Method 1: Google Flights
The Google Flights are using the ITA Matrix Software and the flight search engine. It should have to return the same results in theory. The only thing which is different here is that Google Flight’s matrix will let you book and purchase the flights. Searching for the flights on Google Flights is very easy and you can also compare the fare with all the other booking engines like Orbitz and Kayak.
So why to use the ITA Matrix? Simple it will offer more advanced searching functionality than the google flights matrix such as the advanced routing codes or the nifty calendar of fares. Whatever search result you will get on the ITA Matrix, plug that all into the Google Matrix Flights.
Go to the Google Flights – The default is the round trip, but there is the option for choosing the one-way and multi-city if you like. Enter the Depart from and the Destination city. You can also pick the number of passengers and the cabin type which you would like on ITA Matrix.
