TWIN FALLS, Id. ( KMVT - KSVT ) Skywest Airlines will temporarily suspend the daily evening departure at Magic Valley Regional Airport from Dec. 1st through Dec. 19th. However, the evening flight departure remains on sale for the period before and after the suspension dates. The reduction is part of a Skywest route-system seasonal adjustment to match air service demand, which typically declines in between peak holiday travel after thanksgiving and prior to the December holidays.
