Google’s “Price Guarantee” is a flight tracking service designed specifically for consumers. When you book a flight through Google Booking and see the “Price Guarantee” badge, Google will continuously monitor that flight’s price until the first flight of your itinerary departs. If the price drops during this period, Google will refund you the difference through Google Pay!


2️⃣ Price Guarantee Coverage

Currently, the “Price Guarantee” program primarily applies to one-way and round-trip flights departing from the United States, and is limited to select partner airlines (such as Alaska Airlines, Hawaiian Airlines, and others).
