M&N Aviation (United States of America) (JNH, Denver Centennial) has removed the last Learjet 60 from its Part 135-certified fleet, ch-aviation research reveals. The 21.2-year-old aircraft, N618L (msn 60-267), was effectively retired in mid-2024.

Configured for up to eight passengers, the jet had been operated by M&N Aviation since 2020 and was based at Teterboro at the beginning of 2024. In June, it was briefly based at Van Nuys before flying to Denver Centennial on July 7, where it remained parked until December 28. It then performed a test flight, continuing to Syracuse Hancock International the following day.

Now, the aircraft has been added to the Part 135 certificate of Altius Aviation and commenced operations under the company's 'STY' code with a test flight on February 8, 2025. Since then, it has been based at Syracuse Hancock International. It joins another Learjet 60 and a Learjet 60XR in Altius Aviation's charter fleet, alongside two Learjet 45XRs and a Citation Sovereign.

M&N Aviation previously operated another Learjet 60 between 2019 and 2022 and a Learjet 60XR between 2019 and 2021. The company's Part 135 fleet now comprises three Challenger 300s, a BAe-125-800A, eight Hawker 800XPs, a Hawker 800XPi, a PC-12, and a Premier I.
