The Best Flight Search Engines to Buy Cheap Plane Tickets

The 7 Best Websites to Find Cheap Flights

One of the best tricks to save money on a trip is to find cheap flights. This doesn’t mean the quality of your experience will be lower—on the contrary, you’ll enjoy the same but pay less. You just need to know where to look.

With that in mind, here are 7 of the best websites to find cheap plane tickets:

1. Google Flights

We start the list with a product developed by Google, known for its intuitive interface that effectively compares prices. In addition to finding cheap flights, Google Flights provides detailed information on schedules and available airlines.

Simply enter the website and fill in your travel details to instantly receive a list of multiple options. It also allows you to track prices and receive alerts to identify the most affordable days to travel.

Another advantage is its integration with other Google services, including Google Travel for trip planning.

2. Skyscanner

This search engine is popular for several reasons. One of them is that it compares prices for flights, hotels, and car rentals across more than 1,000 airlines and online travel agencies.

It also features the “Anywhere” function, appreciated by travelers who are flexible with their destination, as it suggests the cheapest places for their next adventure. Additionally, it offers filters to personalize searches based on preferences, including eco-friendly flights.

It’s important to note that while Skyscanner allows you to view flights, hotels, and more, you must complete your booking on the airline or travel agency’s website since it does not sell tickets directly.

3. Expedia

If you prefer an option with comprehensive coverage in one place, opt for a well-known agency like Expedia. This company offers a wide range of services for planning and booking trips.

In addition to buying cheap plane tickets, you can manage hotel reservations, transportation, and even vacation packages—all in one place.

One of its highlights is the rewards program that allows you to earn points and get future discounts. Unlike Skyscanner or Google Flights, Expedia allows you to complete purchases directly on its platform, providing a more integrated booking experience.

4. Last Minute

This option stands out for offering competitive deals on multiple travel services, from flight and hotel reservations to cruises, vacation packages, and city getaways.

Last Minute is also known for its focus on last-minute deals for travelers looking for cheap flights. Its user-friendly interface and customizable options make it an excellent alternative.

Want discounted fares to various destinations? Go to the "Outlet Flights" section and find exclusive deals on plane tickets.

Last-minute discounts can reach up to 30% or more.

5. Momondo

Momondo searches and compares prices across more than 700 platforms worldwide and has expanded to over 35 international markets. Like the previous options, it updates prices in real-time and helps you find cheap plane tickets.

Its system displays the cheapest options, along with the availability of flights, hotels, and other travel services. It also lets you create itineraries, filter results, and set price alerts.

However, it does not sell tickets or reservations directly—it only provides an overview of available options. To complete the purchase, it redirects you to the respective providers.

6. Kayak

Another intuitive flight search engine is Kayak, a comprehensive site that also offers accommodation, transportation, and vacation packages.

It compares prices across multiple travel sites in real-time and presents a selection of promotions all in one place. Additionally, its price prediction tool analyzes trends and advises whether to book immediately or wait for a possible price drop.

To increase your chances of finding cheap flights on Kayak, adjust your search filters based on your budget and preferences.

7. Rumbo

Rumbo's platform also tracks the best deals across more than 400 airlines to find cheap flights. Like several other services mentioned, it includes hotel reservations, lodging, and transportation options.

What makes it particularly attractive are its vacation packages with various experiences, along with its "Flash Sales" promotions—limited-time offers with exclusive prices on flight + hotel packages.

It also offers loyalty programs with perks like gifts, discounts, and personalized coupons. This makes it a practical alternative for securing competitive deals and managing all aspects of your trip.

Pros and Cons of Using Flight Aggregators

If you want to save money, flight aggregators are the perfect tools to find and buy cheap plane tickets. They gather information from a variety of airlines and travel agencies, making comparisons easy.

Here are some pros and cons:

Despite the downsides, companies and agencies like Kayak, Last Minute, Despegar or Expedia save you both time and money. They are undoubtedly valuable tools for getting information tailored to your needs and budget.

Finally, we recommend trying DolarApp to book and pay for your trips to international destinations. With DolarApp, you can avoid high bank fees by requesting your Mastercard DolarCard, which allows you to pay directly in USDc.

DolarCard lets you make purchases with digital dollars at physical stores and online, making it a practical solution for buying cheap plane tickets and covering travel expenses.
