These figures cover 292 flights between September 2025 and August 2026. The median arrival is 12 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.

Delay causes
Why UA 1144 runs late
Late-arriving aircraft accounts for 50% of the 4,436 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 28%Carrier
- 21%National Airspace System
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,436 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 4,436 delay minutes reported on UA 1144.
Cancellations sit at 1.03% against a national 1.89%, which is ordinary. Diversions add another 0.68%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.5% 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 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 six other city pairs in the data, including EWR to CHS (113), CMH to IAD (21) and MSP to SFO (5), but none flew often enough under UA 1144 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JAX 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 1144
For a booking, UA 1144 has one of the better records a US domestic flight can show: 88.2% on time and 1.03% cancelled. That is a base rate, not a promise about any single day.
