Boeing-Mcdonnell Douglas Boeing (Douglas) Md 88

Twin Jet· 72 globally registered

The McDonnell Douglas MD-88 represents the final evolution of the DC-9 family, a lineage that began in the 1960s and became one of the most successful narrow-body jet programs in aviation history. Introduced in 1987, the MD-88 was essentially an MD-80 series aircraft upgraded with an Electronic Flight Instrument System (EFIS) glass cockpit, improved avionics, and a windshear detection system, modernizations that kept the venerable rear-engine, T-tail design competitive into the 21st century. Powered by two Pratt & Whitney JT8D-217C turbofans mounted on the aft fuselage, the MD-88 could carry 142 to 172 passengers across ranges up to 2,050 nautical miles, making it ideal for domestic trunk routes. Delta Air Lines became the type's dominant operator, flying MD-88s for over three decades until their retirement in 2020. The aircraft's distinctive howl from its low-bypass engines and its ability to operate from shorter runways made it a workhorse on routes throughout the southeastern United States. While the MD-88 never achieved the global ubiquity of Boeing's 737 or Airbus's A320, it carved out a loyal niche among carriers who valued its hot-and-high performance and relatively simple systems. The type's retirement marked the end of an era for the DC-9 family, which had accumulated over 2,400 aircraft built across all variants since 1965. Today, the MD-88 survives primarily in charter and cargo operations, with a handful of airframes still flying for specialized carriers. The type's operating envelope includes a maximum operating speed of 365 knots IAS or Mach 0.84, a service ceiling of 37,000 feet, and approach speeds around 138 knots. These performance figures remain respectable by modern standards. SkyMeter has tracked 42 flights across 9 airframes and 3 operators, with USA JET AIRLINES INC the largest observed operator.
