Industry reports indicate that theBoeing 737 MAX 7 could receive final FAAcertification in the latter weeks of July 2026, bringing an end to a multi-year regulatory limbo caused by the aircraft’s engine anti-ice system redesign. While the approval would mark a major milestone for Boeing, its significance is arguably even greater for Southwest Airlines. The carrier has 314 MAX 7s on order to replace its aging fleet of 334 Boeing 737-700s and expects the type to enter passenger service in the first quarter of 2027. Southwest previously evaluated the Airbus A220but ultimately chose to preserve its single-fleet Boeing operating model, with the long-term goal of becoming an all-MAX airline by 2031.
