Friday, October 10, 2014 - The U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) today issued its annual directive detailing the requirements for the reporting of airline on-time data for calendar year 2015. In 2015, BTS will receive reports from 14 airlines. Spirit Airlines will be required to report for the first time in 2015 while Southwest Airlines and AirTran Airways will begin reporting jointly. American Airlines and US Airways will continue to report separately. Airlines with revenue of more than 1 percent of the total scheduled-service domestic passenger revenue for all airlines for the 12-months ending June 30, 2014, are required to report.

The directive also includes a list of 29 airports with 1 percent or more of the nation's total domestic scheduled-service passenger enplanements for the 12-months ending June 30, 2014, for which monthly on-time reports are required. The list is unchanged from 2014. Although all reporting airlines voluntarily report on all domestic airports they serve, these 29 airports are listed in the detailed airport tables of the Department’s Air Travel Consumer Report and on BTS’ major airport on-time rankings. For the complete list of carriers required to report data in 2015 and the airports for which reports are required, see Technical Directive 24.   Contact: Dave Smallen: 202-366-5568.
