TOKYO, JAPAN — Japan's Tokyo, Haneda-based low-cost operator Skymark Airlines today announced the airline's plan to add up to 12 737 MAX jets as part of its fleet modernization efforts. The carrier intends to order four airplanes, including the 737 MAX 8 and 737 MAX 10 variants, with options for two additional jets.

Separately, the airline will lease six 737 MAX 8s from several lessors. Skymark Airlines is Japan's third largest carrier by revenue and currently operates an all-Boeing fleet of 29 Next-Generation 737-800s.

"As Skymark Airlines looks to grow its fleet sustainably, the 737 MAX family offers market-leading efficiency and environmental performance," said Ihssane Mounir, Boeing's senior vice president of Commercial Sales and Marketing.

"With commonality and enhanced capabilities, the 737-8 and 737-10 will enable Skymark Airlines to optimize its fleet across all operations."

The 737 MAX reduces fuel consumption and carbon emissions by 20% and the noise footprint by 50% compared to the airplanes they replace. The 737 MAX family has the latest CFM International LEAP-1B engines, advanced technology winglets, and other aerodynamic enhancements to improve performance and reduce operating costs.

Nearly 50 airlines globally are currently operating approximately 3,000 daily revenue flights with the 737 MAX. Since late 2020 the in-service 737 MAX fleet has made over one million revenue flights totaling more than 2.5 million flight hours with 99.5% schedule reliability.

The 737 MAX Family jets are the best-selling commercial aircraft of the American aircraft manufacturer. The aircraft returned to service in June 2021 from a nearly two-year grounding after two deadly crashes in less than six months. Boeing was expecting its smallest MAX 7 and the largest MAX 10 variants to be certified in December, but the manufacturer had to push back certifications after new requirements imposed by the American Congress.
