October 26, 2023, © Leeham News: We do an article series about what can be the next development for Airbus' most popular aircraft, the A321neo. We looked at a minimal makeover in Part 3; now, we make a larger change.

We use our Airliner Performance and Cost Model (APCM) to examine what a new wing and revised engines can bring regarding larger passenger capacity, range, and lower seat-mile costs.

Summary:

• To increase the capacity significantly of the A321, a new wing is needed.
• We design a new wing combined with uprated engines and look at the result.
