Airfare is often the single biggest expense of any trip, but it doesn’t have to drain your travel fund. Airlines use complex pricing algorithms, and once you understand how they work, you can consistently pay less than the average traveler. Whether you’re planning a weekend getaway to New York or a month-long adventure, these 17 proven tips on how to find cheap flights will help you keep more money in your pocket for the fun part of traveling.
WHEN TO BOOK FOR THE LOWEST FARES
1. Book Domestic Flights 1-3 Months Ahead
For US domestic routes, the sweet spot is typically 28 to 90 days before departure. Book too early and you miss fare drops; book too late and prices surge as seats fill.
2. Book International Flights 3-6 Months Ahead
International fares to Europe, Asia, and South America are usually cheapest 3 to 6 months out. For peak summer travel, start watching prices even earlier.
3. Fly on Tuesdays, Wednesdays, and Saturdays
Midweek flights are consistently cheaper than Friday and Sunday departures. Shifting your trip by even one day can save $50 to $150 per ticket.
4. Travel During Shoulder Season
Flying to Europe in late April or October instead of July can cut airfare nearly in half. Shoulder seasons also mean thinner crowds and milder weather.
SMART SEARCH STRATEGIES
5. Always Search in Incognito or Private Mode
Airlines and booking sites track your searches with cookies and may raise prices on routes you keep checking. Search in private browsing mode to see unbiased fares.
6. Compare Multiple Search Engines
No single site always has the lowest price. Check Google Flights, Skyscanner, and Kayak, then compare with the airline’s own website before booking.
7. Use Google Flights’ Price Tracking and Date Grid
Turn on price tracking for your route to get email alerts when fares drop. The date grid and price graph show you the cheapest days to fly at a glance.
8. Search One-Way Fares Separately
Sometimes booking two one-way tickets on different airlines is cheaper than a round-trip on one carrier. Always check both options.
9. Try Nearby Airports
Flying into Oakland instead of San Francisco, or Fort Lauderdale instead of Miami, can save hundreds. Factor in ground transportation costs before deciding.
10. Be Flexible With Destinations
Use the “Explore” feature on Google Flights or Skyscanner’s “Everywhere” search to find the cheapest destinations from your home airport for your travel dates.
MONEY-SAVING BOOKING TRICKS
11. Set Fare Alerts Early
Create alerts on Google Flights, Hopper, and Skyscanner months before your trip. Hopper’s price prediction tells you whether to buy now or wait.
12. Consider Budget Airlines (Carefully)
Carriers like Southwest, Spirit, and Frontier offer rock-bottom base fares. Just add up baggage, seat selection, and other fees before comparing with full-service airlines.
13. Use Airline Miles and Credit Card Points
A travel rewards credit card with a strong signup bonus can cover an entire international flight. Transfer points to airline partners for the best redemption values.
14. Book Directly With the Airline
Third-party sites occasionally undercut airlines, but booking direct gives you better customer service, easier changes, and full frequent-flyer credit when things go wrong.
15. Check for Error Fares and Mistake Prices
Follow deal sites that flag mistake fares, which can offer business-class seats at economy prices. Book immediately when you spot one, as airlines may or may not honor them.
16. Fly With Stopovers Instead of Nonstops
One-stop itineraries are often significantly cheaper than nonstops. Some airlines even let you add a free multi-day stopover in their hub city, giving you two destinations for the price of one.
17. Clear Your Cookies and Compare on Mobile
Some travelers report different prices on mobile apps versus desktop sites. It takes two minutes to check both, and the savings can be real.
WHAT NOT TO DO WHEN BOOKING FLIGHTS
- Don’t book on Friday or Sunday afternoons, when leisure demand peaks.
- Don’t assume the first price you see is the best; fares fluctuate daily.
- Don’t skip travel insurance on expensive international itineraries.
- Don’t book basic economy if you might need to change your plans; the restrictions are brutal.
FREQUENTLY ASKED QUESTIONS
What is the cheapest day of the week to fly?
Tuesday and Wednesday are typically the cheapest days to fly domestically in the US, with Saturday close behind. Friday and Sunday are usually the most expensive.

Fare differences by booking day are small, but Sunday bookings have shown slightly lower average prices in recent studies. What matters far more is which day you fly.

Airlines deny personalizing prices based on search history, but searching in private mode eliminates any chance of cookie-based price increases and is a smart habit.
