This from Frontier Airlines. A new pathway for college students from college to Frontier. Not much detail but it appears to leave out the intermediate step of regional flying between CFI and the airline...or maybe I've overlooked something:
The careers page at Frontier specifies this:
"500 hours jet/turbo-prop"

"Prior to employment with Frontier Airlines, program participants will also need to be employed by Embry-Riddle as a flight instructor and must obtain the R-ATP required experience."
