OIG is conducting an ongoing audit related to air carrier flight delays and cancellations, originally announced on February 21, 2023. Due to the breadth of data collected by both the Federal Aviation Administration and the Bureau of Transportation Statistics (BTS) on flight delays and cancellations, we are adjusting our audit to focus on the reliability of the flight delay and cancellation data collected by BTS. Our revised audit objective is to assess the controls BTS has in place to ensure the completeness and accuracy of on-time performance and reported causes data.
