Frontier Airlines Seasonal Shut Down

Sioux Gateway Airport announced today that Frontier Airlines will begin a seasonal shut down of the flights to Denver from Sioux City effective October 24, 2014. The change in schedule will appear in the Frontier Airlines reservation system on Sunday, August 24th. Frontier plans to resume the service sometime after the beginning of 2015. The Frontier service to Denver has been very well received by Sioux City and the surrounding area, with passenger enplanements in July exceeding 90% of the available seats. Frontier is reallocating aircraft for their 4th quarter schedule so several markets will be affected by the schedule changes. Please contact Frontier Airlines directly at their toll free reservation number to make any changes to existing reservations 800-432-1359. Customers can also visit
