China Southern Boeing 737-800, fleet-tracking code 738 (8J/24W/132Y = 164). PER-CABIN COUNTS AND DIMENSIONS ARE PUBLISHED/PRIMARY: China Southern's official B737-800(738) cabin-layout page (csair.com, via the 2024-06-15 Wayback snapshot) lists Business/Premium Economy/Economy seat counts, pitch, width and recline for this configuration; the Wikipedia China Southern fleet table (neutral) corroborates the 8J/24W/132Y=164 split among the airline's 153 Boeing 737-800s and cites the same csair.com page. NOTE: China Southern markets the Premium Economy cabin as "Economy Class" on international routes (per the source page); it is modelled here as premium_economy by canonical tier, matching the corpus convention set by cz-789-276. THE ASSIGNMENT HINT (1 config ~8J/156Y) IS SUPERSEDED: China Southern publishes FOUR distinct 737-800 cabin configurations — 738 (8J/24W/132Y=164), 73M (4J/24W/150Y=178), 73Q (4J/18W/147Y=169) and 73N (4J/18W/150Y=172); the ~164-seat total of the hint corresponds to config 738, but the published split is 8J/24W/132Y, not 8J/156Y. LAYOUT DERIVED_FROM_COUNTS: the csair map is a reference image only, so the row grid, cabin boundaries, over-wing exit band, doors/galleys/lavatories and the tapered last Economy row are structural reconstructions from the published counts + standard 737-800 (2-2 Business, 3-3 Premium Economy/Economy) geometry; every cabin carries derived:true. DERIVATIONS: Business 2-2 rows 1-2 (8); Premium Economy 3-3 rows 3-6 (24); Economy 3-3 rows 7-28 (132), bulkhead row 7, two over-wing exit rows 16 (forward, modelled no-recline) and 17 (aft, normal recline), the row 15 immediately ahead of the forward exit modelled limited-recline, and the final Economy row is 28. Per-row recline specifics are derived from standard 737-800 certification geometry; the airline publishes only per-cabin recline ranges (published recline set 0/1/3/4.5 in), preserved in the seat-type legroomNotes. windowGridType is bound to the shared 737-800 engineering grid; window seats are left windowAlignment "unknown" on this derived grid except structural blanks applied by window-alignment.js. Continuous row numbering (1..N) is a derived modelling choice. The per-config airframe split of the 153-aircraft 737-800 fleet is not published.
