Largest Commercial Aircraft by Passenger Capacity
The Airbus A380 remains the largest commercial aircraft ever built, with a typical two-class capacity of 575 passengers and a maximum certified capacity of 853 seats. Its upper deck and full-length double-deck design set the benchmark for widebody capacity. The A380 first entered service with Singapore Airlines in 2007 and has been operated by carriers such as Emirates, British Airways, and Qantas according to Forbes. Boeing's 777X family, including the 777-9, offers a more flexible ultra-long-range alternative with seating for over 400 passengers in two-class configuration.
Airbus ended A380 production in 2021 after delivering 251 aircraft, shifting focus to the A350 and A321neo families for high-capacity routes. The A350-900ULR, used by Singapore Airlines on ultra-long-haul routes, can seat around 325 passengers while flying up to 9,700 nautical miles. Boeing's 777-8 and 777-9 are expected to enter service with Qatar Airways and Lufthansa respectively, targeting capacities above 400 seats in dense layouts per Boeing specifications. The current max planes in scheduled service are therefore defined by a mix of the A380, A350-900ULR, and 777-9.
Largest Private Jets and Max Planes in Executive Aviation
Airbus ACJ380 and Boeing BBJ 777X
The Airbus ACJ380 is the largest private jet ever built, offering up to 50 passengers in a full-length double-deck configuration with a dedicated master suite, lounge, and dining area. Its cabin volume exceeds 6,000 cubic feet, making it the largest cabin of any business aircraft. The ACJ380 is based on the A380-800 airframe and can fly up to 8,000 nautical miles at a cruising altitude of 43,000 feet as stated by Airbus.
Boeing's BBJ 777X family, including the BBJ 777-8 and BBJ 777-9, provides a more compact but still ultra-large cabin for VIP and government operators. The BBJ 777-9 offers a cabin volume of over 5,000 cubic feet and a range of up to 7,285 nautical miles, making it the largest purpose-built business jet from Boeing. Gulfstream's G700, while smaller in cabin volume, competes on speed with Mach 0.925 cruise and a range of 7,500 nautical miles per Gulfstream's official data. For ultra-high-net-worth buyers, the max planes in private aviation are currently the ACJ380 and BBJ 777X.
