In addition, the reporting carriers canceled 2.5 percent of their scheduled domestic flights in January, an improvement over the 6.5 percent cancellation rate posted in January 2014, but up from the 1.4 percent rate in December 2014.
January marks the first month in which Spirit Airlines was required to report on-time performance and mishandled baggage data to the Department. It becomes a ranked carrier in those sections of the report.
Additionally, AirTran Airways no longer appears as a ranked carrier in the report as result of the completion of its merger with Southwest Airlines in December 2014.
American Airlines and US Airways, following their December 2013 merger announcement, will report separately until the Department approves single carrier reporting and a single economic certificate is issued.
