615 Emirates

Emirates' Airbus A380s have many different configurations. The most notable layout, for now at least, is its non-first-class, two-class, 615-seater. This Gulf giant has 15 airframes with that capacity. The low-premium layout has 58 seats in business (versus 76 with its other superjumbos) and a whopping 557 seats in economy (compared to 322 to 429 with its other configs).
