Boeing 737 MAX

The Boeing 737 MAX is a series of narrow-body aircraft developed by Boeing Commercial Airplanes as the fourth generation of the Boeing 737. It succeeds the Boeing 737 Next Generation and incorporates more efficient CFM International LEAP engines, aerodynamic improvements such as split-tip winglets, and structural modifications. The program was announced in August 2011, the first flight took place in January 2016, and the aircraft was certified by the U.S. Federal Aviation Administration (FAA) in March 2017. The first delivery, a MAX 8, was made to Malindo Air in May 2017.

The 737 MAX series includes four main variants—the MAX 7, MAX 8, MAX 9, and MAX 10—with increasing fuselage length and seating capacity. Boeing also developed a high-density version, the MAX 8-200, launched by Ryanair. The aircraft typically seats 138 to 204 passengers in a two-class configuration and has a range of 3,300 to 3,850 nautical miles [nmi] (6,110 to 7,130 km; 3,800 to 4,430 mi). As of April 2026, Boeing has delivered 2,267 aircraft and held orders for 4,852 more. The MAX 8 is the most widely ordered variant, while the MAX 7 and MAX 10 have not yet received FAA certification, and the agency has not provided a timeline for their approval. Its primary competitor is the Airbus A320neo family, which occupies a similar market segment.
