i regret to tell you that the A300-600 is dying out very rapidly. not many companies operate the type apart from a few african and middle-eastern carriers. monarch in the uk and fed ex have a few but hardly recruite outside of their staff on the type.
good news is you can operate both the A300 and A310 if i'm not mistaken with just a week in the class room.
i enjoy flying it but its not practical. if you can get a A320 type rating i would deff take it, it opens so many more doors.
