Find cheap flights from Dublin to London

Crossing the Irish Sea from Dublin to London offers a seamless transition between two of the most storied capitals in the world. While the departure point is steeped in literary charm and a famously warm spirit, the destination greets visitors with a staggering mix of royal heritage and cutting-edge modernity. Travellers are drawn to the famous skyline, where the Palace of Westminster and Tower Bridge stand as symbols of a history that shaped the globe. Beyond the architectural marvels, the city is a patchwork of distinct boroughs, each offering a different pace of life, from the quiet greenery of Hampstead Heath to the buzzing energy of the West End. Whether you are visiting to explore world-class galleries or to wander through centuries-old markets, there is a constant sense of discovery that makes every trip feel unique.

The journey itself is remarkably efficient, with a typical flight duration of roughly 1 hour and 15 minutes in the air. Because this is one of the busiest international corridors, departures are exceptionally frequent, with dozens of flights leaving throughout the day from Dublin Airport. You can choose to land at several major hubs, including Heathrow Airport, Gatwick Airport, or London City Airport, depending on which part of the city you wish to reach first. If you prefer a quieter experience at the terminal, mid-week travel on a Tuesday or Wednesday often feels less hurried than the busy Monday morning or Friday evening peaks. For those who enjoy crisp weather and festive displays, visiting during the late autumn or the lead-up to the winter holidays provides a particularly atmospheric backdrop for exploring the city’s historic streets.

Dublin Airport acts as the primary international gateway for the region, facilitating a vast number of short-haul hops across the Irish Sea. Passengers can choose from several arrival points depending on their final destination, including London Heathrow, London Gatwick, London Stansted, London Luton, and London City Airport.

Dublin Airport (DUB)

Dublin Airport is situated approximately 10 km north of the city centre and serves as the main hub for the national carrier as well as several low-cost airlines. This major aviation site features two main terminals; Terminal 1 generally handles short-haul European traffic, while Terminal 2 is the base for long-haul operations and specific premium services. The airfield is exceptionally well-connected by a network of express coaches and local buses that run 24-hour services to the heart of the city. Within the departure halls, travellers will find extensive retail areas and lounges that provide a comfortable environment before boarding their 1 hour and 15 minutes flight to the United Kingdom. Over 20 million passengers pass through these gates annually, making it a vital piece of infrastructure for those heading to the various terminals serving the Greater London area.

Flying from Dublin to the capital offers several points of entry, each serving different parts of the city. Most travellers arriving from Dublin Airport will land at Heathrow, Gatwick, or London City, which are the primary hubs for this busy short-haul corridor.

Heathrow (LHR)

As the largest aviation hub in the United Kingdom, Heathrow Airport handles a high volume of daily flights from the Irish capital. Situated roughly 24 km west of the city centre, this facility is known for its extensive connections and links to the Elizabeth Line and the Piccadilly Line. Most major carriers use this site, providing passengers with access to modern terminals and premium lounge facilities.

Gatwick (LGW)

Located south of the city, Gatwick Airport is a popular choice for those seeking both low-cost and full-service options. It is approximately 45 km from central districts but remains highly accessible via the Gatwick Express, which reaches Victoria Station in about 30 minutes. The airfield is divided into two main terminals, both of which offer a wide range of retail and dining experiences.

London City (LCY)

London City Airport is the most central option, located in the heart of the Royal Docks. Because it is situated just 11 km from the financial district, it is favoured by business travellers for its rapid boarding processes and proximity to the Docklands Light Railway. The single-runway site provides a scenic approach over the River Thames.
