A regional airline, Northwest Commuter, has started operating on the west coast of the United States. It has become established as a no-frills airline providing low-cost commuter flights between the west coast cities of

Seattle, Portland, and San Francisco. The company has been able to achieve fast turnaround times between flights, but in order to further keep the costs low, the management needs to find new ways for Northwest

Commuter to become a more efficient airline. In particular, management wants to start by dropping unprofitable flights and then identifying the most profitable flights.

Three airplanes have been leased and the leasing cost for each airplane

is $30,000 per day, that is incurred at 12 midnight every day. At the end of

the day, an airplane might remain in the city where it landed on its last

flight. Another option is to fly empty overnight to another city to be ready

to start a flight from there the next morning. The cost of this latter option is

$5,000.

The following table shows the 22 possible flights that are being

considered for the coming year. The last column gives the estimated net

revenue (in thousands of dollars) for each flight, given the average

number of passengers anticipated for that flight. To simplify the analysis,

assume for now that there is virtually no turnaround time between flights

so the next flight can begin as soon as the current flight ends. If an

immediate next flight is not available, the airplane would wait in the airport

until the next scheduled flight from that city.
