The order, which has a list-price of $7.2 billion, is the first 737 Max order by a leasing company, Boeing said in Monday’s statement.
Boeing also added the firm order includes reconfirmation rights for another 25 737 Max aircraft.
In pre-market trade, Boeing’s share price moved 51 cents higher, or 0.69 per cent, hitting $74.20 on the New York Stock Exchange.
In the statement, Air Lease Corp.’s chief executive, Steven Udvar, said the plane "is an excellent addition" to its portfolio and "the ideal complement" to its growing fleet of Next-Generation 737-800’s.
"The 737 MAX represents a step-change improvement that our airline clients need to compete in the future," he said.
To date, Boeing said it has orders and commitments for more than 1,000 737 Max airplanes.
Airlines operating the new single aisle plane will notice a 13 per cent fuel burn improvement, the company noted.
