Previous undisclosed customer of 737 Max 10's confirmed as Lion Air Group

Boeing  confirmed today that a previously unnamed customer of  the US manufacturer's 737 Max 10 aircraft is Lion Air.  
The airline is taking 50 of the new 737 MAX 10 aircraft that the Boeing claims is the most fuel-efficient and profitable single-aisle jet in the aviation industry. The deal has a true value of $4.98 billion and is one of Boeing's largest orders for the  737 Max airframes. 
"Lion Air is very excited to be a launch customer of the latest version of the 737. This aeroplane delivers a new level of fuel efficiency and operating economics and fits in perfectly with our fleet of modern aeroplanes," said Edward Sirait, President Director, the Lion Air Group. "We are proud to continue our tradition of innovation at Lion Air as we again lead the way with new aeroplane technology."
The Lion Air Group was first in the world to put the 737 MAX 8 into service and the first to order the 737 MAX 9. Last month, the group became the first to take delivery of a 737 MAX 9, using the aeroplane's added capacity to launch several international routes.
"We are honoured that Lion Air Group, one of the most innovative and fast-growing carriers, has once again placed its trust in the 737 family," said Dinesh Keskar, senior vice president, Asia Pacific & India Sales, Boeing Commercial Airplanes. "With the 737 MAX 10, Lion Air will have a range of efficient and reliable options to optimize their network to serve their customers and grow profitably."
