SkyJet is replacing the three aircraft that fly in and out of its Houston hub, and it plans to purchase three new aircraft from the Airbus A330/A340 family. SkyJet has already decided to configure the three aircraft with only coach seats and no first-class cabin, but the airline has not yet decided on the size of the aircraft. The A330/A340 family comes in a wide range of sizes, from 240 to 380 coach seats. To decide on an aircraft size, SkyJet must consider both the cost and revenue implications. On the cost side, a larger aircraft is more expensive to purchase and more costly to operate. The purchasing terms and performance data show that the total cost of one flight from, say, Houston to Miami, includes a fixed cost of $12,000 per flight and a variable cost of $40 per seat (whether occupied or not). These numbers are calculated from all costs associated with the flight, including fuel, labor, and maintenance. The cost parameters for the other five flights in each bank in and out of Houston are nearly identical because all six flights are approximately the same length. Assignment 1. Assume that SkyJet purchases three identical aircraft. How many coach seats should SkyJet order for the three new aircraft? 2. Now suppose that the three aircraft can be different sizes, between 240 and 380 coach seats. a. How do you think the three aircraft should be used to service the six flights? Should the same aircraft always fly to and from the same spoke city? Why or why not? (Hint: You do not need Solver to answer part a). b. How many coach seats should SkyJet order for each of the three new aircraft? 3. Airbus is offering SkyJet a one-time, $5 million discount if it will order three identical aircraft because it is cheaper to manufacture three identical planes. Should SkyJet take the discount? In deciding this, you may assume that SkyJet operates 3 banks per weekday (Mon-Fri) through Houston and the revenues and demands for every bank on every weekday are equal to the demands in Tables 1 and 2 of the (A) case.
