SANTA ROSA -- Airline passenger volume at Charles M. Schulz--Sonoma County Airport in April increased nearly 3 percent from a year before and slightly from the previous month, according to figures released this morning.

In April of this year, 16,485 people went to and from the airport, according to Alaska Airlines, which operates its Sonoma County flights through subsidiary Horizon Air, the airport's only commercial carrier. In March, 16,158 passengers used the airport, while in April of last year the airport accommodated 16,019 passengers.

In the first four months of this year, 62,319 passengers traveled through the airport, compared with 60,969 during the same period last year, an increase of 2.2 percent. 

Alaska Airlines operates five flights a day from Santa Rosa to Los Angeles, Las Vegas, Portland and Seattle.  The airline earlier this year announced a shakeup to its schedule for Santa Rosa, saying it will discontinue the Las Vegas route on June 3 while adding a new route to San Diego on June 4.  A third flight to Los Angeles will be added at that time.

The airport also is awaiting federal approval for an $84 million upgrade and expansion that would increase its capacity and allow use of larger jets. The Sonoma County Board of Supervisors unanimously approved the project earlier this year.
