Cheap flights from Dublin to Hong Kong

The further ahead you book on a haul of this length, the better the fare tends to be, and December and January need the most lead time because the Christmas rush and Chinese New Year fill the planes. September is usually the cheapest month to fly this route, since the summer peak is over and the winter season has not begun. October and November stay calm as well, and the spring months are generally quieter than midsummer. Midweek departures often cost less than weekend ones, and the full-year price calendar on this page lets you slide your dates and watch the fare move with the season.

Most of the capacity here is full-service — Turkish Airlines, Swiss, Cathay Pacific, China Eastern Airlines, China Airlines and Juneyao Airlines fly the long haul with meals and a checked bag usually part of the fare — while the budget side is thin, with Vueling Airlines the clearest low-cost name on the shorter first leg. Lufthansa City Airlines and Nordic Regional Airlines work as regional feeders into their groups' hubs, while Hahn Air mainly issues tickets that span several carriers. Nothing flies nonstop, so every booking includes a connection; keep the trip on one ticket and the airline rebooks you if a leg runs late, while split bookings leave that risk with you.

Hong Kong International is a vast airport by any standard, and the size matters on arrival: the walk from your gate to immigration and the baggage belts can take a good while, so build it into your first hour. The airport sits on Lantau Island, well apart from the central districts, which makes the ride into town something to plan rather than improvise — the Airport Express train runs straight to the heart of the city, buses cover the districts the train skips, and taxis queue outside arrivals. Pick up a stored-value Octopus card at the terminal so your first train or bus needs no cash, and if you land during a holiday peak, expect longer queues at immigration.

Country facts: Wikidata

• Check whether your connection sits on one ticket or two, since on split bookings the second airline owes you nothing if the first flight runs late.
• Check the layover leaves enough time to change terminals and clear transfer security at the hub.
• If a budget carrier such as Vueling Airlines operates your first leg, check whether a checked bag is included or costs extra.
• Check the entry rules for Hong Kong, including how long your passport must stay valid.
• Look at your dates against the Christmas rush and Chinese New Year, when fares climb and planes fill up.
• If your dates are flexible, try September first, since it usually brings the lowest fares on this route.
