These figures cover 320 flights between July 2025 and June 2026. Beyond the headline rate, 8.6% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When UA 576 flies

UA 576 flies MSP to ORD without a single fixed slot. Its most common scheduled departure was 11:27, used on 78 of 320 flights, with 11:20 (56 flights) and 11:32 (41 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 11:27 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 576 runs 7 points worse at 72.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 576 quarter by quarter

By weekday, UA 576 did best on Tuesday at 85.1% on time and worst on Friday at 57.8%. Each day rests on about 46 flights, so a gap of 27 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 576 runs late

One category carries most of the weight here. National Airspace System accounts for 45% of the 5,775 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
44%
Carrier
11%
Extreme weather
0%

44% 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 5,775 reported delay minutes here, that single category outweighs weather by 44 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 5,775 delay minutes reported on UA 576.

Cancellations sit at 1.88% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

8.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

UA 576 is not only a MSP to ORD flight. It also flew ORD to LAX (297 flights, 73.6% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 320 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.
