SIOUX CITY, Iowa (AP) — Frontier Airlines is saying goodbye to a Sioux City airport, ending a four-month stint serving the community. The Sioux City Journal reports the flights began with much fanfare and were popular, but the airline says it’s focused on faster-growing markets, such as Cincinnati/Northern Kentucky International Airport. In August, the airline announced that it was stopping its nonstop flights from Sioux Gateway Airport to Denver International Airport.

The last flight from the Sioux City airport was on Friday. Frontier flights traveled three times each week between the two cities. American Airlines is now the only other carrier at Sioux Gateway Airport. The airport’s director says Frontier’s lease in the terminal ends next month. He says crews from the airline will soon remove computer systems and ground equipment.
