3 airlines go head-to-head on the ZRH–ICN route. Compare seats, lounges, and fares from $2,200.
3 airlines fly business class from Zurich (ZRH) to Seoul (ICN), with round-trip fares ranging from $2,200 to $6,500. The average flight time is 11 hours. SWISS and Korean Air are the primary competitors on this route. The most affordable fares typically appear in January, February, March.
The eleven-hour journey in business class from Zurich to Seoul is genuinely competitive, with three distinct airlines offering meaningfully different experiences — and choosing the wrong one for your priorities is an easy mistake to make. To state it plainly: Korean Air's Prestige Suite on the 787-10 is the most private hard product on this route, British Airways' Club Suite offers a strong middle ground between privacy and service consistency, and SWISS delivers the warmest cabin culture but the least enclosed seat of the three.
Korean Air is the suite seeker's answer here. The sliding privacy door on the Prestige Suite transforms what is already a generous 1-2-1 configuration into something approaching a genuine private cabin, and the 787-10's superior cabin pressure and humidity levels make an eleven-hour overnight far more restorative than it has any right to be. The Incheon lounge arrival experience, with its shower facilities and Korean dining counter, is also a legitimate competitive advantage for those connecting onward into Asia. Korean Air tends to release its most competitive fares on this routing in January and February, when demand from European leisure travelers softens considerably.
SWISS rewards a different kind of traveler. The staggered 1-2-1 configuration on the A330 and 777 lacks a door, but the Swiss galley culture — the Cheese Trolley, the regional wine program, the unhurried meal pacing — turns the dining portion of a long-haul flight into something genuinely pleasurable rather than functional. If you are departing Zurich, SWISS also offers home-airport advantages that matter: shorter transit times, familiar check-in infrastructure, and the SWISS First Class Lounge at Zurich, which is among the finest departure lounges in Europe regardless of your cabin. British Airways connects via London Heathrow on most itineraries, which adds connection time but gives Club Suite passengers access to the Concorde Room if positioned correctly — a worthwhile trade for some.
The insider tip worth acting on: October and November represent a sweet spot on this route, when shoulder-season fares drop but the product and service levels remain at full strength ahead of the holiday push. Fares shift quickly and without warning across all three carriers here, which makes setting automated price alerts on this specific routing — rather than checking sporadically — the single most reliable way to secure the cabin you actually want at a price that makes sense.
