How to Find the Cheapest Flights in 2025: Tools, Tips, and Tricks
Finding cheap flights can feel impossible these days, but it’s not. In 2025, smart travelers use data, flexible dates, and powerful comparison tools to score serious deals on airfare.
Whether you’re flying to Europe, the Middle East, or a quick city escape, this guide will show you how to find the cheapest flights — every single time.
1. Use Flight Comparison Tools Instead of Booking Directly
If you’re still jumping from airline to airline searching for deals, you’re wasting time. Use flight comparison sites that pull data from hundreds of airlines instantly.
Best tools to use:
Skyscanner – perfect for flexible travelers who can adjust dates or airports to get the best prices.
Aviasales – great for finding hidden low-cost carriers and flash deals.
💡 Pro tip: Always switch to “whole month” or “cheapest month” mode — it instantly shows when fares drop the most.
2. Be Flexible with Your Dates and Airports
Flight pricing changes daily, and flexibility is your secret weapon.
Try this:
Shift your departure or return by a day or two.
Fly mid-week (Tuesdays and Wednesdays are cheapest).
Use nearby airports — for example, flying into Brussels instead of Paris or Milan instead of Zurich can save you £100+.
Skyscanner’s “Everywhere” feature is ideal if you’re open to new destinations based on price.
3. Set Fare Alerts to Catch Price Drops
Prices can change multiple times per day. That’s why fare alerts are essential.
Set up alerts on Aviasales or Skyscanner to:
Get notified when your chosen route’s price drops.
Compare past fare trends.
Book the moment prices fall below average.
💡 Tip: Track multiple destinations at once — sometimes Rome drops before Paris, or Athens before Madrid.
4. Clear Cookies or Use Private Browsing
Flight sites use cookies to remember your searches. The more you check a route, the higher prices can appear.
To beat this:
Use Incognito mode (Ctrl + Shift + N in Chrome).
Or search on your phone after checking on desktop.
This small step can instantly reduce fares by 5–15%.
5. Mix Airlines and One-Way Tickets
A single airline rarely offers the cheapest round-trip. Using comparison sites, you can mix and match airlines easily.
For example:
Fly out with Ryanair and back with Wizz Air.
Or arrive in Paris and depart from Rome on a different carrier.
Skyscanner automatically combines airlines and airports to find the most cost-effective itineraries.
6. Book at the Right Time
Booking too early or too late can cost you. Based on flight data from 2025:
Best time for international flights: 6–10 weeks before departure.
Best time for domestic flights: 3–6 weeks before departure.
Best booking days: Tuesday and Wednesday.
Track prices for a week before you buy — patterns emerge fast.
7. Join Airline Newsletters and Reward Programs
Airlines often drop exclusive discounts via newsletters or loyalty programs before public release.
Join these now:
Major airlines like Emirates, Qatar, Turkish, and EasyJet.
Price trackers like Aviasales.
Hotel and travel rewards programs to stack points across bookings.
Combine this with a travel credit card for extra cashback or free upgrades.
8. Don’t Forget Hidden Costs
A cheap ticket isn’t really cheap if it adds £80 in luggage or seat fees. Always:
Compare total prices (including extras).
Check refund flexibility and carry-on limits.
Use comparison filters like “no hidden fees” on Aviasales.
Transparency builds trust — for both your readers and affiliate partners.
Final Thoughts
Finding the cheapest flights in 2025 isn’t luck — it’s strategy.
If you compare using Skyscanner, set alerts, clear cookies, and stay flexible, you’ll always find the best deals.
