To Understand Where These Jets Land, Understand How They Were Bought

When a Challenger 3500 or a Praetor 600 appears on the ramp at Juan Santamaría (MROC) or Daniel Oduber (MRLB), most ground handlers see an aircraft. The operators who own that aircraft see something else entirely: a financial instrument, sized and scheduled years in advance, that has to generate utilization to justify its place in the fleet. The reason NetJets and Flexjet behave the way they do on the ground in Costa Rica is inseparable from how they acquire and deploy their fleets in the first place. The buying behavior on the ramp is the downstream consequence of a fleet acquisition strategy decided in Columbus and Cleveland long before the trip was ever booked.

The Fractional Model Is a Utilization Machine

A fractional operator does not sell jets. It sells fractions of jets typically in 1/16th increments, each share corresponding to roughly fifty guaranteed flight hours a year — and then runs the entire fleet as a single pooled resource. You buy a fraction of a plane, usually starting at 1/16th ownership, which translates to roughly 50 hours of flying per year, and you share fleet access with other owners located all over the world. The crucial detail for anyone handling these aircraft is the consequence of that pooling: despite buying into a specific aircraft, most fractional ownership programs will not provide the same jet every time. The tail number that lands in Liberia is not "the owner's airplane." It is whichever airframe in the pool was most efficient to position for that leg. The entire model is an exercise in maximizing utilization across hundreds of aircraft, which is why these operators think in terms of network flow, repositioning cost, and crew duty cycles not individual trips.

The Workhorse Is Chosen Before the Trip Exists

The aircraft you see most often from these operators is not an accident of who happened to book. It is the deliberate center of gravity of a multi-billion-dollar order. As of May 2026, NetJets operated a fleet of 858 aircraft, and the backbone of that fleet is built on a small number of high-utilization types. NetJets has placed orders and options for nearly 2,000 new private jets from Textron Aviation, Embraer, and Bombardier the scale of which only makes sense if a handful of models are being flown extremely hard. In the light category, the workhorse is singular: NetJets operates only one aircraft type in the light business jet category, the Embraer Phenom 300. Flexjet built its identity around a parallel bet, becoming the first and only fractional provider to operate the Embraer Praetor 500 and 600, and in 2025 doubled down with a purchase agreement valued at up to USD $7 billion, including a firm order of 182 aircraft and 30 options, that will nearly double Flexjet's fleet size over the next five years. When an operator commits billions to a single airframe family, that airframe becomes the aircraft that shows up on your ramp repeatedly, predictably, across an entire season

Two Operators, Two Philosophies, Two Ground Footprints

NetJets and Flexjet reach the same business through opposite doors, and the difference is visible on the ground. NetJets runs on scale and availability a fleet built for guaranteed lift, backed by Berkshire Hathaway, sized to absorb peak-day demand that smaller programs cannot. Flexjet positions itself as the boutique alternative, competing on aircraft newness and cabin consistency: its Red Label program assigns flight crews dedicated to a single aircraft, paired with a notably newer average fleet age than its larger rival. For a ground handler, this matters more than it appears. The NetJets philosophy demands a handler who can absorb volume and never become the bottleneck during a high-season surge. The Flexjet philosophy demands a handler whose service standard matches a brand built on consistency and a dedicated-crew promise. Both are flying broadly similar super-midsize metal — the Challenger 3500 sits at the heart of both fleets but the operating expectation attached to that metal is shaped by how each company sells the experience upstream.

Why This Reaches All the Way Down to a Ramp in Costa Rica

The financial structure explains the operational behavior. Because a fractional aircraft is a depreciating asset that owners have paid to access on guaranteed terms, the operator's entire incentive is to keep airframes moving and avoid anything that idles a jet or breaks the service promise. The asset depreciates 30 to 50 percent over five years, the management fee is paid every month whether or not the owner flies, and availability is guaranteed contractually which means a delayed turn, an unavailable fuel uplift, or a missed slot in Liberia isn't a minor inconvenience. It's a breach of the core promise the owner paid a premium for, and it propagates back through the entire pooled network. That is the real reason these operators vet handlers so rigorously and return only to fields that behave predictably. They are not protecting a single trip. They are protecting the utilization economics of an 800-aircraft machine, and every field they touch MROC, MRLB, MRLM, MRPV is either an asset to that machine or a liability to be routed around.

The Takeaway for Ground Handlers

If you want to win and keep fractional fleet traffic, stop thinking about the passenger and start thinking about the fleet's economics. These operators buy a small number of workhorse types in enormous quantities, fly them at maximum utilization across a pooled network, and sell guaranteed access on top of that machine. The handler that earns their loyalty is the one that protects the utilization promise — reliable turns, guaranteed fuel and ramp space through the high season, and a single accountable point of contact for the full trip-support chain across overflight permits, CENAMER routing, and customs. The aircraft on your ramp was chosen years ago in a boardroom. Whether it comes back is decided every time it lands.
