Find out what planes JSX flies, how the Embraer ERJ-135 and ERJ-145 differ, why both have 30 seats, and what semi-private means.
In real-world aviation, JSX flies Embraer ERJ-135 and ERJ-145 regional jets. Both are twin-engine aircraft fitted with 30 passenger seats in JSX service, normally in a 1-2 layout with no middle seats. Despite JSX's “semi-private” branding, these are regional airliners, not small private business jets.
Which Embraer jets are in the JSX fleet?
The JSX operating fleet consists of two closely related members of Embraer's original ERJ regional-jet family.
| Aircraft | How to identify it | Common maximum seating | JSX seating |
|---|---|---|---|
| Embraer ERJ-135 | Shorter fuselage | 37 passengers | 30 passengers |
| Embraer ERJ-145 | Longer fuselage | 50 passengers | 30 passengers |
Both have a narrow 1-2 cabin, rear-mounted engines and a T-tail. They use Rolls-Royce AE 3007-family turbofans, although the exact engine suffix depends on the aircraft variant; our Embraer engine-family explanation provides the relevant powerplant context.
Fleet totals and the balance between ERJ-135s and ERJ-145s can change as individual airframes enter or leave service. JSX can also substitute one model for the other, so a route or booking does not guarantee a particular fuselage length.
Why do both JSX aircraft have only 30 seats?
JSX deliberately limits both models to 30 seats rather than using their normal airline capacities. The reduced-density cabin provides more space, gives passengers a consistent layout across the fleet and matches the seating threshold central to the operating model used for its public-charter service.
The reduction is most obvious in the ERJ-145: airlines commonly operate that model with 50 seats, while JSX removes roughly two rows in every five. The smaller ERJ-135 loses fewer seats, but passengers receive broadly the same cabin product whichever model appears.
Are JSX planes private jets?
JSX aircraft are commercial regional jets, while “semi-private” describes the passenger experience rather than the aircraft category. Seats are sold individually on public-charter flights, but boarding commonly takes place through smaller private-terminal facilities rather than a conventional airline gate.
The ERJ family's integral forward stairs help make that operation practical because the aircraft does not require a jet bridge or separate mobile steps. We explain that equipment in our guide to built-in airstairs on regional aircraft.
Older references to JetSuite can cause confusion because that business used Embraer Phenom business jets. Those smaller aircraft should not be mistaken for the ERJ-135 and ERJ-145 regional jets used for JSX's by-the-seat service.
Can I fly a JSX-style ERJ in a flight simulator?
The ERJ-135 and ERJ-145 are available in several generations of flight simulator, although aircraft depth and livery availability vary by add-on. For the older Microsoft platform, our downloadable ERJ-135/145 package for FS2004 includes both airframe lengths and is useful for comparing their handling and proportions; check the included paints rather than assuming a JSX livery is supplied.
