N953JM

This airframe, registered as N953JM, is a Boeing-built 747-438 completed in 1991 with manufacturer serial number 25151. It is owned by ALTA AIRLINES HOLDINGS LLC, an LLC based in Salt Lake City, Utah, United States, which appears on current registry records as the registered proprietor and operator base. The airframe retains its original Boeing identity and US registration while having a documented service history that includes a historic Qantas service configuration and subsequent withdrawal prior to its current high-capacity certification. Condition notes and valuation specifics are not published in the supplied data.

The airframe is certificated in an FAA-approved high-capacity passenger arrangement listing 550 seats, though its operational history included a lower, three-class layout of approximately 364 seats during Qantas service before withdrawal from that service. Avionics specifics are not provided in the dataset; the 747-400 series platform typically supports long-range ETOPS-capable navigation and complex communications suites consistent with international passenger operations. Typical mission profiles for this aircraft align with long-haul, high-capacity trunk routes and charter operations where the combination of range (7,260 nm) and cruise speed (495 kts) are leveraged. Maintenance considerations reflect its four-engine RB211 powerplant architecture and the logistics of operating a large, in-service 747 in a US-registered operator environment.

The Boeing 747-438 sits within the 747-400 family as a long-range, high-capacity widebody that historically competed with very-large-body types for intercontinental trunk routes. Its four RB211 engines and high seat count place it in a niche for high-density long-haul or ferry and military-transport-type charters rather than contemporary point-to-point twinjet service. Market demand for such airframes is specialized; resale and maintenance considerations emphasize airframe hours, heavy maintenance status, and the cost/availability of RB211 engine support and spares.
