Boeing is announcing plans for a new, longer version of its 737 Max jet at the Paris Air Show in hopes of boosting orders for the single-aisle plane in its race with European rival Airbus.

The CEO of Boeing's commercial planes operations, Kevin McAllister, said Monday that the 737 Max-10 will offer customers more flexibility and seating space. It is expected to cost a bit more than the 737 Max-9, which runs at $119 million according to list prices.

Boeing will this week show off a 737 Max-9, which has struggled to attract customers.

The Max series of jets are designed to be a more fuel-efficient version of the workhorse 737, Boeing's most popular commercial plane. They compete with Airbus planes in the A320-neo family, aiming at a similar short- to mid-range market.

French President Emmanuel Macron is opening the Paris Air Show from the skies.

Macron landed Monday at the Bourget airfield in an Airbus A400-M military transport plane to launch the aviation showcase, where the latest Boeing and Airbus passenger jets will vie for attention with an F-35 warplane, drones and other and high-tech hardware.

Macron, trying to raise his international profile, appears to have chosen the A400-M to give a boost of confidence to the long-troubled European military transporter project.

Thousands are expected at the biennial aviation and defense industry gathering this week.

The industry is eager to show off its wares after a string of public relations embarrassments recently — from the United Airlines' passenger getting dragged off a flight to British Airways' massive outage.
