These figures cover 261 flights between July 2025 and June 2026. The median arrival is 13 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.

Schedule

When UA 1144 flies

UA 1144 flies JAX to EWR without a single fixed slot. Its most common scheduled departure was 09:40, used on 37 of 261 flights, with 10:40 (37 flights) and 11:00 (29 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 09:40 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 1144 runs 7 points better at 90.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

UA 1144 quarter by quarter

Quarter by quarter UA 1144 held fairly steady: 93.6% in Jul–Sep 2025, 87.7% in Oct–Dec 2025, 88.5% in Jan–Mar 2026 and 93.5% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202547 flights93.6%

Jan–Mar 202663 flights88.5%

By weekday, UA 1144 ranged from 87.8% on Monday to 95.1% on Friday. With about 37 flights behind each day, a spread of 7 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 1144 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 55% of the 3,133 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Late-arriving aircraft
55%
National Airspace System
29%
Carrier
15%

55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,133 reported delay minutes here, that single category outweighs weather by 55 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,133 delay minutes reported on UA 1144.

Cancellations are rare at 0.77%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.3% land an hour or more behind schedule, against 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The same number turns up on seven other city pairs in the data, including EWR to CHS (113), EWR to ORD (49) and ORD to ONT (48), 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. 261 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: 90.7% on time and 0.77% cancelled. That is a base rate, not a promise about any single day.
