According to a report from Android Police, it seems that Google has rolled out a new Google Now card that allows users to track flight prices for a particular destination. The card, as you can see in the screenshot above, will display the prices and the fluctuations so that you will know that perhaps today’s deal is cheaper than a few days ago.
However it should be pointed out that this feature only seems to work through Google Flights for now, so if you use other flight services to track ticket prices, you will not be able to take advantage of this new Google Now card. Perhaps this will change at a later date, but for now it looks like it is a Google Flights exclusive.
Also it is not clear how widely available this card is at the moment. Google has a habit of rolling out experimental features to a limited group of users for testing before they make it widely available, as was the case with the bill reminder feature, but if you have noticed the new Google Now card on your Android device, do let us know in the comments below!
