Spirit Airlines is kicking off its new service and Denver International Airport and Phoenix-Mesa Gateway Airport.
The Florida-based low cost carrier will have one daily non-stop each way beginning Thursday. The flights leave Denver at midmorning each day and leave the east Phoenix suburb of Mesa for the return late in the morning.
Spirit touts low fares but makes up some of the difference with fees that account for 40 percent of its revenue. The average customer pays more than $100 per round trip in fees.
