1. Google Flights

Google Flights is a very user-friendly flight search engine. It’s typically where I begin and end my search with Google Flights.

It offers customizable travel features to tailor your search to your travel preferences,

Select the ‘Explore‘ option at the top left tab of the page. Once you search, you will see all the flights your map view is hovered over.

From there you’ll see the cheapest flights within the selected timeframe.

Pros of Google Flights:

You are able to search by region, continent, or country
It includes additional fees in your search so you know you are booking what was shown in the original results
It will give you third-party sites to book on, giving you the best price

Cons of Google Flights:

Not all airlines show up in Google Flights search results

Google Flights search results using its explore feature to find the cheapest flights in a 6 month time frame.

2. Kayak

Kayak is a great website to have in your toolbox when searching for flights.

I use Kayak to compare flight prices I find on Google and Skyscanner.

It includes most airlines in its search, making it very easy to compare prices across several airlines.

You’ll select your home airport and set the destination to Anywhere.

From there, you will click the dates box and select a date range. You then will be able to select any time, a specific month, and the duration of your trip.

Pros of Kayak:

Includes price trends and location overviews in your search
Can track flights with price alerts

Cons of Kayak:

Doesn’t automatically include additional fees in your search
Doesn’t automatically use the flexible dates feature

Tip: Once you select your flight, you will see Kayak’s prediction on if they think it’s likely or unlikely that prices will down in the near future. This can help you decide if you should book right away or you can track the flight prices and have them sent straight to your email for a better deal.

3. Skyscanner

Skyscanner is another powerful tool that connects you to affordable flights using flexible travel features.

Skyscanner is also known for finding great prices on last-minute travel.

Select your home airport and set the destination to Everywhere. This flight search engine allows you to find cheap flights by date or by month.

Once you choose your location, you’ll be able to adjust your travel days based on one-way flights.

This could result in you flying different airlines each way but allows you to get the best deal.

Pros of Skyscanner:

You can select the month you travel by utilizing the cheapest month feature
Can track flights with price alerts
It will give you third-party sites to book on, giving you the best price

Cons of Skyscanner:

Doesn’t always reflect additional fees or displays inaccurate data
It will not display all airlines

This image shows the Skyscanner flight search engine using the everywhere feature that helps find insanely cheap flights. The search bar has a dropdown menu next to the "Depart" and "Return" date fields, indicating the flexibility in choosing your month of travel.

How the Flexible Travel Option Works

The flexible travel features on flight search engines allow you to see all flights happening within a specific timeframe that is flying out of your home airport.

So instead of trying to find cheap flights by date, you will choose your flight and location based on when it is a more affordable time to fly based on the search results.

Find Insanely Cheap Flights Around the Peak or Off-Season

When using the flexible search feature on flight search engines, if you don’t select specific dates, you’ll start to see the trends on when the best time to fly is.

A helpful feature in Google Flights is that it will outline the peak and off-season of a place when you are previewing a flight.

You’ll notice that flights are typically more affordable in the off or shoulder seasons. Shoulder seasons are the months in between the off and on the season for a particular place.

FAQ About Finding Insanely Cheap Flights

How Far in Advance Should you Start Searching for Flights?

The best time to book flights is between four to six months. For international flights, I usually start looking closer to six months out. I’d recommend utilizing Google Flight’s flight tracking feature to keep an eye on if flights drop in price instead of booking right away.

Where Should I Book My flight?

Once you select the flight you’d like to purchase you will be transferred to the airline’s website to book your online airline ticket.

Because I have a travel credit card, I also like to look in my Chase Sapphire Preferred travel portal to see if I can find the same flight.

Using Flight Search Engines on Desktop Vs. Mobile

Searching for flights on desktop vs. mobile comes down to personal preference. You will be able to access all the same features on mobile.

I like to search for flights on my desktop so I am able to have a full map view and quickly move between tabs to research different flights on the different flight search engines.

Wrapping Up

The flexible search features on flight search engines are truly game changers in your travel budget.

Especially when booking international flights, those prices can be intimidating if you are not utilizing travel points.
