Google's AI model, Gemini, can streamline flight booking by providing tailored options based on user preferences like budget and travel dates. Users can enable the Google Flights extension to access real-time flight data and ask Gemini specific questions to find the cheapest flights. After receiving suggestions, users can refine results, set price alerts, and even export data for group planning. While Gemini offers a helpful starting point, users should verify prices directly on Google Flights.
