Delay causes
Why UA 2463 runs late
National Airspace System accounts for 58% of the 7,170 delay minutes carriers reported here, and the remaining four split what is left.
- 58%National Airspace System
- 18%Carrier
- 17%Late-arriving aircraft
- 7%Extreme weather
58% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 4,139 minutes out of 7,170, against a national NAS share of 21%. The split is drawn from 7,170 delay minutes reported on UA 2463.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and routes
What a delay on this flight costs
9.2% 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 758 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on three other city pairs in the data, including RDU to IAD (210), SEA to IAD (47) and MCO to DEN (15), but none flew often enough under UA 2463 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAD to MCO only.
One caution: this is a thin sample. 365 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.
