Cheap Flights from Dublin to Lisbon

November is where this route prices lowest, and the calendar runs through all twelve months, so you can see the dip and pick around it. Fares climb from late spring with the summer school holidays, and June fills Lisbon itself, when street festivals pull crowds into the centre. Christmas, New Year and Easter all price up, as does Dublin around St Patrick's weekend in March. Midweek departures usually sit below the weekend ones, and shoulder months like May, September or October give you mild evenings in Lisbon without peak-season fares. Once a month is fixed, scan the dated prices across it instead of trusting any single day.

The airline mix tilts low-cost: Ryanair, Vueling Airlines, Iberia Express and Transavia France, alongside full-service Aer Lingus, KLM Royal Dutch Airlines and Scandinavian Airlines, with Luxair and Emerald Airlines rounding out the list. Ryanair and Aer Lingus fly the capitals nonstop, while KLM connects through Amsterdam, Luxair through Luxembourg and the Spanish names via Madrid or Barcelona. What the fare includes differs more than the headline suggests: low-cost tickets generally cover a small cabin bag only, with checked bags, seat choice and extras added on top, while full-service fares fold a baggage allowance and seat selection into the price. Compare totals, not sticker prices.

Getting in is the easy part: Lisbon Airport sits close to the city's northern side, and the metro's red line runs from a station at the terminal toward the centre of Lisbon, so the transfer feels like the last leg of the flight rather than a second journey. Buses plug the gaps, and a taxi or ride-hailing app covers the rest, though rush hour slows any road transfer into the centre. Two things to watch: low-cost carriers often use a separate terminal, so confirm where your airline lands before arranging a pickup, and the metro pauses overnight, so a very late arrival means booking a taxi.

Country facts: Wikidata

• Dublin has a single airport, so the real choice at this end is nonstop versus one-stop rather than which terminal.
• Low-cost fares on this route usually cover just a small cabin bag, so check what your ticket includes before adding a checked bag.
• Most European travellers can enter Portugal on a passport or identity card — confirm what your nationality needs.
• Low-cost carriers often land at Lisbon's separate terminal, so check where your airline arrives before a pickup.
• November typically prices lowest here, while summer holidays and Christmas week push fares up.
• Book a connection on two separate tickets and leave a long gap between flights — neither airline rebooks you for the other's delay.
