Applying cost-cutting analysis as an intellectual exercise...

Airline ticket sales are so price driven that for much of the market, losing some percentage of bags won't change purchase decisions.

I wonder if it's possible to identify which bags are from budget customers and for Kansai Airport to cut corners for those, accepting a certain loss percentage and saving money. It may not be:

> In addition to monitoring bags with sensors, employees also patrol the area to check for dropped bags. According to the airport management company, this additional step significantly reduces the risk of lost baggage.

I think you either patrol for all dropped bags or give up the patrols entirely, assuming that bags from first-class and budget passengers end up in the same area.
