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

All four are super‑midsize business jets aimed at similar missions, but they differ in cabin focus and reach. The Bombardier Challenger 650 is best described as a large‑cabin, long‑running super‑midsize with strong comfort and payload; typical range is about 4,000 nautical miles and it’s commonly configured for around 10–12 passengers (can be arranged higher depending on layout). The Cessna Citation Longitude is a newer‑generation super‑midsize emphasizing operating efficiency and a quiet cabin, with roughly 3,500 nautical miles of range and typical seating around 8–12. The Embraer Praetor 600 is a tech‑forward super‑midsize with one of the strongest ranges in the class at about 4,000+ nautical miles and typical capacity around 8–12. The Gulfstream G280 is a high‑performance super‑midsize leaning toward the upper end of the segment, with about 3,600–3,800 nautical miles of range and typical seating around 8–10 (often up to about 10–12 by configuration).
