Case 7.2 Skyhigh Airlines Skyhigh Airlines flight 708 from New York to Los Angeles is a popular ight that is usually sold out. Unfortunately, some ticketed passengers change their plans at the last minute and cancel or re-book on another ight. Subsequently, the airline loses the $450 for every empty seat that the plane flies. To limit their losses from no-shows, the airline routinely overbooks flight 708, and hopes that the number of no-shows will equal the number of seats oversold. However, things seldom work out that well. Sometimes ight 708 has empty seats, and other times there are more passengers than the airplane has seats. When the latter happens, the airline must \"bump\" pre-ticketed passengers; they estimate that this will cost them $275 in later accommodations to bumped passengers. Fortunately for the airline, hopeful passengers usually show up at flight time without tickets and want to get on the flight. The airline classifies these passengers as standbys while it waits to determine how many seats, if any will be available. Standby passengers can help offset the loss associated with flying an empty seat, but the airline suffers no penalty when a standby passenger is not able to receive a seat. Airline records indicate that the number of No-shows and Standbys will vary according to the probability tables below: Number of Relative Number of Relative MirSims 0 0.04 0 0.26 1 0.08 1 0.34 2 0.14 2 0.24 3 0.25 3 0.11 4 0.30 4 0.05 5 O. 13
