Table 14.4 follows the experience of a new commuter airline during its first eight weeks of business. The average weekly load factors (i.e., percentages of seats sold) show a steady increase, from approximately 30 percent for week 1 to approximately 70 percent for week 8 . In this example, the smoothed value St is calculated using equation (10), which is equation (5) modified by the addition of a trend value Tt1 to the previous smoothed value St1 to account for the weekly rate of increase in the load factor.
