Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2189, check with United Airlines.
UA 2189 draws a D. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 270 flights, with a median arrival 2 minutes late.
The national on-time rate over the same period is 77.6%, so UA 2189 runs 14 points behind the country as a whole. Across a thousand flights that is about 144 extra late arrivals.

These figures cover 270 flights between July 2025 and June 2026. Beyond the headline rate, 16.5% 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 2189 flies
UA 2189 is scheduled to leave Chicago (ORD) at 13:00 local time and reach New York (LGA) at 16:13. That slot held for 224 of the 270 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 13:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 2189 runs 16 points worse at 63.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 2189 quarter by quarter
UA 2189 did not run the same all year. Its best quarter was Jan–Mar 2026 at 70.7% on time and its weakest Oct–Dec 2025 at 56.4%, a swing of 14 points on roughly 68 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.

- Oct–Dec 202555 flights56.4%
- Jan–Mar 202663 flights70.7%

By weekday, UA 2189 did best on Wednesday at 70.7% on time and worst on Sunday at 53.7%. Each day rests on about 39 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2189 runs late
One category carries most of the weight here. National Airspace System accounts for 47% of the 7,729 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.
- 47%National Airspace System
- 34%Late-arriving aircraft
- 16%Carrier
- 4%Extreme weather
47% 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 3,633 minutes out of 7,729, against a national NAS share of 21%. The split is drawn from 7,729 delay minutes reported on UA 2189.
Cancellations run at 2.96%, 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.5% 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 733 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on six other city pairs in the data, including TPA to ORD (164), RSW to ORD (49) and LGA to IAH (31), but none flew often enough under UA 2189 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to LGA only.
One caution: this is a thin sample. 270 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 2189
For a booking, the cancellation rate is the figure to plan around on UA 2189: 2.96% of its 270 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
