This isn't exactly new news, it was announced on August 14.
But I thought I should bring it up since we don't hear much about Big Sky Airlines.
On September 16, Big Sky Airlines will start 2 daily non-stop flights from Denver to Idaho Falls. This will be an entirely new route from Denver, and Denver's 2nd destination in Idaho.
Passengers will be able to make connections on America West to Phoenix or on Northwest to Minneapolis/St. Paul with the code-share agreement that Big Sky has with these 2 airlines.
