Air Charter Scotland (EDC, Perth Scone) has retired its last Citation Jet 1, as revealed by ch-aviation research. Since 2006, the UK-based charter operator managed three Citation Jet 1s, retiring the first in 2010 and the second in 2011. After briefly reintroducing the type in 2021, Air Charter Scotland has now phased out the model entirely.

G-COBN (msn 525-0429) completed its last flight under Air Charter Scotland's 'EDC' code on October 12, 2024, from Cannes Mandelieu to Oxford Kidlington. The six-seater jet, now listed for sale with EliottJets, subsequently flew to Minneapolis Flying Cloud under its new US registration, N429EA, making stops at Wick, Reykjavik Domestic, Iqaluit, and Duluth International between October 30 and 31, 2024. Originally delivered and registered in the US, the 23.5-year-old aircraft operated under a Spanish registration with Gestair Private Jets (GES, Madrid Barajas) between 2004 and 2014. It was then registered in the UK, where it held two different registrations before joining Air Charter Scotland in 2021.

Air Charter Scotland specialises in private jet services, including charter flights, aircraft management, maintenance, and acquisition and sales. Following the retirement of its final Citation Jet 1, the company's fleet now comprises eight aircraft, including two Citation Jet 2s, one Citation Latitude, one Dassault Aviation Falcon 7X, one Legacy 500, one Legacy 600, and one Praetor 600. The company also recently added an Embraer EMB-135ER, which entered service at the end of September 2024, operating on behalf of Travelcoup (Zurich).

Additionally, Air Charter Scotland holds a 49% stake in Air Charter Scotland Europe (SCO, Malta International), with the remaining 51% owned by a Dutch national, Elisabeth Hendrika McFarlane. The Maltese subsidiary operates two Bombardier Business Aircraft Challenger 350s, one Citation Jet 2+, and three Citation Excel jets.
