For ULD allocation we can assume it is expressed in segments (groupings of legs) operated with a single aircraft per segment.<br/>Loading and/or unloading instructions are dispatched to stations at start and end of segment as per need to move<br/><br/><br/>Story for bag segment is bit more tricky. How much of below goes into Baggage Logistics??<br/><ul>
<li>bag must be delivered one or more transport service segments(TSS) down the line</li><li>A TSS may break up in smaller chunks when an aircraft crosses border (present bag to customs at first entry)</li><li>A TSS may break up in smaller chunk when flight has planned aircraft change-en-route (change of gauge)</li><li>Two TSS may join when both are on same aircraft in immediate sequence (Evelien, Olympics)</li><li>Aircraft that services an TSS may change flight midway (triangle flights)</li></ul><p/>
