• United Airlines launched its newest route from Denver (DEN) on 8 March, with the carrier initiating a daily service to Santa Rosa (STS) in California. The Star Alliance member will serve the 1,566-kilometre airport pair daily using its fleet of CRJ 200s. No other airline presently operates between the two US airports. This becomes United’s second route to Santa Rosa, with it already serving the airport from San Francisco. In 2018, a reported 440,644 passengers travelled through Santa Rosa Airport, with this representing an 11% increase versus 2017 when 397,787 people used the facility. In total, the airport has non-stop service to 10 destinations by four airlines, with the other three serving operators being Alaska Airlines, American Airlines and Sun Country Airlines. An 11th destination will be added in June, with American starting flights from Dallas/Fort Worth.
