SANTA ROSA -- Passenger volume continued to climb at the Charles M. Schulz--Sonoma County Airport in November, increasing 1.5 percent versus the same month in 2011 and 3.5 percent for the year, according to recent passenger data.

It was the busiest November for commercial flights in Santa Rosa and the latest record-breaking month since Horizon Air began operating at the airport in 2007, according to the monthly report by the airline's parent company, Alaska Airlines.

A total of 17,575 passengers used the airport in November, compared with 17,312 a year before.

Since the start of the year, the carrier has served 190,647 passengers, well beyond the year-to-date high of 172,406 in 2011.

Seattle-based Alaska Airlines operates five flights a day from Santa Rosa to Portland, Seattle, Los Angeles and San Diego. In June, Alaska Airlines, currently the only commercial carrier at the airport, started flights between San Diego and Santa Rosa, replacing service from Sonoma County to Las Vegas.
