* Current month minus same month previous year. This is generally used in the case of bound numbers, such as proportions that cannot exceed 100%.

NOTES: The current value is compared to the value from the same period in the previous year to account for seasonality. Data are available for those carriers that had at least 1% of domestic enplanements in the previous year. The last 25 months of data include only carriers that reported in each of the last 25 months to retain comparability. Earlier data includes all reporting carriers.

A scheduled operation consists of any nonstop segment of a flight. The term "late" is defined as 15 minutes after the scheduled departure or arrival time. A “cancelled” flight is a flight that was not operated but was in the carrier's computer reservation system within 7 days of the scheduled departure. A “diverted” flight is a flight which is operated from the scheduled origin point to a point other than the scheduled destination point in the carrier's published schedule.
