UA 1411 earns an F+, which is as low as this site's scale goes for a reason. Only 47.9% of flights arrive inside the 15-minute window, 29 points worse than the national rate of 77.3%. Late arrivals average close to two hours. Treat any tight connection here as a coin flip. That rests on 266 flights, with a median arrival 18 minutes late.
The national on-time rate over the same period is 77.3%, so UA 1411 runs 29 points behind the country as a whole. Across a thousand flights that is about 294 extra late arrivals.

Share of 261 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 109 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 34 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 ORD.
The worst days
Worst days for UA 1411
The latest arrival of the period was on 2 April 2026, 15 hours 33 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. Three of the five worst days fell in March 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 April 2026 | 15 hours 33 minutes | National Airspace System |
| 10 March 2026 | 12 hours 35 minutes | Extreme weather |
| 6 March 2026 | 7 hours 4 minutes | Late-arriving aircraft |

Delay causes
Why UA 1411 runs late
Late-arriving aircraft accounts for 44% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 40%National Airspace System
- 10%Carrier
- 6%Extreme weather
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 13,901 delay minutes reported on UA 1411.
Cancellations are rare at 0.75%, 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
26.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 888 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on eight other city pairs in the data, including PDX to DEN (184), DFW to IAH (31) and CLE to EWR (24), but none flew often enough under UA 1411 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to ORD only.
One caution: this is a thin sample. 266 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 1411
For a booking, UA 1411 is a flight to put a long connection behind. 26.4% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
