Delay causes
Why UA 1611 runs late
Late-arriving aircraft accounts for 61% of the 9,033 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Late-arriving aircraft
- 21%Carrier
- 15%National Airspace System
- 4%Extreme weather
61% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,033 reported delay minutes here, that single category outweighs weather by 17 to one. The split is drawn from 9,033 delay minutes reported on UA 1611.
Cancellations run at 3.51%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
16.9% 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 FLL to EWR (124), SNA to EWR (60) and MSY to EWR (31), but none flew often enough under UA 1611 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to CLE only.
One caution: this is a thin sample. 313 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 1611
For a booking, the cancellation rate is the figure to plan around on UA 1611: 3.51% of its 313 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
