Sơ đồ chỗ ngồi Korean Air Boeing 777-300ER

Korean Air's newer-product three-cabin Boeing 777-300ER. Korean Air (koreanair.com) PUBLISHES the config total ("777-300ER (277 Seats)" in the aircraft menu) and the seat PRODUCTS and DIMENSIONS per cabin: Prestige Suites (reverse-herringbone business, 75-in/190 cm pitch, 21-in/53 cm width, 180-degree flat bed, 18-in monitor, USB charging) 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). The per-cabin SEAT COUNTS (8 First / 42 Prestige / 227 Economy) and the First product name (Kosmo Suites 2.0) come from the current Wikipedia Korean Air fleet table (neutral), which lists this 777-300ER config as Kosmo Suites 2.0 8 / Prestige Suites 42 / Economy 227 = 277 among 25 in-service 777-300ERs. Korean Air does NOT publish a retrievable row grid or schematic (its seat-map page is JS-rendered/bot-blocked and absent from the Wayback Machine), so the row numbering, column letters, cabin boundaries and rear taper are DERIVED from the published counts and standard 777-300ER geometry: First rows 1-2 (1-2-1 = 8); Prestige Suites rows 6-16 (1-2-1 reverse herringbone: ten full 4-abreast rows = 40 plus a rear partial row of the two window singles = 42); New Economy rows 21-43 (3-4-3: a bulkhead extra-legroom row 21, standard rows 22-42 = 210, plus a tapered 7-seat last row 43 = 227). Kosmo Suites 2.0 numeric pitch/width/screen are NOT published on Korean Air's retrievable cabin pages (only the original Kosmo Suites page is archived) and are omitted rather than estimated. Exit-row and door/galley positions are NOT modelled (Korean Air does not publish them). windowAlignment is left "unknown" on all window seats because the grid is derived. Power modelled as USB-A per the cabin pages' "USB port for charging"; AC not stated. This 277-seat layout uses Korean Air's newer First/Business products; the sister config ke-77w-291 uses the older Kosmo Suites / Prestige Sleeper products.
