a day to SJC. In 1995 Reno Air Express was operating codeshare BAe Jetstream 31 nonstop service from Eureka/Arcata, Reno and San Jose flown by Mid Pacific Air on behalf of Reno Air. In the mid-1980s United Airlines entered into a code sharing agreement with WestAir, a commuter airline that had previously served STS with Cessna 402s and de Havilland Canada DHC-6 Twin Otters to San Francisco. WestAir then began flying as United Express to SFO until 2001. Westair operated Embraer EMB-110 Bandeirante, Short 360, BAe Jetstream 31 and Embraer EMB-120 Brasilia turboprops. In 1989 jet service arrived in Santa Rosa when WestAir operating as United Express began flying four weekday BAe 146-200 nonstops to Los Angeles, soon replaced with Embraer EMB-120 Brasilia turboprops with this service to LAX then ending in 1991. The Westair BAe 146s were Santa Rosa's only jet flights until Allegiant Air jets appeared on May 19, 2016 followed by American Eagle on February 16, 2017. WestAir formerly operated as Stol Air Commuter flying Britten-Norman Islanders and Trislanders to San Francisco. Stol Air Commuter had administrative offices in Santa Rosa. United Express left Santa Rosa in 2001 (and would not return until 2017) with the airport not having any scheduled passenger airline service for several years during the early and mid-2000s. In March 2007 airline service resumed; Horizon Air, a subsidiary of Alaska Airlines, began flights to Seattle/Tacoma and Los Angeles operated with Bombardier Q400 propjets. Horizon then added flights to Portland, Oregon in late 2007, to Las Vegas in early 2008, and to San Diego in mid 2012. In early 2011 Alaska Airlines announced it would retire its Horizon brand, and all flights operated by Horizon now use the Alaska Airlines name. In June 2012 the airline ended flights from STS to Las Vegas. As part of an agreement between the airport, Alaska Airlines, and the local enotourism industry, it was announced in January 2012 that passengers were allowed to check a 12-bottle case of wine for free on all Alaska Airlines flights from the airport. All Alaska Airlines flights from Santa Rosa are currently operated with 76-seat Embraer E175 regional jets. E-175s currently fly nonstop to Burbank, Los Angeles, Orange County, Portland, San Diego, and Seattle.
