Getting notified when there’s a deal to be seized is one of the simplest yet most effective ways to ensure you get the cheapest plane ticket possible.
There are a surprising number of sites and apps to set these alerts up, whether specific to certain destinations and travel dates or more general for all the cheapest flight options from your nearest airports.

Best Ways to Get Cheap Flight Alerts
1. Going (Formerly Scott’s Cheap Flights)
Going (Formerly Scott’s Cheap Flights) is one of the original travel deal websites and one of the best to visit if you want the best flight deal alerts. It’s one of our top choices at ViaTravelers and a favorite around America.
The concept is very simple – sign up for a free account and enter your home airport and any others you’d like to receive deals from. Then, watch the deals roll in! Going will email you when a great deal becomes available. If you like what you see, you’ll book flights directly with the airline, as Going is just the messenger.
Going searches for both round-trip and one-way tickets, and results will contain anything their experts consider a great deal – you won’t need to set up preferences for specific flights or dates.
Upgrading to a premium plan gets you access to more deal types, such as domestic flights, mistake fares, and more. Read our full Going (Formerly Scott’s Cheap Flights) Review for more information.

This is another site that is constantly searching for cheap airfare on routes around the country and sending you a price alert every time one corresponds to you.
The fares they locate are usually between 60 and 90 percent below usual, and they claim that members save an average of $500 thanks to this. Premium members get access to more exclusive deals like mistake fares and domestic deals. Booking one flight after signing up could get you a ten-times return on investment.

Kayak has long been of the most user-friendly platforms for frequent fliers. This flight search engine aggregates prices from almost any airline and a range of online travel agencies, ensuring that whoever is offering the lowest prices is visible to you.
Besides being a great site to perform searches, Kayak also has a free flight price tracker function. Travelers love how flexible the monitor is – if you don’t know where or when you want to travel but want to receive price alerts any time there’s a great deal, activate the Top 25 Cities alerts if you have a destination in mind but aren’t set on dates, set up a price alert with flexible dates.
However, you can also make it much more specific. Simply perform a search with your preferred travel dates (including any specifications you might have; for example, add nearby airports or specify that you only want to fly nonstop). On the search results page, click the button to track prices – you’ll get notified every time prices change so you can book at their lowest.

Momondo is another long-time favorite for searching not only flights on any airline to any destination but also for all of the hotels and rental cars available there. Travelers love its user-friendliness, similar to Kayak’s – probably because Kayak owns it and works on the same technology!
Once you perform a search, whether one-way or round-trip, you can easily flip the Price Alert switch on both the app and the website.
Making a (free) account is the easiest way to manage your tracked flight prices, allowing you to shut off notifications you no longer need. However, don’t do that until you are certain – you never know when you’ll be pleasantly surprised with a last-minute flight alert!

Expedia was founded in 1996, making it one of the true original online travel sites, and it’s one of the biggest for travel deals and vacation packages. Cheap flights are available in their hundreds, and Expedia goes the extra mile to secure even further discounts if you book directly through their site.
Its price alerts function rolled out in 2006, making it a pioneer in this specialty. Set your departure airports, arrival destinations, dates, and other parameters, and Expedia will constantly check to see if prices change, informing you instantly.
While you can often find a great flight price when booking directly with Expedia, you can almost always find that same deal on that flight directly with the airline – this is the safer option if things go wrong. However, a truly great flight deal is hard to pass up, so if you must book with Expedia, know how it works and what to expect.
10. Jack’s Flight Club
Jack’s Flight Club is another site with real humans working round the clock to find the cheapest flights and share them with its members.

Have you noticed the ridiculousness of some flight pricing logic? For example, I searched for flights from Las Vegas to Honolulu and found the direct flight was outrageously expensive. Then, I searched Vegas to Maui instead and found that I’ll pay about half the price if I took that same flight to Honolulu and connected to Maui.
So, why not just book that last route, and skip the connection? That’s called skiplagging or hidden city ticketing, and it is possible. Although it is frowned upon, or in some cases prohibited, by airlines, it’s hard to stop people from doing such a thing – and saving money.
Skiplagged is a site that gets rid of the work of searching endless destinations in an attempt to get you to your real one. It’s great for that and adds even more value with its price alerts feature – activate the option on your search to watch a fare and wait for a notification that there’s a new price.
