Five steps from research to ticketed booking. Every step is something our advisors do for you, but helpful to understand the process.
Korean Air Prestige Suites is the top cabin choice, competitive with ANA The Room and Singapore 2017 Business. Prestige Suites 2.0 (787-10 and refitted 777-300ERs) has sliding doors, but they stay open in flight pending regulatory approval; the original Prestige Suites (747-8I, 787-9, many 777-300ERs) has no door. Asiana Business Smartium (staggered 1-2-1 on the A350 and A380) is competitive until Asiana merges into Korean Air on December 17, 2026.
Delta flies non-stop to Seoul from Atlanta, Detroit, Minneapolis, Seattle and Salt Lake City, with the Delta One Suite (closing door, 1-2-1 lie-flat) on its A350 and A330-900neo aircraft. Strong cabin product for US Delta loyalists who want to keep SkyMiles earning and Delta SkyClub benefits.
Cherry blossom peaks late March – early April. Korean Thanksgiving (Chuseok, typically September or October) is a 5-day holiday, Seoul empties but inbound diaspora traffic surges. Both windows push Business fares 25-40% above typical bands.
Korean Air SKYPASS Prestige awards between the US and Korea run 62,500 miles one-way off-peak and 92,500 peak, plus taxes. SKYPASS has no major US bank transfer partner (Chase Ultimate Rewards left in 2018). Delta SkyMiles, Flying Blue and Virgin Atlantic Flying Club can book Korean Air; Aeroplan cannot. Aeroplan and United can book Asiana only for travel through December 16, 2026, when Asiana leaves Star Alliance.
Verify aircraft: Prestige Suites 2.0 is only on the 787-10 and refitted 777-300ERs, while the A380 and some older 777s still fly the older Prestige Sleeper. Asiana Business Smartium is on the A350 and A380.
Three windows, three different price worlds.

Cheapest Business Class to Seoul. Cold but K-pop and shopping districts are at their best.
Published Business Class on US-Seoul routes typically runs $5,500 – $8,500 round-trip in peak, $4,500 – $6,500 off-peak. Through a contracted consolidator, LAX-ICN Business round-trip is regularly $3,400 – $4,200 in shoulder season.
Korean Air Prestige Suites edges Asiana Business Smartium on cabin product, led by the newer Prestige Suites 2.0 with sliding doors (kept open in flight pending regulatory approval) and a 23.8-inch screen. Asiana on the A350 is competitive and often $300-500 cheaper. For frequent flyers: Korean has the deeper US route network; Asiana keeps Star Alliance benefits only until December 16, 2026 and merges into Korean Air on December 17, 2026.
LAX/SFO → ICN: ~12.5-13h westbound, ~11h eastbound. SEA → ICN: ~11.5h westbound. JFK/EWR → ICN: ~14h westbound (the eastbound is just as long because polar route, no significant jet stream help). ATL/DTW/IAD: ~13.5-14h westbound.
Yes. Korean Air SKYPASS Prestige awards from the US run 62,500 miles one-way off-peak and 92,500 peak (Chase Ultimate Rewards stopped transferring in 2018). Virgin Atlantic Flying Club books Korean Air from 85,000 points one-way from the West Coast. Aeroplan books Star Alliance flights to Seoul (such as United and Air Canada) from ~75,000-90,000 miles but cannot book Korean Air. Delta SkyMiles for Delta-operated flights starts at ~90,000 miles. Saver availability is best 6-11 months ahead.
January through mid-March and November through early December are the cheapest. Avoid cherry blossom (late March – early April), Chuseok (September or October), and Lunar New Year (typically late January – mid February).
On Star Alliance redemptions via Aeroplan, a stopover in Tokyo or Hong Kong adds 5,000 points to a one-way award. For cash fares, adding a stopover usually costs $200-500 extra, worth it if you wanted to visit those cities anyway.
The cheapest way to fly Business Class to Seoul is a contracted consolidator fare: the LAX → Seoul Incheon (ICN) routing runs about $3,400 – $5,700 round-trip, typically 30-60% below the airline's published price for the same lie-flat seat. Booking in shoulder season and staying flexible on routing lowers it further; an advisor compares every carrier and gateway on your dates.
Yes. Cheap business class flights to Seoul exist year-round through contracted consolidator inventory rather than public booking sites: business class tickets to Seoul at 30-60% below the published fare, with the identical seat, baggage, and lounge access. The savings are deepest in shoulder season and on one-stop routings; a written quote on your exact dates is free and takes hours, not days.
On the long-haul sectors to Seoul, a lie-flat seat, lounge access and priority services materially change how you arrive. At consolidator pricing 30-60% below the published fare, the gap to a full-fare ticket is small enough that most travelers find Business Class worthwhile, especially on overnight flights.
