Dublin (DUB) → Seoul (ICN): cheap fares overview
Dublin to Seoul is a long one — you're looking at somewhere between 13 and 16 hours in the air depending on your connection, because there's no direct service on this route. Most travellers funnel through hubs like Frankfurt, Amsterdam, Dubai, or somewhere in East Asia. That layover city matters more than people think — it shapes the price, the total travel time, and honestly your whole mood when you land. Fares tend to bottom out in the shoulder seasons, late winter and early autumn, and spike hard around Korean school holidays, Irish summer, and the cherry blossom window in April. Business routes pull prices up mid-week too.
Why travel from Dublin to Seoul?
Seoul keeps showing up on people's radar for good reason. The food scene alone is worth the flight — proper Korean BBQ, jjigae at 2am, fried chicken and beer that somehow costs less than a Dublin pint. Beyond that, there's a growing Irish-Korean diaspora pulling people over for family visits, weddings, and the kind of trips that don't fit neatly into a category. K-culture has done real work here — people who grew up watching Korean film and TV are finally making the actual trip. Then there's the hiking, which surprises a lot of Irish visitors. Bukhansan is a mountain inside the city boundary. Seoul also moves fast on tech and urban design in ways that feel genuinely different from any European capital, not just aesthetically but functionally. It's the kind of city that makes you rethink what a city can do.
How to find a cheap fare on this route
Book 8 to 12 weeks out for the best results on this route — last-minute fares here get ugly fast. January through March tends to be the quietest pricing window, outside of Lunar New Year, which you should actively avoid unless you're going for the experience and can absorb the cost. Check connections through Middle Eastern hubs, particularly with EK, as they often undercut European hub routing on this distance. On the Dublin side, DUB has solid connectivity with 201 non-stop destinations feeding into long-haul options. Seoul's Incheon handles 162 non-stop routes, so positioning flights home via Tokyo or Hong Kong can occasionally open up cheaper return combinations worth pricing separately.
