It's been more than a decade since the last passenger airline jet plane touched down at Redding Municipal Airport, and that was only for a brief time. Before that it had been many years. That is, until Thursday. Skywest and United, in a joint venture, have upgraded their planes from 30 passenger turboprop Puddle-Jumpers" to 50 passenger twin-engine CRJ-200 jets. There are daily departures at 5:30AM and 3:20PM.
