These figures cover 359 flights between July 2025 and June 2026. Beyond the headline rate, 15.6% 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 1923 flies

UA 1923 flies ORD to CID without a single fixed slot. Its most common scheduled departure was 20:10, used on 73 of 359 flights, with 20:20 (64 flights) and 20:05 (43 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 20:10 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and UA 1923 runs 10 points worse at 60.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

UA 1923 quarter by quarter

Quarter by quarter UA 1923 held fairly steady: 55.1% in Jul–Sep 2025, 64.7% in Oct–Dec 2025, 61.8% in Jan–Mar 2026 and 61.8% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, UA 1923 did best on Tuesday at 75.0% on time and worst on Thursday at 45.8%. Each day rests on about 51 flights, so a gap of 29 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1923 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 64% of the 13,000 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.

64%
Carrier
20%
National Airspace System

Extreme weather
8%

64% 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 13,000 reported delay minutes here, that single category outweighs weather by 8 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 13,218 delay minutes reported on UA 1923.

Cancellations sit at 1.67% against a national 1.81%, which is ordinary. Diversions add another 0.28%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 15.6% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The same number turns up on two other city pairs in the data, including DEN to ORD (30) and SLC to ORD (24), but none flew often enough under UA 1923 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to CID only.

One caution: this is a thin sample. 359 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 1923

For a booking, UA 1923 is a flight to put a long connection behind. 15.6% 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.
