Boeing 737 Max 7

Boeing launched the 737 MAX programme in August 2011 as the fourth generation of the 737 family, positioned to compete with the Airbus A320neo. The MAX 7 made its first flight on 16 March 2018, following the earlier MAX 8’s certification and entry into service in 2017.

Development of the MAX 7 was significantly disrupted by the two fatal 737 MAX 8 accidents (Lion Air Flight 610 (October 2018) and Ethiopian Airlines Flight 302 (March 2019)), which led to a worldwide grounding of the entire MAX family from March 2019 to late 2020. Certification of the MAX 7 was further delayed by a required redesign of the engine anti-ice system, an issue that also affected the MAX 10 and was only resolved in Boeing’s engineering submissions during 2025–2026.

The FAA certified the aircraft on 3 August 2026, some 3,000 days after its first flight, with Southwest Airlines anticipating first deliveries and entry into service in early 2027.

The Boeing 737 MAX 7 retains the standard 737 fuselage cross-section, configured six-abreast in economy (3-3), consistent with other 737 variants. Because seating totals depend on each operator’s chosen layout, exact configurations have not yet been publicly confirmed for any airline

Based on Boeing’s specifications, typical two-class seating capacity is expected to range from 138 to 153 passengers, with a maximum single-class high-density configuration of up to 172.

The dimensions and weights below are for the standard 737 MAX 7 production specification.

The Boeing 737 MAX 7 is exclusively powered by the CFM International LEAP-1B, a high-bypass turbofan developed as the successor to the CFM56-7B that equipped the 737NG family.

As the Boeing 737 MAX 7 has not yet entered service, no operator-specific in-seat amenities or cabin technology have been confirmed. Based on the shared 737 MAX cabin standard, expected features include the Boeing Sky Interior, LED mood lighting, larger pivoting overhead bins, and Wi-Fi connectivity, with specific entertainment and power options to be determined by each launch operator.

Boeing assembles the 737 MAX family at its Renton, Washington facility, with a new fourth 737 production line under construction at Everett, Washington to support planned rate increases.

The Boeing 737 MAX 7 has no operating fleet, as the type has not yet been certified or delivered to any customer. The table below reflects confirmed order commitments rather than active operators.

The Boeing 737 MAX 7 has no incidents or accidents to report, as it is still undergoing certification testing and has not entered commercial passenger service as of July 2026. This section will be updated with any relevant safety information once the type achieves certification and begins operations.

It is worth noting that the wider 737 MAX programme was grounded worldwide from March 2019 to late 2020 following two fatal accidents involving the 737 MAX 8 (Lion Air Flight 610 and Ethiopian Airlines Flight 302), which led to sweeping design, software and oversight changes applied across all MAX variants, including the MAX 7 prior to its eventual certification.
