Other considerations when finding cheap places to fly from Dublin
To discover the cheapest places to fly from Dublin, I honed in on major airports across Europe, North America, and Asia. While there’s always a chance to stumble upon deals to more distant locales, it’s these regions that frequently offer the most affordable and convenient routes from Dublin.
Keep in mind, flight prices from Dublin can fluctuate significantly throughout the year. For instance, a flight to the Spanish coast might be pricier in the summer months than during autumn or spring. And if Europe’s mainland beckons, aiming for the off-season, generally between November and February, might be your best bet. While the exact fare might shift depending on when you decide to embark, the cheapest destinations from Dublin will largely remain consistent, no matter the time of year.
For the purposes of this article, I’ve omitted nearby destinations. This encompasses cities like Belfast, Glasgow, Liverpool, and Manchester, which indeed offer cheap flights from Dublin, but are also a feasible road trip away. My emphasis was more on cheap flights from DUB to a broad range of destinations, spanning continents.
Whether you’re eyeing local or global destinations, here are the 13 cheapest places to fly from Dublin Airport in 2025.
1. Dublin to London ($20 roundtrip)
London still tops the charts as the absolute cheapest flight from Dublin in 2025. Ryanair flies this route multiple times daily starting at just $20 one-way, with Aer Lingus and British Airways offering slightly pricier options around $70-104 if you want more legroom. I honestly can’t believe how cheap these flights have gotten – you can literally get to London for less than a Dublin taxi ride to the airport.
The best deals happen during January and October when you’ll find roundtrip fares as low as $40. Ryanair flies direct to London Stansted, Gatwick, and Luton airports, while Aer Lingus goes to Heathrow. Book about 27 days in advance for the lowest prices, though I’ve scored last-minute deals that were actually cheaper than the bus. London’s transport system is so good that flying into any of the airports works perfectly fine – the Stansted Express gets you downtown in 45 minutes.
2. Dublin to Edinburgh ($31 roundtrip)
Edinburgh flights from Dublin are ridiculously cheap with Ryanair charging around $29 one-way and Aer Lingus at about $69 roundtrip. Both airlines offer direct flights that take just over an hour, making this one of the best weekend escape deals you’ll find anywhere. I actually prefer flying Aer Lingus on this route because their timing works better if you want to maximize your weekend.
The cheapest month is January (averaging £71), but honestly, Edinburgh in winter is pretty magical with shorter crowds and cozy pub vibes. Spring and early autumn give you the best weather without peak pricing. Edinburgh Airport is super close to the city center – about 20 minutes by tram or bus. Don’t sleep on Edinburgh’s festival season in August, but expect to pay double the usual fare during Fringe Festival time.
3. Dublin to Barcelona ($36 roundtrip)
Barcelona flights have gotten insanely cheap in 2025, with Ryanair offering roundtrips from just $36 and one-ways starting at $15. Vueling and Aer Lingus also fly this route, typically costing around $98-105 roundtrip. The flight time is about 2.5 hours direct, and honestly, these prices make Barcelona more accessible than most domestic destinations.
January is the absolute cheapest month to fly, but I’d actually recommend April-May or September-October when the weather’s perfect and prices are still reasonable. Avoid July-August unless you love crowds and want to pay triple. Barcelona-El Prat Airport connects to the city center via metro in about 30 minutes for €4. Pro tip: book Ryanair but pay extra for seat selection – their random seating can be brutal on longer flights like this.
✈️ My #1 Tip for Cheap Flights:
If you’re not using Going, you’re probably overpaying for flights. I’ve scored roundtrips to Europe for under $300 - and I never would’ve found them on Google Flights.
Their free version is great, but Premium is where the real magic happens. I recommend doing the 14-day free trial. And right now, you can get 25% off Premium or Elite with my code: JON25.
Seriously, it’s the best travel decision I’ve ever made (in 8+ years).

4. Dublin to Berlin ($51 roundtrip)
Berlin flights typically run $41-70 one-way with Ryanair being your cheapest bet at around $51 roundtrip. Aer Lingus costs more but offers better timing and service. The flight takes about 2.5 hours to Berlin Brandenburg Airport, which finally opened properly and actually works well for getting into the city.
I’ve found the best deals during spring and autumn – Berlin in winter can be pretty gray, though the Christmas markets are legitimately awesome. The city’s so affordable once you’re there that spending a bit more on Aer Lingus might be worth it for the extra comfort. Berlin’s public transport is excellent, and honestly, the city has this incredible energy that makes any flight price feel worth it. Book about 6-8 weeks ahead for optimal pricing.

5. Dublin to Warsaw ($69 roundtrip)
Warsaw flights on Ryanair start around $69 roundtrip, making Poland one of the best budget destinations from Dublin. The flight time is roughly 2.5 hours direct to Warsaw Chopin Airport, and trust me, this city is massively underrated. Your money goes so much further in Warsaw than most European capitals.
Spring and early autumn offer the best combination of weather and pricing. Warsaw’s Old Town is absolutely stunning (completely rebuilt after WWII), and the pierogi scene alone justifies the trip. The airport is well-connected to downtown via train in about 20 minutes. I was genuinely surprised by how modern and vibrant Warsaw feels – it’s nothing like the outdated stereotypes you might have heard.

