Flight schedules that allow for a little carefully designed wiggle room could prevent the frustration of cascading airport delays and cancellations. By focusing on the early phases of flight schedule planning and delays at various scales, researchers have developed models to help create schedules that are less susceptible to delays and easier to fix once disrupted.

A reduction in delays, cancellations, and their cascading downstream impacts would greatly benefit the U.S. airline industry and travelers. Existing models are unable to distinguish the cascading downstream impact of one solution over another.
