Side-by-Side Comparison Cabin Interiors & Galley Standards

Aircraft Overhead Bins vs. ATLAS vs. KSSU Galley Standards

Comparing 2 standards across 10 specifications. 10 key differences identified.

Comparing:
Aircraft Overhead Bins
ATLAS vs. KSSU Galley Standards

Modern commercial airliner overhead bins utilize pivoting pivot-bin architecture (such as Airbus Airspace XL and Boeing Space Bins) allowing standard 22"× 14"× 9" carry-on bags to be loaded vertically on their side, wheels-in, increasing luggage capacity by up to 60%.

Commercial aircraft galleys adhere to two non-interchangeable international standards for catering service trolleys and Standard Unit (SU) boxes: ATLAS (dominant on ~80% of global airlines, 305 mm cart width) and KSSU (used by KLM, Swiss, SAS, UTA, 301 mm cart width).
