This travel app helps you take advantage of flash airfare deals

When you're planning a vacation, think about things from the airline's point of view. Jet fuel is expensive. Airplane maintenance is expensive. Ergo, empty seats equal a lot of lost revenue.

There are a few travel sites out there that can turn someone else's canceled flight into your gain, but you'd be hard-pressed to find one that does it better than Matt's Flights.

If you're flexible on your travel plans, a subscription to Matt's Flights can really pay off. Just enter your location and your ideal destination, and let the algorithms go to work. As soon as they find discounted rates, either through airline mishaps or last-minute deals, they'll pass them on to you.

Once your deal is locked in, subscribers get personal support to flesh out the whole trip. You can expect to get three or more deals sent your way every week, so when the time is right, you can get your ideal vacation for a fraction of the price.

Take your pick of subscription plans to Matt's Flights, all of which are on deep discount. Grab a one-year plan for $25, three years for $79, or a lifetime for $199. And you can take an extra 15% off the final price of any plan by entering the early Black Friday code BFSAVE15 at checkout, lowering the final prices to $21.25, $67.15, and $169.15 respectively.
