N866DN

This airframe, registered N866DN, is a Boeing 737-932ER (737-900ER) built in 2016 with manufacturer serial number 31977. It is owned and operated by Delta Air Lines, a corporation based in Atlanta, GA, US, and carries a United States registration. The airframe is configured in Delta’s three-class mainline layout and has remained within the Delta fleet since delivery, retaining operator registration and standard mainline maintenance tracking in the U.S.. No public record of significant registry transfers or ownership changes beyond its original corporate owner has been published.

The aircraft carries a Delta three-class mainline cabin layout with First / Comfort+ / Main seating in a carrier-configured 180-seat arrangement, reflecting a dense mainline short- to medium-haul configuration optimized for higher-capacity domestic and transcontinental missions. Typical mission profiles leverage the 737-900ER’s extended-range capability of 3,235 nm and cruise speed of 456 kts to serve domestic trunk routes and select longer thin international sectors from Delta’s Atlanta hub. Avionics and systems conform to Boeing Commercial Airplanes standard fit for the 737-900ER family as delivered, and line maintenance follows Delta’s mainline heavy-check schedules consistent with U.S.-registered, high-utilization fleet aircraft. Known maintenance considerations align with the CFM56-7B engine family service bulletins and 737-900ER structural/winglet inspections applicable across the type.

The Boeing 737-900ER is positioned in the single-aisle, high-capacity short-to-medium-range niche, competing with stretched variants of the Airbus A320 family for dense domestic and thin international markets. With dual CFM56-7B engines rated at 27,300 lbf each, the type balances fuel efficiency and proven engine support networks, making it attractive to large network carriers like Delta for high-frequency routes. Buyer and lease demand for late-production, carrier-configured 737-900ERs is typically driven by mainline fleet replacements and schedule density needs; resale and maintenance considerations emphasize remaining structural fatigue life, cabin reconfiguration potential, and ongoing CFM56-7B support.
