The carrier will celebrate the convenient new service to Arizona with introductory fares as low as $99* each way.

"We are extremely pleased to again expand the Allegiant brand of low-fare, nonstop jet service to the Sioux Falls community," Maurice J. Gallagher, Jr., president, CEO of Allegiant Air said. "This is an exciting new addition for our airline and our customers as we launch the only scheduled service between Sioux Falls and Arizona."
