Delay causes
Why UA 1992 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 6,876 reported delay minutes.
- 42%National Airspace System
- 30%Late-arriving aircraft
- 19%Carrier
- 10%Extreme weather
42% 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 2,864 minutes out of 6,876, against a national NAS share of 21%. The split is drawn from 6,876 delay minutes reported on UA 1992.
Cancellations sit at 1.90% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
11.0% 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 eight other city pairs in the data, including PHX to EWR (82), CLE to EWR (52) and FLL to EWR (37), but none flew often enough under UA 1992 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to IAD only.
One caution: this is a thin sample. 316 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.
