In a method of loading checked luggage on unit load devices corresponding to an aircraft having a passenger compartment, each piece of checked luggage is associated with a unique identifier. Each piece of checked luggage is weighed and its weight is associated with its corresponding unique identifier. A best possible luggage placement is calculated considering a distribution of passenger weight, thereby allowing the passengers to sit at their preferred location rather than by pre-allocation. A desired placement of the checked luggage is calculated based on the weight of each piece of checked luggage, the acceptable distribution of weight in the passenger compartment and overall fuel state over mission profile. Loading personnel are allowed to place luggage in the unit load devices and are instructed to stop loading the selected ones of the unit load devices when a deciding point is dynamically achieved by a recalculation of center of gravity shift each time a bag is loaded onto one of the unit load devices so as to achieve the best possible placement of check luggage. The recalculation of the center of gravity shift is done based on placement of the unit load devices in the aircraft luggage compartments.
