Key facts about Seattle

How to get cheap flights from London to Seattle Tips and advice from our flight experts

There are around 2,131 weekly flights from London to Seattle – so if you’re planning a visit to this US city, it’s worth spending some time searching for a cheap flight. The good news is, there are loads of low-cost options on this route. Flights from London to Seattle land at Seattle-Tacoma International Airport (SEA), which is also known as Sea-Tac, but you’ve got three London airports to take your pick from back in the UK.

If you go from London Gatwick (LGW), you can fly direct to Seattle with Norwegian Air, who regularly offer some of the cheapest flights on this route. There are indirect flights from this airport, too, which could save you some extra cash.

Fly from London Heathrow (LHR), meanwhile, and you’ve got even more choice. Direct flights are available with British Airways, Virgin Atlantic, Finnair and more, which makes this the most popular departure airport in the city. Or, if you go from London City Airport (LCY), you can fly with carriers including SWISS – just bear in mind all flights from this airport will include at least one stopover.

Of course, when you fly is just as important as where you fly from, so always compare flight prices either side of your preferred travel dates. If you’re pretty flexible, you could fly in May when prices are generally cheaper – it’s off-season season, so accommodation is likely to be cheaper, too. July, meanwhile, is the height of the summer tourist season here, making it one of the most expensive times to fly to Seattle.
