297

Thinking about a trip to Dublin? From the historic streets of Temple Bar to the rolling green landscapes just outside the city, Dublin is a perfect blend of history, charm, and lively culture. I’ve visited twice over the years, so I know a few tricks for getting there smoothly and affordably.

For this guide, I’ve selected the 10 best airlines to fly to Dublin in 2025. This is based on data consolidated from over 100 airports across the US and Europe. These airlines offer great routes, affordable fares, and comfort, making it easier than ever to reach Dublin Airport (DUB), Ireland’s main international gateway. With some insider tips included to help you save on your journey, here’s how to kick off your Irish adventure in the best way possible!

Quick tip to find cheap flights to Dublin

Looking for cheap flights to Dublin right now? Before diving into all the airlines that fly to Dublin, I first want to share a quick tip on how to save money on airfare.

For the past three years, I’ve used Scott’s Cheap Flights (now called Going) to get amazing flight deals. All you have to do is enter your home airport and where you want to go, and from there, they’ll send you mistake fares and other ridiculously cheap flight deals. And the coolest part? It’s 100% FREE! In 2024, I’ve saved thousands of dollars from their email alerts. This includes most recently, a $432 roundtrip fare from Boston to Dublin.

There’s a free and a premium version – the free one has pretty much everything you’ll need. Though if you’re like me and travel a lot every year, it’s worth upgrading to the paid version for $49 per year. In my experience, you’ll get your money back after finding just one discounted flight! As such, I recommend signing up for the free trial (you can cancel at any time) to try it for yourself. And if you like it, be sure to use my coupon code JON20 to save 20%!

Now without further ado, here are the best Dublin flights in 2025.

1. 🇮🇪 Aer Lingus

• 🧠 Pro Tip: Book their business class for much lower prices than comparable transatlantic premium cabins

Aer Lingus isn’t just Ireland’s flag carrier, they’re your first taste of Irish hospitality before you even step foot on the Emerald Isle. They’ve been busy expanding their US network, now flying directly to Dublin from cities across America including Boston, New York, Chicago, and yes, even from the West Coast.

Their Business Class won’t empty your savings account like some other transatlantic options, but still delivers the essentials that actually matter: fully-flat beds, proper multi-course meals featuring Irish specialties, and genuinely friendly service without any of the stuffiness. The cabin crews strike that perfect balance of attentive without hovering, creating a relaxed vibe that feels distinctly Irish.

The signature green uniforms and shamrock logo aren’t just for show, Aer Lingus really does bring authentic Irish charm to the skies. You might catch traditional Irish music during boarding, spot local ingredients on the menu, or chat with crew members who are happy to recommend their favorite Dublin pubs and hidden gems.

Their AerClub program uses Avios points but with way smaller fees than you’ll face with British Airways.

Ryanair is the airline Europeans love to complain about but can’t stop flying, and for good reason: nobody connects you to Dublin for less. While they don’t cross the Atlantic, they’re essential for travelers already in Europe or planning multi-city European trips with Dublin on the itinerary.

Their basic Economy experience is exactly that: basic. You’re paying for a seat that goes from A to B, with everything else considered extra. The bright blue cabins have non-reclining seats and limited legroom, but for the typical 1-2 hour flights to Dublin from most European cities, it’s perfectly fine. Their newer Boeing 737s actually offer slightly improved comfort over their older fleet.

What makes Ryanair special is their massive network. They fly to Dublin (DUB) from over 90 European destinations, often with multiple flights daily. Just scored a cheap flight to London or Paris? You can hop over to Dublin for a weekend for less than the cost of a nice dinner. Their frequency also means flexibility, with morning, afternoon and evening options on popular routes.

The secret to Ryanair success? Know their fee structure and play by their rules. Book through their app for the best prices, pay only for what you need, check in online religiously, and make sure your bag fits their exact dimensions. Master these basics and you’ll be flying to Dublin alongside savvy Europeans who’ve turned budget travel into an art form.

Their Business Class on the Dublin route has gotten a serious upgrade in recent years. You’ll find fully flat beds with direct aisle access on most flights, quality bedding from Casper, and a dining experience that’s surprisingly good for an American carrier.

The bedding comes from Westin hotels, the food is surprisingly edible, and the service hits this perfect balance where flight attendants are there when you need something but not hovering every five minutes asking if you’re enjoying your nuts.

What really sets Delta apart is how they handle things when stuff goes sideways. Weather in New York? Mechanical issue? Their proactive rebooking system often has a solution ready before you even realize there’s a problem. Their Dublin-bound fleet is newer than most competitors, with modern amenities like actually usable Wi-Fi and power at every seat, even in regular Economy.

Don’t expect fancy business class seats here. Vueling is proudly all-economy, with the same seats for everyone but different service bundles. Their cabins are bright and cheerful with distinctly Mediterranean energy, and the primarily Spanish crew brings a refreshing warmth compared to some of the more robotic service on legacy carriers.

What makes Vueling perfect for Dublin trips is how they’ve positioned themselves as the ideal connection option for travelers coming from the US via Spain. Scored an amazing deal to Barcelona or Madrid? Vueling will get you to Dublin for less than the cost of a nice dinner.

The planes are whisper-quiet with huge windows, making the flight experience genuinely pleasant rather than something to endure.

The PINS loyalty program isn’t the most generous, but their frequent sales more than make up for it. They’re often the first to announce major discounts for the following season, letting you lock in Dublin trips for absurdly low prices if you can plan ahead.

However, it’s important to be mindful of their strict baggage policies and fees for additional services. Aer Lingus, on the other hand, although more expensive, offers a more comprehensive service. This includes in-flight entertainment, meals on long-haul flights, and a more generous baggage allowance.

Which airports fly nonstop to Dublin from the US?

These cost-saving strategies are passed on to passengers in the form of cheap fares.

What is the best time of year to visit Dublin, Ireland?

The best time of year to visit Dublin depends on what you’re seeking. May through June or September through October are ideal for milder weather and fewer tourists. For those willing to brave chillier temperatures and want to experience Dublin’s festive side, December is magical with its Christmas markets and lights.

How far is Dublin Airport from Dublin City Center?

Dublin Airport is conveniently located approximately 10 kilometers (6 miles) north of Dublin City Center. There are several transportation options available for travelers to reach the city center from the airport:

• Bus Services: Various bus services operate between the airport and different locations in Dublin. The Airlink Express provides fast and frequent service, connecting the airport with many of Dublin’s main attractions and hotspots.

Yes, Dublin Airport is one of the few airports outside North America that offers U.S. Preclearance facilities, which encompasses procedures similar to TSA PreCheck. This service is available at the U.S. Preclearance (USCBP) facility in Terminal 2. The significant advantage of this facility is that U.S.-bound passengers can complete all U.S. immigration, customs, and agriculture inspections at Dublin Airport before departure. After clearing U.S. Preclearance, passengers arriving in the U.S. are treated as domestic arrivals. This means they can avoid immigration queues upon arrival, collect their bags, and continue with their journey. This is particularly beneficial for passengers with onward connections in the U.S., as their baggage is checked through to their final destination.
