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.

By weekday, UA 2189 did best on Tuesday at 68.4% on time and worst on Sunday at 51.2%. Each day rests on about 39 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Share of 258 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 80 departures that left 15 minutes late or more, only 8 made it up before arrival. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LGA.
The worst days
Worst days for UA 2189
The latest arrival of the period was on 27 July 2026, 7 hours 26 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 July 2026 | 7 hours 26 minutes | Late-arriving aircraft |
| 7 December 2025 | 5 hours 34 minutes | Late-arriving aircraft |

Delay causes
Why UA 2189 runs late
National Airspace System accounts for 46% of the 8,624 delay minutes carriers reported here, and the remaining four split what is left.
- 46%National Airspace System
- 34%Late-arriving aircraft
- 14%Carrier
- 6%Extreme weather
46% 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 4,004 minutes out of 8,624, against a national NAS share of 21%. The split is drawn from 8,624 delay minutes reported on UA 2189.
Cancellations run at 4.43%, against 1.89% nationally. That is roughly one flight in 25 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
17.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
The same number turns up on six other city pairs in the data, including TPA to ORD (164), LGA to IAH (40) and ORD to MSP (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. 271 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: 4.43% of its 271 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
