Google Flights is web-based travel search engine that helps users find & compare flight fares. It is powered by Google's search technology and is designed to make it easy for users to search for flights.
Google Flights works by searching databases from each airline & online travel agency to find flight schedules, seats, and prices. It works by using a program called ITA Matrix.
Users can search for flights using various criteria, such as departure and arrival locations, dates & number of passengers. The results show a list of flights, prices & other details.
Airlines are listed on Google Flights, include United Airlines, Delta Air Lines, British Airways, Air France, KLM Royal Dutch Airlines, Singapore Airlines and many more.
Several large Asian carriers, including Thai Airways and Philippine Airlines are notably absent from Google Flights. Additionally, in the US the most glaring omission is Southwest.
Google Flights does not set or control the prices of flights. But, it's possible that Google Flights may show cheaper prices due to the way it searches & displays flight data.
Google Flights also offers price tracking, which allows users to receive notifications when the flight price change & flexible dates option, which enables users to search for flights across a range of dates.
