How to Use Google Flights to Find Cheap Flights

Google Flights is the best free tool for finding cheap flights. Use flexible date searches, price tracking, and explore maps to save 30-50% on airfare. Set up alerts and book directly with airlines.

1. Start with flexible dates. Enter your departure city and destination, but leave dates blank. Click the calendar and select 'Flexible dates' to see a price grid. Tuesday-Thursday flights are typically $50-200 cheaper than weekend travel.
2. Use the explore map feature. Click 'Explore' instead of entering a destination. Set your budget (like $500) and see all places you can reach. Perfect for spontaneous trips or finding hidden deals to places you hadn't considered.
3. Track prices before booking. Click the toggle to 'Track prices' on any search. Google will email you when prices drop. Track 3-4 routes simultaneously. Prices typically fluctuate $20-100 daily.
4. Check nearby airports. Include nearby airports in your search - often saves $100+. For NYC, search 'New York area' not just JFK. For London, include all London airports. Drive an extra hour to save hundreds.
5. Use filters strategically. Filter by stops (nonstop costs 20-40% more), airlines (avoid budget carrier fees), and departure times. Early morning flights (6-8 AM) are usually $50-150 cheaper.
6. Book directly with the airline. Google Flights shows you options but links to airline websites. Never book through third parties - you'll lose customer service rights and flexibility. Airlines honor their own bookings better.

When should I book after finding a good price?

Domestic flights: 1-3 months ahead. International: 2-8 months ahead. If you see a price 20% below average, book it. Prices rarely get better once they hit that threshold.

Why don't I see Southwest or some budget airlines?

Southwest, Allegiant, and some international budget carriers don't appear in Google Flights. Check their websites separately. Southwest often has competitive prices on direct routes.

Are the prices I see on Google Flights final?

Usually yes, but airline websites may add $25-50 in fees that Google doesn't show. The price difference is still worth it for the booking protection you get from airlines directly.

How far in advance should I start tracking prices?

Start tracking 8-10 weeks before domestic trips, 12-16 weeks for international. Earlier tracking gives you better data on price patterns and more chances to catch deals.
