It is not too difficult to work out why the aviation routes between the UK and Dublin are so well used, given the large number of people born in Ireland who now live in the UK
Dublin has been unveiled as the most popular international destination for UK air travellers in the first six months of 2025.
According to new analysis of Civil Aviation Authority (CAA) data by air passenger rights experts, AirAdvisor, over 4.8 million passengers flew between the UK and the Emerald Isle’s major airport, Dublin Airport, between January and June 2025.
In previous years, Palma De Mallorca in Spain and the Dutch capital Amsterdam claimed the top spot in the frequent flights ranking.
Other destinations that frequently welcome large numbers of UK travellers include Alicante, Malaga, Faro, and Dubai. European capital cities, including Madrid, Paris, and Lisbon, also experience significant traffic to and from the UK.
AirAdvisor CEO Anton Radchenko said: “Ireland is an extremely popular destination for UK travellers due to the two countries’ historic connections. It’s a busy route for holidaymakers between the nations’ major cities and also people visiting family members based either side of the Irish Sea.
“Amsterdam remains a popular city break spot for UK travellers while those looking for year-round sun often opt for destinations like Dubai and Tenerife.”
It is not too difficult to work out why the aviation routes between the UK and Dublin are so well used.
According to the Office for National Statistic’s anual population survey, there were approximately 412,000 people who were born in the Republic of Ireland living in the UK as of June 2021. The number of people of Irish ancestry in the UK is significantly higher, with estimates suggesting around six million people have at least one Irish grandparent.
Many of those people still have connections to the Irish capital, giving them a very good reason to hop on a Ryanair or Aer Lingus flight and head back. It is often cheap. A flight from the UK to Dublin can be booked for as little as £16 next week. Kayak also has rooms for from £37 a night.
For those who don’t have such a connection, there are plenty of reasons to hop on the hour long flight from the UK and visit Dublin.
A trip to the Guinness Storehouse is a must for most visitors — and it absolutely lives up to the hype. Whether you join a guided tour or take your time exploring solo, you’ll get a fascinating look at how the iconic Irish stout is brewed — and of course, there’s a tasting involved.
History enthusiasts will feel right at home at Malahide Castle. Set in picturesque surroundings, the castle invites you to step back in time with guided tours and stories from centuries past. Afterwards, wander through the serene gardens for a relaxing stroll.
Another historic highlight comes in the Book of Kells Exhibition, where you can view one of the most famous illuminated manuscripts in existence.
There are plenty of museums in the city, including:
- Kilmainham Gaol: This former prison offers powerful insights into Ireland’s complex past.
- Dublin Writers Museum: A literary pilgrimage for fans of James Joyce, Oscar Wilde, and other Irish greats.
- The Irish Rock ‘n’ Roll Museum is a treasure trove of memorabilia and a hit with music lovers.
- The Little Museum of Dublin showcases the city’s modern history, with an entire room dedicated to U2.
- The Irish Whiskey Museum, where you can learn all about one of Ireland’s most beloved exports.
