To set up a Google Flights price alert, search for your route and dates, toggle the “Track prices” button at the top of the results, and choose between tracking specific dates or any dates. You will receive an email whenever prices change significantly for that route. The alert system is free, requires no app download, and works for both specific itineraries and flexible date searches. Here is exactly how to use it, what the different alert types do, and what the tool cannot do for you.
What Google Flights Price Alerts Actually Do
Google Flights price alerts are email notifications that tell you when the price of a flight changes. They are not booking tools. They do not book tickets for you, and they do not guarantee you will get the lowest price. They simply monitor the fare for a specific route and send you an email when the price drops or rises beyond a certain threshold.
Google calculates the “typical” price range for each route based on historical data. When the current price moves above or below that range, the alert triggers. The email includes the new price, a link to the search results, and sometimes a note about whether the price is low, typical, or high compared to the average.
You can set up alerts on the Google Flights website or through the Google app. Both work the same way, but the web version has more filter options and is easier to use for complex searches.
How to Set Up a Price Alert
Setting up a price alert takes about thirty seconds. Here is the step-by-step process:
- Go to Google Flights — Open flights.google.com in your browser or open the Google app and search for flights.
- Enter your route and dates — Type in your departure airport, destination, and travel dates. You can also search without dates by selecting “Flexible dates” to see the full month view.
- Click the “Track prices” toggle — This appears above the results grid, near the date and airline filters. It is a small switch that you slide to the “on” position. When you enable it, the button text changes to “Tracked” and the alert is active.
- Check your email — Google will send a confirmation to the email address linked to your Google account. No further action is required.
- Wait for notifications — You will receive an email whenever the price changes significantly. The emails do not have a specific schedule; they arrive when the price moves enough to trigger the alert.
If you want to track multiple routes, repeat the process for each one. There is no limit to the number of alerts you can set up, and they remain active until you manually turn them off or delete them.
To turn off an alert, return to the Google Flights search, find the alert in the “Tracked” tab, and toggle the switch off. You can also click “Manage alerts” from any price alert email to see all your active alerts and delete them in bulk.
Types of Alerts: Specific Dates vs. Any Dates
Google Flights offers two types of price alerts, and the difference matters for how you use the tool.
Specific dates alert. This tracks the price for a fixed set of outbound and return dates. You enter your exact travel dates, and Google alerts you when the price changes for that exact itinerary. This is useful if your travel dates are fixed, such as a wedding or a conference. The alert will only trigger for those specific dates. If the price drops for a different date, you will not be notified.
Any dates alert. This tracks the price for a route without locking you into specific dates. You enter your departure airport and destination, but leave the dates blank or select “Flexible dates.” Google will monitor the entire calendar and notify you when prices drop for any date within the next six months. This is useful if you have flexible travel dates and want to book when the price is lowest. The email will highlight the cheapest dates and give you a price graph for the next few months.
To use the any dates alert effectively, search for your route without selecting dates. Google will show you the price graph for the next six months. Toggle the “Track prices” button, and you will get alerts for the whole range.
The any dates alert is more powerful for budget travellers because it gives you a longer window to catch a deal. The specific dates alert is better if you have a fixed schedule and want to know when to book within that window.
What the Emails Look Like
The price alert emails are simple and informative. They include:
- The new price — The current fare for your route.
- The old price — The previous fare that triggered the update.
- The price change — How much the price went up or down, in both dollars and percentage.
- Price status — A label like “Low price,” “Typical price,” or “High price” compared to the historical average.
- A link to the search — A direct link that opens Google Flights with your route and dates pre-filled.
- Price history graph — A small graph showing price trends for the route over the past 60 days.
The email is straightforward and does not require you to click through unless you want to book. You can read the price change directly from the notification and decide whether to act.
Google sends these emails from the standard Google Flights address, so they should not go to spam. If you stop receiving alerts, check your spam folder and add the sender to your contacts.
The frequency of emails depends on how often the price moves. During volatile periods, you might get several emails a week. During stable periods, you might go weeks without a notification.
What Google Flights Alerts Cannot Do
Google Flights price alerts are useful, but they have significant limitations. The most important is that they do not track prices across multiple airlines in a way that lets you compare itineraries. The alert monitors the specific itinerary you searched for. If you search for a nonstop flight on American Airlines, you will only get alerts for that specific flight. A cheaper option with a layover on Delta will not trigger an alert.
