Q. Airline passengers today stand in numerous lines, are crowded into small seats on mostly full airplanes and often spend time on taxiways because of air-traffic problems or lack of open gates. But illustrate what gripes travellers almost as much as these annoyances is finding out that the person sitting next to them paid a much lower fare than they did for their seat. This concept of "yield management," also known as "income management," results in ticket pricing that can range from free to thousands of dollars on the same plane. Consumers also experience this practice when booking hotel rooms, even up to the time of check-in. Make the case first for and then against, this type of pricing system. To which of the 2 arguments do you subscribe and why?
