Korean Air Prestige Class (Prestige Suites) cabin on the A330-300

Korean Air's newer A330-300 business cabin is the Collins Aerospace (formerly B/E) Apex Suite — marketed as Prestige Suites — in a staggered 2-2-2 layout with 24 seats. Window seats sit offset behind the adjacent aisle seat, creating a private corridor that gives every seat direct aisle access.

Spot it

  • Staggered 2-2-2 where window seats sit aft of the aisle seat with their own corridor
  • Collins Aerospace (B/E) Apex Suite — same seat as Korean Air's 787-9 and legacy 777-300ER Prestige cabins
  • No suite door — high shells and dividers instead

Korean Air Prestige Class (Prestige Sleeper) cabin on the A330-300

Korean Air's older A330-300 business cabin, the Prestige Sleeper, is a fully flat 180-degree bed seat in a standard 2-2-2 layout. Because the seats are not staggered, window passengers do not have direct aisle access and must step past the adjacent aisle passenger.

Spot it

  • Straight 2-2-2 rows with seats aligned, not offset
  • Window seat pairs share a single aisle with no direct access for the window seat
  • One-touch flat-bed recline with adjustable backrest and legrest

Route shares are the share of Korean Air's observed flying on a tracked route that is this cabin, resolved from flight history to individual registrations. They describe the routes we track, not Korean Air's whole A330-300 fleet — a version we haven't measured would not appear here at all.
