Why Google Flights Is the Best Flight Search Tool
If you want to learn how to use Google Flights, you are already ahead of most travelers. Google Flights is the most powerful free flight search tool available, and most people only use a fraction of its features. The Explore map, flexible date search, price tracking, and filtering tools can save you hundreds of dollars per trip.
Unlike booking sites like Expedia or Kayak that push sponsored results, Google Flights shows prices sorted by actual cost with no hidden fees. It pulls data from airlines and online travel agencies, giving you a complete picture of what is available. And because it is Google, the interface is fast, clean, and updated in real time.
This guide walks through every feature step by step, from basic searches to advanced techniques that frequent travelers use to find consistently cheap flights.
How to Use Google Flights Explore Feature
The Explore feature is the most underused tool on Google Flights, and it is the best way to find cheap flights when you are flexible on destination.
Step-by-Step: Explore Map
- Go to google.com/travel/explore
- Enter your departure airport (you can add multiple departure airports)
- Leave the destination field empty or type a region (“Europe,” “Caribbean,” “Asia”)
- Select your travel dates, or leave them flexible to see the cheapest time to go
- A map appears showing round-trip prices to destinations around the world
- Click any destination to see specific flight options and dates
Pro Tips for the Explore Map
- Zoom in on regions to see smaller airports and cities with cheaper flights
- Change the trip length (weekend, 1 week, 2 weeks) to see how prices shift
- Toggle “nonstop only” to filter out connection flights
- Set a maximum price to only see destinations within your budget
- Try different departure airports if you live near multiple airports. Flying from a secondary airport can save $100+.
The Explore map is perfect for “where should we go?” planning. Once you find a destination, build your full trip itinerary with Yopki’s trip planner and start planning activities, accommodations, and daily schedules.
Finding Cheap Flights with Flexible Dates on Google Flights
Date flexibility is the single biggest factor in finding cheap flights. Learning how to use Google Flights’ date tools can save you $100-$400 per round trip.
The Date Grid
After searching for a route, click the Date Grid button (calendar icon). This shows a matrix of departure and return dates with the price for each combination. The cheapest options are highlighted in green.
What to look for:
- Midweek departures (Tuesday, Wednesday) are almost always cheaper than weekend flights
- Returning on a Tuesday or Wednesday saves $20-$80 compared to Sunday returns
- Red-eye flights (departing late night) are often the cheapest of any day
- The date grid shows you exactly how much you save by shifting one day in either direction
The Price Graph
Click the Price Graph button to see a visual chart of prices across an entire month or season. This view shows:
- The cheapest departure date for your route
- Price trends (is the route getting more or less expensive?)
- Seasonal patterns (summer vs. shoulder season vs. winter pricing)
Flexible Dates Search
When entering dates, select “Flexible dates” instead of specific dates. Google will show options within a range, including:
- Cheapest dates this month
- Cheapest dates next month
- Best prices across the next 6 months
Setting Up Price Tracking Alerts on Google Flights
Google Flights price tracking tells you when to buy. Instead of checking prices daily, let Google monitor for you.
How to Enable Price Tracking
- Search for your route and dates
- Toggle the “Track prices” switch (usually near the top of results)
- Google sends email alerts when prices change significantly
What Price Tracking Shows You
- Current price vs. typical price: Google compares today’s price against historical averages for this route
- Price confidence: A green indicator means prices are low (buy now). A red indicator means prices are high (wait if you can).
- Price prediction: Google uses machine learning to predict whether prices will go up or down in the coming days
Best Practices for Price Tracking
- Set up tracking as early as possible (3-6 months before travel for international, 1-3 months for domestic)
- Track multiple date combinations for the same route to find the cheapest window
- Act quickly when you get a “prices are unusually low” alert. Fare sales often last only 24-48 hours.
- Track from multiple departure airports if you are near several
Multi-City and Open-Jaw Search
Knowing how to use Google Flights for multi-city trips saves money on complex itineraries that most booking sites handle poorly.
Multi-City Search
- On the Google Flights homepage, click “Multi-city” (below the search fields)
- Add each flight leg: City A to City B, City B to City C, City C to City A
- Google prices each leg separately and shows the total
Example: New York to London, London to Paris, Paris to New York. Multi-city search often finds combinations cheaper than booking each flight individually.
Open-Jaw Flights
An open-jaw itinerary flies into one city and out of another. For example: fly into Rome, take a train to Florence, and fly home from Florence. This eliminates backtracking and sometimes costs less than a round trip to one city.
To search open-jaw on Google Flights:
- Select “Multi-city”
- Flight 1: Home to Destination A
- Flight 2: Destination B to Home
- Compare the total against a round trip to either city alone
Open-jaw itineraries work especially well for European trips, road trips with a rental car, and cruise itineraries where the departure port differs from the arrival port. Plan your multi-city itinerary with Yopki’s trip planner to see how the cities connect.
Reading the Google Flights Price Graph
The price graph is one of the most useful tools for understanding how to use Google Flights strategically. It reveals patterns that help you time your booking.
What the Graph Shows
- X-axis: Dates (departure dates)
- Y-axis: Price (round-trip fare)
- Green dots: Dates with lower-than-average prices
- Gray area: Typical price range for this route
Patterns to Look For
- Weekly cycles: Most routes show a repeating pattern where Tuesday/Wednesday departures are cheapest
- Holiday spikes: Prices jump 2-4 weeks before major holidays and drop immediately after
- Seasonal trends: Summer and winter holiday prices are highest. Spring and fall (shoulder season) are lowest for most destinations.
