The Boeing 767 entered service with United Airlines on September 8, 1982, with the 767-200. A decade later, the airline would also take delivery of its first 767-300, N641UA. After its merger with Continental Airlines in 2010, the combined airline also became one of the two operators of the 767-400.

All of United's originally ordered 767-300s, save for 3, are still actively flying with the airline to this day; that could change soon, however, as the fleet's average age is approaching 3 decades old. United is currently scheduled to phase out its 767 fleet by the 2030s.

Delivered on January 20, 1993, N656UA (fleet number 6456) is among the oldest in the fleet. Ship 6456 has been with United through thick and thin, and has worn a total of 5 liveries throughout its long career: Saul Bass, Battleship Gray, Rising Blue, Continental Globe, and Evo Blue. The version of ship 6456 depicted in the build is sometime between 2010, when Continental-United merger, and 2018, when she got her winglets.

Credit for the original 767-300 and the livery goes to BaconEggs! Seeing that she already made a Continental variant (albeit on a 767-400), I couldn't help myself.
