You are well aware of the constantly changing environment in which airlines operate. Dealing with price fluctuations and other factors related to goods and materials can be incredibly challenging for airlines. This often results in the airline's limited control over the pricing, weight, and other aspects of their products and materials uplifted to their aircraft. To address this, we have introduced Sub Material and Food Item Versioning, allowing airlines to effectively capture all changes in Sub Materials and Food Items. With this feature, airlines can maintain an accurate record of all states of Sub Materials and Food Items, facilitating precise calculations for meal and load orders. As a result, airlines will experience enhanced accuracy and clarity in what is uplifted on their aircraft.
