Boeing revealed that Chinese aircraft lessor CDB Aviation Lease Finance has placed an order for 30 of its new single-aisle 737 MAX 8 jets. The order was booked earlier and was previously listed on Boeing’s orders website as coming from an unidentified customer. The order is worth $3.3 billion at current list prices, but based on market valuation data from aircraft valuation firm Avitas, the real value after standard industry discounts is about $1.5 billion.
