When a freight forwarder FF contracts airline A to move freight, the freight becomes A's freight.
If A is now not able to move the freight and subcontracts another airline B, it still remains A's freight that is now also B's freight.
If FF contracts airline C instead of airline A, it is no longer A's freight but it is now C's freight.
That is the difference, even if the freight comes from the same forwarder FF and moves out of the same warehouse.
My support still goes with the Amerijet Crews.
