GECAS also converted an existing 737 order for 20 planes to the new model and Europe's largest tour operator TUI Group did likewise for 18 aircraft.
Although both Airbus and Boeing seemed to enjoy grabbing their fair share of yesterday's order value, an global air show as prominent as Paris virtually always highlights friction between the companies.
At the Paris Air Show, Boeing as expected launched the MAX 10, a larger model of its 737 airplane family.
The first member of the Max family, the Max 8, entered service last month, flying with a Malaysian low-priced airline, Malindo Air. It competes with France-based rival Airbus' A321neo, which has a longer range but is more expensive.
"To have whittled off the checkpoints in the test program so quickly points to the robust maturity of the North Charleston Boeing team as well as the integration maturity of the airplane built on a multi-model line", Ahmad said. "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, and we continue to lead the way again with this commitment for 50 737 MAX 10s and help launch the latest version of the 737".

The other clubs needed time, much more time: Lightning (12 seasons), Ducks (13), Senators (14), Predators (18) and Sharks (24). And to add to all the excitement, the new Golden Knights roster will be revealed during the NHL Awards show in Las Vegas.
"We see a potential need for about 4,000 aircraft in that market".
India's SpiceJet airlines immediately announced it would buy 40 737 MAX airplanes. Boeing said demand for single-aisle planes as well as wide-bodies remains buoyant despite concerns about economic and political turbulence in the Middle East and low fuel prices serving as disincentive to invest in more efficient aircraft.
Airlines are increasingly selecting bigger single-aisle jets.
Leverkuhn said the MAX 10 now completes the MAX family and offers airlines great flexibility.
"I leave it to our customers to tell us if our family is right", said McAllister in a media roundtable here on Sunday. Additional commitments would be detailed later in the week, Boeing said.
"We think the 737 MAX 10 is a competitor to the (MAX) 9 and that's why a lot of people are converting", Airbus sales chief John Leahy told Reuters.
