Green Airways flies several daily flights from Dallas to Chicago with 150-seat planes. Based on historical data, the flight on Wednesday evening before Thanksgiving is always sold-out. However, there are usually no-shows, so the airline decides to improve revenue by overbooking. The distribution of no-shows is according to the table below and the airline estimates that the cost of bumping a passenger is about 10 times more than the ticket price. How many seats should Green Airways overbook? Please show work. Thank you.

Let the ticket price = P
So, the cost of bumping = 10*P
Cost of overbooking one less seat than the number of no-shows,
Cu = P
Cost of overbooking one more seat than the number of no-shows,
Co = 10P
So, the optimal in-stock probability = Cu / (Co + Cu) = P / (10P + P) = 0.09

The cumulative probability crosses the optimal in-stock probability for the number of no-shows=1
So, the optimal overlooking = 1

Case 7.2 Skyhigh Airlines Skyhigh Airlines flight 708 from New York to Los Angeles is a popular flight that is usually sold out.
