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. As of mid-July 2026 the MAX 7 has finished certification flight testing (deliverables ~95% complete, certification expected within weeks) and the MAX 10 is ~98% through, targeting approval by year-end — alongside delivered MAX 8 and MAX 9 variants.
