Cheap flights from Washington DC to London

Ronald Reagan Washington National Airport (DCA) is conveniently accessible by car, via the George Washington Memorial Parkway and by Washington Metro trains. A direct flight from Washington, D.C., to London takes approximately eight hours.

England's capital city invites you to explore the rich and complicated heritage of the British Empire. Visit Westminster Abbey to discover a splendid church, which has hosted the coronations and weddings of some of England's most notorious and beloved monarchs. From the Tower of London to Buckingham Palace, there are plenty of historic landmarks in London that will immerse you in English history.

Attractions

The M25 Motorway is a major highway that allows you to conveniently navigate the outskirts of London. Use the North Circular Road to drive through the core of London, and drive over many of the bridges across the River Thames. Whether you take signature double-decker buses or metro trains in The Tube, you can conveniently reach London's top fine arts venues like The National Gallery and Tate Modern.

Hints and Tips

Once you land at London Heathrow Airport (LHR), use the Heathrow Express trains to ride between some of the terminals and make ground transport connections. London has a maritime climate, which means that rain and fog can be expected year-round. If the skies open up to some sunshine, head to Hyde Park and Regent's Park to enjoy some of the city's largest green spaces.
