This Startup is Bringing Auctions to Empty-Leg Flights

Every day, hundreds of private jets crisscross the country with empty cabins. It could be a Gulfstream ferrying back from Aspen with no one onboard, or a Citation returning to base after dropping off a single passenger — the seats are left untouched. Operators call these flights “empty legs,” and for decades they have represented one of business aviation’s strangest inefficiencies.

In recent years, operators began selling seats on these empty legs at a fraction of the original cost. Depending on the company, space would be sold on a per-seat basis or by reserving the entire aircraft at a reduced price. But with every operator using their own methods to publish empty legs and various brokers placing different margins on the same tickets, transparency became an issue for passengers.

A small group of developers and an aviation industry insider got tired of watching this value disappear into thin air, so they built an app to address it.

Enter FlyApp, a Delaware-based startup that enables operators to auction off empty-leg segments to passengers seeking the luxury of private air travel without the hefty price tag.

The Old Way

Before FlyApp, filling an empty leg meant phone calls. It meant broker networks, email blasts, and a patchwork of relationships that depended on who happened to be looking for a flight on a given day. Operators absorbed the loss when a leg went unsold. Travelers who might have jumped at a discounted charter had no visibility into what was available or when. The system worked, barely, for people already inside the industry. Everyone else was locked out.

The team behind FlyApp saw an opportunity hiding inside that inefficiency. If operators could list an empty leg the moment it appeared, and travelers could bid on it in real time, the whole equation would change. Supply meets demand directly. No middleman slows down the process. No flight goes to waste that didn't have to.

Building Something Different

FlyApp started as a grassroots effort, not a venture-backed startup with a splashy launch. The founders built the platform from the ground up, piece by piece, driven by a belief that the private aviation market needed more transparency than it had ever offered.

“Empty legs have always existed, but they’ve never been centralized or truly accessible at scale,” said Joe Carello, Founder & CEO of FlyApp. “We’re creating a direct connection between operators and travelers, both new and familiar with private aviation, while reducing the surprisingly large number of wasted travel opportunities.” 

An auction format made sense from the beginning. It removes the guesswork. Sellers set the terms, buyers compete openly, and the price reflects real demand instead of a broker's estimate.

That transparency extends to how the platform treats its users. Operators list a flight and know exactly what they're getting. Travelers place a bid and know exactly where they stand. There is no hidden negotiation happening in a back channel. The auction is the negotiation.

The Roadmap

The vision behind FlyApp reaches well past a single market or region. The team wants the platform active in every city where private aviation operates, creating a connected marketplace instead of a series of disconnected relationships between operators and brokers. That kind of reach doesn't happen overnight. FlyApp's founders are candid about the fact that this is a long build, one flight and one city at a time.

Carello shared, “In the future, we’d like to expand to all realms of aviation, from private jets to eVTOL’s, all around the world.” 

Why It Matters

The private jet market has grown steadily in recent years, with more first-time flyers exploring charter options and more operators looking for ways to maximize aircraft utilization. Empty legs sit at the intersection of both trends. They are the entry point for travelers priced out of a full charter and the recovery mechanism operators need to offset the cost of flying an aircraft home.

FlyApp is betting that a transparent, real-time auction model turns that into an actual marketplace instead of an operational inefficiency. Each empty leg becomes an opportunity, and FlyApp’s entire platform is built around making sure fewer of those opportunities disappear unclaimed.
