You're standing in the middle of Liverpool John Lennon Airport (LJLA), and honestly, it feels like a cheat code. Most people are busy fighting the crowds at Manchester or London, but if you're looking for Liverpool to Dublin flights, you've basically found the shortest, most efficient international hop in the British Isles. It is a puddle-jump. You take off, the crew barely has time to sell you a scratchcard or a lukewarm ham and cheese panini, and then you’re descending over the Irish Sea into Dublin Airport. It’s faster than some commutes on the Merseyrail.
Why does this route stay so busy? Simple. It connects two cities that are basically cousins. You’ve got the shared maritime history, the accents that share a weirdly similar lilt, and a deep-seated love for football and Guinness. But booking these flights isn't just about showing up. If you don't know the rhythm of the airlines or how the Dublin North Terminal works, you’re going to end up paying double for a flight that should cost less than a fancy steak dinner.
The airline duopoly on Liverpool to Dublin flights
Right now, the route is dominated by the big players. You’ve mostly got Ryanair. They own this space. They’ve been flying out of Speke for decades, and for many, "Liverpool to Dublin flights" is synonymous with that blue and yellow livery. Sometimes you’ll see Aer Lingus Regional (operated by Emerald Airlines) dipping in and out or codesharing, but Ryanair is the workhorse here.
It’s a 40-minute flight. Seriously. By the time the pilot reaches cruising altitude and the "fasten seatbelt" sign pings off, you’re already looking at the Dublin coastline. Because it’s such a short distance—roughly 140 miles—the aircraft don’t even need much fuel, which keeps the base fares ridiculously low. I’ve seen tickets for £12.99. That’s cheaper than a taxi from the airport to Liverpool city centre. But—and this is a big "but"—those low fares are a trap if you aren't careful with the luggage rules. Ryanair changed their cabin bag policy years ago, and people still get caught out at the gate, paying £45 because their backpack is three centimetres too wide.
Timing the Irish Sea crossing
Don’t just book the first thing you see. Tuesday and Wednesday are the sweet spots. If you try to fly on a Friday evening, you’re competing with every stag do and hen party in the North West. The atmosphere on those Friday night flights is... lively. If you want peace, go for the 6:30 AM departure. It’s brutal on the sleep schedule, but the airport is quieter, and you’re in Dublin City Centre by 8:30 AM, just in time for a full Irish breakfast.

The wind matters too. The Irish Sea can be a bit choppy. On a clear day, the views are stunning—you can see the Isle of Man sitting right there in the middle—but when the Atlantic gales hit, those smaller 737s can feel a bit "bouncy." It’s nothing to worry about, the pilots do this four times a day, but it’s worth noting if you’re a nervous flyer. Dublin Airport (DUB) is also notorious for its "long walks." If you land at Pier 1, be prepared to get your steps in. It’s basically a marathon to get to passport control.
The Liverpool John Lennon advantage
Why choose Liverpool over Manchester?
Ease.
Manchester Airport is a behemoth. It’s sprawling, confusing, and the security lines can be legendary for all the wrong reasons. Liverpool John Lennon is human-sized. You can get from the car park to the gate in twenty minutes if the gods of security are smiling on you. There’s a statue of John Lennon, a few shops, and a decent pub. It’s manageable.
- Parking: Cheaper than Manchester if you book "Long Stay" in advance.
- Public Transport: The 500 Airport Express bus from Liverpool Lime Street is reliable.
- Security: Generally faster, though they’ve recently updated their scanners, so you don't always have to take your liquids out now—but check the signs, because they’re still rolling it out.
Navigating Dublin Airport once you land
Dublin Airport is divided into Terminal 1 and Terminal 2. Most Liverpool to Dublin flights land at Terminal 1. It’s the older, busier terminal. Once you clear the e-gates (if you have a biometric passport, use them, they save a lifetime), you have to figure out how to get to the city.
There is no train.
I’ll repeat that because it catches people out every single time. Dublin Airport does not have a rail link. You have three choices:

- Aircoach: The blue buses. They’re comfortable, have Wi-Fi, and go straight to O’Connell Street or Leopardstown.
- Dublin Express: Similar to Aircoach, often slightly cheaper if you book online.
- The 16 or 41 Bus: These are the regular city buses. They’re cheap (about €2 with a Leap Card), but they stop everywhere. Only take these if you aren't in a rush and want to save five Euro.
- Taxis: Expect to pay about €30–€40 to get to the city centre. If there are four of you, it’s actually cheaper than the bus.
The hidden costs of "Cheap" flights
People get obsessed with the base fare. "Look, it's only £10!"
Then they add a 20kg bag. Then they pick a seat. Then they buy insurance. Suddenly, your Liverpool to Dublin flights cost £90. If you are just going for a weekend, fit everything into a "personal item" bag that fits under the seat. It’s a 48-hour trip; you don’t need four pairs of shoes. Also, Dublin is expensive. It is one of the priciest cities in Europe for a pint or a hotel room. Saving money on the flight is basically mandatory so you can afford a round of drinks in Temple Bar—though savvy locals will tell you to avoid Temple Bar and head to Smithfield or Rathmines instead.
Why the "Common Travel Area" makes this easy
One of the best things about this specific route is the Common Travel Area (CTA). Because you’re moving between the UK and Ireland, the rules are different than flying to France or Spain. If you’re a British or Irish citizen, you don't technically need a passport to enter Ireland, but—and this is a massive caveat—the airlines require photo ID. Ryanair specifically is very strict; they almost always want a passport. Don't be the person trying to argue with a gate agent about the CTA rules while holding a library card. Just bring your passport. It makes life easier.
The lack of intense customs checks for most passengers means you can usually clear the airport and be on a bus within 30 minutes of touchdown. It’s a level of convenience that's hard to find on other international routes.

First, check the flight prices using a meta-search tool, but always, always finish the booking on the official airline website. Third-party sites are a nightmare if the flight gets cancelled. Second, if you’re flying for a football match—either Liverpool/Everton fans coming from Ireland or Scousers heading to Dublin for a weekend—book at least three months in advance. Prices spike massively on match days.
Your pre-flight checklist:
- Download the Leap Top-Up App: This lets you use your phone to pay for buses and trams (the Luas) in Dublin. It’s much cheaper than cash.
- Check the Terminal: You're almost certainly Terminal 1, but check your boarding pass.
- Weight your bag: Ryanair’s scales at Liverpool are notoriously unforgiving.
- Pre-book the 500 bus: If you’re coming from Liverpool city centre, it’s the most reliable way to get to the airport.
The beauty of the Liverpool to Dublin connection isn't just the destination; it’s the fact that you can leave your house at 5:00 AM and be sitting in a Dublin cafe with a coffee by 8:30 AM. It’s a bridge across the water that has defined the culture of both cities for centuries. Whether you're going for the Guinness Storehouse, a gig at the 3Arena, or just to wander around Trinity College, the flight is the easiest part of the journey. Keep your ID handy, pack light, and enjoy the view of the Welsh coast as you climb out over the Mersey. It never gets old.
