The 747, which entered service in 1969, served as the backbone of intercontinental air transportation from the 1970s to the early 2000s, with its carrying capacity of about 400 passengers. From its introduction, it was the largest commercial airplane, a position it held until 2008 when the 555 passengers A380 was introduced. Several versions of the airplane were produced, including for air cargo operations (747-400F). The 747 remains one of the most significant aircraft supporting the advent of affordable air transportation. By the second decade of the 21st century, 747s started to be removed from commercial passenger services for more energy-efficient aircraft. It is expected that by 2025, the majority of the fleet will be retired.
