Routt County's jet flights from Yampa Valley Regional Airport to Denver and Salt Lake City, Utah, were 42 percent full in June.
Both flights are operated by SkyWest Airlines, though the Salt Lake route is on Delta Connection, and the flight to Denver is on United Express.
The combined service on SkyWest saw 4,041 passengers board the planes in Hayden during June and 4,334 disembark, according to figures maintained by Routt County. Schedules published by the Steamboat Springs Chamber Resort Association show the Salt Lake service began June 6. It will continue until Sept. 1.
The pricing on the flights suggests the demand is higher for travel to Denver and cities beyond that United hub city.
Delta Connection is offering round-trip flights in August spanning 670 miles from Hayden to Salt Lake City and back for $178 round trip. Round-trip flights to Denver are half the distance and priced at $417.
Load factors on the flights to and from Yampa Valley Regional Airport in June didn't measure up to what SkyWest was experiencing system-wide with its subsidiary, Atlantic Southeast Airlines.
The airline reported that although the number of June passengers slipped by 1.4 percent to 3,061,417, its aircraft operated at 80 percent capacity. That correlates with a reduction of 50,000 available seat miles. Year to date, SkyWest's load factors are 77 percent.
System-wide, SkyWest operates about 2,696 daily departures. Travelers in Northwest Colorado can access two new regional destinations via Delta Express. SkyWest announced July 7 it was beginning twice-daily round trips between Salt Lake City and two Wyoming cities, Rock Springs and Gillette on 30-passenger Embraer 120 turboprops.
