Sơ đồ chỗ ngồi Korean Air Boeing 777-300

Korean Air Boeing 777-300 (non-ER; IATA 773 / ICAO B773) — a two-class domestic/regional widebody. As of July 2026 Wikipedia’s Korean Air fleet table lists 4 of these -300 (non-ER) in service, distinct from the 25 777-300ERs (ke-77w-*); the 777-200ER was retired in 2025. GRID: read cell-by-cell from Korean Air’s own published seat-map diagram (fl-777-300-338-seatmap-pc.png, DAM-dated 2025-09-03) at native resolution, hence layoutProvenance published_map. Prestige (cabin "C") is 2-3-2: row 1 is a 2-2-2 bulkhead (A B / D E / H J, 6 seats) and rows 7,8,9,10,11 are 2-3-2 (7 each) = 41. Economy (cabin "Y") is 3-3-3, rows 28-63: front block 28-36 full (row 37 is centre-only D E F), middle block 40-50 full (rows 38-39 are window-pairs-only beside the door-3 lavatory bank, row 51 is A B C beside the door-4 galley/lav), rear block 52-62 full (row 63 loses C and G to the tail taper) = 300. PER-CABIN SEAT PRODUCTS/DIMENSIONS come from Korean Air’s current 777-300 cabin pages: Prestige Class is a 180-degree flat-bed sleeper, 74 in (188 cm) pitch, 20.1 in (51 cm) width, 73 in (185 cm) bed, 15.4 in monitor, in-seat power + USB (A-type); Economy (New Economy slimline) is 32-34 in (81-86 cm) pitch, 18.1 in (46 cm) width, 118-degree recline, 10.6 in monitor, in-seat power + USB (A-type). Both cabins: no Wi-Fi (specWifi=false). SEAT-COUNT DISCREPANCY: Korean Air’s product slug names this aircraft "300-338" (=> 338 total) and Wikipedia’s fleet table lists 41 Prestige / 297 Economy = 338. Business (41) matches exactly; economy differs by 3 (published seat-map diagram shows 300, the 338/297 sources show 297). The seat-map image is the most current (2025-09) and most granular Korean Air primary source and was transcribed and counted three times, so it is treated as authoritative for the grid (41 Prestige / 300 Economy / 341 total). The 3-seat economy difference is documented and unresolved — likely a minor recount or reconfiguration post-dating the 338 marketing figure. No seats were invented or deleted to force a match; the grid reflects exactly what the diagram depicts. ICONS from the seat-map legend (fl-icon-*.png): extra-legroom (regroom) seats at the bulkhead/exit rows 28, 38 and 52; paid "preferred" seats (standard legroom) at rows 29-32; accessible seats at 28F/29E/29F/31E/31F; in-cabin-pet seats at 11J/34J/47J/60J. Extra-legroom and preferred seats carry paid_seat; preferred rows are modelled as a cabin zone. Extra-legroom rows are rated good; preferred rows are standard (location, not a physical advantage). Row-grid attributes (bulkhead / exit proximity / bassinet / last row / partial row) are read from the diagram; the aircraft’s window-body alignment is not published, so window seats carry windowAlignment "unknown".
