A heavier commercial jet refers to an aircraft designed to carry a larger number of passengers or more cargo than standard jets. These jets typically have a higher maximum takeoff weight (MTOW), allowing them to operate on longer routes and serve busy airports. Examples include the Boeing 777 and Airbus A380, which are known for their capacity and range. These aircraft are equipped with powerful engines and advanced technology to ensure safety and efficiency. Heavier commercial jets often feature multiple classes of seating, in-flight entertainment, and amenities to enhance passenger comfort during long flights.
