Saw this article today which alludes to another air carrier with a limited number of planes contemplating coming to Walla Walla, WA. ALW is currently served only by Horizon on 3 flights per day, and I wasn't aware of any other viable carriers. Big Sky operates a number of short runs in the WA-ID-MT area, but I was under the impression they were essentially operating under contract by Horizon. Could this be Skywest? Some new airline? I know that Skywest already has a number of daily flights out of nearby PSC operated as United Express and Delta Connection, so I would be kind of surprised if it was them...
