Cheap flights from Seattle to London

Whether you're heading from Seattle to London for work or a vacation, you're in for a whirlwind of excitement and history. Getting to the Seattle-Tacoma International Airport (SEA) is a breeze thanks to transport options like bus, light rail, taxis or buses. After taking off, you can expect your flight to London Heathrow (LHR) to take approximately nine hours. Once you arrive, you'll have the chance to explore major districts in London like the Covent Garden, Notting Hill and Soho.

Attractions

If you're planning to rent a car while in London, you'll spend some time on the A501, a ring road that encircles the city. Public transport is also plentiful, and you can rely on the ubiquitous double-decker buses, the traditional black cabs, or the train system called the London Overground. Take the chance to tour spectacular landmarks like Buckingham Palace, Westminster Abbey, Big Ben, the London Eye, Trafalgar Square and the British Museum.

Hints and Tips

Keep in mind that when people refer to the City of London, they are referring exclusively to the small inner district taking up just a square mile of land, which is still surrounded by Roman-era walls. The weather in London can be rainy year-round, so packing an umbrella ensures that you can stay dry and spend the day sightseeing.

*Price based on the lowest price found within past 24 hours and based upon one night stay for two adults over the next thirty days. Prices and availability subject to change. Additional terms may apply.
