Alan,
Didn't know CPA (Cargo) uses it's flightnumbers on different routes. In that case it's up to you to decide which route will be in the d/b. As far as I know, CPA did stop freighters ops to/from MAN, but correct me if I'm wrong.
Something else: I've just logged 4848D8 which appears in the d/b as Catalina PH-BBY, but the correct registration should be PH-PBY.
Michel.
