Always fly Delta domestically in the US ahead of Alaskan Airways.

I booked this through Air France but was carried by Virgin (who were excellent), BUT the free baggage for AF is not carried over by Virgin so there was an unexpected additional cost. Learning point - book with the carrier not the airline,

Staff helpfulness and friendly attitude, along with the nice treats (hot towels, popcicles, lots of beverage service, two meals) made my flight experience very pleasant! Thank you!

I was very happy with the first part of my flight, London to IAD. I was comfortable, the flight staff were perfect, the food was tasty, it was good trip. I upgraded to first class for IAD to SEA, but was very unhappy for that leg. It was the most uncomfortable seat I was ever in in hundreds of trips and I was literally miserable throughout the flight because of it and got a bad backache within minutes of being in the seat. I will check to see which plane I was on and try to avoid that model in future.

Staff were very friendly. There was a new crew member who was lovely. He kindly gave us iPads to use as our movie screen was not working.

Buying extra luggage didn't work correctly while checking in so had to purchase at the airport

Book a Flight to Seattle

One of the largest cities in the United States, Seattle is relaxed, freethinking, and packed with beautiful architecture and cultural curiosities. One of the few big cities in the world where skyscrapers and forested mountains stand tall in the same skyline, America’s famous Emerald City is where you can live the truly cosmopolitan high life.


When to Book Cheap Flights to Seattle

Being located on the Pacific west coast of the USA, finding very cheap flights to Seattle from the UK can be difficult. However, because the weather tends to be nicest in July and August, these are when flight prices are at their highest. In late spring and early autumn, the weather remains fine but, with fewer tourists, these are good times to try and find a good deal. Usually with foreign travel, it’s important to avoid major festivals, but Seattle is so jam-packed with them – including everything from jazz festivals to world music and film – this is unlikely to have too much impact on costs.


How to Find the Best Deals to Seattle

Due to its distance from the UK, the best way to find cheap flights to Seattle from London is to book as far in advance as you can. Failing this, being flexible on travel dates will also help: use our ‘Show flexible dates’ option, found above your initial search results, to help you here.

The cheapest and most direct flights tend to depart from London. However, flights with additional connections – although less convenient – can sometimes be more affordable.

Whatever search you run, use the dropdown menu to sort results by price from lowest to highest.


UK Departures to Seattle

The only direct flights departing for Seattle from the UK fly from London. While you can travel to Seattle from elsewhere in the UK, this requires a connecting flight. From London, flight time is approximately 10 hours. From elsewhere in the UK this varies depending on connection and air carrier.


Main Airports in Seattle

Seattle-Tacoma International Airport lies 13 miles south of downtown Seattle. One of the busiest airports in the world, it receives over 45 million passengers annually. Make sure you book a window seat if you can – the view from the plane as you come in to land over the mountainous terrain and broken coastline is really something.

Which Airlines Fly to Seattle?

Air carriers operating to Seattle from the UK include:


How to Get Around in Seattle

After your flight lands, getting into Seattle from the airport is easy. The city has more forms of transport available than most. Buses, trams, trolleys, monorail, taxis, ferries and ride sharing are just a few of the ways of getting around.

For just eight dollars, you can get yourself an all-day regional transit pass, giving you access to all of the city’s transport (excluding cabs, monorail and Washington state ferries).

To make the most of the dramatic landscape that Washington has to offer, you could also hire a car in Seattle.


Must-Sees in Seattle

Visible from almost everywhere in the city is Seattle’s icon Space Needle. The panoramic views from the top of this huge tower can’t be beaten. Take a ride on the revolving restaurant to really enjoy the view in style.

Be sure to head to Pike Place Market too. Located on the city’s waterfront, you’ll get a feel for the way locals do business. It’s also where you’ll find the houseboat made famous by the eponymous movie, Sleepless in Seattle.

Finally, for a taste of Washington’s countryside, head for a hike along the verdant base of colossal Mount Rainier. It’s truly awe-inspiring.


Tips for Travelling in Seattle

When travelling to the United States, you will need to apply online for a visa or an Electronic System for Travel Authorisation (ESTA). Be sure to do this well in advance of your trip.

Once you’ve arrived, the city has plenty to keep you entertained. However, with whales living off Seattle’s rugged coastline, you shouldn’t miss an opportunity to go on a whale watching tour. Even if you don’t get to see one of these majestic creatures up close, you’ll enjoy some exquisite panoramas of Seattle’s unique skyline.
