Everyone wants to save money on flights. But with prices changing every few hours, it can feel impossible. The truth is, how to find cheap flights is not about luck — it's about knowing a few simple tricks.
In this guide, we'll walk you through exactly what to do, step by step. From when to book, to which apps to use, to which airlines save you the most money.
When Is the Best Time to Book a Flight?
Timing is everything. Book too early or too late, and you'll pay more than you need to.
Here's a simple breakdown:
- Domestic flights: Book about 30 days before your trip. Average fares are around $228.
- International flights: Book 2 to 6 months ahead for the best prices. Last-minute international deals exist, but they're risky.
- Peak seasons (summer, holidays): Always book early — at least 3 to 4 months ahead.
Cheapest days to fly:
- Domestic: Depart on Monday, return on Wednesday
- International: Wednesday is cheapest for both departure and return
And no — booking on a Tuesday does NOT automatically save you money. That's a myth. What really matters is how far ahead you book.
Best Apps and Websites to Find Cheap Flights
Using the right tool makes a big difference. Here are the best ones:
- Momondo — Best overall. Shows baggage fees in results so you can compare true costs.
- Google Flights — Fast, clean, and has a great price calendar. Perfect for checking flexible dates.
- Skyscanner — Great for advance bookings. Has an "Everywhere" search feature to find the cheapest destination.
- KAYAK — Has a "Price Forecast" tool that tells you whether to book now or wait.
Pro tip: Set up fare alerts on any of these platforms. Enter your route, pick a price target, and you'll get notified when fares drop. This is one of the easiest ways to save without doing constant research.
Why Flexibility Is Your Best Friend
If you can be flexible with your dates or destination, you'll almost always find a cheaper flight.
Here's how:
- Flying Tuesday or Wednesday instead of Friday can save you 30–40% on domestic routes.
- Use Google Flights' Explore map — enter your city and it shows you the cheapest places you can fly to.
- Use Skyscanner's "Everywhere" search to discover surprise deals.

Simple Flight Booking Hacks That Actually Work
These small habits can save you real money:
- Use incognito mode when searching. Booking sites track your searches and may raise prices if you look at the same flight more than once. Private browsing stops that.
- Book directly with the airline. Third-party sites often add $10–30 in extra fees. Booking direct is also easier if you need to make changes.
- Mix one-way tickets from different airlines. Sometimes buying two separate one-way tickets is cheaper than a round trip on one airline. You can save $40–80 this way.
- Follow airlines on social media. Budget carriers like Spirit and Ryanair post flash sales that last only 24–48 hours. These deals can be 50–80% off normal prices.
Budget Airlines: Are They Worth It?
Yes — if you know what you're getting into.
Budget airlines are now a huge part of air travel. They operate over 35% of all scheduled flights worldwide, and their base fares are typically 40–65% cheaper than big carriers.
Just remember: budget airlines often charge extra for bags and seat selection. Even with those fees, you're usually saving 25–40% compared to full-service airlines.
Top budget airlines by region:
- North America: Southwest (2 free checked bags!), Frontier, Allegiant Air, JetBlue
- Europe: Ryanair (~€40 average one-way), easyJet, Wizz Air, Norwegian
- Asia-Pacific: AirAsia, IndiGo, Scoot, Jetstar
Long-haul budget options:
- Norse Atlantic Airways — Europe to the U.S. from just $99–199 one-way
- French Bee — Paris to New York or San Francisco, roughly 50% cheaper than Air France
Also consider alternate airports. Flying into a secondary airport (like London Stansted instead of Heathrow) can cut fares by 30–50%. Just check how far the airport is from the city first.

Use Points and Miles to Fly for Less
This is the part most travelers skip — and it's a big mistake.
Almost every airline has a free loyalty program. Sign up even if you only fly occasionally. Benefits often include:
- Early access to flash sales (sometimes 24 hours before the public)
- Free seat selection at check-in
- Faster customer service
If you use a travel credit card, you can earn points on everyday purchases like groceries and gas — then use those points toward flights. Cards like Chase Sapphire, Amex Gold, or Capital One Venture let you transfer points to multiple airlines, giving you more flexibility.
Smart tips for using points:
- Use miles for peak travel dates when cash prices are highest
- Watch for transfer bonuses when moving points to airline partners
- Time big purchases with credit card sign-up bonuses before a planned trip
Knowing how to find cheap flights isn't just about searching smarter — it's about building habits that keep saving you money trip after trip.
