Avoid: Even-numbered rows offer less foot room, problematic for taller passengers. Seats near the mid-cabin galley (between main and mini cabins) experience more noise and traffic. Row 12 is closest to premium economy. Reverse herringbone 1-2-1 layout with direct aisle access from every seat. The mini-cabin (rows 9-12) is genuinely secluded and highly sought after. No privacy doors on this variant. Panasonic Ku-band WiFi; Starlink retrofit underway. 48-seat Polaris cabin is the standard long-haul 787-9 configuration.
