Delay causes
Why OO 5549 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 11,000 reported delay minutes.
- 42%Extreme weather
- 31%Carrier
- 21%Late-arriving aircraft
- 7%National Airspace System
Extreme weather accounts for 42% 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 7.0 times the usual weather exposure. The split is drawn from 10,856 delay minutes reported on OO 5549.
Cancellations sit at 0.92% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
11.5% 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 one other city pair in the data, including ABQ to IAH (1), but none flew often enough under OO 5549 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDD to SFO only.
One caution: this is a thin sample. 325 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 5549
For a booking, read OO 5549 as 84.2% on time with 0.92% cancelled over 325 flights. Those are rates from the past twelve months, not a forecast for any particular day.
