October 30, 2025, © Leeham News: We went through the creation of Airbus’s A321 in the first article, and why its initial sales were slow, and why the sales only picked up after the launch of the A320/A321neo models, and how it came to dominate sales and deliveries in the A320 family after COVID.
For an airline, it’s now a matter of what mix of the different A321neo variants to buy. Is there a large penalty to “misuse” an A321LR or XLR on shorter routes, or can a fleet of the more expensive and heavier models be used on shorter routes to cover gaps and increase their daily utilization without a cost penalty?
To get the answer, we look into the different A321neo variants and compare their capacities and operational costs in this article using the Leeham Aircraft Performance and Cost Model, APCM.
