Wanderlust is a funny thing. When it strikes, the urge to go is powerful, but it may not send you in a particular direction. It can turn the simple question—where?—into an agonizing choice. But, like most things in life, there's a website for that: Concorde.io is an airfare aggregator, new in February, that lists flight deals that you can book right now, pulled from around the internet. At first glance, it's a wholesale list of amazing flights—$131 round-trippers in the U.S. on United, or flights to Cape Town, South Africa for $700. You don't even need to know your dates. Travelers with tons of flexibility or chronic indecision, rejoice.

Here's how it works: Head to the site's "Deals" tab, and start browsing. From there, you can narrow your options by choosing a departure month. October? Sure, why not. Users can also set up an account and sign in to the "Discover" section (new this month) to customize their profile, which will let them choose departure dates and airports, and sort options by cost-per-mile.

There's no charge to search or book through Concorde, but the site does receive commissions from bookings—"typically $5-$10 depending on if the flights are domestic or international," John Marbach, Concorde's founder, tells Condé Nast Traveler. Concorde has posted deals from Baltimore, Boston, Los Angeles, and Washington, D.C., but primarily publishes for New York and San Francisco. (Marbach says he plans to publish more deals in other metro areas based on demand.)

Most deals on Concorde are from New York or the Bay Area, though Marbach says he plans to publish more deals in other metro areas based on demand.

For more insight into Concorde, we asked Marbach a few questions:

Who is Concorde made for?

I built this tool for people who are impulse flyers with flexible schedules. As one user recently put it, I am building a tool for the person who "...[wants to] know if I could suddenly get to Poland for $350." Typically this type of person is a young professional with some disposable income, or a college student, and wants to explore the world without breaking the bank before they even arrive at their destination.

There are so many other flight deal sites—it's a crowded space. How does Concorde stand out?

There is a lot of competition, for sure, but there are also a lot of flyers who seek this type of information. Concorde is primarily focused on building tools for its users to discover deals themselves. While we publish compelling deals for the benefit of our users, we are focused on empowering users to be able to easily discover cheap flights from their own home airport, wherever that may be.
