Delta will initially operate two daytime round trips between Sonoma County and Salt Lake City, one of the airline’s major western hubs with connections to destinations across North America and abroad. Delta’s arrival in Sonoma County will support tourism, business travel and economic activity throughout the North Bay. 

“Charles M.
