I observed that one truck can serve ~2 Med. Stands simultaneously within the turnaround time in my airport. I did a back of the envelope calculation and came up with profits of ~2400 $ / day (~4 flights/day * 2 Stands * ~100 Meals / flight at $3) against costs of ~$4200 /day (1 Truck at $100/h and 1 depot at the lowest setting at $75/h). Slightly better for waste (assuming the $1000 operating is per day).
Do I miss something, e.g., is this only profitable for big stands/planes or should I fleece the airlines for more money? Thanks in advance
