The cheapest fare in this week's search from Dublin is EUR 15 one way to Barcelona with Ryanair. Our flight-search partner found it on 1 November 2026, for a departure in December 2026. Every fare in this round-up is a cached one-way price for one adult, found on the date shown. None of them is a live price. They will have moved by the time you read this, possibly in your favour.
Below is what turned up for cheap flights from Dublin Airport, which carrier supplied the fares, and how to treat a cached price so it helps you plan rather than setting you up for disappointment.
The fares worth a closer look
Barcelona, EUR 15, found 1 November 2026. This is the headline fare, and the only continental destination on this week's list. It is also the only one for travel in December 2026 rather than November. A winter city break in Barcelona at this sort of price is the classic Dublin low-cost flights story: the seat is cheap, and the real cost depends on what you add to it.
| Destination | Airline | Fare | Travel | Found |
|---|---|---|---|---|
| BCNBarcelona | Ryanair | from 15 EUR | Dec 2026 | found 1 Nov |
| MANManchester | Ryanair | from 16 EUR | Nov 2026 | found 31 Oct |
| STNLondon | Ryanair | from 16 EUR | Nov 2026 | found 1 Nov |
Manchester, EUR 16, found 31 October 2026. A short hop for travel in November 2026. This is the oldest fare in the list, found the day before the other two, so treat it with a little more caution. Manchester is one of the bases Ryanair lists among its hub airports, which helps explain why fares on the route can dip this low.
London, EUR 16, found 1 November 2026. Also for travel in November 2026. The city label says London, but the airport is Stansted, so allow for the onward journey into town when you compare it with other ways of getting there. Stansted is Ryanair's largest base, and Dublin comes next, so this is a route between the airline's two biggest operations.
One detail applies to all of them. The departure month tells you when the fare was available, not that every day in that month costs the same. A price found for one date can sit next to far dearer days either side of it.
One airline has the list to itself
Every fare in this week's list is Ryanair's. That is no great surprise at Dublin. The group is headquartered in Swords, County Dublin, and Dublin is its second-largest base after Stansted.
Ryanair is also big enough to dominate a short list like this. Its group fleet stood at 647 aircraft on 30 June 2026, a figure that counts the whole airline group rather than Ryanair DAC alone (source: Q1 FY27 presentation). The parent company runs five airlines under separate operating certificates: Ryanair DAC, Buzz, Malta Air, Lauda Europe and Ryanair UK. You book through one brand and one website, but the aircraft on your route may belong to any of the five.
The airline is open about shifting capacity between countries depending on airport fees and aviation taxes. That matters for anyone watching fares. Cheap seats tend to appear where an airline has aircraft to fill, and those decisions can change from one season to the next.
A caveat on the list itself: this is not a full survey of every carrier flying from Dublin. It shows the lowest fares our partner had cached when we checked, and on this occasion they all came from one airline.
How to use cached fares
Cached fares are best read as a signal of what is possible on a route in a given month. Used that way, they are genuinely useful. Used as a promise, they will let you down.
- Check the found date. Fares change daily, sometimes hourly. A price found on 31 October 2026 is more likely to have moved than one found on 1 November 2026.
- Search the whole month. If the departure month suits you, try several days. The cheapest date is rarely the one you would have picked.
- Read what the fare covers. Ryanair's basic ticket includes the seat and one small personal bag of up to 40 x 30 x 20 cm, which must fit under the seat in front. A 10 kg overhead-locker bag (55 x 40 x 20 cm) comes with the Priority & 2 Cabin Bags add-on, and 10 kg, 20 kg and 23 kg check-in bags are all sold separately. Seat selection is extra too. These allowances come from Ryanair's help centre, read on 24 October 2026; check your own booking for what your fare includes.
- Have your phone ready. Ryanair withdrew paper boarding passes in November 2025 in favour of digital ones, so plan to carry yours in the app.
- See what actually flies. The Dublin departures board shows the routes in operation, which is a quick way to spot alternatives to the destinations above.

Our take
In our view, this week's list is a fair snapshot of how Dublin works for budget travellers: Ryanair's home turf, with short, busy routes priced to fill seats. The fares are real, but they are the floor, not the typical price.
The Manchester and London fares make the most sense for a light traveller. If an under-seat bag is genuinely enough for a couple of nights, the fare you see is close to what you pay. Barcelona in December is tempting, but a week away usually means a proper bag, and that is where the add-ons start to matter.
Our advice is simple. Use these fares to decide where and when to look, then search properly, price in your bags before you compare, and do not assume the number you saw on a blog will still be there tomorrow.
