Boeing Co. won an $8.5 billion order from Japanese lessor SMBC Aviation Capital Ltd. as Asian aircraft-leasing companies bet on demand for new planes to serve the region's travel growth.

The order was for 80 737 Max 8 models for delivery between 2018 and 2022, SMBC said in a statement Monday.

The contract value is based on list prices and purchasers usually get a discount. The deal is the largest single order for 737 Maxs by a lessor, according to the statement.
