NOTES

Late departures and arrivals are strongly seasonal and are affected by weather and heavy demand in winter and summer months. The term Late is defined as 15 minutes after the scheduled departure or arrival time. A cancelled 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. During 2005-2007, 20 air carriers reported on-time performance data, including all major U.S. carriers (carriers with at least one percent of total domestic scheduled-service passenger revenues) and other carriers that reported voluntarily. The number of carriers reporting in previous years is as follows: 2012 (15); 2011(16); 2010 (18); 2009 (19); 2008 (19; 20 through February after which Aloha Airlines ceased reporting); 2007(20); 2006 ( 20; 19 through March after which Aloha Airlines started reporting for the second time)); 2005 (20; 19 through April after which Frontier Airlines started reporting); 2004 (19); 2003 (17; 18 starting in November when Hawaiian Airlines started reporting); 2002 (10); 2001(12; 11 starting in November when Aloha Airlines ceased reporting for the first time); 2000: (10; 11 starting in November when Aloha Airlines started reporting for the first time); 1999 (10); 1998 (10); 1997 (10); 1996 (10); and 1995 (10).