The second limitation is that the alerts are not instant. Google sends alerts in batches, not in real time. A fare drop that happens in the morning might not result in an email until the afternoon. On popular routes with high demand, a seat sale can sell out in a few hours, and the delay might mean you miss the deal. This is a known limitation, and Google’s own documentation acknowledges that the alerts are intended for planning, not for last-second deals.
The third limitation is that the alerts do not book the flight for you. You receive the email and still need to go to the website, find the fare, and complete the booking. In the time between receiving the email and completing the purchase, the price can change again.
The fourth limitation is that the alerts are only available for flights that Google Flights can search. If you are looking for a flight that involves a small regional carrier or a charter airline that Google does not index, you will not get alerts.
The fifth limitation is that the alerts are only for the first search result. If you search for a route and Google shows multiple itineraries, the alert is for the one displayed in the main column, not for every possible combination. To track multiple airlines or itineraries, you need to run separate searches and set up separate alerts.
How to Use Price Alerts Effectively
To get the most out of Google Flights price alerts, follow these practices:
- Set alerts early. Set alerts as soon as you know your destination, even if you do not know your exact dates. This gives you a longer window to catch a good price and helps you understand the typical price range for your route.
- Use both alert types. Set a specific dates alert for your preferred travel window and an any dates alert for the route as a whole. This gives you coverage for both the fixed and flexible parts of your planning.
- Monitor the price history. Look at the price graph in the alert emails to understand when the route is typically cheap or expensive. This helps you decide whether a price drop is a genuine deal or a return to normal after a temporary spike.
- Act quickly on low-price alerts. When you get a low-price alert, check the fare immediately. The cheapest seats can sell out quickly, and the price may not stay low for more than a few hours or a day.
- Check the fare rules. The price alert tells you the fare, but not the fare rules. Before you book, check the cancellation policy, baggage fees, and seat selection costs. A cheap fare with high add-on costs might not be as good as a slightly more expensive fare with better terms.
- Turn off alerts after booking. Once you book, turn off the alert to avoid clutter in your inbox. You can do this from the “Tracked” tab on Google Flights or from the “Manage alerts” link in any alert email.
Insider tip: Use the “Insights” tab on Google Flights to see the price history for your route and get a recommendation on whether to book now or wait. Google will tell you if the current price is low, typical, or high compared to the historical average. This insight, combined with the price alert, gives you a much clearer picture of when to book.
Honest Downsides: When Price Alerts Fail
The biggest downside is the delay. Google sends alerts in batches, and on popular routes with high demand, the fare can change before you get the email. If a seat sale starts at 9 AM and sells out by 11 AM, you might not get the alert until 1 PM. This is a frustrating limitation, and it is the reason why price alerts are better for planning than for last-minute deals.
Another downside is that the alerts only track one itinerary at a time. If you are flexible about your airline or layover, you need to set up multiple alerts for different itineraries. This is time-consuming and makes it harder to compare options.
Finally, the alerts rely on Google’s price data, which can sometimes differ from the airline’s own pricing. On rare occasions, you might get an alert for a price that is not bookable when you click through. This is infrequent, but it does happen.
Frequently Asked Questions
How do I turn on price alerts for all dates?

Yes. Google Flights covers most international routes. The alerts work the same way regardless of the departure or destination country, as long as Google has the flight data. The emails will be in the language of your Google account.
How often does Google Flights send price alerts?
Google sends alerts whenever the price changes by a significant amount. There is no fixed schedule. You might get several alerts in a week during volatile pricing periods or one alert a month during stable periods.
Are Google Flights price alerts free?
Yes. The alerts are completely free. You do not need to pay for the service, and there is no limit to the number of alerts you can set up.
Can I get price alerts on the Google app?
Yes. The Google app (on both Android and iOS) supports price alerts. The setup process is the same as on the web version. You will receive notifications directly on your phone in addition to email alerts.
How do I delete a price alert?

Google Flights price alerts are a free and effective tool for monitoring flight prices, but they are not real-time booking tools. The delays and the single-itinerary limitation mean they are best used for planning and early-stage research, not for snagging a fare that might disappear in minutes. Set alerts early, monitor the price history, and act quickly when a genuinely low price appears. If you use the alerts alongside flexible date searches and the insights tool, you will significantly improve your chances of finding a good deal.
