These figures cover 333 flights between July 2025 and June 2026. The median arrival is 9 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 1368 flies

UA 1368 flies SJU to DEN without a single fixed slot. Its most common scheduled departure was 13:40, used on 143 of 333 flights, with 14:25 (126 flights) and 14:00 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 13:40 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1368 runs 8 points better at 86.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 1368 quarter by quarter

UA 1368 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.1% on time and its weakest Jul–Sep 2025 at 74.1%, a swing of 16 points on roughly 83 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jan–Mar 202690 flights89.9%

By weekday, UA 1368 did best on Thursday at 93.3% on time and worst on Sunday at 80.9%. Each day rests on about 48 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1368 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 2,105 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
48%
National Airspace System
38%
Carrier
14%

48% 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 2,105 reported delay minutes here, that single category outweighs weather by 48 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 2,105 delay minutes reported on UA 1368.

Cancellations are rare at 0.30%, 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 3.4% 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 2,733 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 (247), 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. 333 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: 86.9% on time and 0.30% cancelled. That is a base rate, not a promise about any single day.
