Late departures 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 time. The number of carriers reporting beginning in 2010 is 18. The number of carriers reporting in 2008 and 2009 is 19 (20 through February 2008, after which Aloha Airlines ceased reporting).
