What is the minimum threshold beyond which delays tend to increase exponentially?

The concept of a minimum threshold beyond which delays tend to increase exponentially relates to the psychological and operational responses to time losses in various scenarios, including aviation and transportation. In many studies and real-world applications, research has indicated that a threshold of 4-6 minutes is significant. This duration represents a point at which passengers and operational systems begin to exhibit heightened sensitivity and frustration to delays, leading to compounding effects that exacerbate the situation.

When delays exceed this threshold, both system inefficiencies and passenger behaviors can contribute to a snowball effect, resulting in significantly longer delays. The logistics of managing schedules, coordinating arrival and departure times, and maintaining overall flow are all disrupted after the four to six-minute mark, as systems that were designed to operate efficiently begin to fail under the increased load.

Understanding this minimum threshold is essential for effective operational planning and responding to delays in a way that minimizes impact on passenger experience and ensures operational efficiency.
