Bombardier Challenger 3500 vs Bombardier Challenger 650 vs Cessna Citation Cj4 vs Cessna Citation Longitude vs Embraer Praetor 600 vs Gulfstream G280 vs Gulfstream G600

The Cessna Citation CJ4 is the light-jet option in this group, typically seating about 7–10 and suited to shorter missions, with roughly 2,000+ nm range. The Bombardier Challenger 3500, Embraer Praetor 600, Gulfstream G280, and Cessna Citation Longitude sit in the super‑midsize class, generally carrying around 8–12 passengers with transcontinental capability; typical published ranges cluster from about 3,400 nm (Challenger 3500) through roughly 3,500–3,700 nm (Longitude and G280) up to about 4,000+ nm (Praetor 600). The Bombardier Challenger 650 is a large‑cabin jet, commonly configured around 10–12 passengers, offering more cabin volume than the super‑mids but similar headline range in the ~4,000 nm class. The Gulfstream G600 is the long‑range large‑cabin step up, usually seating about 13–19 and designed for significantly longer missions, with published range around 6,500+ nm, making it the clear intercontinental performer among these aircraft.
