Cheap flights 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:

  • Delta
  • Air Canada
  • KLM
  • Virgin Atlantic
  • United
  • American Airlines
  • British Airways

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.

I'm not sure what you mean for "dba" trip, not very customer friendly. However I guessed it refers to my flight and it was good.

Good flight

I booked this one late due to unforeseen circumstances. As such, I could not request dietary requirements for the meal. The person at the check in desk arranged a 20 euro voucher so that I could buy my meal at a restaurant before boarding. Then when I returned, as the queue had moved on, she led me to the priority boarding area. Smashing service!!

Happy service

Really impressed with everything from the booking process, the customer service live chat, checking in and the facilities on the plane. Loved being able to order snacks from the tv screen and pay for them by swiping my card on the screen! Staff were just wonderful. Even though the flight was delayed, these things happen, everything else ran so smoothly and the staff are just wonderful. Best flight experience of my life (50kg of luggage total, 2 meals and a beer all included in the price was a huge bonus too!)