6. Dublin to Brussels ($72 roundtrip)
Brussels flights typically cost around $72 roundtrip with Ryanair and Aer Lingus both serving this route. Flight time is about 1.5 hours to Brussels Airport, which connects to the city center via train in 20 minutes. The chocolate and beer alone make this trip worthwhile, but Brussels actually has way more going on than most people realize.
Late spring and early autumn offer the best weather and reasonable prices. I honestly think Brussels gets overlooked because it’s viewed as just an EU headquarters city, but the comic book murals, amazing food scene, and proximity to other European cities make it a perfect long weekend destination. The Grand-Place at night is absolutely gorgeous, and the waffle situation is legitimately better than anywhere else I’ve been.
7. Dublin to Lisbon ($77 roundtrip)
Lisbon flights run about $77 roundtrip with both Ryanair and Aer Lingus offering direct service. Flight time is around 2.5 hours to Lisbon Airport, and the weather in Portugal is consistently better than Ireland year-round. The flight deals have been consistently good throughout 2025.
Spring and autumn are ideal for weather and pricing, though Lisbon honestly works any time of year. The tram system is iconic (if slow), and the pastéis de nata are genuinely life-changing. I’ve been multiple times and Lisbon has this perfect mix of history, great food, and Atlantic vibes that feels way more affordable than other Western European capitals. The airport train gets you downtown in about 20 minutes.

8. Dublin to Paris ($55 roundtrip)
Paris flights are surprisingly affordable at around $55 roundtrip with Ryanair, though Aer Lingus charges more for Charles de Gaulle instead of Beauvais. If you don’t mind the hour-long bus ride from Beauvais, Ryanair’s deal is unbeatable. Flight time is about 1.5 hours, making this perfect for weekend trips.
Shoulder seasons (April-May, September-October) offer the best value, though Paris is obviously crowded year-round. I actually prefer winter visits when hotel prices drop and the Christmas markets are running. The RER B from Charles de Gaulle takes about 45 minutes to central Paris and costs around €10. Pro tip: the Beauvais shuttle bus is included in some Ryanair fares, so check before you book.

9. Dublin to Milan ($71 roundtrip)
Milan flights cost around $71 roundtrip with Ryanair flying to Milan Bergamo (about an hour from the city) and Aer Lingus serving Malpensa (closer but pricier). Flight time is about 2.5 hours, and honestly, Milan’s fashion scene and aperitivo culture make it worth the splurge.
Spring and autumn are perfect for weather and reasonable prices. Milan during fashion week is insane (and expensive), but the energy is incredible if you can handle crowds. The Duomo is legitimately breathtaking, and the shopping obviously can’t be beat. Malpensa Express gets you downtown in 45 minutes, while Bergamo requires a bus transfer that adds time but saves money.
10. Dublin to Budapest ($104 roundtrip)
Budapest flights run around $104-122 roundtrip with Ryanair offering the best deals to Ferenc Liszt International Airport. Aer Lingus also serves this route at slightly higher prices. Flight time is about 2.5 hours, and Budapest consistently delivers some of the best value in Europe.
May offers the cheapest flights, while August is peak pricing. The thermal baths are absolutely incredible year-round – I actually prefer going in winter when soaking in hot springs feels perfect. Budapest’s ruin bars are legendary, and the architecture along the Danube is spectacular. The airport connects to downtown via train in about 30 minutes. Your money goes ridiculously far here compared to Western European capitals.
11. Dublin to Prague ($118 roundtrip)
Prague flights cost around $118-126 roundtrip with Ryanair offering the lowest fares to Václav Havel Airport. Aer Lingus also flies this route with better timing but higher prices around $144. Flight time is about 2.5 hours, and Prague remains one of Europe’s most stunning cities.
January offers the cheapest flights, while July peaks in price. Prague in winter is magical with Christmas markets and fewer crowds, though spring reveals the city’s full beauty. The beer is ridiculously cheap and good, and the old town feels like a fairy tale. Airport Express buses get you downtown in about 45 minutes for a few euros. I’ve visited multiple times and Prague never gets old – it’s got this perfect mix of history and affordable nightlife.
12. Dublin to Amsterdam ($57 roundtrip)
Amsterdam flights run about $57 roundtrip with Ryanair and Aer Lingus both offering direct service to Schiphol Airport. Flight time is roughly 1.5 hours, making this perfect for quick getaways. Schiphol is one of Europe’s best airports and connects seamlessly to Amsterdam via train.
Spring (tulip season) is obviously peak pricing, but autumn offers great deals with mild weather. The canal ring is UNESCO-protected for good reason, and the museum scene is world-class. I honestly think Amsterdam works any time of year – even winter has its charm with cozy brown cafés. The train from Schiphol takes 15 minutes to Amsterdam Centraal for about €4. Bike rental is essential for the full experience.
13. Dublin to Madrid ($69 roundtrip)
Madrid flights cost around $69 roundtrip with Ryanair serving Madrid-Barajas Airport directly. Aer Lingus also flies this route at competitive prices. Flight time is about 2.5 hours, and Madrid’s art scene and nightlife make it consistently worth visiting.
Spring and fall offer the best weather and reasonable pricing – Madrid in summer can be brutally hot. The Prado and Reina Sofía museums are obviously world-class, but the tapas hopping culture is what really makes the city special. Metro Line 8 connects the airport to downtown in about 30 minutes for €2. I love how late everything happens in Madrid – dinner at 10pm feels early, and the city really comes alive after midnight.
