What happens to the unused food after a flight? Does it get all destroyed (on-site or off-site) or is there some alternative use (e.g. Charity ) that it gets put to. Does the incoming food truck cart it off with the carts or is it handled by the Janitorial / Clean Up crews.
On shorter sectors can some items be used on the next flight with the carts only being "topped up"?
PS. Obviously, I'm referring to the perishable items with short shelf lives. Not talking about peanuts and other packaged items that last with longer shelf lives.
