PROBLEM 9-3 VDeciding Whether to Discontinue a Flight [LO1 - CC3] Profits have been decreasing for several years at Pegasus Airlines. In an effort to improve the company's performance, consideration is being given to dropping several flights that appear to be unprofitable. CHECK FIGURE A typical income statement for one such flight (Flight 482) follows: (1) Decrease in $6,400 Ticket revenue (175 seats X 40% occupancy x $400 ticket price) $ 28,000 100.0% Less: Variable expenses ($15 per person) 2 2,100 7.5 Contribution margin 25,900 92.5% Less: Flight expenses: Salaries, flight crew 3,6005 Flight promotion 1,500F Depreciation of aircraft 3,100 D Fuel for aircraft 13,600 F Liability insurance 8, 400 Salaries, flight attendants 1,000 S Baggage loading and flight preparation 3,400 Overnight costs for flight crew and attendants at destination 6000 Total flight expenses 35,200 Net operating loss $ (9,300) The following additional information is available about Flight 482: a. Members of the flight crew are paid fixed annual salaries, whereas the flight attendants are paid by the flight. b. One-third of the liability insurance is a special charge assessed against Flight 482 because, in the opin- ion of the insurance company, the destination is in a high-risk area. The remaining two-thirds would be unaffected by a decision to drop Flight 482. C. The baggage loading and flight preparation expense is an allocation of ground crew's salaries and depreciation of ground equipment. Dropping Flight 482 would have no effect on the company's total baggage loading and flight preparation expenses. d. If Flight 482 is dropped, Pegasus Airlines has no authorization at present to replace it with another flight. e. Depreciation of aircraft is due entirely to obsolescence. Depreciation due to wear and tear is negligible. f. Dropping Flight 482 would not allow Pegasus Airlines to reduce the number of aircraft in its fleet or the number of flight crew on its payroll. Required: 1. Prepare an analysis showing what impact dropping Flight 482 would have on the airline's profits. 2. The airline's scheduling officer has been criticized because only about 50% of the seats on Pegasus's flights are being filled, compared with an average of 60% for the industry. The scheduling officer has explained that Pegasus's average seat occupancy could be improved considerably by eliminating about 10% of the flights, but that doing so would reduce profits. Explain how this could happen. PROBLEM 9-4 Determining Whether to Make or Buy [LO1 - CC4] Troy Engines Ltd. manufactures a variety of engines for use in heavy equipment.
