Bonus treat in the release:
"
As Seattle’s global carrier, Delta plans to launch nonstop service to London-Heathrow in 2021. The route expands the airline’s lead of offering the most global destinations from Seattle than any other airline, with London joining Delta’s existing nine international markets. The service also complements partner Virgin Atlantic’s twice-daily service and offers customers the choice of three daily flights."
The war for Seattle escalates to new heights, and nonstop fares from Seattle to London will fall even more.
Side note: It's sometimes surprising to see how large of a hub SEA has become for DL - the PR says that they'll operate 190 flights a day this summer.
