Delay causes
Why OO 5772 runs late
Late-arriving aircraft accounts for 55% of the 7,181 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 20%Extreme weather
- 13%Carrier
- 12%National Airspace System
Extreme weather accounts for 20% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.3 times the usual weather exposure. The split is drawn from 7,181 delay minutes reported on OO 5772.
Cancellations sit at 2.34% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
11.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The same number turns up on two other city pairs in the data, including ORD to CID (13) and ORD to GRR (2), but none flew often enough under OO 5772 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ASE to DEN only.
One caution: this is a thin sample. 299 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking OO 5772
For a booking, read OO 5772 as 76.7% on time with 2.34% cancelled over 299 flights. Those are rates from the past twelve months, not a forecast for any particular day.
