Has anyone used the app Google Flights?
It is supposed to search many flights in a short amount of time and give you the results you want. After all, that's what you would expect from Google.
I've looked at it and it shows a map with prices of flights from your home base. You can even pick a non-specific destination like California or Western Europe and it shows a map of airports in that area with the cheapest flights. It gives better dates to fly for the same or lower prices as well.
These are supposedly the best flights...not always the cheapest, based on Google info.
This app is free and users tell me it works great. Let me know if you've used it and what you thought of it.
