Rumor has Envoy transferring more E145s to Piedmont starting Sept 2021. Also, it appears Envoy has a significant order (62?) of new E175s, likely to backfill for those E145s, plus potentially some growth. But those are unconfirmed rumors.

Will Piedmont fly those additions birds or will they retire some of their oldest E145s? Don’t know. Will those additional E175s mean reduced flying for the non WO regionals flying for AA? Don’t know.
