According to
FlightRadar24, this Republic aircraft is normally American Eagle, but has been recently used for both UA and AA flights.
N805MD has actually been operating exclusively on the UAX contract since at least early December. AA flight numbers appear to come up in FR24, but they match their simultaneous UA-coded numbers, and all are flown on UA routes.
