UA 1182 earns an F, which is as low as this site's scale goes for a reason. Only 37.7% of flights arrive inside the 15-minute window, 40 points worse than the national rate of 77.6%. Late arrivals average an hour and a half. Treat any tight connection here as a coin flip. That rests on 282 flights, with a median arrival 25 minutes late.

The national on-time rate over the same period is 77.6%, so UA 1182 runs 40 points behind the country as a whole. Across a thousand flights that is about 399 extra late arrivals.

These figures cover 282 flights between July 2025 and June 2026. Beyond the headline rate, 25.0% 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 1182 flies

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

A 17:52 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 1182 runs 31 points worse at 37.7%. 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 1182 quarter by quarter

UA 1182 did not run the same all year. Its best quarter was Jan–Mar 2026 at 50.0% on time and its weakest Jul–Sep 2025 at 28.4%, a swing of 22 points on roughly 71 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, UA 1182 did best on Saturday at 53.3% on time and worst on Sunday at 33.3%. Each day rests on about 40 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1182 runs late

One category carries most of the weight here. National Airspace System accounts for 50% of the 16,000 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.

50% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 8,045 minutes out of 16,000, against a national NAS share of 21%. The split is drawn from 15,974 delay minutes reported on UA 1182.

Cancellations sit at 2.13% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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. 25.0% 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 ten other city pairs in the data, including ORD to SJC (131), ORD to SAN (48) and IAH to DEN (37), but none flew often enough under UA 1182 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CMH to ORD only.

One caution: this is a thin sample. 282 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 1182

For a booking, UA 1182 is a flight to put a long connection behind. 25.0% 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.
