Finding cheap flights can be a frustrating experience. You search on one website only to find the exact same flight hundreds of dollars cheaper on another site.

If you’re short on time, here’s a quick answer to your question: Google Flights often displays cheaper fares because it pulls price data from multiple sources, including airline sites and online travel agencies.

In this comprehensive guide, we’ll compare Google Flights to other flight search engines and explain why it frequently shows lower prices. We’ll also provide tips to save money no matter which site you use.

How Google Flights Sources Prices

Google Flights is able to offer competitive prices due to its innovative approach to sourcing flight prices.

By combining data from various sources, Google Flights is able to provide users with the best possible fares.

Here’s a detailed look at how Google Flights sources its prices:

Direct Connections to Airlines

One way Google Flights obtains prices is through direct connections to airlines.

This means that Google has established partnerships with airlines, allowing them to access real-time pricing information.

By having this direct connection, Google Flights can offer users accurate and up-to-date prices, ensuring that they are getting the best deal available.

Partnerships with OTA Sites

In addition to direct connections with airlines, Google Flights also partners with Online Travel Agency (OTA) sites.

These partnerships enable Google to access prices from a wide range of travel booking platforms.

By aggregating data from multiple sources, Google Flights can offer users a comprehensive view of available flights and prices.

When users search for flights on Google Flights, they are presented with options from various OTA sites, allowing them to compare prices and choose the best deal.

This partnership model allows Google to provide users with a seamless booking experience and ensures that users have access to the most competitive prices in the market.

Use of Predictive Algorithms

Google Flights employs advanced predictive algorithms to analyze historical flight data and predict future prices.

These algorithms take into account factors such as seasonality, demand patterns, and other market trends to estimate the likelihood of price fluctuations.

By using these algorithms, Google Flights can help users make informed decisions about when to book their flights.

Furthermore, Google Flights also provides users with price tracking features that allow them to monitor fare changes and receive notifications when prices drop.

This helps users take advantage of lower fares and save money on their flights.

Factors that Influence Flight Prices

When it comes to booking flights, it’s no secret that prices can vary greatly.

While Google Flights may offer cheaper options, there are several factors that influence flight prices across all flight search engines.

Understanding these factors can help you make more informed decisions when planning your next trip.

Airline Ticket Types and Classes

One of the key factors that can influence flight prices is the type and class of ticket you choose.

Different airlines offer various ticket types, such as economy, premium economy, business class, and first class.

Each ticket type comes with its own set of amenities and services, and naturally, the prices vary accordingly.

For example, first class tickets are typically more expensive than economy class tickets due to the additional comfort and luxury offered.

Pro Tip: If you’re looking to save money, consider opting for economy or premium economy tickets instead of business or first class.

While you may not have the same level of luxury, you can still enjoy a comfortable journey at a more affordable price.

Demand-Based Pricing

Flight prices are also influenced by demand-based pricing, which means that prices fluctuate based on the level of demand for a particular flight.

During peak travel seasons or holidays, flight prices tend to be higher due to increased demand.

On the other hand, during off-peak seasons or less popular travel times, prices may be lower to attract more travelers.

Pro Tip: If you have flexibility in your travel dates, consider booking your flights during off-peak seasons or midweek when prices are generally lower.

This can help you save a significant amount of money on your airfare.

Dates and Times of Travel

The specific dates and times of your travel can also impact flight prices. In general, flights booked well in advance tend to be cheaper than last-minute bookings.

Additionally, flying during non-peak hours or on weekdays can often result in lower prices compared to flying during peak hours or on weekends.

Pro Tip: To find the best deals, try to be flexible with your travel dates and times.

Use the search filters provided by flight search engines, including Google Flights, to explore different options and compare prices across various dates and times.

Comparing Google Flights to Other Sites


Kayak is a popular flight search engine that allows users to compare prices from various airlines and online travel agencies.

While Kayak offers a wide range of options and filters to help users find the best deals, it may not always have the most up-to-date prices.

Google Flights, on the other hand, uses real-time data from airlines and travel agencies to provide users with the most accurate and current prices.

This can often result in lower fares on Google Flights compared to Kayak.


Expedia is another well-known flight search engine that offers a comprehensive platform for booking flights, hotels, and car rentals.

While Expedia may have a larger inventory of flights and travel options, Google Flights focuses on providing users with the most relevant and cost-effective options.

In addition, Google Flights often includes hidden fees and charges in its search results, ensuring that users have a clear understanding of the total cost of their flight.


Priceline is known for its “Name Your Own Price” feature, which allows users to bid on flights, hotels, and rental cars.

While this can be a great way to save money, it can also be time-consuming and may not always guarantee the best deal.

Google Flights, on the other hand, provides users with a simple and straightforward search interface that quickly displays the best available options.

This can save users time and effort while still offering competitive prices.

Airline Sites

Many travelers choose to book directly through airline websites in the hope of finding the best deals. While this can sometimes be the case, it often requires visiting multiple websites and comparing prices manually.

Google Flights aggregates data from multiple airlines and travel agencies, allowing users to compare prices and find the best deals all in one place.

This convenience, coupled with Google Flights’ ability to provide accurate and up-to-date information, makes it a popular choice for travelers looking for the cheapest flights.

When comparing Google Flights to other flight search engines, it is clear that Google Flights stands out for its accuracy, convenience, and competitive pricing.

By utilizing real-time data and providing users with a comprehensive search interface, Google Flights ensures that users can find the best deals without any hassle.

Tips for Finding the Lowest Fares

When it comes to finding the best deals on flights, there are a few strategies you can employ to ensure you get the lowest fares possible. Here are some tips to help you find the cheapest flights:

Be Flexible with Dates

One of the most effective ways to find cheaper flights is to be flexible with your travel dates.

Airlines often have different prices for different days of the week, so being open to adjusting your departure and arrival dates can save you a significant amount of money.

Consider flying on weekdays or during off-peak seasons when prices tend to be lower. Additionally, being flexible with your layovers can also help you find cheaper flights.

Check Prices Regularly

Flight prices can fluctuate greatly, so it’s important to check prices regularly and be patient.

Set up price alerts on flight search engines or sign up for newsletters from airlines to stay updated on any price drops or special promotions.

By monitoring prices over a period of time, you can identify trends and find the best time to book your flights.

Use Private/Incognito Browsing

Did you know that flight prices can sometimes increase based on your browsing history?

Flight search engines and websites use cookies to track your searches and may show higher prices if they detect that you’re repeatedly searching for the same flights.

To avoid this, use private or incognito browsing modes when searching for flights. This way, your search history and cookies are not saved, giving you a better chance of finding lower fares.

Clear Cookies and Cache

If you’ve been searching for flights on a regular browser window, it’s a good idea to clear your cookies and cache before booking. This will remove any stored data that might be influencing the prices displayed to you.

Clearing your cookies and cache ensures that you’re seeing the most up-to-date and unbiased flight prices.

Remember, finding the cheapest flights requires a bit of research and flexibility. By following these tips and staying vigilant, you’ll increase your chances of snagging great deals on your next trip.


In summary, Google Flights often displays lower fares because it compiles pricing data from many sources. However, prices can fluctuate frequently based on supply and demand.

By being flexible with your travel dates, checking back often, and using tools to hide your browsing history, you can increase your chances of finding a deal no matter which flight search engine you use.
