The cabin of this specific 737-800 is in an all-economy, 175-seat airline configuration associated with Southwest, indicating a high-density single-class layout optimized for short- to medium-haul scheduled service. Typical mission profiles for this configuration include high-frequency domestic routes and transcontinental sectors within the aircraft’s 3,060 nm range, operating at a cruise speed near 440 kts and a maximum certified altitude of 41,000 ft. Avionics fit and specific complement of onboard passenger amenities are Not published; maintenance considerations follow the family-standard inspections for twin CFM56-7B-powered 737-800s, with engine-line maintenance driven by the CFM56-7B27E/F time and cycle parameters. Operator base and regular route map are Not published.

The Boeing 737-8H4 (737-800) sits in the single-aisle narrowbody category and competes with contemporary narrowbodies in the 150–190 seat segment, offering a blend of range (approximately 3,060 nm) and commonality for fleet operators. Its two CFM56-7B27E/F engines producing 27,300 lbf each provide established reliability and broad MRO support, factors that sustain steady demand in secondary markets and among lessors. Resale and maintenance considerations for a 2018-series 737-800 include engine shop visit cycles, structural checks tied to cycles and hull-life projections, and the value impact of an all-economy, 175-seat carrier-specific interior when transitioning between operators.
