How it settles
We read the arrival time the destination airport publishes, against its published schedule. A flight that arrives more than the delay threshold late settles "Delayed"; one that arrives exactly on the threshold settles "On time". The threshold and the scheduled arrival it is measured against are fixed when the market opens — so the outcome is decided by the flight, not by anyone here.
This market's delay threshold is 15 minutes.
