MIAMI — China Eastern announced it will purchase 80 Boeing 737 aircraft last Friday.

The order, worth $7.4 billion at list prices, includes sixty 737 MAX jets. The remaining twenty will include current generation models. The breakdown of which specific models (-8, -9, etc) it would choose was not provided. The deal includes a swap in which China Eastern will trade back fifteen 737-300s and five 757s.

The carrier currently operates a fleet of 69 Boeing 737s, split between -300, -700, and -800.

The Shanghai-based carrier already announced a major purchase from rival Airbus in February. The order was for seventy A320neo aircraft, expected to deliver starting in 2018.

In related Boeing news, Turkish Airlines finalized an order for fifteen 737 MAX aircraft. The initial order was placed in May 2013, for a total of 70 aircraft.

“We look forward to making history with China Eastern as they are poised to make the largest purchase for single-aisle airplanes by a Chinese airline,” said Ihssane Mounir, vice president of Sales and Marketing for Northeast Asia, Boeing Commercial Airplanes. “We share an enduring partnership with China Eastern and we are excited to see that the 737 family of airplanes will play an important role in their continued success.”
