Something is happening in the middle of the private aviation market that has not received the attention it deserves from the principals operating at the top of it.
The midsize jet segment — the Cessna Citations, the Hawker 800s, the older Learjet 60s that formed the operational backbone of the European and North American charter market for two decades — is shrinking. Not gradually. Rapidly. The economics of operating ageing midsize aircraft have deteriorated past the point of viability for a growing number of smaller operators, and the replacement cycle — acquiring newer midsize aircraft to maintain the segment — is not happening at the pace required to fill the gap.
The reasons are structural and compounding.
Maintenance costs on older midsize aircraft have risen sharply as parts availability tightens and the engineer pool qualified to work on legacy platforms shrinks. Fuel costs, elevated since 2022, hit the less fuel-efficient older platforms disproportionately. The pilot shortage — which is real, severe, and worse than the industry’s public communications acknowledge — has driven crew costs up across the board, but the smaller operators who predominantly run midsize aircraft have fewer resources to absorb the increase and less negotiating leverage in the crew market.
Why the principals at the top should care
The midsize tier serves a routing and commercial function that is not replicated by larger aircraft. Short domestic sectors where a heavy jet is operationally excessive. Positioning flights where the economics of moving a Global 7500 across a continent to pick up a single passenger begin to strain even the most well-resourced aviation programme. Supplemental lift for secondary travellers — family members, staff, accompanying teams — when the principal’s primary aircraft is otherwise committed.
As the midsize tier contracts, the operators who remain in it are carrying higher costs, managing older fleets with greater maintenance uncertainty, and operating in a market where the supply-demand balance has shifted in ways that are not uniformly visible in charter rate quotes.
The principal whose aviation programme has an implicit dependency on midsize supplemental lift — who has never examined that dependency explicitly because it has always been available when needed — is carrying a programme risk that the contraction of this segment is making progressively more material.
What is replacing it
Two things are happening at the edges of the gap the midsize contraction is creating.
At the lower end, very light jets — the Pilatus PC-24, the HondaJet Elite, the newer Embraer Phenom variants — are taking some of the short-sector, lower-cost routing that the midsize segment previously served. They are not direct replacements. Their range and cabin capacity limitations mean they solve some of the use cases and none of others.
At the upper end, the super-midsize segment — the Gulfstream G280, the Bombardier Challenger 350, the Embraer Praetor 600 — is absorbing the demand from clients who were previously flying midsize and have concluded that the additional cost of a better aircraft is preferable to the operational uncertainty of the segment below.
This upward migration is real and it is one of the demand drivers behind the super-midsize order backlogs that have extended delivery timelines at every major manufacturer.
The market is not simply losing a tier. It is redistributing its demand. The principals whose aviation programmes account for this redistribution explicitly — who have examined their midsize dependency and made conscious decisions about how to replace it — are operating with a clarity that the programmes which have not done this work do not yet have.
The time to examine the dependency is before the aircraft is not there.
