The term "late" is defined as 15 minutes after the scheduled departure or arrival time. Major air carriers are those with 1 percent or more of domestic scheduled-service passenger revenues. In 2003 there were 15 major air carriers. A canceled flight is one that was not operated, but was listed in a carrier's computer reservation system within seven calendar days of the scheduled departure. A diverted flight is one that left from the scheduled departure airport but flew to a destination point other than the scheduled destination point.
