This is not an acceptable way of transportation of this material since cost will be prohibitive. The fact that we used it for the last consignment does not mean it will now become our regular mode of transportation.
Consequently, I will expect that if you gave an order to Premium foods with sufficient lead time for delivery and they fail, then they have to bear the differential cost of airlift the stop- gap quantity.
Therefore the condition for airlifting this order will be that you calculate the cost differential and get the commitment of Premium foods to bear that cost.
