"Google Fly" is more commonly known as Google Flights, and using it is a straightforward process designed to help you find the best value for air travel. To begin, navigate to google.com/flights and enter your departure city and destination. One of the tool's most powerful features is the "Track Prices" toggle, which sends you email alerts when fares for your specific route drop. If your dates are flexible, you can use the "Date Grid" or "Price Graph" to visualize which days offer the cheapest departures. For travelers with a budget but no set destination, the "Explore" map is an invaluable feature: simply leave the destination blank and browse the map to see the lowest prices to various cities worldwide for a set timeframe. Once you find a flight you like, Google usually redirects you to book directly with the airline or a partner site. As of 2026, the tool also incorporates AI-driven insights that predict whether a current price is likely to rise or fall based on historical data, helping you time your purchase perfectly.
