Sơ đồ ghế China Southern Airlines Boeing 777-300ER — 361 ghế

China Southern's current three-cabin, First-less Boeing 777-300ER (csair internal designator '773', page titled 'B777-300ER(773)'). China Southern PUBLISHES per-cabin seat counts and per-cabin pitch/width/recline on its current official cabin-layout dimension page: Business 28 (42–44" pitch, 21.08" width, 180° flat), Premium Economy 28 (38" pitch, 19.2" width, 'sliding seat cushion'), Economy 305 (31–33" pitch, 18.5/16.8/16.3" width, 2–6" recline). There is NO First class. The current csair '777-300ER Experience' page corroborates exactly three cabins: Business ('innovative staggered seat arrangement … convenient access … 180-degree flat seat'), Premium Economy ('fixed backrest recliner … transformed into a semi-circular bed … equipped with a power outlet and a USB port') and Economy ('spacious 3-3-3 configuration … adjustable headrest'). China Southern does NOT publish an exact row grid or a retrievable schematic, so row numbering, column letters, cabin boundaries and the rear taper are DERIVED from the published counts and standard 777-300ER geometry: Business rows 11–15 staggered 2-2-2 (four 6-abreast rows + a 4-seat rear row = 28); Premium Economy rows 21–24 2-4-2 (three 8-abreast rows + a 4-seat rear row = 28); Economy rows 31–64 nine-abreast 3-3-3 (row 31 a bulkhead extra-legroom row, rows 32–63 standard = 297, plus an 8-seat last row 64 with the centre seat removed at the aft galley = 305). Exit-row/door positions are NOT modelled (csair does not publish them); the cabin schematic image on the page could not be archived (absent from the Wayback Machine and the live URL blocks bots), so abreast counts follow the published seat widths, the stated 3-3-3 economy and standard 777-300ER geometry. windowAlignment is left 'unknown' on all window seats (derived grid). No seat-back TV sizes are published on either current page, so IFE screen sizes are omitted. RECONFIGURATION: this 361-seat layout REPLACES China Southern's earlier four-class 309-seat 777-300ER (4F/34J/44W/227Y, csair designator 'B77W', modelled as cz-77w-309) — First class was removed and the cabin densified. The current csair Boeing cabin-layout menu (2024–2025) lists only this one 777-300ER page (361); the old B77W/309 dimension page was last archived in 2020 and no longer appears in the menu. The Wikipedia China Southern fleet table independently lists the 777-300ER as 28J/28W/305Y=361 (15 aircraft in service, Dec 2025), matching this page; the earlier belief that 361 was a mis-attributed non-ER '777-300' figure is therefore superseded — 361 is China Southern's own current published 777-300ER configuration. Whether every one of the ~15 airframes has been reconfigured could not be confirmed from primary/neutral sources (planespotters per-tail data was not retrievable), but csair publishes only the 361 layout.
