Google Flights introduces price guarantee for cheaper tickets.

Google Flights is testing a price guarantee program in the US that will refund the difference if the price of a flight booked through the service drops. The feature is only available for specific flights and only for those departing from the US. The refund is limited to $500 per calendar year and will only be given if the price difference is more than $5. The refund will be given through Google Pay, and the service must be set up within 90 days of notification.
