Seating charts for Airbus A380s exist online at SeatGuru, as of April 2015. Different airlines use custom A380s to better fit their needs; for instance, some A380s have a larger first-class seating section. Airlines based in the United States rarely use A380s, which are in greater use worldwide.
All Airbus A380s contain at least 300 economy seats, fewer business seats and even fewer first-class seats. The aircraft has around 14 bathrooms and as many or more galleys. Some airlines have A380s with the first-class section on the lower deck. Several of the airlines have seating arrangements with bassinets.
Air France's A380 contains a fourth seating section, premium economy, which has slightly larger seats than economy. The aircraft has 389 economy seats, most of which are on the lower deck; 38 premium economy seats on the upper deck; 80 business seats, which are angled and considerably larger than economy seats; and nine first-class seats, which are almost three times the size of economy seats.
Emirates uses A380s targeted toward business and first-class travelers. The entire upper deck is devoted to these sections, and some of the business sections come with beds. The first-class seats are closed rooms that also have beds. Emirates has two versions of its A380, with the only difference being the number of economy seats.
