Bombardier Challenger 3500 vs Cessna Citation Longitude vs Gulfstream G280 vs Gulfstream G400

The Bombardier Challenger 3500 and Gulfstream G280 sit in the super-midsize category, while the Cessna Citation Longitude is typically positioned as a larger super-midsize/“large-cabin light” step-up, and the Gulfstream G400 is a true large-cabin, long-range jet. For range, the Challenger 3500 is roughly in the ~3,400 nautical mile class, the Citation Longitude about ~3,500 nautical miles, and the Gulfstream G280 leads this group of super-midsize jets at about ~3,600 nautical miles. The Gulfstream G400 is in a different league, with an advertised range around ~4,200 nautical miles. In passenger capacity, these aircraft commonly seat about 8–10 passengers in typical layouts for the Challenger 3500 and G280, with the Longitude often configured around 8–12 depending on cabin options. The G400 generally accommodates more, commonly around 10–14 passengers, reflecting its larger cabin and more flexible long-range mission profile.
