Cheap Flights from Lisbon to Dublin

Looking for cheap flights from Lisbon to Dublin? Because this market appeals to both city-break travelers and people with fixed plans, prices can shift fast between midweek and peak departures. Dublin is especially appealing if you want a classic city-break trip without spending hours piecing together separate airline searches. The search form above removes the first step: Lisbon and Dublin are already set, leaving you free to compare schedules, airlines, and nearby airports straight away. That makes it easier to spot whether midweek departures, a different return day, or a nearby airport creates the best-value result before fares climb. It also helps you judge whether paying more for a direct flight is worth it, or if a short connection keeps the overall trip better value.

Flight Distance and Duration

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.

Cheapest Time to Fly from Lisbon to Dublin

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.

Best Airlines for This Route

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.

Average Flight Prices

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.
