Check out this awesome code share between Seattle and London on Virgin Atlantic and Delta! The best fares are between October 2019 and March of 2020 (excluding Christmas and New Years). This is Basic Economy / Economy Light fare so a normal sized carry on and personal item are included. Checked bags are $60 each way so upgrade to main cabin if you plan to do that and you’ll get advanced seat assignment.
