en.Wedoany.com Reported - Boeing is accelerating the certification process for the 737 MAX 10, with approval expected in 2026 alongside the 737 MAX 7. The 737 MAX 10 has an order backlog of over 1,400 aircraft, more than four times that of the MAX 7, providing a financial incentive for Boeing to prioritize the MAX 10. The MAX 10 is seen as a key product to compete with the Airbus A321neo, which dominates the narrow-body market.

For Southwest Airlines, this prioritization presents challenges. As the largest customer for the MAX 7, holding approximately 90% of orders, Southwest plans to use this model to replace its aging 737-700 fleet. Southwest expects to receive 101 MAX 7s and 66 MAX 8s in 2026, but delays to the MAX 7 have already impacted its fleet renewal process. The MAX 7 is primarily used in lower-density markets with a range of 3,800 nautical miles; the MAX 10 focuses on high-demand routes, with a typical seating capacity of 188 to 204 passengers.

Boeing stated that both models will receive certification in 2026, with customer deliveries beginning in 2027. The prolonged delays were mainly caused by issues with the engine anti-ice system, and testing is now in its final stages. Southwest Airlines expects that once certification is complete, its long-awaited MAX 7s will be delivered quickly, but the final timeline still depends on the progress of certification.