- Event-based spikes: Concerts, festivals, and major sporting events cause localized price increases
Filtering Google Flights Results Like a Pro
Google Flights filters help you find flights that match your actual travel needs, not just the cheapest option with 3 layovers.
Stops
- Nonstop only: The fastest option but often the most expensive. Best for short domestic routes.
- 1 stop or fewer: The sweet spot for most travelers. Often $50-$150 cheaper than nonstop with only 1-2 hours added.
- Any number of stops: Shows everything. Useful for finding ultra-cheap fares if you do not mind long travel days.
Airlines
Filter by airline if you have loyalty status, a preferred carrier, or want to avoid specific airlines. You can select multiple airlines simultaneously.
Times
Slide the departure and arrival time bars to filter out flights that are too early, too late, or arrive at inconvenient times. This is especially useful for business trips or when you need to connect with hotel check-in times.
Duration
Set a maximum flight duration to filter out routes with excessively long layovers. A 5-hour direct route is better than a 14-hour route with two connections, even if the latter saves $30.
Bags
Toggle the “Bags” filter to include carry-on or checked bag fees in the displayed price. This is critical because a $200 flight with $70 in bag fees is more expensive than a $250 flight with free checked bags.
How to Use Google Flights for the Cheapest Booking
Once you find a flight, the final step is booking at the best price. Google Flights shows prices from multiple sources.
Where to Book
- Book directly with the airline when the price is the same as third-party sites. Direct bookings are easier to change, cancel, and get customer support for.
- Use a third-party site only when the price is significantly lower ($20+ savings). Be aware that changes and cancellations may be more difficult.
- Check the airline’s own website separately. Occasionally, airlines offer web-only fares or bundle deals not visible on Google Flights.
Before You Book
- Check what is included in the fare (bags, seat selection, changes, cancellation)
- Compare “Basic Economy” vs. “Main Cabin” fares. The $30-$60 difference often includes a checked bag, seat selection, and change flexibility.
- Verify the total price including all taxes and fees (Google Flights shows this, but always confirm on the booking page)
- Check if your travel credit card offers a booking bonus for that airline or portal
Best Time to Search and Book Flights
Timing your search and booking affects the price you pay. Here is what the data shows for 2026.
Best Day to Search
There is no single “cheapest day to search.” Prices change multiple times per day based on demand, and Google Flights shows you real-time pricing. What matters more is booking during a low-demand period for your route.
Best Time to Book by Trip Type
- Domestic flights: 1-3 months before departure
- International flights to Europe: 2-6 months before departure
- International flights to Asia: 2-4 months before departure
- Holiday travel: 3-4 months before (prices spike 6 weeks before holidays)
- Last-minute flights: Within 2 weeks. Prices are high for popular routes but occasionally drop for low-demand routes.
When NOT to Book
- Never book more than 6 months out for domestic flights (prices are not yet optimized and often drop)
- Avoid booking within 7 days of major holidays (prices are at peak)
- Do not wait until the last week hoping for a price drop on popular routes (it rarely happens)
Google Flights vs. Other Booking Sites
| Feature | Google Flights | Skyscanner | Kayak | Hopper |
|---|---|---|---|---|
| Price comparison | Excellent | Excellent | Good | Good |
| Explore/map feature | Best in class | Good | Basic | No |
| Flexible dates | Excellent | Good | Good | Limited |
| Price tracking | Good | Good | Good | Best (predictive) |
| Southwest included | No | No | No | Yes |
| Bag fee inclusion | Yes | No | Sometimes | Sometimes |
| Books directly | No (redirects) | No (redirects) | No (redirects) | Yes (in-app) |
The best strategy: use Google Flights as your primary search tool, then check Skyscanner for routes Google may price differently, and always check Southwest.com separately. Plan your trip with Yopki’s destination guides to decide where to go, then use Google Flights to find the cheapest way to get there.
Frequently Asked Questions About How to Use Google Flights
Is Google Flights the cheapest way to book flights?
Google Flights is a search engine, not a booking site. It compares prices from airlines and third-party booking sites and shows the cheapest available options. In most cases, Google Flights surfaces the same prices you would find booking directly. However, some budget airlines (Southwest, some international carriers) are not included in Google Flights results. For the most complete price comparison, check Google Flights alongside Southwest.com, Skiplagged, and the airline’s own website.
Does Google Flights track price drops?
Yes. Google Flights has a built-in price tracking feature. When you search for a flight, toggle on the Track Prices button and Google will send you email alerts when prices drop or rise for that route and date combination. Google also shows a price confidence indicator that tells you whether current prices are low, typical, or high compared to historical averages for that route.
How far in advance should I book flights on Google Flights?
For domestic flights, the best prices are typically found 1-3 months before departure. For international flights, 2-6 months ahead generally offers the best deals. Google Flights’ price graph feature shows historical price trends for your specific route, which helps you decide whether to book now or wait. Avoid booking less than 2 weeks before travel for domestic flights, as last-minute prices are usually the highest.
Can I search for flights without specific dates on Google Flights?
Yes. Google Flights lets you search with flexible dates in several ways. Use the Explore feature with no dates to see the cheapest time to fly anywhere. Use the Date Grid to compare prices across an entire month. Or select “Flexible dates” when searching to see options within a range of plus or minus 3 days. These tools are the best way to find the cheapest travel window for your trip.
Does Google Flights include Southwest Airlines?
No. Southwest Airlines does not allow third-party sites to display its fares, so Southwest flights do not appear in Google Flights results. If Southwest flies your route, always check Southwest.com separately to compare prices. Other airlines missing from Google Flights are rare, but some smaller regional carriers may not be included.
