These figures cover 308 flights between September 2025 and August 2026. The median arrival is 11 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

The worst days
Worst days for UA 1289
The latest arrival of the period was on 15 June 2026, 5 hours 24 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 15 June 2026 | 5 hours 24 minutes | Late-arriving aircraft |
| 5 June 2026 | 4 hours 46 minutes | Carrier |
| 2 February 2026 | 4 hours 16 minutes | Extreme weather |

Delay causes
Why UA 1289 runs late
Carrier accounts for 51% of the 2,218 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Carrier
- 22%Late-arriving aircraft
- 14%Extreme weather
- 13%National Airspace System
Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.3 times the usual weather exposure. The split is drawn from 2,218 delay minutes reported on UA 1289.
Cancellations run at 2.92%, against 1.89% nationally. That is roughly 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
Badly late arrivals are rare here: only 3.0% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 628 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 SEA (62), DEN to OKC (31) and LAX to DEN (31), but none flew often enough under UA 1289 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CHS to EWR only.
One caution: this is a thin sample. 308 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 1289
For a booking, the cancellation rate is the figure to plan around on UA 1289: 2.92% of its 308 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.
