The main task of Revenue Management is to gain maximum possible revenue by selling defined numbers of airplane seats for specific fares to identified market segments. RM has the continuous challenge of selling the right price to the right customer at the right time. The objective of RM is to optimize and maximize revenues. The principle of RM is that a seat at a lower fare could never be sold at a higher fare at the same time, taking all customer segments into account. The RM department is one of the key departments for any airline, but it relies on good communication between other key departments in order to reach its goals.
