How to Find Cheap International Flights (Without Getting Lucky)

It’s not a fluke — it’s a strategy.

In the last five years, I’ve flown from the U.S. to Europe for under $500 roundtrip, booked a $130 flight to Belize, and saved hundreds of dollars using a few repeatable tricks. And no, I’m not some elite travel hacker with endless points and secret codes. I’ve just learned how to find cheap flights anywhere in the world — and you can too.

Here are my favorite ways to do it, from airfare alerts to travel card hacks to creative routing. Whether you’re planning your first international trip or trying to save on your next one, this guide gives you five solid ways to get started.

1. Use Flight Deal Tools That Actually Work

Most travelers know about Google Flights or Kayak. But if you’re only searching in real time, you’re missing the best deals. Instead, let the deals come to you.

Here are a few tools I swear by:

Thrifty Traveler: Find cheap flights without doing the work with them sending you the best deals when they find them. I took a trip to Ireland on a $130 roundtrip flight (seriously).
Hopper: Predicts future airfare prices and tells you when to book. It’s great for travelers who have a destination in mind but want to wait for the best time to buy.
Google Flights “Explore” tool: Use this when you don’t care where you go — just that it’s cheap. You can type in your departure city, select “Europe” or “South America,” and see a map of the lowest fares across the continent.

If you’re flexible, these tools alone can unlock fares that feel “too good to be true” — but aren’t.

2. Fly Into (or Out Of) a Major Hub

You don’t have to live in a major city to take advantage of cheap flights — but you might need a positioning flight.

Many of the cheapest international deals leave from big U.S. airport hubs like New York, Chicago, or Miami. So if you’re flying out of a smaller regional airport, it can actually be cheaper to book two separate tickets:

One from your home airport to the hub (domestic flight)
One from the hub to your international destination

My husband and I did this when flying to Thailand. Flights from Louisville were over $1,400 per person — but flying from New York was only $600. We booked a budget flight to NYC the day before, spent the night, and saved over $1,600 total.

3. Travel in Shoulder Season

If you’re trying to fly in July or over the winter holidays, I’m sorry to say: it’s probably going to be expensive. But shoulder season? That’s where the magic happens.

Shoulder season = the sweet spot between high and low season.
You’ll often find:

Cheaper international flights
Better hotel rates
Fewer crowds and milder weather

The exact timing depends on the region, but for Europe, it’s usually April–May and September–October. Southeast Asia? Think May or November, depending on the country.

I try to plan 80% of my international trips during shoulder season — it’s cheaper, calmer, and still beautiful.

4. Use Travel Rewards to Cover Flights

Some of the best “cheap” flights I’ve taken cost $0 — thanks to points and miles.

Even if you’re not deep into travel hacking, getting just one good travel credit card can unlock international flights for free. For beginners, I always recommend the Chase Sapphire Preferred, which often comes with a big welcome bonus (enough for a roundtrip flight to Europe or South America).

You can use points to:

Book directly through your card’s travel portal (easy)
Transfer to airline partners like United, Air France, or Aer Lingus for better redemptions (advanced, but worth it)

Don’t want another credit card? You can also earn airline miles by:

Flying and crediting to a frequent flyer account
Using shopping portals that earn you miles for online purchases

5. Be Flexible With Dates (Or Destinations)

This is probably the single most important strategy for saving on international flights.

Most people search like this:

Choose their exact travel dates
Choose their destination
Hope for a decent price

But that’s the most expensive way to book.

Instead, try reversing the process:

Look at the cheapest dates to fly
Explore what destinations are cheapest then
Book your trip around the best combination

Start with Google Flights or Skyscanner’s flexible search tools. Search entire months, not just weekends. If you’re set on a place like Italy, be open to flying into Rome, Milan, or even another European city and connecting with a budget carrier.

A little flexibility can literally save you hundreds of dollars — no fancy hacks required.

Final Thoughts: You Don’t Have to Overpay to See the World

I’ve flown roundtrip to Europe for less than $300. I’ve booked flights to Belize for under $150. These aren’t flukes — they’re the result of smart tools, a bit of planning, and a mindset shift around what “normal” airfare costs.

Use these strategies in combination and you’ll start to see what’s possible.
No more $1,300 tickets. No more giving up on international travel because the prices feel too high.

Just smarter flying, cheaper trips, and more money left to spend while you’re there.
