The maximum certified carrying capacity is 853 passengers in an all-economy-class layout, Airbus lists the typical three-class layout as accommodating 525 passengers, with 10 first, 76 business, and 439 economy class seats.

The Airbus A380, the world's largest passenger aircraft, has a capacity that varies wildly depending on how an airline chooses to configure its massive double-deck interior. In a standard four-class configuration (First, Business, Premium Economy, and Economy), the A380 typically carries between 480 and 550 passengers. For example, Emirates—the largest operator of the type—often configures its fleet to carry about 517 passengers in three classes. However, the aircraft is certified for a maximum "exit limit" of a staggering 853 passengers in a high-density, all-economy configuration. While no airline currently flies an 853-seat version, some carriers utilize a two-class setup that can carry over 615 people. In 2026, the A380 remains a favorite for "hub-to-hub" long-haul routes because of this sheer volume; its cabin area is roughly equivalent to three tennis courts. Despite its size, the A380 is praised for its quietness and stability, providing a high level of comfort even when flying with over half a thousand other travelers across the world's longest commercial flight paths.
