“I know you’ve got a plane to catch, but let me try to explain it once again to you, sir,” pleads Karan Joel, a marketing manager for Jetset Airlines. Karan has been attempting (unsuccessfully) to explain the airline’s new policy for accumulating miles for awards (such as upgrades to first class and free flights) to a member of Jetset’s “Cool Flyers” club. Karan takes another pass at getting the policy off the ground, saying, “You see, sir, the traveler (that’s you, Mr. Topol) will be awarded the miles actually flown. If the actual mileage for the leg was less than 400 miles, the traveler will get 400 miles of credit. If the trip was made on a Saturday, the actual mileage will be multiplied by two. If the trip was made on a Tuesday, the multiplication factor is 1.5. If this is the eighth leg traveled during the calendar month, the mileage is doubled no matter what day, and if it is the 16th leg traveled, the mileage is tripled. If the traveler booked the flight on the Web, our app, or through a travel service such as Expedia, 100 miles are added. “I hope that clears it up for you, Mr. Topol. Enjoy your flight, and thanks for flying Jetset.” Mr. Topol, whose desire to board the Jetset plane has all but melted away during Karan’s long explanation, fades into the sea of people wading through the security lanes, without so much as a peep in reply. Develop a decision tree for Jetset Airlines’ new policy for accumulating award miles so that the policy becomes clearer, is easier to grasp visually, and hence is easier to explain
