Bombardier Challenger 650 vs Bombardier Global 6500 vs Gulfstream G650er

The Bombardier Challenger 650 is a large-cabin business jet aimed at regional and transcontinental missions, typically offering seating for about 8–12 passengers (with higher-density layouts possible). Its range is roughly 4,000 nautical miles, making it well suited for routes such as New York–London in favorable conditions, but it is not in the ultra-long-range class. The Bombardier Global 6500 moves into the ultra-long-range, large-cabin category with a bigger cabin and higher typical seating, often around 12–16 passengers. Its range is about 6,600 nautical miles, enabling frequent nonstop city pairs like Los Angeles–London or New York–Dubai depending on winds and payload. The Gulfstream G650ER is an ultra-long-range flagship with a similarly spacious large cabin and typical seating around 14–17 passengers. With approximately 7,500 nautical miles of range, it generally leads this group for nonstop capability, supporting longer pairings such as New York–Hong Kong or Los Angeles–Sydney under the right operating conditions.
