London to Seattle

When you take an Icelandair flight to Seattle from London, you can either travel from London Heathrow or London Gatwick. Both offer excellent transport links from the city centre, frequent departures and a wide range of airport services for travellers.

As a major international hub, flying from Heathrow might give you more flight options and flexibility about when you travel. As the smaller airport of the two, Gatwick is a bit less crowded but there are often fewer flights going to the US, so you’ll have less choice when booking your travel.
