The Boeing B767 is a proven and versatile wide-body aircraft that has been a cornerstone of medium- and long-haul operations for airlines worldwide. Introduced in the early 1980s, this twin-engine jet was one of the first to pioneer extended-range twin-engine operations (ETOPS), allowing for efficient transatlantic and transpacific routes. With seating capacities ranging from 181 to 375 passengers, depending on the configuration and variant, the 767 offers a flexible cabin layout. It is widely used for both passenger transport and cargo operations, with dedicated freighter models serving major logistics carriers. The aircraft features a comfortable cabin with a 2-3-2 seating configuration in economy class, maximizing passenger comfort. Its efficient aerodynamics, combined with engines from General Electric (CF6), Pratt & Whitney (PW4000), or Rolls-Royce (RB211), contribute to reduced fuel consumption and operational efficiency. Airlines favor the Boeing B767 for its reliability, cost-effectiveness, and ability to operate on long-haul routes without the capacity requirements of larger wide-body aircraft like the Boeing B777 or B787.
