Cheap Flights from Lisbon to Dublin

The route from Lisbon to Dublin covers about 1,643 km (1,021 miles). A nonstop flight, when scheduled, usually takes around 2h 40m gate to gate, although total trip time still depends on airport queues, transfer costs, and how early you need to arrive. Because this is one of the longer intra-European combinations in the batch, schedule quality matters almost as much as the headline price. If you only see one-stop options on your travel dates, connections through Amsterdam or Barcelona can widen the fare mix, but total journey time often stretches to 6 to 8 hours.

For many travelers, the cheapest time to fly from Lisbon to Dublin is outside St Patrick's period, summer, and December weekends. January, February, and mid-November usually give you a better chance of seeing lower fares, especially if you can depart on Tuesday or Wednesday and avoid the busiest Friday-to-Sunday patterns. Shoulder-season trips are often the sweet spot on this classic city-break route: you still get a strong travel experience in Dublin, but airlines are not dealing with the same pressure they see during bank holidays, school breaks, or sold-out weekend peaks.

For this route, compare a mix of budget and full-service carriers rather than assuming one airline always wins on value.

• Ryanair: often one of the lowest headline fares if you can travel light.
• easyJet: often competitive on short-haul European routes with solid schedule choice.
• Lufthansa: a strong choice when schedule flexibility matters more than the lowest base fare.
• TAP Air Portugal: frequently competitive on Portugal routes and well-timed European departures.
• Aer Lingus: useful for Ireland-linked schedules and city-break timing.

Headline round-trip fares on this route often start around EUR 74 to EUR 119 in quieter periods. A more typical booking window lands closer to EUR 174 to EUR 239, while peak travel dates can push pricing toward EUR 302 to EUR 412 or higher. Prices change with school holidays, event weekends, and how many travelers are chasing the same nonstop times. On short-haul Europe trips, baggage, seat selection, and airport-transfer costs can change the real total more than many travelers expect, so always compare like-for-like fares.

On this route, airport choice can save money only if the ground transfer still makes sense for your trip. Start with Humberto Delgado Airport on the Lisbon side and Dublin Airport on the Dublin side, then widen the search if the fare difference is meaningful.

• Origin side: Porto (OPO) if an open-jaw Portugal trip fits your plans better
• Origin side: Faro (FAO) if you are heading straight to the Algarve after landing
• Destination side: Cork (ORK) if you are planning an open-jaw trip through southern Ireland
• Destination side: Shannon (SNN) when west-coast Ireland is the main goal

Dublin is compact, lively, and easy to combine with a broader Ireland trip, whether you are after pub culture, coastal walks, or a quick weekend escape. If you are still planning the rest of the trip, see our Dublin destination guide for more ideas before you book.
