About Google Flights
Google Flights is arguably the smoothest flight comparison tool. Its date grid and price calendar instantly reveal the cheapest days to fly, price tracking warns you when a fare is likely to rise or fall, and the filters (stops, airlines, duration, even carbon emissions) are excellent. Like other metasearch tools it sends you to the airline or agent to book. Fast, free and clutter-free — ideal for quickly benchmarking a route.
