Alaska Airlines plans to expand service to a dozen global destinations over the next several years, starting with this European capital.

Alaska Airlines on Tuesday announced it was adding nonstop flights between Seattle and Rome next year, its first transatlantic route. The Italian capital was not previously served by an airport in the U.S. Pacific Northwest. It’s the third long-haul destination Alaska has added at its Seattle-Tacoma International Airport hub after Tokyo and Seoul.

Alaska Airlines is planning to start its first flights to Europe from Seattle, which will add Rome as a destination.
