Doesn't specifically state SkyWest is flying it, but it will be a CRJ-700 operator so chances are highly likely.

Delta also is starting non-stop service between Spokane and Los Angeles with one flight daily beginning June 10.

Seattle to L.A. flights will depart at 6.40 a.m., 11.54 a.m. and 6.55 p.m daily. Flights from L.A. to Seattle leave at 8:31 a.m., 3:20 p.m. and 9:20 p.m.

From Spokane, the flight will leave for L.A. at 6:45 a.m. daily. The L.A.-Spokane flight leaves at 7.50 p.m.

Both the Seattle and Spokane flights will be year-round and operated by SkyWest Airlines (as a Delta Connection).
