Alaska Airlines will add a number of new routes from the Pacific northwest US and from San Diego starting in November and December, the Seattle-based carrier announces in a media release.
Beginning 1 November, the airline will inaugurate daily service between San Diego, where it has a growing presence, and Boise in Idaho.
On the same day, the airline launches daily flights from Seattle to Colorado Springs in Colorado, a new Alaska destination, and from Portland in Oregon to Tucson in Arizona.
The Portland-Tucson service reestablishes a route last served by Alaska in 2003, the airline says.
On November 7, Alaska inaugurates service between Seattle and another new Alaska destination, Omaha in Nebraska.
Those routes will be operated by partner Skywest Airlines using 70-seat Bombardier CRJ-700 aircraft.
Daily service between Portland and Reno in Nevada begins on 8 November and will be operated by Alaska subsidiary Horizon Air using 76-seat Bombardier Q400 turboprops.
Alaska last served the Portland-Reno route in 2009, the carrier says.
On December 19, Horizon Air will begin daily seasonal flights using Q400s from San Diego to Mammoth Yosemite airport near the Mammoth Mountain Ski Area in California.
With the new San Diego flights, Alaska will operate 25 peak daily departures from the airport and serve 12 domestic and two international destinations, the airline says.
Alaska will be the only carrier serving the new routes with the exception of the Portland-Reno route, which is also served by Southwest Airlines, according to FlightMaps Analytics.
