Frontier Airlines spokeswoman Lindsey Carpenter declined to give details Friday about why the company stopped service, citing "competitive reasons."
But Provo Mayor John Curtis said in a statement that it had to do with a reduction in Frontier's fleet of smaller aircraft.
The airline began offering daily flights between Denver and Provo Municipal Airport in June 2011. Curtis says the company had been using a 99-seat jet and announced earlier this year that it would switch to a 140-seat Airbus, but has since changed course.
Curtis says the decision to suspend flights was disappointing, but called it a "temporary setback" and says the city will continue to look at other airlines that might service Provo.
