The negative impacts of flight delays and disruptions are well documented. Globally, flight delays are estimated to cost over 60 billion USD, and in the U.S. two out of every three flight delays are caused by somewhat predictable events, such as weather, air traffic control restrictions, or another forecastable cause. Most critical for travel agencies and travel management companies (TMCs) is the personal impact on the traveler: over half of all business travelers list delays and cancellations as the most frustrating part of travel.
