NOTE
As of 2008, the FAA now reports delays for aircraft that accumulate a delay of 15 minutes or more throughout the duration of the flight. Each holding segment is recorded as one delay. OPSNET delay data dating back to the year 2000 have been converted to be consistent with the new definitions.
2008 Airport terminal volume data includes Air Route Traffic Control Center volume data.
Numbers may not add to totals due to rounding.
