United Airlines (UA, Chicago O'Hare) has announced a firm order with Airbus for fifty A321-200neo(XLR)s with deliveries starting in 2024. The twinjets will act as a replacement for the carrier's ageing B757-200s.

"The new Airbus A321neo(XLR) aircraft is an ideal one-for-one replacement for the older, less-efficient aircraft currently operating between some of the most vital cities in our intercontinental network. In addition to strengthening our ability to fly more efficiently, the A321neo(XLR)'s range capabilities open potential new destinations to further develop our route network and provide customers with more options to travel the globe," Executive Vice-President and Chief Commercial Officer Andrew Nocella said.

The airline said in a press release that in addition to replacing the B757-200s, the A321neo(XLR) will allow it to "explore serving additional destinations in Europe from its East Coast hubs in New York Newark and Washington Dulles."

According to the ch-aviation fleets advanced module, United currently operates fifty active B757-200s and has a further three units on the ground. The average age of this subfleet is 23.4 years. United owns all of its B757-200s.
