UA 2137 lands a B, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 302 flights, with a median arrival 2 minutes early.

These figures cover 302 flights between July 2025 and June 2026. The median arrival is 2 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.

Schedule

When UA 2137 flies

UA 2137 is scheduled to leave Madison (MSN) at 06:30 local time and reach Chicago (ORD) at 07:37. That slot held for 244 of the 302 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

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

A 06:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2137 runs 11 points worse at 78.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

UA 2137 next to MSN to ORD

Across its whole network United Airlines managed 79.0%, close to this flight's figure.

Across the year

UA 2137 quarter by quarter

UA 2137 did not run the same all year. Its best quarter was Apr–Jun 2026 at 88.2% on time and its weakest Oct–Dec 2025 at 67.1%, a swing of 21 points on roughly 76 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.

Jul–Sep 202590 flights84.1%
Oct–Dec 202578 flights67.1%
Jan–Mar 202681 flights78.2%
Apr–Jun 202653 flights88.2%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, UA 2137 did best on Thursday at 87.8% on time and worst on Sunday at 71.4%. Each day rests on about 43 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2137 runs late

One category carries most of the weight here. National Airspace System accounts for 58% of the 3,957 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.

39%
Extreme weather
2%
Late-arriving aircraft
1%

The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,531 of the 3,957 delay minutes reported here. The split is drawn from 3,957 delay minutes reported on UA 2137.

Cancellations run at 2.98%, against 1.81% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

5.8% 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.

The same number turns up on eight other city pairs in the data, including ORD to ORF (106), ORD to LAS (87) and ORD to SLC (86), but none flew often enough under UA 2137 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSN to ORD only.

One caution: this is a thin sample. 302 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 2137

For a booking, the cancellation rate is the figure to plan around on UA 2137: 2.98% of its 302 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
