These figures cover 326 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 1368
The latest arrival of the period was on 27 January 2026, 3 hours 7 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 January 2026 | 3 hours 7 minutes | Late-arriving aircraft |
| 29 July 2026 | 2 hours 40 minutes | Carrier |
| 28 January 2026 | 2 hours 36 minutes | Late-arriving aircraft |
| 1 June 2026 | 2 hours 19 minutes | National Airspace System |
| 17 July 2026 | 2 hours 2 minutes | Late-arriving aircraft |
Delay causes
Why UA 1368 runs late
Late-arriving aircraft accounts for 53% of the 2,039 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 25%National Airspace System
- 22%Carrier
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,039 reported delay minutes here, that single category outweighs weather by 53 to one. The split is drawn from 2,039 delay minutes reported on UA 1368.
Cancellations are rare at 0.31%, below the national 1.89% 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 4.0% 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.
At 2,733 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 one other city pair in the data, including DEN to LAX (185), but none flew often enough under UA 1368 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SJU to DEN only.
One caution: this is a thin sample. 326 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 1368
For a booking, UA 1368 has one of the better records a US domestic flight can show: 88.8% on time and 0.31% cancelled. That is a base rate, not a promise about any single day.
