UA 2299 earns an F−, which is as low as this site's scale goes for a reason. Only 46.5% of flights arrive inside the 15-minute window, 31 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 271 flights, with a median arrival 16 minutes late.
The national on-time rate over the same period is 77.6%, so UA 2299 runs 31 points behind the country as a whole. Across a thousand flights that is about 311 extra late arrivals.

These figures cover 271 flights between July 2025 and June 2026. Beyond the headline rate, 25.2% 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 2299 flies
UA 2299 flies LGA to ORD without a single fixed slot. Its most common scheduled departure was 17:15, used on 157 of 271 flights, with 17:19 (58 flights) and 17:25 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 17:15 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2299 runs 22 points worse at 46.5%. 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 2299 quarter by quarter
UA 2299 did not run the same all year. Its best quarter was Jul–Sep 2025 at 61.1% on time and its weakest Oct–Dec 2025 at 35.7%, a swing of 25 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.
- Jul–Sep 202537 flights61.1%
- Oct–Dec 202571 flights35.7%
- Jan–Mar 202681 flights46.7%
- Apr–Jun 202682 flights49.4%
Scale runs 25% to 65%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2299 ranged from 39.0% on Monday to 50.0% on Tuesday. With about 39 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why UA 2299 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 11,000 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.
- 47%Late-arriving aircraft
- 44%National Airspace System
- 8%Carrier
- 0%Extreme weather
47% 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 11,000 reported delay minutes here, that single category outweighs weather by 47 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 11,296 delay minutes reported on UA 2299.
Cancellations run at 4.80%, against 1.81% nationally. That is about one flight in twenty 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. 25.2% 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 four other city pairs in the data, including EWR to LAS (46), ORD to MCI (18) and DEN to BWI (7), but none flew often enough under UA 2299 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to ORD 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 2299
For a booking, the cancellation rate is the figure to plan around on UA 2299: 4.80% of its 271 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.
