Allegiant Air is spreading its wings.
The Las Vegas-based budget airline says it is undergoing its biggest expansion ever.
Allegiant is announcing 44 new non-stop routes, including flights to Boston, Chicago, and Houston. But also in Sioux Falls, with a new non-stop service to Nashville.
It's also offering one-way fares on the new routes for just $33.
Officials say they added 15 airbus jets in 2019 and plan to expand that number this year.
Service between Sioux Falls and Nashville begins May 21 and currently runs through August 16.
