5. Charter contracts are negotiable, and charter carriers receive many contract offers that do not promise $300 prices or 80-percent-full planes. Should the airline accept a charter flight proposal from a group that offers to guarantee the sale of 90 seats at $250? Why or why not?Suppose the following costs for a 10-hour round-trip flight apply to the time frame and expenses of an unscheduled 5-hour charter flight from Baltimore to Las Vegas (and return the next day) on a seven-year-old Boeing 737-800 with 120 occupied seats. Some costs listed in the table have been aggregated up to the flight level from a seat-level decision where they are incurred. Others have been allocated down to the flight level from an entry/exit or maintain-ownership company-level decision. Still other costs vary with the goo go flight-level decision itself. Your job is to analyze each cost item and figure out the "behavior of cost"-that is, with which decision each cost varies.
