The McDonnell Douglas MD-87 represents a focused evolution of the successful DC-9 family, designed for high-frequency short to medium-haul routes. This variant emphasizes efficient operations at thinner airports with improved range while maintaining the rugged reliability that defined the Douglas legacy.
As a member of the MD-80 series, the -87 balances passenger capacity, runway accessibility, and fuel economics for network carriers and low-cost operators alike.

Design and Operational Highlights
The MD-87 is tailored for performance on restrictive runways and thin high-altitude airports. A shorter fuselage compared to the MD-83 reduces turnaround times while easing gate constraints at regional terminals. The design preserves the familiar twin-engine efficiency of the DC-9 lineage with modern avionics upgrades.
A key operational advantage lies in higher-density seating flexibility, making the type attractive for hub feeders and point-to-point low-cost carriers. Operators benefit from common type rating with other MD-80 variants, lowering training costs and simplifying fleet management.
Performance Specifications and Range
Under the performance specifications, the MD-87 delivers a balanced capability for short-haul mainline economics. Operators often deploy it on routes of 2 to 3 hours, where its range and payload combination is optimized. The configuration supports direct operations between secondary cities without refueling, reducing sector times and improving slot efficiency.
Payload-range flexibility allows carriers to adjust seating and cargo mix according to route demand, enhancing revenue management. CFM56-3 engines provide a favorable thrust-to-weight ratio, supporting operations from elevated and hot airports where longer takeoff runs are typical.
Aircraft Configuration and Interior Layout
The interior layout of the MD-87 is shaped by its compact fuselage, which influences seat pitch and overhead bin space. Typical two-class arrangements pair a high-density economy section with a smaller premium cabin near the front. The single-aisle configuration drives efficient boarding and deplaning, which is critical for high-frequency operations.
Cabin height and window positioning maintain passenger comfort despite the shorter overall length. Carriers often favor 2-2 seating in economy to maximize capacity while preserving acceptable comfort levels on thin routes.
Maintenance, Reliability, and Operational Considerations
The MD-87 benefits from a mature maintenance ecosystem supported by comprehensive service bulletins and widespread parts availability. Scheduled checks are aligned with operator flight cycles, enabling predictable maintenance planning. The reliability record of the DC-9 family translates into strong dispatch reliability for the MD-87 variant.
Fuel efficiency on this variant reflects careful optimizations around lightweight structures and advanced wing designs. Operators appreciate the forgiving flight characteristics, which reduce training transition time and support mixed fleet operations with other MD-80 models.
