What happened
Delta Air Lines has filed plans to launch nonstop service between Salt Lake City International Airport (SLC) and Charles M. Schulz Sonoma County Airport (STS) in Santa Rosa, California. The new route launches on October 6, 2026. The service will be operated by Delta Connection using an Embraer 175 regional jet configured with 12 first-class recliners and 20 Comfort+ extra-legroom seats. This marks a new airport for Delta, providing SkyMiles members with a direct link to the Sonoma and Napa wine regions. The launch adds to recent air service growth at STS, which has seen increased activity from Southwest and Alaska Airlines
