abstract

Numerous factors affect air cargo revenue management. Air cargo companies base their cargo charges on whichever is the greater of gross weight or volumetric weight. We developed a cargo consolidation model based on air cargo characteristics, and investigated the effect of cargo density, the Density Ratio of Heavy cargo to Light cargo (DRHL), and the percentage of small cargo on the chargeable weights and revenues of airlines. The empirical results show that a higher DRHL indicates greater chargeable weight, and that as the DRHL climbs to a certain level, the extent of chargeable cargo weights tends to stabilize gradually. The closer the cargo density approaches the most suitable loading density for a flight, the greater the chargeable weight is. A higher proportion of small cargo loaded on an aircraft means higher airline revenue. Our results can effectively combine types of air cargo to increase loading rates and revenues for airlines.

5. Conclusion

This study has validated the factors affecting air cargo revenues, including the DRHL, cargo density, and the percentage of small cargo. Further, we empirically verified our calculations based on the actual operations of a B747e400F all-cargo aircraft operated by a Taiwan airline company. We summarize our conclusion as follows: 1. Under the condition of fully using loadable space and flight payloads, chargeable weights increase with DRHL, and the extent to which these weights increase tends to stabilize gradually when the DRHL rises to a certain level. This indicates that airline companies can accept more cargo combinations of denser heavy cargo and less dense light cargo for the same flight to increase chargeable weights and revenues.
