cabin

All-Aisle Access

Direct Aisle Access (Business Class)

Definition

Business-class seat configuration where every passenger can reach the aisle without climbing over another passenger.

Why it matters

Reverse-herringbone is the most common all-aisle configuration (United Polaris, Cathay business, Delta One). Some older 2-2-2 layouts (Lufthansa older 747) require window-seat passengers to climb over aisle-seat passengers.
