Google Flights has a New Deal for Travelers

All you have to do is set up an account to get that money back.

Good news for travelers…booking a flight through Google could get you a refund…if the price drops before you takeoff. This is a part of Google’s new pilot program.
When booking through Google Flights, select domestic and some international flights will have a price guarantee badge. This lets customers know that the company is “confident” that the ticket price is the lowest it can be…before takeoff. If the price drops in the time between your flight…Google will refund you the difference. All you have to do is set up an account to get that money back.
