June 6, 2024, © Leeham News: We do an article series about the all-important cabin and its seating for an airliner. We have looked at different narrowbody cabins and how the seating differs widely depending on the market and customer segments the aircraft addresses.

This week, we focus on why widebody aircraft have relatively low seat counts compared with single-aisle aircraft, like the A321neo.

We use the cabin generator in our Aircraft Performance and Cost Model (APCM) to configure widebody cabins and compare these with the narrowbody equivalents.

Summary:

• The widebody cabins are configured for longer flight times, resulting in them taking more space.
• When a widebody is configured for domestic flights, its seating per cabin area is closer to that of a narrowbody.
