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.

Whenever airlines overbook flights and need folks to give up a seat, that is when you have the most leverage for getting concessions and upgrades from the airline. Most of us have been in airports listening to increasingly urgent announcements looking for volunteers to give up their seat; in that situation, you can go up to the gate, set your conditions and then let the airline decide if it can meet those conditions.
Only once you have confirmed your choice of preferred flights and completed the PFo Sign-up, Vietnam Airlines and Optiontown may choose to move you to those preferred flights. The availability of PFo is dynamic and may vary for different flights or time. For passengers who have connecting flights, kindly choose alternative flights that are suitable with your schedule. Vietnam Airlines will not take responsibility for those who miss connecting flights due to your selection of alternative flights. 
One of the coolest features about Kiwi is that unlike it will look at ALL the cheapest possibilities, even if it means putting you on 2 totally separate flights. Other flight search engines will try to book the entire route on either the same airline or airlines with codeshares. It might not always be the fastest or more convenient, but great for anyone on a budget.
With a few extra functions and a smarter user interface, this combination will be the best flight tracking tool in the market. The ability to track your flights after purchase and be notified if there is a chance of a partial refund has the potential to save a lot of money and adds a layer of value the websites on the list don’t have an answer for.
If your specific fare class qualifies you for an upgrade if a seat becomes available, you may receive offers by email or text to purchase (most often in cash but sometimes for miles) the option to upgrade as flight time approaches and seat availability becomes more clear. These tend to disappear quickly, so if you miss the message, the seat won’t last long.
I use Yahoo to search for fares, but although during the search it allows me to narrow down earliest and latest departure (and/or arrival) times, it doesn’t update the price range available based on that, so I doubt it could do useful alert based on that. (I’ve used Yapta for watching a specific flight I’ve already booked to see if it goes down, but that’s a bit different.)
If your itinerary is botched or implodes for some reason, particularly if it affects only you and no one else (such that the airline is not trying to accommodate lots of folks in the same situation), your case for an upgrade on a subsequent flight becomes more compelling. The airline is not obligated to upgrade you, but if this happens, pleasantly but firmly let the gate agents know that if an upgraded seat is available on your rebooked flight, you would greatly appreciate getting that seat.
Jumping on a fantastic deal via The Points Guy or playing around on Google Flights are obviously our preferred ways to book travel, but you may also be able to get a solid price searching via app. Of course, we’ve all used the tried and trusted Kayak app before, but there are others out there that might get you the best offer or price. Here, the TPG-approved list of the best apps for booking airfare.
If I want to use American miles to book a flight on Air Tahiti Nui — a partner some AA agents aren’t aware of — I’ll look up the flight availability on ExpertFlyer first. Once I find an available seat, I’ll call and ask an American agent for the specific flight and fare class I see on ExpertFlyer. If they cannot locate it, I’ll even use the airline’s two-character IATA code to help the agent find the flight I’m trying to book with miles (if you don’t know this code, see below; it’s included in the ExpertFlyer results).

Here’s where the power of ExpertFlyer comes into play. Let’s say that I wasn’t interested in crossing the Atlantic in economy. Instead of coming back to the site multiple times in the weeks and days leading up to my desired flight, I can actually set up a flight alert by clicking on the exclamation point icon (red arrow in the above screenshot). That would open up a window like this:

This award and upgrade search is an option for both the Basic and Premium memberships, but the Premium subscription really comes in handy here thanks to the ability to search +/- 3 days from your desired date of travel. This allows you to view a week at a time, and you can also search for multiple fare classes. You can customize the display and even specify whether you want the platform to only return nonstop flights.
Travel requires that you keep yourself updated with the latest flights status. Often, you would need to check the flights schedule of the airlines for a particular sector while planning your travel. In the age of internet, you can check the flights status and do the bookings far easily than ever before. Instead of running to the travel agent office or making frequent calls, you can get online with Yatra.com which provides an easy online interface to check out which all airlines are operating flights at what all times in a particular sector. We comprehensively cover more than 550 sectors within India, providing the latest sector-based flights information about the airlines operating in the area.
Working in a polar opposite manner to Skyscanner, Airfare Watchdog allows you to set flight alerts from city-to-city, deals from a departure city, or deals to a destination city. However, you cannot set dates for your flight alerts. Rather than relying solely on computers to do the heavy lifting, the team at Airfare Watchdog have airfare analysts that research fares to ensure they're good deals then send them out to accounts signed up to watch those cities. One benefit is that they can pick up unpublished sales and also fares from airlines like Southwest. Airfare Watchdog is best for setting broad flight alerts that are not date-specific.
You can use your eUpgrade Credits to request an upgrade on any eligible Air Canada, Air Canada Express, and Air Canada Rouge flight which features a Business Class, Premium Economy or Premium Rouge cabin, so long as you have a ticketed reservation. You will also need to ensure that your Aeroplan number is entered as your frequent flyer number on your reservation in order to complete an upgrade.

