How to Find Cheap Flights: 15 Proven Tips to Save Money on Your Next Trip

Flights are often the biggest expense when planning a trip. Whether you’re dreaming of a weekend in Europe or a once-in-a-lifetime safari, finding affordable flights can make the difference between booking your trip or putting it off for another year.

The good news? You don’t need to be a travel expert to find great flight deals.

Over the years, I’ve learned that finding cheap flights isn’t about luck, it’s about knowing where to look, when to book, and being flexible when you can.

In this guide, I’ll share 15 practical tips that can help you save money on flights, without spending hours searching every airline website.

1. Be Flexible With Your Travel Dates

If your schedule allows, this is one of the easiest ways to save money.

Flying on a Tuesday or Wednesday is often cheaper than travelling on a Friday or Sunday, when demand is higher.

Even shifting your trip by a day or two can sometimes save hundreds of euros.

When searching for flights, always compare prices across an entire week instead of searching for one specific date.

2. Compare Flights Using Search Engines

Don’t book the first flight you find.

Instead, compare prices using multiple flight search websites.

Each platform may display different prices, airlines or routes.

Comparing several options takes only a few minutes and can lead to significant savings.

3. Book at the Right Time

One of the biggest myths is that there’s a single “best day” to book flights.

The reality is that prices constantly change based on demand.

As a general rule:

• Domestic flights: around 1–3 months before departure.
• International flights: around 2–6 months in advance.

Waiting until the last minute usually results in higher prices.

4. Set Price Alerts

Don’t have to book immediately?

Set a price alert.

Many flight comparison websites allow you to receive an email whenever the price changes.

This lets you monitor fares without checking every day.

5. Consider Nearby Airports

Most travellers automatically search from their nearest airport.

But driving an extra hour or taking a train to another airport can sometimes reduce the cost dramatically.

Likewise, flying into a nearby city instead of your exact destination may open up much cheaper options.

Always compare.

6. Travel With Hand Luggage Only

Budget airlines often advertise very low fares but charge extra for checked baggage.

Travelling with only a carry-on bag can save money while also making your journey quicker and easier.

You’ll skip baggage claim and reduce the risk of lost luggage.

7. Be Flexible With Your Destination

Sometimes the cheapest destination is one you hadn’t even considered.

Instead of searching for one specific city, browse destinations based on price.

You might discover somewhere incredible for half the cost of your original plan.

Some of my favourite trips started simply because they had unusually cheap flights.

8. Fly Outside Peak Season

Summer holidays, Christmas and school breaks are typically the most expensive times to travel.

Instead, consider travelling during the shoulder seasons.

For Europe, this usually means:

• April–May
• September–October

You’ll often enjoy:

• Lower prices
• Fewer crowds
• Better weather than expected

9. Book Flights Before Accommodation

Many people choose hotels first.

I usually do the opposite.

If flights are expensive for your chosen dates, adjusting your travel dates before booking accommodation can save a significant amount of money.

10. Don’t Ignore Budget Airlines

Budget airlines have opened up countless affordable travel opportunities across Europe.

While they often charge extra for optional services, they can still offer fantastic value.

Just remember to factor in:

• Baggage fees
• Seat selection
• Airport transfers

A cheap ticket isn’t always the cheapest overall option.

11. Travel Midweek

Weekend flights are popular for obvious reasons.

If possible, depart on Tuesday or Wednesday and return midweek.

These flights are often less expensive because fewer people are travelling.

12. Clear Your Browser? Probably Not Necessary

You may have heard that airlines increase prices based on your browsing history.

While this idea has circulated for years, there’s little evidence that clearing cookies consistently results in lower fares.

Instead of worrying about browser history, focus on comparing prices and booking when you find a fare you’re happy with.

13. Check the Total Cost

A €30 flight can quickly become a €120 flight once baggage, seat selection and other fees are added.

Always compare the final price before booking.

Sometimes a slightly more expensive ticket includes luggage and ends up being the better deal.

14. Sign Up for Airline Newsletters

Many airlines occasionally offer flash sales or promotional fares.

Joining their newsletters means you’ll hear about these deals before they disappear.

Just be prepared for a few extra emails in your inbox.

15. Book When You’re Happy With the Price

Many travellers keep waiting, hoping the fare will drop even further.

Sometimes it does.

Often, it doesn’t.

If you’ve compared prices, found a fare that fits your budget and you’re happy with it, book it.

The perfect deal doesn’t exist.

The goal is finding good value—not chasing the absolute lowest possible price.

Common Mistakes When Booking Flights

Avoid these common mistakes:

• Waiting too long to book.
• Booking without comparing prices.
• Ignoring baggage fees.
• Forgetting airport transfer costs.
• Choosing inconvenient flight times without considering the impact on your trip.

My Personal Approach

Whenever I plan a trip, I don’t spend weeks obsessing over finding the absolute cheapest flight.

Instead, I compare prices across several websites, stay flexible where possible and book when I find a fare that feels fair.

The time I save can be spent planning the exciting parts of the trip instead.

After all, saving €20 isn’t worth spending ten extra hours searching.

Final Thoughts

Finding cheap flights isn’t about knowing secret tricks.

It’s about understanding how airlines price their tickets and giving yourself enough flexibility to take advantage of better deals.

With a little planning, you can often save enough on your flights to pay for an extra night in a hotel, a memorable activity or a fantastic meal during your trip.

Travel doesn’t always have to be expensive.

Sometimes, it simply starts with booking smarter.
