Allegiant Airlines' last flight out of Casper will be January, 1st 2018.
Allegiant Airlines decided to cut ties with the Natrona County International Airport.
Officials told News 13 Allegiant is making the jump, to bigger airports.
It's unknown how many jobs will be affected by their decision.
Casper/Natrona County Airport Director Glenn Januska commented, “Some of the business that support Allegiant, the bar in the restaurant, and other business like that. They are going to have some impact on all that. Some of it's going to be us; some of it's going to be some of the business that will suffer a little bit also."
The airport will lose about 26 thousand dollars a year when Allegiant pulls out.
