To get a Google Flights price alert, search for a route and turn on Track prices. Google then emails you when the price for that route or flight changes significantly. For a flexible trip, track Any dates. You find and stop your alerts on the Tracked Flights page. Price alerts are part of Google Flights itself, so a proxy has no part in them.
How to set up a price alert
Google's own steps, in order:
- Go to Google Flights.
- At the top, choose the number of stops, the cabin class and how many tickets you need.
- Choose your departure airport and your destination.
- Turn on Track prices. You can track your searched dates or, if your dates are flexible, "Any dates".
- To track one flight only, choose your flights first, then turn on Track prices.
You can also turn on tracking from the price graph, which shows fares by month or by week.
What the emails tell you
Google describes three kinds of email:
| what you track | when Google emails you |
|---|---|
| a route or a flight on your dates | when its price "changes significantly" |
| a route on "Any dates" | when "the route's minimum price drops significantly over a month"; otherwise "a regular email with the best available flight prices" |
| any route or flight you track | when prices "are likely to go up", or when the current fare "expires soon and the new fare is likely to cost more" |
The last kind comes with "an estimate of how much prices are likely to go up and our confidence in each estimate".
Find or stop your alerts
Go to the Tracked Flights page. Click a saved route to see the flights you track. Click Add notification to turn the tracking emails on or off. Click Remove to stop tracking a route or a flight.
Read the price tips first
Google Flights shows tips next to the results, and they can save you an alert you do not need:
| tip | what Google says it means |
|---|---|
| "Prices are unlikely to drop before you book" | Google predicts, "with a high degree of confidence", that the price will not fall before the flight leaves. |
| "Prices are less than usual" | the trip costs "significantly less than expected", judged against past prices of similar trips. |
| "Prices are likely to increase" | the tip says by roughly how much, and Google shows it only when it has high confidence. |
Each prediction rests on past price trends, and Google warns that future prices may not follow them. The Dates view shows which days are cheapest, and the Airports section may show that fares are cheaper at other airports. Google compares offers from "over 300 travel partners", and it says "Results may not reflect all available offers."
AI Flight Deals
Google calls a flight a deal when its price is "significantly lower than the typical price for a similar trip". The typical price is the median of the cheapest prices on that route over the past 12 months, "taking into account factors like the time of year, trip length, and cabin class". A price at least 20% below it gets a "% less than usual" badge, with the typical price crossed out. Google warns that "deals are subject to availability and the price you see may change when you go to book". It calls the feature "an experimental (beta) feature". Google says it may not return results yet for multi-city trips, infants, groups larger than four or set layovers.
What changes by country
Google Flights takes its default location from "your computer's location and your browser settings". Google says the location you choose may change three things: the booking partners, the payment methods and the refund policies. In the United States, for example, "you usually have 24 hours to change or cancel a flight without a fee". You can change the location, language and currency at the bottom of the Google Flights page.
Whether the fares themselves change by country, and why Google may block a VPN, is on our Google Flights page.
Where a proxy fits
For price alerts, a proxy does not fit. Track prices runs in Google Flights itself, and location is a setting at the bottom of the page. For collecting fares in bulk, our Google Flights page sets out what Google's terms and robots.txt allow.
For other work where a proxy is allowed, what a residential proxy is explains the type. Residential traffic without city targeting starts at $0.44/GB, and every plan is on our pricing page.
The limits of this page
We read Google's Travel Help articles from our server in St. Louis on 4 October 2026, and Google Flights answered that server normally. We did not sign in or set an alert, so what the emails contain is in Google's words, not ours. Google can change Track prices and its tips at any time, and AI Flight Deals is a beta. This page is due for a check by 4 January 2027.
