Late-arriving aircraft accounts for 71% of the 8,879 delay minutes carriers reported here, and the remaining four split what is left.
- 71%Late-arriving aircraft
- 25%Carrier
- 4%National Airspace System
71% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,879 reported delay minutes here, that single category outweighs weather by 71 to one. The split is drawn from 8,879 delay minutes reported on UA 2626.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.34%.
Connections and routes
What a delay on this flight costs
17.1% 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 2,565 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 two other city pairs in the data, including DEN to TYS (1) and SDF to SFO (1), but none flew often enough under UA 2626 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to EWR only.
One caution: this is a thin sample. 292 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 UA 2626
For a booking, UA 2626 is a flight to put a long connection behind. 17.1% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
