Dublin, Ireland’s vibrant capital, is a city that draws millions of visitors every year with its mix of history, culture, and lively pubs. But if there’s one challenge most travelers face, it’s finding affordable flights to Dublin Airport (DUB)—the country’s busiest international hub.
With airfare often being the most expensive part of a trip, learning how to secure cheaper tickets can make your Irish adventure much more budget-friendly. In this article, I’ll share research-backed strategies, first-hand travel experiences, and expert advice to help you find cheap flights to Dublin without the stress.
Why Finding Affordable Flights Matters Today
Flights can easily eat up 30–40% of a traveler’s total budget, especially when flying internationally. With airfare prices fluctuating constantly due to demand, fuel costs, and seasonal peaks, it’s no surprise that savvy travelers look for ways to save.
Personally, on my last trip to Dublin, I managed to save nearly €200 on my ticket by booking strategically—flying mid-week, using price alerts, and comparing multiple booking platforms. Small changes in your approach can lead to significant savings.
Best Strategies to Find Cheap Flights to Dublin
1. Be Flexible with Dates
Airfare to Dublin varies greatly depending on the time of year:
- High Season (June–August): Most expensive due to summer holidays.
- Shoulder Season (April–May, September–October): Cheaper with mild weather.
- Low Season (November–March): Best deals, though weather is colder.
👉 Tip: Flying mid-week (Tuesday or Wednesday) can often be €50–€100 cheaper than weekend departures.
2. Use Reliable Flight Search Engines
Not all booking sites show the same fares. To find the cheapest options, I recommend:
- Google Flights – Great for comparing flexible dates.
- Skyscanner – Best for exploring “cheapest month” and “everywhere” options.
- Momondo – Often finds hidden deals not listed elsewhere.
From experience, I’ve noticed that Skyscanner tends to highlight budget airlines flying to Dublin, while Google Flights is better for major carriers like Aer Lingus, Delta, or United.
3. Set Fare Alerts
Airline ticket prices can change up to 10 times in a single day. Setting alerts ensures you grab a deal before it’s gone. Both Skyscanner and Kayak allow you to track flights and get notified when prices drop.
4. Consider Nearby Airports
While Dublin is the main hub, sometimes flying into Shannon (SNN) or Cork (ORK) can be cheaper, especially from the U.S. and the UK. You can then take a bus or train to Dublin at a fraction of the cost.
5. Book at the Right Time
Studies by CheapAir.com suggest the “prime booking window” for international flights is 2–6 months in advance.
- Booking too early (9–12 months) often means higher prices.
- Booking too late (less than 2 weeks before) means paying a premium.
6. Use Budget Airlines (But Read the Fine Print)
Carriers like Ryanair, Aer Lingus, and Norwegian offer competitive fares to Dublin. However, watch out for extra fees:
- Checked bags
- Seat selection
- Food onboard
I once flew from London to Dublin for just €19.99, but ended up paying an extra €40 for luggage. Always calculate the total cost.
7. Leverage Airline Rewards and Credit Card Points
If you travel often, consider:
- Aer Lingus AerClub (Avios points)
- Credit cards like Chase Sapphire Preferred or American Express Gold, which transfer points to airlines serving Dublin.
On one trip, I booked a one-way flight from New York to Dublin for just $120 by redeeming Avios points.
Common Mistakes to Avoid
- Only checking one website – Always compare at least three.
- Ignoring layovers – Direct flights are faster but not always cheaper.
- Forgetting baggage rules – Budget flights often look cheaper but cost more once fees are added.
- Booking on weekends – Prices are usually higher on Fridays and Sundays.

Final Thoughts
Finding cheap flights to Dublin isn’t about luck—it’s about strategy. By being flexible with dates, comparing multiple booking sites, considering nearby airports, and tracking fares, you can save hundreds on your trip.
From personal experience, booking in the shoulder season (spring or fall) offers the best mix of affordability and good weather. And remember, the cheapest flight isn’t always the best—factor in baggage fees, convenience, and overall travel time.
