The average savings on flights with Dollar Flight Club is $500.

It’s quite a statistic, but it makes sense. Flight prices vary wildly, so if you’re flexible with your travel plans and can be alerted whenever there’s a big price drop, you could be saving 60 to 90 percent on your next trip.

Dollar Flight Club is an app and email subscription service. It alerts its 860,000 members about the cheapest flight deals and helps them book their dream vacation.

The app couldn’t be easier to use. You just set your departure airport and regions you’re interested in visiting. Dollar Price Club then alerts you the second there are great savings to be had.

The premium plan of Dollar Flight Club alerts you to four times more international flight deals than the basic version. There are a whole host of other great travel perks too.

A one-year subscription to the premium plan usually costs $69. It’s a shrewd investment if you even save on one flight, but today you can do better still.

While this deal lasts, you can get the same one-year premium subscription for just $19.99. Pack your bags.

Like a cheap flight deal, this offer will end soon, so hit the button below to sign up.
