| Abstract: | Since the September 11, 2001, terrorist attacks, repeated airport closures due to security breaches have imposed substantial costs on travelers, airlines, and government agencies in terms of flight delays and cancellations. Using data from the year following September 11, this study examines how airlines recover flight schedules upon reopening of airports that have been closed for security reasons. As such, this is the first study to empirically examine service quality during irregular airport operations. Our results indicate that economic considerations, particularly the potential revenue per flight, have predictable effects on service quality following airport closures. Airport concentration, hub destination, and various logistical factors also significantly influence flight outcomes. |
