The sun has set on United's 747 operations

United today ended 747-400 service, with a final revenue passenger flight from San Francisco to Honolulu.

Like most US Majors in the early 1970s, it was a must have to acquire 747-100s as an airline's flagship aircraft, typically used on premium coast to coast domestic service (United, American & Delta), with Pan Am, TWA and Northwest operating the type on key transatlantic and transpacific routes.

Many also went on to acquire new or used 747-200s, as well as 747-SPs, the latter acquired by United when it took over Pan Am's transpacific routes. No 747-300s were ever ordered or operated by US airlines.

The aircraft proved too large though, with most phased out of domestic service by the mid-70s, and replaced by tri-jet DC-10s and L-1011s (which were also too large initially). Braniff alone stuck with narrow bodies for domestic routes, which turned out to be strategically the correct decision at the time.

The second generation, and most important 747 of the last two decades was the 747-400, ordered in significant quantities by United and Northwest.

N171UA was the first -400 delivered to United, seen above in original delivery colors, the first of four liveries this aircraft would carry during it's 26 year career.

United took delivery of 44 747-400s, the final delivery being in May 2000. All were model 747-422s, with the exception of two 747-451s, built for Northwest, but sold new to United.

This livery was relatively short lived, as following the 2011 merger with Continental, the latter's color scheme was selected for the 'new' United.

The post 9/11 world saw United make adjustments to it's fleet, and the 747-400 did not escape a reduction. By 2015, 31 were in service, 25 by 2010, and 22 by 2015. N171UA was retired in October 2015.
