Middle of the market

The middle of the market, often abbreviated MoM, is the airliner market between the narrowbody and the widebody aircraft, a market segmentation used by Boeing Commercial Airplanes since at least 2003. Both Airbus and Boeing produce aircraft that serve this segment.

In the Boeing lineup, it is between the largest Boeing 737 MAX 10 of less than 198,000 lb (90 t) of maximum takeoff weight (MTOW) for 204 passengers in two classes over a 3,100 nmi (5,700 km) range, and the smallest Boeing 787-8 of 502,500 lb (227.9 t) for 242 passengers in a 2-class configuration over a 7,355 nmi (13,621 km) range. It was previously covered by Boeing with the largest modern narrowbody, the Boeing 757, typically the -200 for 200 passengers over 3,915 nmi (7,251 km) with a 255,000 lb (116 t) MTOW, and the smallest widebody, the seven-abreast Boeing 767, typically the -300ER for 269 passengers over 5,725 nmi (10,603 km) with a 412,000 lb (187 t) MTOW.

In the Airbus lineup, it is between the A321XLR of 101 t (223,000 lb) of MTOW for 206 passengers in two classes over a 4,700 nmi (8,700 km) range, and the A330-800 of 251 t (553,000 lb) for 257 passengers in three classes over a 8,100 nmi (15,000 km) range. Historically, Airbus's MoM sector was covered by the Airbus A310, which is the shortened derivative of the Airbus A300 and was positioned at the lowest end of the widebody sector. However, unlike Boeing 757 and 767, the A310 was never a commercial success and quickly perished from revenue services, being superseded by its larger and newer sisters Airbus A330.
