The Korean Air Boeing 777-300 carries 338 passengers across Business + Economy. Power is available on this aircraft. Seats are rated below, so you can see which have the legroom, the window alignment and the quiet — and which sit next to a galley or lavatory.
The seats rated best on this map are 1A, 1B, 1D, 1E, 1H, 1J. Another 49 seats are rated best or good. Look for 27 extra-legroom seats for the most room.
Seats rated avoid on this map are 35C, 35G, 36B, 36C, 36D, 36E. Another 66 seats are rated avoid. These are usually the back rows near the galley and lavatories, or middle seats with no window or aisle.
Korean Air's Prestige Class on the 777-300 uses an angled-flat seat in a two-three-two layout — it reclines well but does not lie completely horizontal on all aircraft in the fleet. The product varies slightly by aircraft age. For a fully flat bed, Korean Air's newer aircraft with the updated Prestige Suite seat are the better bet.
Korean Air uses three-three-three abreast on this aircraft, which keeps the economy seat a bit wider than the ten-abreast alternative. For a medium-range sector of five or six hours it is comfortable enough; for very long hauls in economy the seat pitch and personal space matter more, and it is worth checking the pitch figures on the specific route.
The non-ER 777-300 typically handles shorter intercontinental and regional routes from Seoul Incheon — destinations within Asia and some shorter Pacific sectors. For very long routes to the Americas or Europe, Korean Air tends to use the 777-300ER or the A380. It pays to confirm the aircraft type at booking rather than assuming.
