As the award prices load, Points Path indicates whether using miles is a good or great deal for each flight, or if you should use cash instead. And if a flight isn’t available with points or miles, Points Path will show that too.
Click the "i" icon under any award amount, and a Points Path popup will appear showing all the available airline programs that can book that flight, along with any credit card points that can be transferred to those airlines.
If you find a flight you’d like to book using points or miles, just click on it. You’ll see the standard Google Flights booking page, but Points Path will also add a link to book the flight with points or miles.
