Yapta.com: The newest entrant in this burgeoning field. There are two things you can do here: first, if you've already bought a fare, you can enter the flight locator number and then you'll get an alert if the fare has gone down. (Some airlines will refund the entire fare difference in the form of a voucher good for future travel within a year; others deduct $25 to over $300, depending on the fare and route.) But there's also a "Tagger" feature where you can track fares on individual flights, not just routes between two cities.

A price alert tracks the price of a specific route or flight. When the price changes, you’ll be notified via email or push notification if the price went up or down (and by how much). Price alerts are completely free, can be stopped at any moment and you can have multiple set up at once. They are hands-down one of the best ways to find cheap flights, fast.


Sites in this latter category, which is growing at a rapid clip, may include a search component, but they also provide a list of low fares and/or alerts about such fares, either delivered by e-mail or posted online. They're ideal for people who are just looking for somewhere cheap to visit, or who are hoping to travel on specific routes but want to buy when fares are at their lowest. In alphabetical order, here are 10 of the best.

Most cash bookings can be upgraded with Avios either at the time of booking or later on, depending on availability. Only the lowest economy (World Traveller) fares (Q, O and G) cannot be upgraded with Avios at any time. There must be reward flight availability in the next cabin for you to be able to upgrade to it using Avios. You won’t be able to upgrade with Avios at the airport or on board.
I’ve included these two together in this instance as the startup team behind Yapta jumped on board with KAYAK back in February of 2010, and the two websites share a crossover of features and a similar design. The combination of Yapta and KAYAK probably offers the most powerful combination of features for tracking flight costs, but it can be a touch finicky to use and is not as intuitive as Google Flights.
You will be notified every time the price changes so you can best keep track. As there is no standard for how often airfare changes, there is no maximum or minimum number of times that you will be notified. Our goal is to keep you up to date and help ensure that you get the best deal available and the best way to do this is to notify you every time there is a price increase or decrease.

Watch for business-class sales. Most leisure travelers ignore advertised business-class fare sales entirely. I have occasionally seen transatlantic business-class sale fares for around $1,100 at a time when it costs that much to fly coach. This will take some persistence and sleuthing, but you can sometimes fly in the front of the plane for less than the folks crammed into the back of the plane.

I like Skyscanner.com because it has the open-ended “everywhere” option. You just type in your departure city (or general area such as your state) and in the destination box, you can select “everywhere.” What I don’t like about this option that it will only populate for departures from major cities. When I type in my airport, I have to click on each destination to get prices, a bit labor intensive. It does offer a nice map view of the entire world populated with the lowest-priced fares from any departure city. You can easily set up an alert for any combination of cities but not to “everywhere.”
Brandon was thrust into the world of points and premium travel as a university student, and has made the most of it since. Now graduated, working from Launceston and somehow a Velocity Platinum frequent flyer, he eagerly awaits for more opportunities to explore the world from the pointy end of the plane.You can find him on Instagram as @bloo.per, as well as running a food/travel account @flightandbites with his partner.
Airfarewatchdog.com: This is the only site in the group that lists and compares fares on Southwest Airlines (now the largest domestic carrier based on passengers boarded, but one that refuses to pay sites to send it traffic), as well as those on low cost carriers such as Allegiant and Skybus, which sell fares only on their own Web sites. Whereas the other sites listed here use computer programs to evaluate fares, Airfarewatchdog uses people, who actually test if seats are available at the fares listed (sometimes airlines file fares for which very few or no seats at all are available, which is very naughty of them).
The other nice thing about the results page is that it’ll show you connecting options (as long as you don’t limit it to nonstop flights at the outset), though bear in mind that every leg of a one- or multi-stop itinerary must have award availability in the desired class of service in order to book the entire trip with miles. Remember too that most award seat availability shown on ExpertFlyer will be at the saver level for all programs. This is nice in that it should be bookable using any partner program’s currency, but it won’t show you the expanded award inventory that’s sometimes available through certain programs.
Currently, only one member may sponsor an upgrade per reservation. For instance, if a Super Elite 100K and Prestige 25K member are travelling together on the same booking, it is not possible for the Super Elite 100K member to sponsor an upgrade for the departing flight(s), and for the Prestige 25K member to sponsor an upgrade for the return flight(s).

This information flow can be incredibly helpful when trying to book award seats not available online or with programs that have challenging phone agents. If you wanted to redeem Etihad miles for a business class flight from Prague (PRG) to Seoul (ICN) on Czech Airlines for the amazing price of 25,610 Etihad miles, don’t rely on hit-or-miss Etihad phone agents to find space; use ExpertFlyer and have the flight number and date in hand for this one-of-a-kind award flight:
Number 2 is that you don’t even need to know where you want to go. Based solely on your fixed dates or a broad time period, the Explore option shows you where is cheapest to fly, which is a perfect tool for the early stages of your trips. I use it this feature a lot when planning a trip itinerary or choosing which hub city should I adopt in a multi-city trip.
Kiwi’s interactive map feature is especially useful. Set your home city and look at the map to see how much different cities would cost to fly to. Once you select your destination, you can sort your results into either recommended, cheapest or shortest flight. Kiwi finds the cheapest pricing by pulling in different carriers, but you may have to book separate tickets — which shouldn’t be a problem for bargain hunters or those on a budget. For example, if you want to fly from New York (JFK) to Dublin (DUB), you could always fly nonstop on United, which you’ll find as a result in the ‘shortest’ category. But if you click on the “cheapest” category, you can book one leg from JFK to London (LGW) on Norwegian, and then a Ryanair ticket from London (LGW) to Dublin (DUB), saving you several hundred dollars. Booking directly on the app makes it easier than heading to each airline’s page and booking separate tickets. This app is free to download.

Farecompare gets its data from a company called ATPCO, which processes fares from the airline computer systems and delivers them to travel agencies and what are known in the industry as Global Distribution Systems (GDS's) such as Sabre, Galileo, and Apollo. Domestic fares are updated by ATPCO (and thus by Farecompare) three times a day during the week and once a day on weekends.

In addition to setting alerts for all the trips you know you want to take, travelers should be prepared to book spontaneous flights, too. Like the DealRay app, Thrifty Traveler and Scott’s Cheap Flights are subscription services that will notify you when there’s a serious deal worth booking — even if the destination hadn’t been on your radar at all. Instead of a push notification, however, they send e-mail blasts to subscribers.

Having a hip chipmunk find the best airfare may initially seem weird, but the Hipmunk app makes things super clear, with user-friendly charts that map your journey by price, time of day, airline, length of layover and even whether or not your aircraft has Wi-Fi. The app will also track flight prices and provide notifications when the best time to buy is. The “discover” feature offers deals on destinations like Canada or Mexico, and also offers inspiration like “beaches” or “outdoor.” Once you’ve booked a flight you can also reserve a hotel, too. This app is free to download.

With your chosen route selected, look to the left of your screen. You should see a button with a bell icon that says “get price alerts”. This is what you want to click. If you are already signed in, you are good to go. If not, it will ask you for your email. Enter your email address then click ‘Create Alert’. You will now be notified of any price changes for this route.
