Worried you might book your flight at the wrong time and end up overpaying? Enter KAYAK Price Alerts and Price Forecast.
Our flight price tracking tools remove the guesswork from buying flights. Price Forecast gives you data-backed price predictions, while Price Alerts notify you automatically when prices go up or down. Here’s how to use these flight price trackers to save on your next flight.
How can I track flights with Price Alerts?
KAYAK Price Alerts let you know when prices go up or down on flights, so you can make the right decision about when to book.
How can I set a flight Price Alert?
Create and manage Price Alerts in the Price Alerts section of your KAYAK profile. Or you can do it on the fly as you search flights:
- Step 1: Go to KAYAK’s flight search
- Step 2: Toggle on “Track prices” in the upper left of your flight results page
- Step 3: Get automatic price updates straight to your email inbox or phone.
Note, you will need to sign in or create a KAYAK account before you can set up any Price Alerts.

What’s Price Forecast?
Price Forecast uses past data to guess the best time to book flights. Price Forecast can help you figure out whether you should buy now or wait.
Unlike Price Alerts, you don’t need an account for this, and you won’t get email notifications. Instead, you’ll see this prediction on most flight search pages while you search – both on our website and on our app.
How to save cash using flight price tracker tools.
Now you know the difference between Price Alerts and Price Forecast. Here’s how to use them to book the best flights for your next trip.
1. Track airfare for specific dates.
If you have a destination and travel dates in mind, start by picking the departure and destination airports, then your dates. Once you’ve run the flight search, turn on the Price Alert.
This will tell us to keep an eye on that route for those exact dates, letting you know when prices go up or down, as well as if they stay the same.
2. Keep an eye on airfare for a specific destination.
Maybe you know exactly where you want to go (hello, Amsterdam!), but you’re not too worried about when, as long as you get a good deal. If a low price matters more to you than the departure date, you can set up a Flexible Flight Price Alert.
You’ll get notifications for that route with the lowest price during the time you picked (if it was “Anytime,” travel is usually within the next 8 months). This is often a win for long-haul flights, which can sometimes see bigger price swings.
3. Keep an eye on airfare to the most popular cities.
What if you just need to escape? If where and when don’t matter, set up a Top 25 Cities KAYAK Price Alert. Choose from the US, Europe, the Caribbean, Central America, or South America.
Then, similar to a Flexible Price Alert, you’ll get notifications with travel deals to popular cities in that region like Reykjavík, Cancún, or Miami.
4. Predict prices for when you want to travel.
Say you want to go on a summer vacation and know the destination and time you’d like to travel – but are stuck on the best time to book.
Run your flight search on KAYAK as usual and check out the Price Forecast prediction – buy now, for example, or wait. If the price isn’t right, turn on a Price Alert and let us do the hard work for you.
Flight Price Alerts FAQs.
KAYAK tracks prices for the route and travel dates you choose and records when fares rise, drop, or stay the same. If a price changes, we send you an alert.

KAYAK Price Alerts are notifications – they won’t make purchases for you. You’ll be notified if the price changes, and then you can decide whether or not to make a purchase.
Price Alerts don’t tell you which days are cheapest to fly. Instead, they simply alert you when a flight price drops. Check out this article on the cheapest days to fly domestically or internationally.
Once you know you’d like to go somewhere, run a flight search and set up a Price Alert. This way, you can sit back and relax while KAYAK tracks prices for you.
