KLM Royal Dutch Airlines 777-200ER

KLM's Business cabin on this aircraft is a reverse-herringbone one-two-one layout, so every seat converts to a fully flat bed with direct aisle access. Window seats face slightly towards the fuselage for privacy; centre pairs face each other, which suits companions travelling together. No seat requires stepping over a neighbour.

Three-four-three is ten-abreast — the maximum density for a 777 fuselage and a tight squeeze, particularly for wider passengers. The middle seat of the four-centre block is the most constrained. If you value personal space and cannot upgrade, aim for a window or at least an aisle seat, and consider KLM's Premium Comfort tier as a meaningful alternative.

On a transatlantic or long-haul sector, Premium Comfort delivers noticeably more pitch and a wider seat in a two-four-two layout versus the main-cabin three-four-three. KLM also typically includes enhanced meal service and priority boarding. For flights of eight hours or more it is often worth the difference in fare.
