Boeing's customer codes used to identify specific options and livery specified by customers was started with the 707, and has been maintained through all Boeing's models. In essence the same system as used on the earlier Boeing 377, the code consisted of two digits affixed to the model number to identify the specific aircraft version. For example, Pan Am was assigned code "21". Thus, a 707-320B sold to Pan Am had the model number 707-321B. The number remained constant as further aircraft were purchased; thus, when Pan Am purchased the 747-100, it had the model number 747-121.

In the 1980s, the USAF acquired around 250 used 707s to provide replacement turbofan engines for the KC-135E Stratotanker program.<ref>Baker, MSgt Burke.

The 707 is no longer operated by commercial airlines. American actor [[John Travolta]] owned an ex-Qantas 707-138B, with the registration ''N707JT.'' In May 2017, he donated the plane to the [[Historical Aircraft Restoration Society]] near [[Wollongong]], Australia.<ref>{{Cite news |last=Huntsdale |first=Justin |date=November 3, 2019 |title=John Travolta visits aircraft museum and soon to be home of his luxury Boeing 707 ahead of its arrival |url=https://www.abc.net.au/news/2019-11-04/travolta-visits-museum-soon-to-be-home-of-his-luxury-boeing-707/11669174 |work=[[ABC News (Australia)|ABC News]] |accessdate=November 17, 2023}}</ref> The plane is planned to be flown to [[Shellharbour Airport]], where HARS is based, once repairs to ensure safe flying condition have been completed.
