Why do two Boeing 737-900ER seat maps look so different?

The same airframe is fitted out very differently by each airline: cabin classes, seat pitch and width, and the number of rows all vary. That is exactly what this comparison table is for.

How accurate are these seat maps?

Every map is drawn to scale from the airline's own configuration and verified against seat pitch, width, and cabin data. Each row shows when it was last verified.
