N837SY

This airframe, registered as N837SY, is a Boeing-built narrowbody designated Boeing 737-8KN with manufacturer listed as Boeing and construction year 2012. The manufacturer's serial number for the airframe is 40252. The aircraft is recorded as owned by the corporation SUN COUNTRY INC, based in Minneapolis, MN, US, and carries a US registration. Registry reports indicate a high-density single-class configuration of approximately 191 seats. Valuation and detailed condition reports are Not published.

The aircraft is fitted in a high-density single-class layout consistent with the registry notation of 191 seats, reflecting a configuration optimized for short- to medium-haul, high-utilization operations. Avionics fit and specific cabin amenity lists are Not published; however, the airframe’s seating density and operator profile indicate a focus on economy-class passenger throughput rather than premium cabin services. Based in Minneapolis with SUN COUNTRY INC as owner-operator, typical mission profiles for this airframe would use its 2,935 nm range and cruise of 453 kts on domestic and near-international routes within North America and adjacent markets. Routine maintenance considerations are driven by the ubiquitous CFM56-7B powerplants and standard airframe checks for a 2012-build 737-family aircraft.

As a member of the 737 Next Generation family lineage, the Boeing 737-8KN occupies the performance niche for single-aisle, medium-capacity trunk routes where high seat counts and frequent rotations are prioritized. Competing models in the same mission segment include the Airbus A320 family variants, which offer similar range and capacity options. Buyer and charter demand for a 2012-built, high-density 191-seat 737 tends to favor low-cost carriers and leisure operators seeking high seat-mile economics. Maintenance and resale considerations for this airframe reflect its 2012 vintage, common CFM56-7B engines, and a configuration that may require interior rework for operators seeking lower-density or premium layouts.
