| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 June 2026 | 9 hours 36 minutes | Carrier |

Delay causes
Why UA 2335 runs late
Late-arriving aircraft accounts for 58% of the 6,591 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 27%Carrier
- 8%National Airspace System
- 7%Extreme weather
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,591 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 6,591 delay minutes reported on UA 2335.
Cancellations run at 3.76%, against 1.89% nationally. That is about one flight in 25 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
13.3% 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 820 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 five other city pairs in the data, including EWR to BUF (31), EWR to CLE (24) and HDN to EWR (21), but none flew often enough under UA 2335 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to JAX only.
One caution: this is a thin sample. 266 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 2335
For a booking, the cancellation rate is the figure to plan around on UA 2335: 3.76% of its 266 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
