Korean Air 777-300ER Seat Guide (2026) | Cabin
TL;DR
Korean Air's 777-300ER operates in a three-cabin configuration with First Class, Prestige Class (Business), and Economy. Prestige Class is a solid reverse herringbone product with direct aisle access and a fully flat bed, though it lacks privacy doors now standard on competitor products. Economy is 3-4-3 at 10-abreast - tight, requiring deliberate seat selection. Korean Air's soft product and meal quality are genuine differentiators.
Try Cabin
Korean Air's 777-300ER is the workhorse of one of Asia's most underrated premium carriers. The Prestige Class Business product is competitive, and the Economy cabin - at 10-abreast 3-4-3 - requires careful seat selection.
Korean Air operates the Boeing 777-300ER on flagship long-haul routes connecting Seoul Incheon to North America, Europe, and Australia. The airline is a SkyTeam member and frequent codeshare partner with Delta - many passengers encounter this aircraft when booking what appears to be a Delta flight on a Seoul connection.
First Class
Korean Air retains a genuine First Class on select 777-300ER configurations. The product is an open-suite design with 2-metre lie-flat beds, a genuine ottoman, and one of the better western meal offerings in First Class on any Asian carrier. The cabin is small - typically 8 seats in a 1-2-1 layout - quiet, and positioned at the very front of the aircraft ahead of the main Prestige galley. Seat 1A is the standout choice.
Prestige Class (Business)
Prestige Class uses a staggered 1-2-1 reverse herringbone layout. Window seats in odd-numbered rows (A and K) are positioned closer to the fuselage with the console providing a partial privacy screen - the better solo sleeping position. Even-numbered window seats face the aisle more directly. Centre D and G seats in odd rows face each other, making them the best choice for couples. The seat is 21 inches wide and converts to a fully flat 79-inch bed with no privacy door. The Korean Air meal service in Prestige is a genuine highlight: the Bibimbap option, served with proper Korean banchan sides, is consistently cited by frequent flyers as one of the best meals served at altitude. Avoid the last row of Prestige - galley adjacency and light bleed during Economy meal prep are consistent complaints.
Economy Class
Economy is a 3-4-3 layout at 10-abreast. Seat width is approximately 17.2 inches and pitch is 33-34 inches - slightly better than many competitors on the same aircraft type. The IFE screens (9 inches) are functional if not exceptional. Korean cuisine options are available on most routes and rated well consistently. Exit rows offer extra legroom and are the primary targets for comfort-conscious Economy passengers. The centre four-seat block (seats D, E, G, H) should be avoided wherever possible on flights over 6 hours. The rear of the aircraft is louder due to the GE90 engines.
Best seats
Seat | Cabin | Why |
|---|---|---|
1A | First | Furthest from the galley, against the fuselage wall, first to deplane. |
Odd-numbered A & K | Prestige | True window seats with console acting as a privacy screen. Best sleeping position. |
Forward exit row A & K | Economy | Best legroom. Window position avoids the four-seat centre block entirely. |
Seats to avoid
Seat | Cabin | Why |
|---|---|---|
Last Prestige row | Prestige | Galley adjacency and light bleed during Economy meal service. |
Centre 4-seat block D-H | Economy | Four passengers sharing two armrests. Avoid on any flight over 6 hours. |
Last 3 Economy rows | Economy | No recline, GE90 engine noise, galley proximity. |
Does Korean Air 777-300ER Business Class have a privacy door?
No. The Prestige Class reverse herringbone product is an open-suite design without a sliding privacy door. The console provides partial visual privacy from the aisle.
Is Korean Air Prestige Class worth it?
For transpacific routes, yes. The direct aisle access, 79-inch lie-flat bed, and above-average meal quality make Prestige a competitive Business Class product. It trails products with privacy doors on privacy, but leads many competitors on meal quality and crew service.
What is the Economy seat pitch on Korean Air 777-300ER?
33-34 inches - marginally better than many competitors on the same aircraft type. The 10-abreast 3-4-3 layout is tight on seat width at approximately 17.2 inches.
Does Korean Air have Wi-Fi on the 777-300ER?
Yes. Satellite Wi-Fi is available on most long-haul routes with hourly and full-flight packages.
