Sơ đồ ghế Korean Air Boeing 777-300ER — 291 ghế

Korean Air's older-product three-cabin Boeing 777-300ER. Korean Air (koreanair.com) PUBLISHES the config total ("777-300ER (291 Seats)" in the aircraft menu) and the First and Economy products/dimensions: Kosmo Suites (open First flat-bed, 83-in/211 cm pitch, 26.5-in/67 cm width, 201 cm/79-in bed, 23-in monitor, USB) and New Economy (3-4-3, 33-34 in/84-86 cm pitch, 18.1 in/46 cm width, 118-degree recline, 11.1-in monitor, USB; same product as the 277 config). The per-cabin SEAT COUNTS (8 First / 56 Prestige / 227 Economy) and the Business product name (Prestige Sleeper) come from the current Wikipedia Korean Air fleet table (neutral), which lists this 777-300ER config as Kosmo Suites 8 / Prestige Sleeper 56 / Economy 227 = 291 among 25 in-service 777-300ERs. Korean Air does NOT publish a retrievable row grid or schematic, so row numbering, column letters, cabin boundaries and the rear taper are DERIVED from the published counts and standard 777-300ER geometry: First rows 1-2 (1-2-1 = 8); Prestige Sleeper rows 6-13 (2-3-2 = 7 abreast x 8 rows = 56); New Economy rows 21-43 (3-4-3: bulkhead row 21, standard rows 22-42 = 210, tapered 7-seat last row 43 = 227). Prestige Sleeper numeric pitch/width/screen are NOT published on Korean Air's retrievable cabin pages (that dimension page is not archived) and are omitted rather than estimated; its 2-3-2 abreast follows the older Korean Air long-haul business layout and reconciles the 56-seat count exactly (8 x 7). The 2-3-2 centre seats (column E) are flagged no_direct_aisle_access. Exit-row and door/galley positions are NOT modelled. windowAlignment is left "unknown" on all window seats (derived grid). Power modelled as USB-A per the cabin pages; AC not stated. This 291-seat layout uses Korean Air's older First/Business products; the sister config ke-77w-277 uses the newer Kosmo Suites 2.0 / Prestige Suites products.
