When asked about this new service, Airport Director Cris Jensen stated,"We are excited to enter the California market with this flight. With eight of our top twenty-five destination markets in California, we believe this route will be the first step toward daily service to the Golden State."
In fact, this new service follows a trend United has adopted in introducing new service at airports across the country. In this model, weekend service is first introduced and, if sucessful after a trial period, may then be increased to daily service. Chicago (ORD) service by United at Missoula followed this exact pattern, in fact, and what was weekend service to Chicago last summer is now daily service from Missoula this summer.
