Looking for Heathrow to Seattle flights? This October, you can fly from London Heathrow to Seattle with Alaska Airlines for £445 return, with 23kg baggage included.

The flight is direct, making this a particularly convenient option if you want to travel from the UK.

Fare shown: £445 return. Flight availability and fare conditions can change, so check the current availability when booking.

Why This Heathrow to Seattle Deal Is Worth Considering

For travellers heading to the United States, the biggest advantage of this offer is the direct Heathrow to Seattle route.

A direct flight means you can avoid the extra airport time involved with connecting flights. There is no need to get off the plane, find another gate and wait for a connecting service before continuing to Seattle.

The 23kg baggage allowance also gives you useful space for clothing and other essentials for a two-week trip.

With travel from 12 October to 26 October 2026, the dates also give you around two weeks in Seattle and the surrounding area.

What Makes Seattle a Great October Destination?

Seattle is more than just a gateway to the United States. The city is known for its waterfront setting, coffee culture, music history and views of the surrounding Pacific Northwest landscape.

October can be a good time to experience a different side of the city compared with the busy summer period. If you enjoy city breaks, food, museums, markets or exploring the outdoors, Seattle gives you plenty of ways to fill a two-week trip.

Some of the places visitors commonly look to explore include:

• Pike Place Market – one of Seattle's best-known attractions, with food stalls, shops and local produce.
• Space Needle – an iconic part of the Seattle skyline with views across the city.
• Seattle Waterfront – a good area for walking, restaurants and views across Elliott Bay.
• Museum of Pop Culture – a popular stop for music, film and popular culture fans.
• Chihuly Garden and Glass – known for its colourful glass artwork beside the Space Needle.
• Lake Washington – a different perspective of the city away from the central tourist areas.

You could also use Seattle as a starting point for exploring more of the Pacific Northwest if you are planning a longer US trip.

Is £445 a Good Option for a Return Flight to Seattle?

At £445 return, this Alaska Airlines offer could be worth considering if your dates are flexible enough to travel from 12 to 26 October 2026.

The value becomes particularly relevant when looking at the features included in the advertised fare:

£445 return + direct flights + 23kg baggage

That combination can make the offer more appealing than simply comparing the headline ticket price. A cheaper connecting flight may not necessarily be the better option if it involves a longer journey or does not include the baggage you need.

The exact fare conditions should always be checked before booking, as availability and pricing can change.

Who Could This Seattle Flight Deal Suit?

This offer could work well for several types of travellers.

Couples and city-break travellers

A two-week return trip gives couples plenty of time to explore Seattle without having to rush between attractions.

Families

The direct routing can make the journey simpler, particularly for families who would rather avoid changing planes during a long-distance trip.

Solo travellers

If you are travelling alone, Seattle provides plenty of attractions, neighbourhoods and activities that can be explored at your own pace.

Travellers visiting the Pacific Northwest

Seattle can also be useful if you want to see more than one destination during your US trip. You could plan additional travel around Washington State or the wider Pacific Northwest after arriving.

What Should You Know Before Booking?

A good flight deal is not only about the advertised price. Before confirming your booking, it is worth checking the details that matter to your particular trip.

Check your travel documents

Make sure your passport is valid for your trip and check the current entry requirements for travelling to the United States.

Check the baggage allowance

This offer includes 23kg baggage, but check the booking conditions for exactly what is included in your fare and whether cabin baggage has separate restrictions.

Check the dates

The advertised travel dates are 12 October to 26 October 2026. If you need to travel on different dates, the £445 fare may not apply.

Check the final fare

Flight prices can change depending on availability. The price advertised is therefore best treated as the current deal rather than a guaranteed price for every booking.

If you are planning a trip to Seattle this October, this offer provides a straightforward way to travel from London. For travellers who value a direct Heathrow to Seattle flight and want checked baggage included, this is an option worth checking while the advertised fare is available.
