[1] The method attempts to eliminate the buffers that slow down plane boarding,[2] while simultaneously optimising speed and efficiency.
The method has been criticised for its lack of human headway, as it would separate those boarding in groups, require a perfectly organised line, as well as uniform stowing and seating time.
[8] In an attempt to rectify this, Jason Steffen conducted simulations and experiments to calculate the mathematically quickest way to board a plane.
[9] It eliminates the buffers of climbing over already occupied seats and multiple people stowing in a line.
[10] Steffen's method has been criticised for not giving leeway to human imperfections and needs, including keeping together boarding groups/children and adults, lateness, and organising large groups into a single file line ordered perfectly.
