FRONTIER AIRLINES COMPANY FREQUENCIES

Thought I would try this again. Does anyone know what the company frequency for Frontier Airlines in OKC is? Its the air to ground frequency that the flights call in-range on. Frontier has 3 flights a day from Denver which are actually Republic flights with the call sign of BRICKYARD. If anyone knows this frequency please let me know. I would greatly appreciate it. Im a former Frontier employee and like to listen to the in-range calls to various airports that Frontier flies into around my area.

Thanks,
Mike
