Comparison between Boeing 747-8i and Airbus A380

The Boeing 747-8 represents the final iteration of the renowned Boeing 747 family, serving as Boeing Commercial Airplanes’ largest aircraft. Following the introduction of the 747-400, Boeing explored larger variants as potential competitors to the proposed double-deck Airbus A3XX, later developed into the Airbus A380.

Conversely, the Airbus A380 stands as a colossal wide-body airliner developed and manufactured by Airbus. It holds the distinction of being the world’s largest passenger airliner, featuring a full-length double-deck design. Airbus initiated studies for the A380 in 1988, formally announcing the project in 1990 to challenge the Boeing 747’s dominance in the long-haul market.
