    Flights from Singapore (SIN) to London (LHR)

    Flight route information

    Cathay Pacific offers flights to London Heathrow Airport (LHR) from Singapore Changi International Airport (SIN) with a layover in Hong Kong.

    Flights from SIN to LHR take around 18 hours 45 minutes, including the layover, and bring you to Terminal 2 at London Heathrow Airport.

    Upon your arrival in London

    Located in the outer reaches of London’s underground rail network, Heathrow Airport is well-connected to the city centre, taking just under an hour to reach downtown. The Heathrow Express train also departs from the airport and takes 15-20 minutes to arrive at London Paddington station, while taxis can take you to where you need to be in around 30 minutes.

    A brief introduction to London

    Ancient history and modern attractions await you in London - the political and cultural heart of the United Kingdom. Here, you will find world class galleries, iconic architecture, and a wide range of superb restaurants and authentic pubs.

    Start your trip by exploring London’s vast heritage, which is best experienced at the British Museum. This enormous museum boasts over 8 million objects and artefacts from around the world, most of which were acquired during the height of the British Empire. London also has some of the world’s most renowned galleries, including the National Portrait Gallery, Tate Modern, and Victoria & Albert Museum.

    For a look into London’s history, be sure to visit the city’s most famous historical buildings, such as Big Ben, Westminster Abbey, the Tower of London, and Baroque St Paul’s Cathedral. London’s modern skyscrapers are equally as magnificent - we recommend visiting The Shard and The Gherkin.

    Tucked away from the tourism and shopping hotspots of Piccadilly and Oxford Circus, the glamorous neighbourhood of Soho is an excellent place to dine. Be sure to enjoy a meal at one of the many international restaurants and enjoy a traditional British pint from one of the numerous local pubs.
