We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.
Airlines on this route
Non-stop (about 2¾ hours):
- Ryanair — the most frequent operator and usually a competitive headline fare; add a bag and seat if you need them.
- TAP Air Portugal — the flag carrier, with a full-service product and easy onward connections to Porto, Madeira and Brazil.
- Aer Lingus — several flights a week with checked baggage on most fares and a more generous cabin allowance.
All three fly the identical non-stop route, so choosing between them is about price and what’s included rather than speed. One-stop itineraries via London or a European hub exist but almost never beat the direct fares, so there’s rarely a reason to add a connection.
When to book & how to save
- Book 6–10 weeks ahead for off-peak dates; for July, August or Easter, book 3–4 months out.
- Target the shoulder seasons: late September, October and the winter weeks are noticeably cheaper, and Lisbon’s mild weather makes them a smart time to visit.
- Compare the all-in price: a Ryanair fare plus a checked bag and seat can cost more than a TAP or Aer Lingus ticket that already includes them.
- Fly cabin-only on Ryanair or TAP’s light fare for the cheapest returns if you can pack light.
- Set a price alert: short-haul fares to Lisbon move quickly and the best sale fares don’t last.
Arriving in Lisbon
Flights land at Humberto Delgado Airport (LIS), unusually close to the city at about 7 km north of the centre. The easiest way in is the Metro red line (Aeroporto station) to the centre in around 20 minutes for a couple of euro plus the reusable card, or the Carris 744/783 buses. A taxi or ride-hail to the city centre is quick and typically costs about €15–€20. Given how near the airport is, transfers are cheap and fast whichever option you pick.
Frequently asked questions
How long is the flight from Dublin to Lisbon?
The non-stop flight takes about 2 hours 45 minutes to 2 hours 55 minutes. Times vary a little with wind and routing, and the northbound return to Dublin can run slightly longer. All three airlines fly it direct, so there’s no need to connect.
Are there direct flights from Dublin to Lisbon?
Yes. Aer Lingus, Ryanair and TAP Air Portugal all fly non-stop between Dublin and Lisbon, with close to 30 departures a week combined. Because the direct fares are so competitive, one-stop routings via London or another hub rarely save money.
How much does it cost to fly from Dublin to Lisbon?
A typical economy return runs about €80–€250 depending on the season. The cheapest cabin-only fares on Ryanair or TAP can dip to around €55–€82 return off-peak, while summer peak fares and bag-included tickets sit toward the top of the range.
What is the cheapest month to fly from Dublin to Lisbon?
January, February and November are usually the cheapest months to fly. Avoid July and August, the busiest and priciest months; late September and October offer warm weather at much better prices.
Which airlines fly from Dublin to Lisbon?
Ryanair flies the most frequent service at the lowest headline fares, TAP Air Portugal offers a full-service seat with easy connections onward within Portugal and to Brazil, and Aer Lingus flies several times a week with checked baggage on most fares. All three operate the identical non-stop route.
Which airport do I fly into in Lisbon?
You’ll land at Humberto Delgado Airport (LIS), Lisbon’s main airport, only about 7 km from the centre. The Metro red line links it to the city in around 20 minutes, and a taxi to the centre is quick and inexpensive — one of the closest airport-to-city transfers in Europe.
How far in advance should I book Dublin to Lisbon flights?
Aim to book 6 to 10 weeks ahead for off-peak travel, and 3 to 4 months ahead for summer or Easter. Fares to Lisbon climb as seats sell, especially over the busy spring and autumn city-break weekends, so early booking with a price alert usually wins.
Is it cheaper to fly on weekdays?
Often, yes — midweek departures (Tuesday to Thursday) tend to be a little cheaper than Friday-to-Sunday breaks, and shifting your dates by a day or two save a little on a return. Date flexibility is one of the easiest ways to bring the fare down.
