SAN FRANCISCO — Alaska Airlines has been selected as the official airline of the San Francisco Giants baseball club, the airline announced Wednesday.

The Giants initiated a partnership in 2008 with Virgin America, an airline that Alaska bought in 2016 in a $2.6 billion deal. The new agreement effectively extends that prior arrangement.

“Our commitment to San Francisco and our Bay Area employees has never been stronger,” said Andrew Harrison, chief commercial officer at Alaska Airlines. “We’re thrilled to extend the Giants sponsorship for the next seven years.”

As part of the deal, Alaska Airlines unveiled a design for a new Giants-themed Airbus 321 featuring the Giants logo and team colors, along with a Golden Gate Bridge image, that will begin flying early next year.

Alaska also will launch a seasonal, twice daily flight from San Francisco to Phoenix for Giants fans to attend spring training in 2018.

“We look forward to working with the great people at Alaska to continue enhancing our customers’ experiences both at the park and on the plane through our new and expanded partnership,” said Jason Pearl, Giants senior vice president of partnerships and business development.
