ABSTRACT
Airline management invests all of its effort to develop profitable schedules that are satisfactorily competitive in the different markets. This effort entails collecting and processing a significant amount of information related to market demand, air carrier competition, airport capacity, fleet size, maintenance requirements, crew working rules, aviation regulations, and so on. During normal operation conditions, the airline is expected to operate its planned schedule smoothly with slight or no modifications. However, when adverse weather conditions are anticipated, several safety regulations are imposed by the aviation administration to guarantee safe operation. These safety regulations are usually in the form of a capacity reduction on runways at airports that have adverse weather conditions. This capacity reduction represents a decrease in the number of flights that can land at the airport. Accordingly, the airline schedule is expected to be disrupted due to the imposed capacity reduction.
