The new 777X, Boeing’s first plane in a decade, will be delivered to the U.S. Air Force by the end of 2019, Boeing said.
It is the company’s most expensive plane to date.
The 737 MAX is the same size, but it will be made by Airbus.
Boeing also announced that it is acquiring JetBlue for $17.7 billion.
Boeing is the world’s largest maker of commercial jetliners.
“The new 777 will become the world-leading airline in terms of value, volume, capacity and price,” Boeing CEO Dennis Muilenburg said in a statement.
Boeing, which has made the 777 in part because of the jet’s price, said it will sell the new plane to Air France-KLM, a deal valued at $8 billion.
In March, Muilenberg said Boeing’s 777X was “the most profitable plane in the world,” with an average annualized profit of $7.8 billion, compared with a profit of about $2.4 billion for the 737 MAX.

Air Canada bought the 737 Max in 2019 for $19.5 million.
Air New Zealand bought the MAX for $13.5, while Cathay Pacific Airways bought it for $15.9 million.
Air Canada also owns the Qantas XWB, a Boeing 737-800 that can take off vertically and land vertically.
Other airlines that have made the 737 include Singapore Airlines, Malaysia Airlines, and Air France.
Airlines are buying Boeing planes because of its reliability, but its planes are heavier and more expensive than the MAX.
Boeer also has been struggling to win customers in the U., where it has struggled to make a dent in the jet market.
Last year, Boeing was forced to sell the 737 to the parent company of American Airlines and United Airlines, after the airlines refused to sell their planes to Boeing because they were cheaper.
