GUNET first flew with Air Canada as a passenger aircraft in 1991 as CGAGN. In 2005 ownership passed to Guggenheim Aviation Partners when the aircraft was converted to Cargo operations.
In 2006 the aircraft flew for Air China Cargo until 2014, when it was transferred to ACT airlines (registered as TCACJ) (As the plane passes the camera in this film you can still make out the ACT lettering on the tail). It also saw life briefly with Saudia Arabian Airlines and Aerotrans Cargo (reg. ERBBB) before being transferred to One Air in July 2022 and reregistering as GUNET. One Air is a new British allcargo airline offering full charter services to clients in the international freight forwarding, logistics and air charter markets. One Air started Heathrow 747 operations on the 23rd July 2023, with a twice weekly service to Jinan in China.
