(monthly data)
Excel | CSV | Table Version
The
number of flights arriving on time is a measure of service quality. This
indicator is strongly seasonal and is affected by weather and heavy demand in
winter and summer months, respectively. The data cover those airlines that
enplaned at least 1% of demestic passengers in the previous year, and have
also reported for at least two consecutive years. A scheduled operation consists of any
nonstop segment of a flight. An on time
flight arrives within 15 minutes of the scheduled arrival time.
