Google Flights has announced a new feature allowing users to view the cheapest flight options by introducing a "Cheapest" tab. This change will sort all flight options based purely on price, taking into account trip length, stops, and travel times. The feature aims to provide users with absolute lowest prices, including long layovers or mixed-and-matched flights from different airlines and travel agencies.
