Find cheap flights from Belfast to London

Travelling from the heart of Northern Ireland to the bustling capital of England offers a seamless transition between two of the most significant urban landscapes in the British Isles. As you leave the maritime charm of Belfast, you are headed toward a global powerhouse defined by centuries of history and a skyline that effortlessly blends the ancient with the avant-garde. London remains a premier destination for those seeking to walk through the corridors of power at the Houses of Parliament, explore the vast collections of the British Museum, or simply soak in the atmosphere of its diverse neighbourhoods. Whether you are visiting for the world-class theatre in the West End, the lush expanses of Hyde Park, or the historic grandeur of Buckingham Palace, the city provides an endless array of cultural and scenic experiences that cater to every type of traveller.

The journey across the Irish Sea is remarkably efficient, making it a popular route for both weekend getaways and professional trips. A direct flight typically lasts about 1 hour and 15 minutes, covering a distance of roughly 525 km. You have plenty of flexibility when planning your departure, as flights leave frequently from both Belfast International Airport and George Best Belfast City Airport. Upon arrival, you may land at various hubs, including Heathrow Airport, Gatwick Airport, London City Airport, or Stansted Airport, all of which offer robust transport links like the Elizabeth Line or the Gatwick Express to reach the city centre. For those looking to enjoy a quieter experience with shorter queues, mid-week departures during the Tuesday or Wednesday morning windows often provide a more relaxed pace. While the city is a year-round destination, visiting during the shoulder seasons of spring and autumn allows you to witness the royal parks in full bloom or rich gold, often with more manageable crowds at the major landmarks.

Belfast is served by two distinct departure points for flights to London. While one sits just minutes from the city centre, the other offers a wider range of low-cost connections from a coastal location. Both hubs provide frequent daily links to various major airports across London.

George Best Belfast City Airport (BHD)

Located just 5 km from the metropolitan centre, this facility is the most convenient option for business travellers and weekend visitors alike. George Best Belfast City Airport operates as a single-terminal hub, allowing for quick transit times from the check-in desks to the departure gates. It primarily hosts full-service carriers and regional airlines, offering multiple hourly rotations to London City Airport and Heathrow Airport.

Belfast International Airport (BFS)

Situated roughly 29 km northwest of the city, this larger site serves as the primary gateway for international and low-cost traffic. Belfast International Airport operates 24-hour service and handles a significant volume of passengers heading toward Gatwick Airport, Luton Airport, and Stansted Airport. Because the airfield occupies a sprawling site in Crumlin, it provides extensive amenities and a high frequency of departures, making it a flexible choice for those prioritising budget-friendly schedules.

Travelling between these two capitals is a seamless experience, with frequent connections departing from both Belfast City Airport and Belfast International Airport. Depending on your chosen airline, you will likely land at Heathrow Airport, Gatwick Airport, or London City Airport. Each destination provides a distinct entry point into the city, catering to different schedules and final destinations.

Heathrow Airport (LHR)

As the UK’s premier aviation hub, London Heathrow Airport handles a high volume of traffic from Northern Ireland. This facility is situated to the west of the city and is renowned for its extensive connectivity, featuring four active terminals and a dedicated underground station. Those arriving here can access central districts via the Elizabeth Line or the Heathrow Express, which reaches Paddington Station in approximately 15 minutes.

Gatwick Airport (LGW)

Located to the south, London Gatwick Airport serves as a vital gateway for both low-cost and flagship carriers. This two-terminal site is linked directly to the national rail network, with the Gatwick Express providing a swift route to Victoria Station. It is an ideal choice for travellers heading towards the South Coast or the southern boroughs.

London City Airport (LCY)

London City Airport offers the most central arrival point, positioned in the heart of the Docklands. Due to its proximity to the financial district, it is a favourite for those on tight schedules. The Docklands Light Railway serves the terminal, offering a short transit time to Canary Wharf.
