How I Built a Delay Risk Score for 628,000 Flights
Every flight in the MyAirports API includes a delayRisk object. It looks like this:
{
"flightNumber": "VY1234",
"scheduledTime": "2026-04-21T07:15:00Z",
"status": "scheduled",
"insights": {
"delayRisk": {
"onTimePct": 61,
"avgDelayMinutes": 28,
"cancelledPct": 3.2,
"sample": 89,
"context": "VY MAD→BCN, Mon morning"
}
}
}
Three numbers. Looks...
