Business class travel from New York to Seoul

Korean Air's Prestige Suite on the 787-10 is the product that commands the most attention on this route. The sliding privacy door transforms what might otherwise feel like a premium seat into something genuinely approaching a private space, and the cabin's warm, muted aesthetic reflects a considered Korean design sensibility rather than the sterile functionality you find on too many long-haul products. The Prestige Class lounge at Incheon is among the finest airport lounges in the world — a fact that becomes particularly meaningful given you'll likely connect through ICN rather than treating it as your final stop. Dining aboard is ambitious and largely successful, with Korean signature dishes that feel purposeful rather than performative. For suite seekers and those who treat the journey as part of the experience, Korean Air is the answer. Korean Air also tends to release competitive award availability on this route, making it a strong target for points travelers booking three to four months ahead.

Asiana's Business Smartium is a competent, comfortable product — the 1-2-1 configuration on the A350 delivers genuine privacy and a fully flat bed — but it sits a meaningful tier below Korean Air's hardware in terms of refinement and the sheer drama of arrival. Where Asiana genuinely distinguishes itself is at the table. The galley team consistently outperforms expectations, and the bibimbap and multi-course Korean menu rival anything you'll find on this route. For travelers who believe that a great meal at altitude is the defining measure of a premium experience, Asiana deserves serious consideration. It also tends to price slightly more accessibly than Korean Air in revenue fare classes, making it the sensible choice for value hunters who refuse to sacrifice comfort.

Delta One on the A350 is the right answer for exactly one type of traveler: someone deeply embedded in the SkyMiles ecosystem who wants a genuinely good — if not transcendent — product without the unfamiliarity of a foreign carrier. The suite hardware is solid, the service is inconsistent compared to either Korean carrier, and the dining, while improved, cannot match the authenticity of what you'll find on either Korean flag carrier. Book Delta in the shoulder months of March or September when award space opens and SkyMiles valuations work in your favor — otherwise, the Korean carriers simply offer more for the distance.
