Cheap Flights Dublin to Seoul 2026 — Fares, Airlines & Best Time to Book

Dublin to Seoul has no non-stop flight, but South Korea’s capital is a straightforward one-connection trip: Emirates, Qatar Airways, Turkish Airlines and Finnair all link Dublin to Incheon International with a single stop at their hubs. This guide covers who flies the route, what a fair return costs in euros, and when to book — plus why the journey runs a little longer than the map suggests.

Fares from Dublin to Seoul (EUR)

Seoul is a year-round destination, but fares track Korea’s travel seasons. Spring (April–May, cherry blossom), the crisp autumn weeks (September–October) and the Christmas/New-Year peak are the priciest; the cold midwinter (January–February) and the humid, rainy summer are the cheapest. The table below shows when the route is busiest. We no longer print per-month fare estimates here, because they were never measured.

We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.

Airlines on this route

No airline flies Dublin to Seoul non-stop, so every option involves a single change of plane. Note that since the closure of Russian airspace to European carriers, Europe–Korea flights route south of Russia and take longer than they once did — the Gulf hubs (Dubai, Doha) are naturally on that southern path, while Finnair’s Helsinki routing, once the fastest to Asia, is now longer than before.

One-stop (usually cheapest, about 14–18 hours total):

• Emirates via Dubai — frequent, strong economy, and regularly among the best-value fares from Dublin to Incheon.
• Qatar Airways via Doha — a highly rated single-stop routing that often carries the lowest fare on the route.
• Turkish Airlines via Istanbul — a daily, well-priced one-stop with a generous baggage allowance.
• Finnair via Helsinki — a straightforward European connection with one change, competitive when on sale.
• Etihad via Abu Dhabi — a comfortable Gulf alternative when its fares line up.

Because these carriers compete hard on the Europe–Korea corridor, fares move around a lot. Compare Qatar and Emirates against Turkish and Finnair for the same dates — the cheapest is rarely the same airline twice.

When to book & how to save

• Book 2–4 months ahead for the best balance of price and choice; long-haul fares to Seoul rarely get cheaper in the final weeks.
• Avoid the peaks if you can: the April–May cherry-blossom weeks, the September–October autumn season and the Christmas/New-Year holidays are the most expensive and busiest.
• Travel in midwinter (January–February) for the lowest fares — Seoul is cold but crisp and clear, and the city’s food and culture are indoor-friendly.
• Weigh the connection, not just the price: a tight Gulf transfer can be shorter overall than a long Istanbul or Helsinki layover, even at a similar fare.
• Check checked-bag rules: full-service carriers to Korea usually include 23–30 kg, but the cheapest “light” fares may not — compare the all-in price with bags.

Arriving in Seoul

You land at Incheon International (ICN), about 50 km west of central Seoul and consistently rated among the world’s best airports. The easiest way in is the AREX Airport Railroad: the express to Seoul Station takes about 43 minutes (roughly €7–€9), while the cheaper all-stop train connects to the metro. Airport limousine buses serve the main districts directly, and taxis into the city run well over €50. Korea uses the won; check the current K-ETA travel-authorisation requirement before you fly, as the rules for Irish and other nationalities have changed recently.
