These figures cover 296 flights between July 2025 and June 2026. The median arrival is 17 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 2089 flies

UA 2089 flies SJU to ORD without a single fixed slot. Its most common scheduled departure was 07:40, used on 94 of 296 flights, with 08:10 (65 flights) and 07:45 (50 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 07:40 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2089 runs 6 points better at 95.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, UA 2089 ranged from 92.7% on Friday to 100.0% on Thursday. With about 42 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 2089 runs late

One category carries most of the weight here. Carrier accounts for 74% of the 578 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.

Carrier
74%
National Airspace System
26%

The largest share of delay minutes, 74%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 430 of the 578 delay minutes reported here. The split is drawn from 578 delay minutes reported on UA 2089.

Cancellations sit at 1.01% against a national 1.81%, which is ordinary. Diversions add another 0.34%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 0.7% 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.

At 2,072 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on three other city pairs in the data, including EWR to PDX (31), SEA to EWR (23) and IAH to SEA (23), but none flew often enough under UA 2089 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SJU to ORD only.

One caution: this is a thin sample. 296 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 2089

For a booking, UA 2089 has one of the better records a US domestic flight can show: 95.5% on time and 1.01% cancelled. That is a base rate, not a promise about any single day.
