Sơ đồ chỗ ngồi All Nippon Airways Boeing 777-300ER

ANA Boeing 777-300ER "New 212 seats" config (8 First / 64 Business / 24 Premium Economy / 116 Economy). Row grid, exit/door positions, no-window seats (30A/30K), bassinet and lavatory/galley positions all read from ANA's official accessible seat-map description at ana.co.jp (.../seatmap/international/b777_300er_1/), so layoutProvenance = published_map. FIRST rows 1-2 (1-2-1, A|D,G|K). BUSINESS THE Room rows 5-20 (1-2-1 with a sliding door and direct aisle access from every seat), alternating rear-facing rows (A|E,F|K, seat letters A/E/F/K) and forward-facing rows (C|D,G|H) — 16 rows x 4 = 64; a single cabin.columns set of 8 letters is used with cabin.layout omitted because seat letters differ by row. PREMIUM ECONOMY rows 25-27 (2-4-2 = 24). ECONOMY rows 30-42 (3-4-3): row 30 is the Door 4 exit row with the center block removed (A,B,C / H,J,K = 6), rows 31-38 full (10), rows 39-41 taper to 2-4-2 (drop B,J), row 42 partial (A,C,D,E,F,G) = 116. Emergency exits both sides at front, in front of row 7, behind row 16, in front of row 30, and at the rear. Bassinets 16D/16H/20D/20H/25A/25E/25F/25K/31E/31F. This config supersedes the legacy staggered 777-300ER (nh-77w-legacy) as ANA retrofits THE Room across the fleet. DIMENSIONS: published by ANA on its cabin pages — First 43-inch 4K monitor + sliding door + personal closet; THE Room 24-inch 4K monitor; Premium Economy 38-inch pitch + 15.6-inch monitor; Economy 34-inch pitch + 13.3-inch monitor (11.6-inch first row). Seat widths and bed lengths for First/Business are not published on the cited ANA pages and are omitted rather than estimated. windowAlignment left "unknown" for real window seats (published map does not prove per-window alignment); "none" only for the published no-window seats 30A/30K.
