If your travel dates can move by a day or two, or even a week, Google Flights can show you which dates are cheapest instead of making you search one date at a time. Shifting a trip by a single day often saves a noticeable amount. This guide shows every flexible-date tool in Google Flights: the price calendar, Date grid, Price graph, Explore for flexible trips, and price tracking.
Quick Answer
On google.com/travel/flights, enter your departure and destination cities, then click the departure date box. The calendar shows a price under each date, with lower fares in green. Pick the cheapest pair of dates, or click Date grid or Price graph at the bottom of the calendar to compare combinations of departure and return dates.

Method 1: The Price Calendar
- Go to Google Flights and choose Round trip or One way.
- Enter where you’re flying from and to. You can add several airports or a city to widen the search.
- Click the departure date field. A two-month calendar opens with the lowest price for each date.
- For round trips, the prices shown assume a trip of a certain length. Use the − / + controls above the calendar to change the trip length (for example, 5-day trips).
- Click your departure date, then your return date, and click Done.
Scroll forward to see prices several months ahead.
Method 2: Date Grid
The Date grid compares many departure and return date combinations at once.
- After entering your trip, open the date picker and click Date grid (it also appears above search results).
- Departure dates run along one side and return dates along the other. Each cell shows the price for that combination, with the cheapest highlighted in green.
- Use the arrows to move the grid by a few days.
- Click a price to select those dates.
Method 3: Price Graph
- Click Price graph in the date picker or above the results.
- A bar chart shows prices across about two months for your trip length.
- Hover over a bar to see the dates and price; click to select them.
- Adjust trip length with the controls to see how a longer or shorter trip changes prices.
Method 4: Explore for Fully Flexible Trips
If you don’t have fixed dates, or even a fixed destination:
- Click Explore on the Google Flights home page (a map view).
- Enter your departure airport, and leave the destination blank or type a region (like “Europe”).
- Click the date box and choose the flexible option, where you can pick a trip length (such as a weekend, one week, or two weeks) and a month or range of months instead of exact dates.
- The map shows the lowest prices to destinations for those flexible dates. Click one to see dates and flights.
Method 5: Track Prices
- After searching, turn on Track prices above the results. Google emails you when prices change significantly for those dates.
- For a route without fixed dates, look for the option to track any dates for that route, which alerts you to good deals over the coming months. Availability of this option varies.
- Manage tracked flights under Tracked prices in the Google Flights menu.
Use Price Insights
Below the search bar, Google Flights may show a price insight like “Prices are currently low” or “typical” for your search, with a history chart. It may also suggest cheaper nearby dates or airports. Use these as guidance; they’re estimates based on past prices.
Tips for Finding the Cheapest Dates
- Midweek departures (Tuesday and Wednesday) are often cheaper than Friday and Sunday on many routes, but check the calendar for your route rather than assuming.
- Include nearby airports (for example, add all airports in a city) for more options.
- Check one-way prices for each direction; two one-way tickets are sometimes cheaper than a round trip.
- Remember to check baggage fees. Google Flights lets you add bags to the search so prices include them.
- Prices change often, so book when you see a good fare rather than waiting for a perfect one.
