Yes MAG bean counters have probably done their sums and come up with “its not worth it” answer.
Income from a freight movement I would say is less than that of a PAX aircraft, you have the movement fee and a percentage of concessionaires income such as fuel. There would be no income from PAX handling, car parking, shop and food sales etc.
Chaps is much more qualified on the subject and Im sure he could clarify my points.
I am a huge supporter of MAN and would love to see the lines of 747 freighters once again but while the group has 2 of the largest freight hub airports on its accounts sheet why bother ?
