737 MAX

Overview

Boeing's current single-aisle aircraft family, spanning the 737-7 through 737-10, built around improved LEAP-1B engines, lower fuel burn, and broad commonality for airline operators.

In active production and airline service worldwide, with the line cleared to rate 47/month after the May 2026 FAA capstone review and a fourth final-assembly line opening at Everett. The FAA certified the MAX 7 on August 3, 2026, with entry into passenger service targeted for early 2027; the MAX 10 completed certification flight testing on July 29, 2026 and is targeting FAA type certification around October 2026, alongside delivered MAX 8 and MAX 9 variants.
