These figures cover 346 flights between September 2025 and August 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.

A 10:10 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and UA 2354 runs level with that at 84.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Arrival by arrival
How late UA 2354 runs when it is late
UA 2354 often beats the schedule: 113 of 343 completed flights, 33%, arrived 15 minutes or more early. Most of the lateness is short. 27 of the 54 late arrivals were under half an hour behind, and 12 reached an hour or more.

Share of 343 completed flights by arrival against schedule.
6 of 39 late departures made up the time and arrived on time, 15% of them. In the other direction, 21 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MCO.
The worst days
Worst days for UA 2354
The latest arrival of the period was on 16 March 2026, 5 hours 27 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across March, September and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 March 2026 | 5 hours 27 minutes | National Airspace System |
| 2 September 2025 | 2 hours 53 minutes | Late-arriving aircraft |
| 8 August 2026 | 2 hours 33 minutes | Carrier |

Delay causes
Why UA 2354 runs late
National Airspace System accounts for 44% of the 2,676 delay minutes carriers reported here, and the remaining four split what is left.
- 44%National Airspace System
- 35%Late-arriving aircraft
- 21%Carrier
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,676 reported delay minutes here, that single category outweighs weather by 35 to one. The split is drawn from 2,676 delay minutes reported on UA 2354.
Cancellations are rare at 0.00%, below the national 1.89% 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 3.5% 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 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), PHX to DEN (37) and TUS to DEN (24), 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. 346 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
