1. Understand the Myth vs. Reality
There’s a lot of outdated advice floating around the internet, such as "Always book on a Tuesday at 1 p.m." While this may have worked in the past, 2025’s airline algorithms are far more sophisticated.
What really matters today:
Booking window: How far in advance you book.
Travel days: Which day of the week you plan to fly.
Destination trends: Popularity of your destination during your chosen dates.
Time of day: Surprisingly, this still plays a role.
So, instead of relying on outdated myths, focus on what actually influences flight prices in real-time.
2. Best Days of the Week to Book Flights
According to updated 2025 studies from travel platforms like copyright and Hopper:
✅ Tuesday and Wednesday: Still the Best Bets
While not a hard rule, airlines often release fare discounts on Monday evenings. By Tuesday or Wednesday, competing airlines have matched or undercut those prices.
❌ Fridays and Sundays: Avoid If You Can
Booking on weekends, especially Sunday evenings, often results in higher fares. These are high-demand booking days when business and leisure travelers are finalizing plans.
Pro Tip: Set fare alerts on Tuesday and monitor for a 24–48 hour window to catch a potential drop.
3. Know the Optimal Booking Windows
Booking too early or too late can cost you. Here's the sweet spot based on destination type:
✈️ Domestic Flights:
Best time to book: 1 to 3 months before departure.
Avoid booking more than 5–6 months out unless it’s peak season.
???? International Flights:
Best time to book: 2 to 6 months in advance.
For peak seasons (holidays, summer), aim for 6–9 months ahead.
????️ Holiday Travel:
Book at least 3–6 months early. These fill up fast and surge in price.
4. Use Flexible Date Search Tools
When it comes to finding the cheapest days to book, flexibility is key. The more open you are with travel dates, the better the deal you can score.
Here are the best tools to help:
???? Google Flights
Flexible date grid shows prices for an entire month.
Suggests cheaper nearby airports and alternative dates.
Tracks fare drops with alerts.
???? Hopper

Tells you whether to “Buy Now” or “Wait.”
Includes “Freeze Price” option.
???? Skyscanner
“Cheapest Month” feature shows the best time to travel.
Global search allows you to find the best flight anywhere.
???? Kayak
“Price Forecast” indicates whether you should book now or wait.
“Explore” lets you search destinations based on your budget and time.
5. Leverage Fare Alerts and Track Prices
If you're not ready to book yet, don't worry—just set up fare alerts. Most top platforms let you track specific routes and dates.
How to use fare alerts effectively:
Choose 2–3 platforms (e.g., Google Flights, Skyscanner, Hopper).
Set alerts for your desired route and flexible dates.
Monitor changes daily or weekly.
Book immediately when the price dips below average.
6. Fly on the Cheapest Days
Not only should you book on the right day, but also try to fly on the most affordable days of the week.
Cheapest Days to Fly (Generally):
Tuesday
Wednesday
Saturday (evening)
Most Expensive Days:
Friday
Sunday
Flying mid-week is typically less popular for business and leisure travelers, which leads to lower prices.
7. Travel During the Off-Season
Avoid peak season to get the lowest fares. Each destination has its own off-season, but in general:
???? Low Travel Months Include:
January – Early March: After the holiday rush.
Late April – Early June: Before summer vacations.
Mid-September – Early November: After summer ends.
Booking during these months and flying mid-week gives you the highest chance of landing a deal.
8. Combine One-Way Tickets for Flexibility
Sometimes booking two one-way flights on different airlines can save more than a round-trip ticket. Use tools like Kiwi.com or Momondo to mix and match flights.
Bonus: You gain more flexibility with departure and return times and can explore different airport options.
9. Avoid Dynamic Price Increases
Believe it or not, airline websites and booking platforms may raise prices based on your browsing behavior.
Here’s how to avoid that:
Use Incognito/Private Mode when searching.
Clear browser cookies between sessions.
Use different devices/IPs if prices start rising strangely.
This may not guarantee lower fares, but it can prevent unnecessary increases during your search.
10. Book Early for Budget Airlines
If you’re flying with low-cost carriers like Ryanair, EasyJet, or Spirit, early booking is essential. These airlines reward early birds and often charge more as departure dates approach.
Tip: Sign up for email notifications from budget airlines—some offer exclusive early access to promotions.
