N8574Z

This airframe, registered as N8574Z, is a Boeing 737-8H4 (737-800) built in 2018 with manufacturer serial number 63588. It is owned and operated by Southwest Airlines Co., a corporation based in the United States, and is registered in the US registry. The airframe has remained within Southwest's single-carrier fleet since delivery, reflecting no recorded changes of operator in public records. Valuation and detailed condition reports for this specific tail are not published.

The aircraft is configured in Southwest's standard single-class, 175-seat economy layout and used primarily on domestic short- to medium-haul missions consistent with the model's range and cruise profile. As a fleet-standard 737-800 within Southwest, this airframe shares common maintenance programs, spares pools, and crew training flows that simplify operations and reduce out-of-service time. Typical utilization includes high-frequency point-to-point rotations across the carrier's U.S. network where the combination of 175 seats and 3,050 nm range supports dense, short-sector scheduling. Specific avionics fit and retrofit status for this tail are not published.

The Boeing 737-8H4 (737-800) belongs to the Next Generation 737 family, positioned for efficient single-aisle short- to medium-haul air transport with strong seat-mile economics at 175 seats. Competing models in the same mission niche include the Airbus A320 family variants, which vie on commonality and operator preference. At a 2018 manufacture date, this airframe represents a relatively recent example within the used narrowbody market, offering favorable remaining service life and resale prospects compared with older production examples. Maintenance and resale considerations for the type center on CFM56-7B engine lifecycle management and airframe hours/cycle accumulation in dense short-haul service.
