Flight times for our Seattle-London route will allow guests to spend a whole day in either city before boarding their flights – a potential benefit for business travelers. London is the largest corporate market from Seattle.
Alaska will operate out of London Heathrow’s Terminal 3, which facilitates convenient connections to additional destinations across Europe and beyond on oneworld member airlines and our additional global partners.
