Bombardier Global 5500 vs Gulfstream G280 vs Gulfstream G400 vs Gulfstream G500

All four are large-cabin business jets, but they split into two broad tiers. The Gulfstream G280 is a super-midsize jet, typically offering the shortest range of the group (about 3,600 nm) and seating commonly around 8–10 passengers in a standard executive layout, with higher-density configurations possible. The Bombardier Global 5500 and Gulfstream G400 sit in the long-range large-cabin class: the Global 5500 is typically quoted around 5,900 nm range and usually accommodates about 12–16 passengers, while the G400 is generally positioned near the 4,200 nm range class with similar typical seating in the low-teens depending on layout. The Gulfstream G500 is the step-up long-range large-cabin option, with range commonly around 5,300 nm and typical passenger capacity roughly 12–16. In short, G280 emphasizes efficiency and midsize missions; G400 targets longer missions than a super-midsize; Global 5500 and G500 are the longest-legged, higher-comfort choices for true intercontinental-style flying.
