to act fast. Most are honored, but some get cancelled. Book directly with the airline for the best chance of the fare being honored.
The widespread belief that airlines raise prices when you search repeatedly is mostly a myth. Modern flight pricing is driven by demand algorithms, not individual cookie tracking. That said, using incognito mode or clearing cookies takes 5 seconds and eliminates any doubt. More importantly, prices genuinely fluctuate throughout the day based on demand patterns.
For budget carriers especially, booking two one-way tickets (perhaps on different airlines) is often cheaper than a round trip. This also gives you more flexibility — fly out on Ryanair and return on easyJet. For full-service carriers, round trips are usually cheaper than two one-ways, so check both options.
Credit card points and frequent flyer miles can cover flights entirely, but redemption values vary wildly. The best value is typically on long-haul business and first class redemptions where the cash price is high. Use tools like AwardHacker to find the best redemption options across multiple loyalty programs. Transfer flexible points (Amex, Chase) to airline partners at the right moment.
Sometimes the cheapest way from A to B involves going through C. Flying London to Bangkok via Dubai on Emirates can be cheaper than flying direct. Open-jaw itineraries (fly into one city, out of another) can also save money and add variety to your trip. Kiwi.com and Google Flights both handle open-jaw and multi-city searches.
Some airlines guarantee to match or beat prices found on third-party OTAs. Booking direct also means easier changes and cancellations, direct customer service, and better protection if something goes wrong. After finding the cheapest price on a search engine, check the airline's own website — they sometimes offer exclusive web fares not available through intermediaries.
Flight prices can vary based on the country you're searching from, because airlines price differently for different markets. Some travelers report finding lower prices by searching from the country of departure or a lower-income country. A VPN can change your apparent location. This is a grey area — it works sometimes but isn't guaranteed, and some booking sites block known VPN IPs.
The biggest mistake in flight booking is waiting too long for a lower price. If you've found a fare that's within your budget and the date works, book it. Flight prices trend upward as departure approaches, and the 'perfect' deal may never materialize. A good fare today is better than a hypothetical great fare tomorrow that never appears.

Compare fares across booking platforms:
Tuesday and Wednesday are typically the cheapest days to fly domestically. For international flights, weekday departures (Mon-Thu) are usually cheaper than weekends. However, the specific route matters more than the day — always use flexible date search to compare.
For domestic flights, 4-8 weeks ahead typically offers the best prices. For international flights, 2-3 months is the sweet spot. Last-minute bookings are almost always more expensive for leisure travel. Booking too far in advance (6+ months) can also mean higher prices as airlines start with higher fare classes.
The 'Tuesday booking myth' has been largely debunked by data from flight price tracking companies. Airlines adjust prices based on demand algorithms, not the day you search. What matters more is the day you fly, not the day you book. That said, airlines do sometimes launch sales on Tuesdays, so it doesn't hurt to check.
Almost never for leisure travel. Flight prices generally increase as the departure date approaches because remaining seats become scarcer. The exception is tour operator charter flights and some ultra-budget carriers that may discount unsold seats. For the best prices, book in advance.
