Looking for cheap international flights? I'll show you my personal 3 step process to finding the best flight deal 95% of the time - and all in just 20 minutes or less!
Why You Should Listen to Me: I've been traveling internationally nearly non-stop for almost three years, covering 44 countries and 6 continents along the way. I've taken a ton of flights - and rarely paid more than a couple hundred dollars for them.
I've spent countless hours searching for cheap international flights on virtually every search engine available. And I can tell you definitively that most of them promise way better results than they can actually deliver.
So to save you time and money I put together this ultimate guide to finding cheap international flights. I'll go over my #1 rule for finding cheap flights and walk you through the exact 3-step strategy I personally use nearly every week to find my own flights. And, no, this doesn't require any miles or points (that's a subject for another post).
Full disclosure: These are the sites I personally use to find my own flights. I am not affiliated with Google Flights or ITA Matrix, but I am an affiliate of Jetto and may receive a commission from them for referrals.
Don't have time to read the full detailed guide to finding cheap international flights?
That's ok. Here's the tldr;
Be flexible in your searches, and then follow these three steps:
That's it in a nutshell, but read on for a full walk-through of how to implement this strategy (or bookmark this page for later, or click here to pin it on Pinterest).
Before I walk-through my three-step process for saving money on flights, I want to explain the number one rule that underlies my process.
This requires a bit of a digression, so if you just want click here to skip to my 3-step process for finding cheap international flights.
But I really think that taking the time to truly understand this rule can totally change the way you think about finding cheap flights.
So what is my number one rule for saving money on flights?
Be flexible about the three “Ds.”
What are the three “Ds”?
The more of these three you can be flexible about, the more you will save.
Well, it really comes down to a matter of math.
The more possible flights you can price out, the more likely it is you will find that gem of a deal.
That said, it’s ok if you have to be firm about one or even two of them.
But if you’re committed to flying from a particular airport to another particular airport on a set day … well, that’s where the airlines make their money.
Don’t believe in the power of the three Ds yet?
Let’s go through three quick examples to show how maximizing your flexibility with the three Ds can open you up to nearly 5,000 times as many options for potential flights (remember: more potential flights = more potential bargains!).
First, we need to make one assumption: let’s assume for argument’s sake that on average there are 10 flights a day between any two given destinations (I know that’s not true literally, and it will vary quite a bit by airport pair in real life, but we need to make this assumption or else the following illustration gets way too difficult to convey).
Ok, on to the examples …
Now let’s start with a simple example: imagine you are trying to go from Philadelphia to Paris on a specific Friday.
1 departing airport x 1 destination x 1 date x 10 flights/pair = 10 flights
1 departing airport
10 possible flights
In our hypothetical, that would mean you only have 10 flight options.
That’s it. If the cheapest of those is $2,500 … well, you’re going to have to pay $2,500.
But let’s say instead that you’re a little bit flexible about dates. You’re willing to leave and return on either Thursday, Friday, or Saturday.
And you’re open to taking the train to nearby Newark or Baltimore’s BWI if it means a cheaper fare.
And you’re open to going to Amsterdam or Brussels instead (both of which are a train ride away from Paris).
Now let’s see what happens to your options:
3 dates x 3 departing airports x 3 destinations x 10 flights per destination pair =
3 departing airports
90 possible flights
By just adding a little flexibility to your search, you’ve now got nearly 10 times the flights to choose from. And I can tell you from experience that means you are MUCH more likely to find a dirt-cheap flight.
But I bet you can do even better than that, so let’s check out our next example …
Ok, let’s say instead that you are willing to fly any day that week, are happy to go as far as Boston, New York’s LGA and JFK airports, or DC’s National and IAD airports. And you just want to travel somewhere really cool in western Europe, but are open not just to Paris, Amsterdam, and Brussels, but also to instead heading to Rome, Madrid, Barcelona, London, or Dublin.
Now let’s see how many flight options will be competing for your purchase:
8 departing airports
4,480 possible flights
Yes, really: that's 4,480 flight options you can compare now!
By adding this degree of flexibility to your plans, you increase your chance of finding that bargain airfare by almost 500 times!
In fact, it doesn't have to stop there. If you were flexible about leaving any day of the month, and open to flying to 20 possible destinations across Europe, under our scenario above that would result in 49,600 flight options - and, no, that's not a typo!
Ok, you get the point: flexibility means you have way more options. And competition equals savings.
Now, this is usually the point in the conversation where most people say something like:
“Nate, that sounds like a LOT of work. And I have a full-time job and a life, unlike you dude. How the heck am I going to run all those searches for all those possibilities?”
Never worry, my friend, it’s MUCH easier than you think.
Just follow my simple 3 step process to finding cheap international flights:
If you tried to run 4,480 searches for each of the potential combinations in Example 3, you’re probably end up going mad from frustration and boredom.
Thankfully, you don’t have to! In fact, you could do most of it with as few as just 8 quick searches!
There’s a lot of opinions about what is the best search engine for finding cheap international flights.
But after buying hundreds of flights all around the world, I’ve found that most flight search engines are ... pretty much the same.
Except for two.
The first of those is Google Flights.
Google flights is great because it allows you to combine the power of a flexible calendar search with a handy “explore” feature that lets you easily search nearly every airport in the world and up to six months of dates at a time.
The tool is really easy to use once you know how, but it’s a little hard to explain my process in text, so I made this quick video to walk you through how to do it:
Isn’t that incredible?
One note: the only one of our three Ds that you can’t easily search in one sitting is your departing airport. So, in our Example 3 above, you’d need to run this search process on Google Flights 8 times to cover all your bases.
Know why most airfare search tools give basically the same results?
Because the dirty secret is that many of them pull their data from the same sources.
And what Kayak and Momondo and Expedia don’t want you to know is that you can search one of the main sources - the ITA Matrix - yourself! You don’t need their money-grubbing middleman paws in your way.
Here’s another quick video I made walking through how to use the ITA Matrix to search for cheap flights:
Fair warning: though it’s more powerful, it’s not nearly as intuitive a tool to use as Google Flights (which actually now owns the ITA Matrix).
If you prioritize your time, you can probably skip using the ITA Matrix and just use Google Flights. I’d bet that 90% of the time you’ll still get the best deal just with step one.
Ok, so step #1 and step #2 can save you boatloads on cheap international flights.
But wouldn't it be nice if there was a robot that would do the work for you every single day?
