I am using this plugin since 2 years and it’s perfect to find an airplane ticket all around the world !
It is easy-to-use and if you have a gmail address, you can set up some price alerts.
Some tips with Google Flight :
1. Don’t know exactly where to go? Search for a general area, and see a map of specific flight prices.
2.Google will tell you which flight is the best option for your purse.
3.It’ll also show you the lowest price for any given day on the calendar.
4.Automatically see tips that will save you money.
5.Once you find a flight, let Google flight monitor the price for you.
