Jetstar is going the way of Orbitz, sort of, with its price alert system. The low cost carrier recently launched Price Watch, a tool that alerts you when the flight you’re after sees a drop in price, saving you the hassle (and stress) of having to check the prices religiously in hopes of snagging a better deal.
After you pick your flight, click the “Watch Prices” button and enter your desired price, email address and number of passengers travelling. Once the prices drop to or lower than your ideal price, you’ll get an email alert. Jetstar also has a Price Beat Guarantee, meaning if you can find a lower fare online, of the same route (flying the same date and time), just start an online chat with their customer service team and they will beat the price by 10%.
