Key takeaways
- In AyeWatch you paste the fare page, write the price you want in a sentence, and get a push alert on any plan.
- Google Flights, Kayak and Skyscanner each let you turn on tracking from a search, with alerts by email and, on Skyscanner, in the app.
- Pair a page alert with a search-site alert when you also want to compare many airlines and dates.
Here is how to set flight price alert notifications: open the route or fare page you want, turn on tracking, and choose where the message should reach you. The quickest way to cover any airline's own page is AyeWatch: paste the link, write the price you are waiting for in a sentence, and it pings your phone when that happens.
Below are the exact steps for AyeWatch and for the three search sites most people already use, so you can pick the one that matches your trip.
Short answer by situation
| Your situation | Best way to set the alert |
|---|---|
| A specific airline page, budget carrier or one cabin | AyeWatch, with a rule in plain English |
| A popular route with fixed dates | Google Flights tracking |
| You want a hint on whether to buy now | Kayak, which shows a Price Forecast |
| You already search on Skyscanner | Skyscanner price alerts, after logging in |
How to set a flight price alert in AyeWatch
- Go to the airline's site, search your route and dates, and copy the page address.
- In AyeWatch, start a new topic and paste that address.
- Type the condition the way you would say it to a friend: "Alert me if the Lisbon to Boston fare on 4 June falls under $450."
- Keep push notifications on. They work on every plan, the free preview included. If you want the alert in email, Slack, Discord or a webhook, those come with a paid plan.
That is the whole setup. When the page changes in the way you described, the alert arrives with a short summary of what moved. Once you have booked, pause or delete the topic.
AyeWatch runs on the web, iOS and Android. The free preview needs no card, and paid plans start at $9 a month, billed in monitoring credits.
How to set one on Google Flights
Search the route, then switch on price tracking for the route or for one flight. Google's help page says you get email updates when the price changes significantly. If your dates are loose, choose "Any dates" and Google watches the route's lowest fare across a month instead.
How to set one on Kayak
Run a flight search. If Kayak has enough data, it shows a Price Forecast such as "book now" or "wait". Toggle on Price Alert and Kayak emails you when the price changes.
How to set one on Skyscanner
Log in first; Skyscanner needs an account for alerts. Search your route and dates, then use the track prices option on the results page, or the bell icon in the app. Alerts come by email or as an app notification. Note that the alert keeps your route, dates, travellers and direct-only choice, but not most other filters.
Which one should you use
For most people the answer is two alerts, not one. Use AyeWatch as your main alert because it works on any page and lets you state the exact condition, and add a Google Flights or Skyscanner alert when you also want a broad search across many airlines and dates. That broad comparison is the one job where a dedicated flight tool beats a page monitor.
Tips that save money
- Put the price limit in the rule, not just "tell me if it changes". You get fewer, more useful alerts.
- Watch the return and one-way fares separately if the airline prices them that way.
- Pause alerts after you book, so your phone stays quiet about a trip that is already paid for.
