American Airlines and United Airlines said the carriers would add international routes in 2020.

American said it would debut the first and only year-round service from Portland, Oregon, to London along with Atlantic Joint Business partner British Airways, starting June 1. British Airways will operate the flights, connecting Portland International Airport and Heathrow Airport. American is also adding eight new trans-Atlantic routes for summer 2020 alongside joint business partners Iberia and Finnair.

“Our partnerships mean more new routes and more options for our customers around the world,” said Vasu Raja, senior vice president, American Airlines. “With this new British Airways flight between London and Portland, American and our partners will offer more than 1,000 flights every week between North America and Europe.”

United is adding a new route, a daily non-stop service from its hub at San Francisco International Airport to Dublin (DUB), Ireland, June 5, 2020.

When it starts, the route will make United the only airline to offer daily service direct to Dublin from the West Coast. The route will be operated with United’s fleet of Boeing 787-8 Dreamliner planes.

“Dublin and the Silicon Valley are two regions synonymous with big tech,” said Patrick Quayle, vice president, United Airlines. “Many global tech companies have a major footprint in both regions, and they need a carrier with an extensive worldwide network to help conveniently connect their business. As the only U.S. airline to serve Ireland from the West Coast, United is uniquely suited to provide the connectivity these companies and economies need to continue thriving.”
