Cheap flights from Dublin to Seoul

The expensive stretch is the one you would expect: school holidays in Ireland lift demand across the summer, and fares climb again around Christmas and the New Year. South Korea adds its own pressure points, with the Lunar New Year in winter and the Chuseok harvest festival in autumn, when seats fill as families travel.

Work back from that and September is the cheapest month on the calendar, with mild weather at both ends and demand settled after the summer. Prices exist for every month of the year here, so you can compare the full spread before committing, and midweek departures usually come in below weekend ones.

The difference you feel first is the shape of the journey: Emirates, Qatar Airways and Etihad connect through their Gulf hubs with a single stop, while Turkish Airlines, Lufthansa and Air France route through theirs. None of them are budget carriers on a trip this long, so meals, checked baggage and a proper seat are normally part of the fare rather than extras.

Aer Lingus and the regional names Emerald Airlines and HOP! usually appear as the short first leg of a connecting ticket, with Juneyao Airlines adding a routing through China. Check whether the whole journey sits on one booking, because a single ticket is far easier to manage if one of the flights runs late.

Incheon International is a vast place — plan for a long walk from the gate to passport control and a wait at baggage reclaim before you reach the arrivals hall. It sits well outside the city, with an express railway running straight to central stations and buses and taxis covering the same route above ground.

Gimpo is smaller and much closer in, so arrivals there are quicker and calmer, with regular rail links into town. Whichever airport your ticket uses, check the last leg before you fly: a late-evening landing at Incheon leaves fewer transport options than one at Gimpo, and the gap in time to the centre is real.

Country facts: Wikidata

• Dublin has a single departure airport, so your only airport decision is which of Seoul's two you land at — check it before you pay.
• Check whether checked baggage is included in the fare, since the regional connecting legs can carry different rules from the long-haul flight.
• Check passport validity and whether South Korea requires a visa or an electronic travel authorisation for your nationality before booking.
• If you buy separate tickets, leave generous time between flights, because the second airline owes you nothing if the first runs late.
• Compare September with the rest of the year, since it prices lowest on this pairing, before locking in your dates.
