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 (777-300ER, fully enclosed suite with closing door) is the top cabin choice — competitive with ANA The Room and Singapore 2017 Business. Asiana Business Smartium (newer cabin on A350) is competitive. Both consistently rank in top-10 Business Class cabins globally.
Delta operates ATL-ICN and DTW-ICN with the A330-900neo Delta One Suite (closing door, 1-2-1 lie-flat). 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 Business Class redemptions on US routes run ~125,000 miles + $50-200 one-way. Transfer partners include Chase Ultimate Rewards (1:1). Aeroplan also redeems on Korean Air partner awards. Asiana joined Star Alliance — Aeroplan and United also work for Asiana.
Verify aircraft (Korean Air Prestige Suites are only on the 777-300ER — other aircraft have older Business cabin). Asiana Business Smartium is on A350 and A380 — different products.
Three windows, three different price worlds.
Late Mar – early Apr (sakura), Sep – Oct (Chuseok)
Cherry blossom and Korean Thanksgiving (Chuseok) push fares up 25-40%.
May – Jun, Sep – early Oct
Best weather for Seoul. Fares sit mid-band; awards available.
Jan – mid-Mar, Nov – early Dec
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 (777-300ER) edges Asiana Business Smartium on cabin product — fully enclosed suite with closing door, slightly more storage. Asiana on the A350 is competitive and often $300-500 cheaper. For frequent flyers: Korean has the deeper US route network; Asiana has Star Alliance benefits.
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 Business redemptions run ~125,000 miles one-way (Chase Ultimate Rewards transfers 1:1). Aeroplan via partner redemption runs ~75,000-90,000 miles. 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, stopovers in Tokyo or Hong Kong are typically free of additional miles. Korean Air SKYPASS doesn't allow free stopovers on Business awards. For cash fares, adding a stopover usually costs $200-500 extra — worth it if you wanted to visit those cities anyway.
