This Is What Happens To Uneaten Plane Food - Tasting Table
Briefly

Uneaten airline food is mostly discarded to avoid contamination risks, resulting in significant waste. Despite airlines' efforts to manage excess food—like rounding meal orders using AI—leftover food often ends in incinerators or landfills. Some airlines, such as Cathay Pacific, have begun sending surplus food to be repurposed, while others look to donate unused meals as regulations ease. Pre-ordering meals by passengers is also seen as a viable method for minimizing this waste, though additional fees may discourage participation.
The prevalence of food waste from airlines is staggering, with most uneaten in-flight meals simply discarded due to health regulations, despite such waste being largely untouched.
AI technology is emerging as a significant tool for airlines, assisting them in forecasting meal requirements and consequently reducing the food waste associated with flights.
