One customer per aircraft

The old question about cardinality again:
Assume equipment means aircraft and that we walk through the BDM from equipment to customer:
One aircraft belongs to one and only one flight.
This one flight belongs to one and only one segment.
This one segment belongs to one and only one itinerary.
This one itinerary belongs to one and only one customer.
Therefore one aircraft can have only one customer and it is reasonable to beleive that there is something fishy with the cardinalities in the BDM.
What do you think about the logic in the statements above?

Hi Joachim,

Your logic is a bit peculiar
What do you mean by saying:

One aircraft belongs to one and only one flight.
