Flights to Seattle

A flight from London to Seattle takes just under 10 hours.

It's generally cheaper to fly between October and May, outside of the busier summer months. To find the cheapest flights to Seattle, search our low fare finder.

Most visitors head to Seattle in peak summertime when the weather’s fine and dry, but the hotel prices can be more expensive. You may get better value for money if you travel in spring or autumn – just don’t forget your umbrella.

Although entry prices can add up if you’re visiting the city’s many attractions, Seattle’s proximity to impressive natural wonders means there’s much to enjoy that’s free. There’s no charge to explore the city’s botanical gardens at Washington Park Arboretum, or for picnicking in Carkeek Park’s 220 acres of forest, meadows, wetlands and beaches with priceless views over Puget Sound and the Olympic Mountains. For sky-high city views with a coffee – and crucially, no entrance fees – head to Starbucks on the 40th floor of the Columbia Center.

Once you land at Seattle-Tacoma International Airport, known locally as SeaTac, you’re rewarded with a straightforward journey into the city centre. There are plenty of taxis queueing at the airport, or it’s easy enough to jump onto the Link light rail which reaches downtown Seattle in under 40 minutes. Once you’re in the city, the main attractions are walkable or accessible by the Link light rail, buses or Streetcar trams.

You can also hire a car with British Airways if you want to see more of what Seattle and Washington State has to offer. You’ll receive great benefits, with all mandatory charges included and 24-hour customer support, plus you’ll collect Avios points on every rental.

With lush evergreen forests – the reason it’s named the emerald city – plus picture-perfect peaks, lakes, beaches and a slick cityscape, Seattle’s wholesome good looks are reason enough to make the journey. You’re spoilt for choice with several national and state parks to explore in the wider region, including North Cascades, which is free to visit and home to more than 300 glaciers, and Mount Ranier National Park, where you can hike through the ancient forests and subalpine wildflower meadows.

You can book a hand baggage-only ticket or make the most of our generous baggage allowance.

If you hold a passport from a country or territory outside of the listed areas, you may need to apply for a visa before you travel.
