Iberia Airbus A350-900 seat map

CURRENT A350 NEXT CONFIG. Iberia's November 2025 account of flight IB307 explicitly identifies an operating A350 Next with 31J/28W/293Y=352. Iberia publishes a detailed A350 Next virtual product tour, but no row-by-row Next map was located in permitted sources; every cabin and row is therefore marked DERIVED, and furniture/wing placement is omitted. The grid uses the published cabin counts and 1-2-1 / 2-4-2 / 3-3-3 product geometry. Official virtual-tour scene IDs prove seats 4H, 12D and 25D exist; otherwise, row bounds and missing-seat positions are best-effort reconstructions. Business uses rows 1-8 with one omitted suite in derived row 1 (3+7x4=31); Premium Economy uses full rows 12-14 plus outer pairs in row 15 (24+4=28); Economy uses the same 293-seat arithmetic as the classic layout because Iberia publishes the same Economy count, not because a Next row map proves it. The Next-specific virtual tour publishes an 18-inch Business screen, while Iberia's generic A350-900 seat page says 18.5 inches; the more specific 18-inch value controls. Window alignment remains unknown. No retrofit relationship is encoded because the permitted current sources prove coexistence but do not establish an active conversion program between these configurations.
