For the monthly number of carriers reporting, please refer to the Air Travel Consumer Reports available at http://airconsumer.dot.gov/reports/index.htm. A flight is considered delayed when it arrived 15 or more minutes later than scheduled. Average minutes are calculated for delayed flights only. Percents may not add to 100 due to rounding.
