Sun-Air (EZ, Billund) retired its sole Challenger 650, which was most recently operated by the group's charter unit, JoinJet, ch-aviation research has revealed.

OY-LLG (msn 6156) was flying under Sun-Air's 'SUS' code until August 27, 2024, when it operated between Billund and Berlin Brandenburg International. On November 4 it was first active under JoinJet's 'JNJ' code, performing a test flight before returning to Billund. The 4.4-year-old Bombardier Business Aircraft, configured to carry up to 12 passengers, remained active with JoinJet's code until December 11, when it completed a final test flight around Billund. It was reregistered in the United States as N585JP on December 23. The jet is not currently listed as Part 135-certified and has yet to operate under the new registration.

Sun-Air operates eleven Do328-300s, with four currently active, alongside a Citation I/SP, a Hawker 800XP(2), and a Hawker 800XP(R). The latter two are configured for air ambulance services under SmuuthCare, an air medical subsidiary of Sun-Air. JoinJet is currently operating five aircraft under the 'JNJ' code, including a recently inducted Challenger 3500, three Hawker 4000s, and a Global 5500, also recently added. Additionally, the company manages a Citation Jet 3+, which does not fly under the same code.
