the largest passenger aircraft in use is the airbus A380. and we flew it. from new york to france.

the above photo was taken at Paris Charles Du Galle airport.

from wikipedia :

The A380’s upper deck extends along the entire length of the fuselage, and its width is equivalent to that of a widebody aircraft. This allows for a cabin with 50% more floor space than the next-largest airliner, the Boeing 747-400, and provides seating for 525 people in a typical three-class configuration or up to 853 people in all-economy class configurations. The postponed freighter version, the A380-800F, is offered as one of the largest freight aircraft, with a payload capacity exceeded only by the Antonov An-225.[3] The A380-800 has a design range of 15,200 km (8,200 nmi), sufficient to fly from New York to Hong Kong for example, and a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude).

here is a view of the plane from the tail camera, as seen on my in-flight tv monitor.

i sat right over the wing on the lower level. it was huge! and i didn’t hear any excessively loud engine noise from those massive Rolls-Royce engines.
