13 Cheapest Places to Fly From Dublin Right Now (2026 Guide)

534

Scoring a cheap flight from Dublin isn’t just luck…it is a math problem, and I’ve solved it. I’ve had clients fly out of Dublin Airport (DUB) countless times (I’ve visited twice, myself). And I know that while it’s a gateway to the world, it can also be a budget trap if you book the wrong routes. For this 2026 update, my team and I spent hours manually analyzing airfare data for 150+ destinations to uncover the absolute best deals right now.

The result? I found that while flight prices across Europe have risen by roughly 15% this year, Dublin remains a “golden hub” for low-cost carriers. I found direct flights to the UK for less than the price of a taxi to the airport, and sunny Mediterranean destinations for under €40.

Whether you’re craving sunny beaches, cultural hotspots, or bucket-list adventures, my guide breaks down the cheapest places to fly from Dublin based on real-time 2026 data.

How I Created This List (My 2026 Methodology)

I stress-tested these routes to ensure they are viable for real travelers. Here is the specific criteria I used to rank these destinations:

• The “3-Month” Rule: I analyzed flight prices for three distinct booking windows: 3 weeks out (last minute), 3 months out (standard planner), and 6 months out (early bird). To make this list, a destination had to show low prices in at least two of these windows.
• Direct Flights Only: Cheap flights aren’t worth it if you have a 12-hour layover. Every destination on this list offers a non-stop route from Dublin (DUB).
• The “Ryanair Reality” Check: The prices listed below are “seat-only” fares (the absolute lowest possible price). I have noted where upgrading for a carry-on bag might double the cost, so you have realistic expectations.
• Tools Used: I cross-referenced data using Google Flights Explore, Skyscanner, and Going.com (formerly Scott’s Cheap Flights) to verify these fares exist for the 2026 travel calendar.

Flying from Dublin in 2026: What You Need to Know

Before you book, you need to know that Dublin Airport (DUB) has undergone significant changes in the last 12 months. If you haven’t flown in a while here is the “insider” briefing on what to expect:

1. The “Passenger Cap” Squeeze (And Why You Must Book Early)

The biggest topic in Irish aviation right now is the 32 million passenger cap. Because the airport is operating near its legal capacity limit, airlines like Ryanair and Aer Lingus have been unable to add as many extra seats as they want for the peak summer season.

• What this means for you: The days of grabbing a €30 flight to Spain two weeks before departure are largely paused for 2026. With supply capped and demand high, last-minute fares are spiking faster than usual.
• My Advice: For Summer 2026 travel, try to book at least 4 months in advance. If you see a good fare, do not “wait and see”—it will likely disappear.

2. New Direct Routes for 2026

Despite the cap, airlines have shuffled their slots to launch some exciting new direct connections this year. If you want to go somewhere new without a layover, look at these just-launched routes:

• Aer Lingus: Launching direct flights to Nashville (BNA), Oslo (OSL) starting May 1, Asturias (OVD) starting May 5, and Montpellier (MPL) starting May 19.
• Transatlantic: The new Dublin to Pittsburgh route (starting May 25) is a game-changer for getting to the US Midwest, and WestJet has revived the handy link to St. John’s, Canada.
• Gulf Carriers: Emirates and Etihad have increased frequencies, making Dublin a better-than-ever hub for one-stop flights to Asia and Australia.

3. Security is Finally Fast (The 100ml Rule is Gone)

Good news: Dublin Airport has fully rolled out the new C3 scanners in both terminals.

• The Upgrade: You can now bring liquids, gels, and aerosols in containers of up to 2 Litres in your hand luggage. You also no longer need to remove laptops or tablets from your bag.
• The Catch: While leaving Dublin is a breeze, many airports you are flying back from (like many in the UK and smaller EU spots) may still have the old scanners. I still travel with 100ml toiletries just so I don’t get caught out on the return leg.

4. US Pre-Clearance is Still a Superpower

If you are flying to the US (New York, Boston, Chicago, etc.), remember that Dublin is one of the few airports in the world with US Pre-Clearance. You go through US immigration in Dublin before you board. For me, this has always been such a game changer!

• The Benefit: When you land in the USA, you walk off the plane like a domestic passenger—no lining up at JFK for 2 hours. It is easily worth the extra price of a direct flight from DUB versus a cheaper layover in London or Paris.

Now, here are all the cheapest places to fly from Dublin right now in 2026 and 2027.

1. Dublin to London (€25 roundtrip)

London still tops the charts as the absolute cheapest flight from Dublin in 2026. Ryanair flies this route multiple times daily starting at just €25 roundtrip, with Aer Lingus and British Airways offering slightly pricier options around €65-100 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 €35. 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 (€30 roundtrip)

Edinburgh flights from Dublin are ridiculously cheap with Ryanair charging around €30 roundtrip and Aer Lingus at about €65 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, 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 (€45 roundtrip)

Barcelona flights remain very affordable, with Ryanair offering roundtrips from just €45 and one-ways starting at €20. Vueling and Aer Lingus also fly this route, typically costing around €95-105 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 €5. Pro tip: book Ryanair but pay extra for seat selection – their random seating can be brutal on longer flights like this.

4. Dublin to Berlin (€55 roundtrip)

Berlin flights typically run €40-65 one-way with Ryanair being your cheapest bet at around €55 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 (€70 roundtrip)

Warsaw flights on Ryanair start around €70 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 (€75 roundtrip)

Brussels flights typically cost around €75 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 (€80 roundtrip)

Lisbon flights run about €80 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.

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 €11. Pro tip: the Beauvais shuttle bus is included in some Ryanair fares, so check before you book.

9. Dublin to Milan (€70 roundtrip)

Milan flights cost around €70 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 (€100 roundtrip)

Budapest flights run around €100-115 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 (€115 roundtrip)

Prague flights cost around €115-125 roundtrip with Ryanair offering the lowest fares to Václav Havel Airport. Aer Lingus also flies this route with better timing but higher prices around €140. 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 (€65 roundtrip)

Amsterdam flights run about €65 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 €5. Bike rental is essential for the full experience.

13. Dublin to Madrid (€70 roundtrip)

Madrid flights cost around €70 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 €5. I love how late everything happens in Madrid – dinner at 10pm feels early, and the city really comes alive after midnight.
