Flying from Dublin to Lisbon
Dublin to Lisbon is one of the more straightforward routes out of Ireland — a direct flight covering roughly 1,850 kilometres that puts you on the Atlantic coast of Portugal in under three hours. Nonstop flights from Dublin Airport (DUB) land at Lisbon Humberto Delgado Airport (LIS), and with departure times spread across the day, it's genuinely easy to fly out in the morning and be sitting in Alfama with a glass of wine by early afternoon. The route is well-served enough that you're rarely stuck with awkward timings or a single overpriced option.
For nonstop flights, expect a block time of around 2 hours 45 minutes to 3 hours depending on the airline and wind conditions. Connecting itineraries via Amsterdam, London, Madrid, or Frankfurt are also available if you're flexible or chasing a specific fare, but with direct flights starting as low as €20 on Ryanair, there's rarely a compelling reason to add a layover to this journey.
Airlines on This Route
Three carriers operate nonstop flights from Dublin to Lisbon: Ryanair, Aer Lingus, and TAP Air Portugal. Between them they cover the route comprehensively — Ryanair runs the most frequencies at around 16 flights per week, TAP Air Portugal operates roughly 14 weekly departures, and Aer Lingus offers about 6 per week. Ryanair departs from Terminal 1 at Dublin Airport, while Aer Lingus and TAP use Terminal 2.
If you want the cheapest possible seat and you're travelling light, Ryanair is the obvious choice — just read the baggage rules carefully before you book. TAP Air Portugal is worth considering if you're connecting onward into Brazil or elsewhere in the TAP network, and their business class product on this route is decent for a short-haul flight. Aer Lingus sits in the middle ground: more comfortable than Ryanair, cheaper than you'd expect for a legacy carrier. For connecting flights, KLM, British Airways, Iberia, Lufthansa, Air France, and Vueling all offer one-stop options via their respective hubs.

Best Time to Book Dublin to Lisbon Flights
March is consistently the cheapest month to fly from Dublin to Lisbon, with average fares often sitting between €100 and €200 return, and occasional deals dipping below that. January and February are similarly quiet and affordable, though Lisbon weather in midwinter is mild rather than warm. The shoulder seasons of May and October offer an excellent balance — fares are reasonable (often €49–€77 one-way), the city is less crowded than summer, and Lisbon's climate is genuinely pleasant. September is another strong option: summer crowds thin out but the weather stays warm and the Atlantic is still swimmable.
Peak season runs from late June through August. Lisbon is extremely popular in summer and Dublin to Lisbon flight prices reflect that — fares can double or more compared to shoulder season. If you're set on travelling in July or August, book at least 3 to 4 months ahead. Easter week and school holidays in October also see price bumps worth avoiding if you have flexibility.

Lisbon Humberto Delgado Airport (LIS) sits just 7 kilometres northeast of the city centre — one of the more conveniently located airports in Europe.

Getting into central Lisbon is straightforward: the Metro (Red Line) runs directly from the airport to Alameda, Marquês de Pombal, and Baixa-Chiado, with a journey time of around 20 to 25 minutes and a fare of approximately €1.50 plus a rechargeable card fee.
