Google announced Flight Deals, a new AI-powered search tool now in beta within Google Flights - currently rolling out in the US, Canada & India. Here's the pitch:

"Flight Deals is designed for flexible travelers whose number one goal is saving money on their next trip. Instead of playing with different dates, destinations and filters to uncover the best deals, you can just describe when, where and how you’d like to travel — as though you’re talking to a friend — and Flight Deals will take care of the rest."

They are keeping the original Google Flights.
