The Origin of 787 vs 777
777 History
The Boeing 777 first flew in the early 1990s. It was created as a replacement for older long‑haul jets like the Boeing 747 on some routes, offering two powerful engines and a wide cabin.
787 Dreamliner History
The 787 Dreamliner came much later, entering service in 2011. Boeing originally named it the 7E7 before renaming it the 787. It was built to be lighter and more efficient, using advanced composite materials instead of mostly aluminum.
