Yes, the Airbus A330-300 is classified as a "wide-body" or "jumbo" aircraft, making it a "big plane" by commercial aviation standards. It features a "twin-aisle" cabin configuration, typically seating between 250 and 300 passengers in a three-class layout, or up to 440 in a high-density single-class setup. With a length of approximately 63.69 meters (209 feet) and a wingspan of 60.3 meters, it is significantly larger than "narrow-body" planes like the Boeing 737 or Airbus A320. It is designed for medium-to-long-haul intercontinental routes, with a range of up to 11,750 km (6,350 nautical miles). While it is smaller than "super-jumbos" like the Airbus A380 or the Boeing 747, it remains a cornerstone of international travel due to its efficiency and spacious 2-4-2 seating arrangement in economy, which many passengers prefer over the 3-3-3 layout of larger jets.
