Top Websites to Book Cheap Flights to Anywhere in the World

Top Websites to Book Cheap Flights to Anywhere in the World

Want to know where you can easily book cheap flights? 

Many of us have tried using different strategies for budget airfares. But, in reality, prices depend on demand, not on the day or time you try to book a flight.  

The only problem now is, with so many options, will you need a dozen tabs open to find the best ticket prices? 

Unfortunately, this is certainly a possibility. There is no single website that consistently offers the lowest prices. 

Luckily, you don’t have to suffer that time-consuming process anymore. We’ve done all the dirty work for you! 

In this article, we’ll explore some of the top booking websites you can trust to book cheap flights to anywhere in the world. 

The best sites to book cheap flights under $100

The web is brimming with different flight search engines. Aside from booking directly with one of the top airlines, the following sites will help you uncover the cheapest airfare prices.

1. Google Flights

Google Flights is just like any other flight search engine. You enter your travel dates, the number of passengers, and the class of service you desire. Once you click search, you’re given a multitude of options from different airlines initially sorted by the best flights available. It then shows the duration of the flight, number of stopovers, and available airlines.

If you don’t have any desired target date or location, Google Flights is a great option. 

For starters, they have an ‘explore destination’ feature. This guides you to the cheapest airfares around the next six months from your starting point to other popular destinations. 

It also has the following features:

Flexible calendar:

This feature allows you to find the cheapest flights up to 11 months in advance. It does this by automatically adjusting the travel dates depending on your desired duration. 

Price alert

This feature is best suited for individuals who are in no rush to travel. Google will send alerts to your Gmail when the prices of tickets increase or decrease. 

Travel guide

This feature takes away all the stress of planning a vacation. Google provides the top places to visit when traveling to a certain location. It even provides the expected climate in a given month, available activities, and the average prices for hotels.

Greener flights

For every search made, Google highlights flights with airplanes with lower carbon emissions.  


  • Doesn’t display prices of all online travel agencies (OTAs)
  • On rare occasions, it can show ghost flight schedules 

2. Expedia

Expedia is an online travel agent that helps you book and plan a worry-free vacation. Like Google Flights, Expedia has a flexible calendar to see if cheaper flights are available on certain dates. 

It also has the following features:

There are two easy options when rebooking or canceling your flight on Expedia. You can either call their hotline or log in to your Expedia account and click on the itinerary page.

Like Google Flights, this feature helps you filter for airplanes with lower carbon dioxide emissions for a more eco-friendly trip.

It also has the following features:

Kayak now offers a free ‘business mode’ feature for companies with frequent fliers. Once you submit a search, you can view your company’s policies to get flights approved at the touch of a button. It also allows you to avail of hotel corporate rates, and see which hotels have been recommended by your coworkers.


Available with every business membership, Kayak’s virtual assistant allows you to do even more: build itineraries, do online check-in, and share your trip with friends and family.

This Kayak feature will keep you up-to-speed on any cancellations, delays, or gate changes on your flight.

Travel restrictions
