Bottom line: Google Flights and Skyscanner are two of the best sites for searching for flights. Both have some great functionality, but each also has some areas for improvement. That's why we often recommend pairing multiple search sites to ensure you're getting the best deal.

For the vast majority of travelers in 2026, Google Flights is widely considered the best starting point and overall tool for airfare research. Its primary advantage is its speed and "direct-to-airline" integration; unlike traditional Online Travel Agencies (OTAs), Google Flights aggregates data in real-time without adding its own fees. It offers powerful features like the "Track Prices" toggle, which sends email alerts for fare drops, and the "Explore" map that shows the cheapest destinations from your home airport. However, it is not perfect. It often misses "ultra-low-cost" carriers like Southwest Airlines in the US (though this is improving) or specific regional charters. Furthermore, while it is the best for finding flights, savvy travelers always use it to identify the itinerary and then navigate directly to the airline's official website to book, as booking direct provides better protection for cancellations and changes than any third-party aggregator can offer.
