In general, the Frontier Airlines EarlyReturns program offers to match status with other loyalty programs on a tier by tier basis. This means they will consider granting an equivalent status level within the EarlyReturns program to the status you currently possess.
Contact the EarlyReturns program directly about this offer, at:
attest@flyfrontier.com
They will ask for details of your current program membership and status level before making the match.
