Delay causes
Why UA 1197 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 8,556 reported delay minutes.
- 42%Late-arriving aircraft
- 34%National Airspace System
- 22%Carrier
- 3%Extreme weather
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,556 reported delay minutes here, that single category outweighs weather by 15 to one. The split is drawn from 8,556 delay minutes reported on UA 1197.
Cancellations sit at 1.94% against a national 1.89%, which is ordinary. Diversions add another 0.83%.
Connections and routes
What a delay on this flight costs
11.7% 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.
At 1,605 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on four other city pairs in the data, including PBI to EWR (37), MIA to EWR (31) and SEA to EWR (31), but none flew often enough under UA 1197 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to DEN only.
One caution: this is a thin sample. 360 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.
