Boeing has announced a tentative order from Indonesia's Garuda airline for up to 60 jets at the opening of the Paris Air Show.

The planemaker said Monday that Garuda signed a letter of intent to buy up to 30 its popular single-aisle 737 MAX and 30 of Boeing's 787-9 jets. The 60 jets, if confirmed, would cost 10.8 billion dollars at list prices, though airlines usually negotiate discounts.

Rival Airbus announced Monday that it has made a deal with Saudi Arabian Airlines to be the first airline to fly the Airbus A330-300 regional jet, redesigned for domestic and regional routes.

Thousands of people streamed into the world's oldest air show Monday from throughout the world's $700 billion aerospace and defense industry.
