Like other Bombardier Aerospace products, it has one the luxurious interior. The Global Express was the business jet with the largest cabin, until being surpassed by the later Gulfstream G650. It can accommodate 12 to 16 passengers in three cabin sections: mostly a forward four-chair club section, a central four-seat conference grouping, and an aft three-place divan facing two chairs. Most have a forward galley, crew rest chair, and crew lavatory. The 10.3-psi cabin pressurization maintains a 4,500-ft. cabin altitude up to FL 450 and 5,680 ft. at the FL 510 ceiling.