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).
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.
Hopper’s signature rabbit may seem a bit childish at first, but this bunny knows its stuff. The flexibility feature is especially useful: put in your home city and desired destination and Hopper will map out the entire year for you with color-coded prices. The dates are shown as month-long calendars, with colored boxes telling you when prices fall into certain categories, like less than $300 or +$500. The app-only service also predicts whether or not the price for your chosen dates may drop or not (they monitor up to 15 billion flight prices per day) and allows you to “Watch the Trip” —  a feature where Hopper will send you alerts if the price changes. If you know you need a vacation, but are flexible on your destination or dates, you can also set alerts for the app to tell you when there are destinations deals. This app is free to download.

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.”
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.
Service surcharge levied on a booking or booking change (flight date) in line with Article 5.2.3 of the GCC, as booked via the call centre, at our airport sales desk or through a commercial agent ADD €20 / £18 / CHF 23 / $23 / CZK 514 / SEK 205 / NOK 191 / PLN 86 / HUF 6,381 (per booking, not per person and per journey) €20 / £18 / CHF 23 / $23 / CZK 514 / SEK 205 / NOK 191 / PLN 86 / HUF 6,381 / AED 94 / THB 900 plus difference in current flight price
This is a much debated topic! Our latest Twitter poll revealed that 86% of British travellers don’t know when they should be booking their flights to bag the best deals. By creating Price Alerts, you’ll be able to check the price of your chosen flight, and book when the flight ticket is the lowest. In general, you should be looking to book your flight no later than seven weeks before you want to jet off. However, the exact time frame does differ according to your chosen destination. To get exact timings on when to book the cheapest flights, try our The Best Time To Book tool.
The member fares are typically specially negotiated fares — sometimes called "consolidator" fares — that are offered from time to time to various travel agents. You cannot book fares on Bestfares.com; rather you have to call a toll-free number to complete your purchase. But like Farecompare.com below, Bestfares.com provides a good barometer of where fares are at any given moment, and the fares are updated throughout the day.
Sometimes you might be planning a trip but can’t fully commit to buying the tickets just yet. Price Alerts let you monitor the price history of your chosen flight so you can pounce if the airfares suddenly start to creep up. Or perhaps you want to go away on a specific weekend but the flights are far too expensive. Set a Price Alert and you’ll be sent an email immediately if there’s a price drop. Flight prices change frequently, but Price Alerts mean you won’t be caught on the hop if flight prices skyrocket – and you won’t miss out on a deal if prices plummet.
Upgrade Bid upgrades can only be applied once to the next higher class. Upgrades to Business Class are only available for Premium Economy Class passengers. However, for aircraft or routes without Premium Economy Class, you would be invited to upgrade from Economy Class to Business Class. No further upgrade by cash or miles will be honoured after an Upgrade Bid upgrade has been offered.

When it comes to flight upgrades, the airlines are caught in what is viewed by many to be a real Catch-22. Like any business, the airlines have an obligation to maximize revenue and make money for the company. Part of this revenue is generated from the outright sale of tickets in their Premium cabins - First Class and Business Class. However, they also have an obligation to their best customers, namely the frequent flyer and more specifically the Elite flyer to offer flight upgrades and other incentives. Maintaining, and even growing, the base of frequent flyers of an airline depends almost entirely on the "value" of their frequent flyer programs, especially for Elite members. The value of most programs is often judged by the number of seats an airline allocates for either free or mileage upgrades in the very same Premium cabins they are obligated to sell. Hence the Catch-22.
