Should the need arise, however, increasing apron capacity to keep up with growing numbers of runway movements can be very difficult at space-constrained airports. 12.4.2 Airside Delays and Mitigation A natural consequence of limited airside capacity is air traffic congestion and delays. The most widely reported statistic on delays is the number of flights that are �on time.�23 A widely used practice internationally is to classify a flight as being �on time� if it arrives at its destination not later than 15 minutes after its scheduled time of arrival. In 2007, a very large percentage - roughly 26%, up from 22% in 2005 - of all flights by major airlines in the USA were �late� by this definition.24 The percentage of late flights was even higher at some of the most critical hub airports, such as Atlanta, Chicago O�Hare and Newark. It is important to realize that these on-time statistics seriously underreport the true extent of delays, because airlines already introduce an allowance for delay (�schedule padding�) when they prepare their schedules. For example, if the delay-free gate-to-gate time from Airport A to Airport B is 90 minutes, an airline may schedule its flights for 100 minutes, thus allowing a buffer for 10 minutes of delay for each A-to-B flight on the basis of historical flight records - see ElAlj (2003) for an extensive study. Thus, if that flight arrives at Airport B, on a given day, 17 minutes after its scheduled arrival time, it will have actually incurred a delay of 27 minutes relative to the true delay-free gate-to-gate time. A 27-minute delay on what could have been a 90-minute flight implies, of course, an enormous cost for the airline. With continuing growth in the number of flights, airside congestion and delays will be persistent problems at major airports worldwide and may reach crisis proportions in some regions. A few important qualitative points about the characteristics of airside delay are the following. To begin with, delays may occur even during periods when total airside demand is lower than airside capacity. For example, if the average demand (as 22 For example, certain groups of stands may be reserved for only certain airlines or only certain types of flights (e.g., long-range ones or those arriving from or departing for a particular set of countries). 23 In the USA, airlines are required by la
