Singapore Airlines (SIA) will lower its fuel surcharges for travelers in Business and Economy Class, across all routes, for tickets issued on or after Nov. 7, 2008. The reduction is the second time since September 2008 that Singapore Airlines has reduced fuel surcharges, in line with the recent sustained fall in the price of jet fuel. Besides the length of the journey, the surcharge levels will hereafter also take into account the class of travel. This is to fairly impute fuel related cost since the space occupied and weight utilized in each class is different. Despite the recent easing of jet fuel prices, collections from fuel surcharges only partially offset the increased expenditure on jet fuel. Singapore Airlines will keep jet fuel prices under constant review, as they remain volatile. Any changes in the application of surcharges will be based on trend price movements in the price of jet fuel.
