United Airlines (UAL.O) is set to announce an order for 60 Airbus (AIR.PA) A321 narrowbody jets on Tuesday, a person with knowledge of the matter told Reuters.
The order could also include Boeing (BA.N) jets, said the source, who was not authorized to speak publicly.
Airbus and Boeing did not immediately respond to a request for comment. United declined to comment.
Bloomberg was first to report the Airbus order but did not include aircraft numbers.
Both Airbus and Boeing have laid out ambitious ramp-up goals as air travel and aircraft sales rebound, with Airbus producing in-demand single aisle planes even faster than the U.S. planemaker.
Last year, United Airlines unveiled a huge order of 100 Boeing 787 Dreamliners and 100 737 MAXs to grow post the pandemic and replace older, less-efficient aircraft.
At that time, the order had sparked concerns about United Airlines' balance sheet. The company has said it expects to take delivery of about 700 jets by 2032, the cost of which may reach $50 billion, according to brokerage Jefferies.
The rush to order jets comes amid a boom in travel demand and when airlines are facing increasing pressure to cut emissions.
