On time means landing no more than 15 minutes after the scheduled arrival, late more than 15 minutes after, both times read to the minute. The percentages share one base: graded arrivals plus cancelled and diverted flights. A cancelled plan another plan of the flight replaced within 12 hours is not counted. Median and “9 in 10” are interpolated over the graded arrivals. Compares scheduled and actual arrival times, read to the minute. Some flights may be missing.
