With 12 Airbus A321neo aircraft now in its fleet, United is deploying the type on more scheduled routes starting later this year. Since introducing the new aircraft in November 2023, it has primarily been used on routes from the airline’s Chicago O’Hare hub, including Phoenix, Orlando, and Las Vegas.
Now, the Chicago-based carrier plans to deploy the fleet type farther west from its hub in Denver. According to AeroRoutes, United’s A321neos will fly from Denver to Boston, Houston, Las Vegas, Los Angeles, Orlando, Phoenix, and San Diego starting in December 2024.

The airline has operated the A321neo on flights between Chicago and Denver, which are scheduled to continue through the beginning of next year. United’s A321neo aircraft are equipped with 200 seats, including 20 in first class and 180 in economy.
Per Cirium Fleet Analyer data, the airline has 118 A321neo aircraft on order along with 40 options. United also plans to receive Airbus’ A321XLR for longer-range routes, which is awaiting final certification.
When United took delivery of its initial A321neo in October 2023, it was the first time the airline received a new Airbus jet in over two decades.
