Google Flights introduces price guarantee feature for travelers.
Google is testing a new pilot program for airfare rebates that will allow users to receive a refund if the price of their flight drops after booking. Domestic US flights and some international flights departing from the US will show up on Google Flights with a new price guarantee badge. The flights need to be bookable through the existing "Book on Google" feature, which confirms the itinerary on the traveler's behalf with the airline. Alaska, Hawaiian, and Spirit Airlines are the main Book on Google partners during the pilot phase.
