United and the Boeing 777: From 1990 to the 777X

United Airlines set commercial aviation on a new path when it launched the Boeing 777 program in 1990, leading up to the aircraft's formal debut in 1995. That rollout established an iconic twin-engine widebody lineage that would dominate long-haul travel for decades.

Now, decades after United's inaugural service, the forthcoming 777X is positioned to reshape the storied program for modern long-distance flying.
