These figures cover 288 flights between September 2025 and August 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.

Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 0.4% 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.
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), IAH to SEA (23) and SEA to EWR (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. 288 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: 96.1% on time and 1.04% cancelled. That is a base rate, not a promise about any single day.
