(Seattle, WA) -- A pilot shortage is forcing Horizon Air to cancel more flights. The Alaska Air regional carrier reports that it's cutting its schedule through at least January, with 700 flights jettisoned during this month alone. The "Seattle Times" reports that newly hired pilots are still being trained on the airline's new Q400 turboprops. When they graduate by the end of the year, the company expects to return to its regular schedule. Horizon serves 45 cities in the west.
