Lie-flat into Incheon on Korean Air, Delta and their partners: quoted below the published fare.
Business class to Seoul, South Korea lands at Incheon International (ICN), the purpose-built hub about an hour west of the city, routinely ranked among the world’s best airports. Every long-haul premium cabin comes through Incheon; Gimpo handles domestic and short regional hops.
The market is mid-reshuffle: Korean Air completed its takeover of Asiana in late 2024, and the two are gradually combining into one SkyTeam giant. Meanwhile both brands still sell seats, Delta flies its own metal in a joint venture with Korean Air, and United and American add their own nonstops: competition that keeps Incheon business fares negotiable.

Seoul peaks in the summer holidays, around Chuseok (September–October, dates shift yearly) and over Lunar New Year. Spring and fall bring the best weather and steady demand, so book three to five months ahead for those. January–February outside Lunar New Year is the softest window, with the lowest fares.

As of August 2026, retail round trips run about $3,800–$6,800 from the U.S. West Coast and $4,200–$8,200 from the rest of the country. Biirdee sources fares below retail.
Korean Air, Asiana, Delta, United and American all fly lie-flat business class nonstop from the U.S. to Seoul Incheon (ICN), with one-stop options via Tokyo, Taipei and other Asian hubs.
Korean Air acquired Asiana in late 2024 and the brands are merging over the next few years. For now Asiana still sells under its own name and remains a legitimate business class option.
January–February outside Lunar New Year, plus late fall after Chuseok. Summer and the Korean holiday periods are the most expensive in the business cabin.
