British Airways Citi-Express also operate Dash 8-300 and ATP aircraft out of MAN on domestic routes. I'm fairly sure that they are MAN based, unless anyone can correct me? ERJ145's and 146's/Avro's operate the European routes ex MAN, the Avro's being ex-Cityflyer. Half are at Birmingham as well.
All the Jetstreams are long gone, although there is a J41/J31 service to Billund, operated by a Scandinavian based/registered aircraft under BA franchise with Sun Air.
