Boeing Co. isn't waiting for next month's Farnborough International Airshow to unveil blockbuster aircraft deals — or start booking cash.

The Chicago-based plane maker is poised to bolster its backlog with orders valued at $14.4 billion thanks to two transactions announced Monday. That's a break from an industry practice of stockpiling sales for the biggest annual trade expo, which alternates between Paris and Farnborough, outside London.

Bamboo Airways, a Vietnamese start-up, signed a commitment for 20 of Boeing's twin-aisle 787-9 Dreamliners, the companies said in a statement. That's a deal of about $5.6 billion before customary discounts. Earlier in the day, Jet Airways India Ltd. announced it was purchasing 75 of Boeing's 737 Max single-aisle planes, a transaction valued at $8.8 billion based on list prices.
