United Airlines is set to receive up to 87 new aircraft over the next nine months, with the Boeing 737 MAX 9 as the backbone of these deliveries.
The airline currently has a backlog of more than 123 MAX 8s, 159 MAX 9s, and 165 MAX 10s awaiting delivery.
United is already the largest operator of the MAX 9, and the continued arrival of these aircraft will likely be configured in the 179-seat layout.

The airline's 'United Next' strategy aims to extend and modernize its fleet, which has been critical to its recovery post-pandemic.
With deliveries of the A321XLR set to begin this year, United plans to accelerate the retirement of the 757-200.
Aircraft orders exceed 600, with the MAX aircraft widely anticipated to support the retirement of aging Airbus narrowbodies.

The airline's fleet size is expected to continue growing, driven by its gradual retirement of older aircraft and new deliveries.
United's continued expansion into the MAX fleet will likely be crucial in supporting its growth plans.
As the largest US carrier by fleet size, United's commitment to modernizing its fleet will remain a key focus for the airline.

The continued arrival of MAX 9s will likely be configured in the 179-seat layout, which includes 20 Domestic First, 45 Economy Plus, and 114 Economy.
