UA 2354 earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%.

These figures cover 297 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 2354 flies
UA 2354 flies DEN to MCO without a single fixed slot. Its most common scheduled departure was 09:50, used on 69 of 297 flights, with 10:10 (41 flights) and 10:11 (37 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 09:50 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 2354 runs level with that at 84.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route
UA 2354 next to DEN to MCO

Across the year
UA 2354 quarter by quarter
Quarter by quarter UA 2354 held fairly steady: 83.7% in Jul–Sep 2025, 88.5% in Oct–Dec 2025, 83.5% in Jan–Mar 2026 and 82.0% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202543 flights83.7%
- Oct–Dec 202578 flights88.5%
- Jan–Mar 202685 flights83.5%

By weekday, UA 2354 did best on Tuesday at 90.7% on time and worst on Monday at 76.2%. Each day rests on about 42 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2354 runs late
One category carries most of the weight here. National Airspace System accounts for 43% of the 2,280 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.
- 43%National Airspace System
- 36%Late-arriving aircraft
- 21%Carrier
36% 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 2,280 reported delay minutes here, that single category outweighs weather by 36 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 2,280 delay minutes reported on UA 2354.
Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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 3.7% 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 1,547 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 four other city pairs in the data, including MCO to EWR (123), SDF to DEN (49) and PHX to DEN (37), but none flew often enough under UA 2354 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to MCO only.
One caution: this is a thin sample. 297 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 2354
For a booking, read UA 2354 as 84.4% on time with 0.00% cancelled over 297 flights. Those are rates from the past twelve months, not a forecast for any particular day.
