Because of the statistically significant increase in several measures of pilot behavior (isolated among its East pilots), the reliability of US Airways’ East operations has been adversely affected, imposing significant costs on the Company and causing substantial inconvenience for US Airways’ passengers. For example, a regression model controlling for daily weather variation and other factors, indicates that pilot actions since May 1st have added more than six minutes of delay (on average) to East mainline and Charlotte mainline flights. In aggregate, this has resulted in over 8,000 hours of East flight delays since May 1st. Moreover, when this model is applied to the Company’s West mainline and Express operations (those performed by US Airways’ regional carrier partners), no statistically significant change is found.
• A similar regression analysis (also controlling for weather and other factors) indicates that East pilot actions since May 1, 2011 have resulted in a nearly 11 percentage point degradation in the percentage of the Company’s East operations that arrived within 14 minutes of their scheduled arrival time (historically, approximately 79% of US Airways’ East flights arrived ontime by this metric). Put differently, this has resulted in over 8,000 additional East mainline flight delays since May 1st. In Charlotte, the impact has been even larger, at 12 percentage points (resulting in approximately 2,500 flight delays since May 1st). This metric, known throughout the industry as “A:14” is used by the U.S. Department of Transportation to compare on-time performance across carriers. Moreover, when this model is applied to the Company’s West mainline and Express operations, no statistically significant change is found.
