This online flight search tool allows users to search for up to seven departure and destination airports at a single time, allowing users to find the best deal not only at their desired airports, but also at nearby airports.

  • Customizable search options allow users to generate multiple sample travel itineraries and receive email alerts when flight prices drop for their desired destination


  • This airline ticket search engine uses cookies to track when users search for the same destination multiple times and will raise ticket prices on repeat searches for the same destination unless being used in a private browser or Incognito Mode
  • As a metasearch engine, flights are not booked directly through Google, so users who need to change their itinerary or receive a refund must do so through the individual vendor
  • Google sometimes recommend OTA that does not serve or has minimum support for your country of residence. Be sure to check before finalizing your booking. With minimum support, a problem along the way can be complicated to solve.

The Difference Between Metasearch Engines and OTAs

It’s important for travelers to know the difference between a metasearch engine and an online travel agent, or OTA. While both of these search options offer users details and information on flights and travel, the main difference is that metasearch engines display a more comprehensive list of results, but can only be utilized for comparing prices, not booking actual flights.

When using a metasearch engine, users who have found the best flight or hotel deal for their budget can select the option via the search engine, but will then be directed to either the airline or company website or a third party travel booking site like an OTA to finalize their booking. Metasearch engines can be a valuable tool for users to find and compare the best prices as they search across multiple platforms, but online travel agents do all the leg work when it comes to actually booking a vacation.

A Word About Booking Directly Through the Airline

Although it may seem old fashioned to some, booking directly through the airline is still one of the best ways for travelers to take advantage of certain benefits like loyalty programs, special discounts, and more. In addition to saving money on travel, most major airlines provide a higher standard of customer services for clients booking flights directly through the airline versus through a third party booking site. Benefits of direct booking:

Airline Loyalty Programs

The goal of most major airlines is to make their customers happy. One way airlines strive to keep repeat customers happy is through offering generous loyalty programs. Through these programs, customers set up a free account with a certain airline that collects miles (i.e. points) each time the customer flies with that airline.

While these points may sometimes be available to customers when booking through third party websites, this perk is generally reserved for customers who book flights directly through the airline’s website.

Customer Service for Delayed or Canceled Flights

When booking directly through the airline, customers tend to have an advantage in the face of a cancellation or flight delay as most major airlines want to keep customers happy so that they will continue to make future bookings with the airline. For customers that have to cancel or delay their travel plans for unforeseen circumstances, airlines will often offer refunds, flight vouchers, and more to keep customers.

Pro Tips on Finding the Best Flight Deals

Although utilizing some of the top flight search engines is a great way to save money on flights, travelers can save even more by using these simple tips and tricks to save big bucks.

Apply for Airline and Travel Agency Credit Cards

Almost all major airlines and online travel agencies offer credit cards that can earn customers hefty rewards when it comes to travel. Avid travelers looking to save big bucks so consider applying for a line of credit from airlines like American Airlines and Delta or online travel companies like Priceline or Expedia to enjoy perks like discounted tickets, complimentary upgrades, free airfare, and more.

For first time applicants, most credit cards offer free airline miles that are equivalent to the price of a roundtrip flight within the continental United States after spending a certain amount of money in the first three months after the card is issued. After the initial bonus, users can continue to earn airline miles on everyday purchases like groceries, gas, and more.

Skip the Travel Insurance

Although purchasing travel insurance can make some travelers feel at ease, the majority of travel insurance providers make it nearly impossible to file a claim in the event that a trip must be canceled or postponed. With the cost for most travel insurance plans being between 5-6% of the total ticket price, travelers can generally skip over purchasing travel insurance and put their money towards other things. For travelers concerned about running the risk of illness in another country, purchasing short or long term international health insurance is a much better option for avid travelers looking to gain some peace of mind.

Don’t Be Afraid to Book!

While we certainly understand that it may be tempting to keep waiting for the absolute lowest price on airline flights, waiting too long to book may actually do more harm than good when it comes to booking travel. One of the biggest misconceptions about booking travel is that prices are lowest on Tuesday mornings, but this myth has largely been debunked.

Although prices for flights fluctuate daily, flight deals and discounts are available seven days a week and travelers who find a good deal shouldn’t wait to book as the price will likely increase the longer you wait. Travelers are encouraged to book flights in their price range once ticket prices drop below average gas prices fluctuate often and tend to change quickly. If a price seems too good to be true, book immediately!

By utilizing many of the online search engine features like price alerts, low fare calendars, and more travelers can rest assured they are always getting a fair deal on their fare.

With so many options for booking online travel, it’s easy to get overwhelmed when trying to find the best deal on flights. For travelers who are ready and willing to put in a little effort when it comes to booking their own vacation, these top travel sites can offer some of the steepest discounts around for vacationers looking to book a memorable once in a lifetime getaway.
