Recorded outcomes

  • On time 80.5% 5,131
  • Delayed >15 min 18.9% 1,207
  • Cancelled 0.5% 32
  • Missing departure time 0.0% 0

All recorded flights with a known scheduled local time, counted once. Missing actual times are shown separately.

On time means departing no more than 15 minutes after schedule. Cancelled flights and flights missing departure times are excluded from the on-time rate and average delay.
